A form of intestinal obstruction caused by the PROLAPSE of a part of the intestine into the adjoining intestinal lumen. There are four types: colic, involving segments of the LARGE INTESTINE; enteric, involving only the SMALL INTESTINE; ileocecal, in which the ILEOCECAL VALVE prolapses into the CECUM, drawing the ILEUM along with it; and ileocolic, in which the ileum prolapses through the ileocecal valve into the COLON.
Viral Nonstructural Proteins
The measurement of infection-blocking titer of ANTISERA by testing a series of dilutions for a given virus-antiserum interaction end-point, which is generally the dilution at which tissue cultures inoculated with the serum-virus mixtures demonstrate cytopathology (CPE) or the dilution at which 50% of test animals injected with serum-virus mixtures show infectivity (ID50) or die (LD50).
RNA consisting of two strands as opposed to the more prevalent single-stranded RNA. Most of the double-stranded segments are formed from transcription of DNA by intramolecular base-pairing of inverted complementary sequences separated by a single-stranded loop. Some double-stranded segments of RNA are normal in all organisms.
Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).
Enzyme-Linked Immunosorbent Assay
An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Infections with organisms of the genus HELICOBACTER, particularly, in humans, HELICOBACTER PYLORI. The clinical manifestations are focused in the stomach, usually the gastric mucosa and antrum, and the upper duodenum. This infection plays a major role in the pathogenesis of type B gastritis and peptic ulcer disease.

A high-Mr glycoprotein fraction from cow's milk potent in inhibiting replication of human rotavirus in vitro. (1/2332)Rotavirus is the major cause of infectious diarrhea in infants and young children all over the world. We have found that a high-M(r) glycoprotein fraction from cow's milk is potent in inhibiting replication of human rotaviruses in vitro. Since the activity seems to be unique and specific, this fraction may be useful as a novel agent for treatment or prevention of rotavirus diarrhea. (+info)
Rotavirus G-type restriction, persistence, and herd type specificity in Swedish cattle herds. (2/2332)G-typing of rotavirus strains enables the study of molecular epidemiology and gathering of information to promote disease prevention and control. Rotavirus strains in fecal specimens from neonatal calves in Swedish cattle herds were therefore characterized by using G1 to -4-, G6-, G8-, and G10-specific primers in reverse transcription (RT)-PCR. Fecal samples were collected from one dairy herd (herd A) for 4 consecutive years and from 41 beef and dairy herds (herd B) experiencing calf diarrhea outbreaks. Altogether, 1, 700 samples were analyzed by group A rotavirus enzyme-linked immunosorbent assay, and 98 rotavirus-positive specimens were selected for G-typing by RT-PCR. The effect of herd type, time, geographic region, and clinical symptoms on the G-type distribution was evaluated. Altogether (herds A and B), G10 was found in 59 (60. 2%) fecal specimens, G6 was found in 30 (30.6%) specimens, G3 was found in 1 (1.0%) specimen, and G8 was found in 1 (1.0%) specimen. Seven (7.1%) fecal specimens were not typeable. Herd type specificity in the G-type distribution was demonstrated in the herds in herd B. In the 6 beef suckler herds, only G6 was detected, while rotavirus strains from the 35 dairy herds were predominantly (54%) G10. The G-type distribution was restricted in herds A and B. Twenty-nine of 30 strains from herd A were characterized as G10. In the vast majority of herds in herd B, a single G-type was identified. The serotype G10 and the electropherotype persisted over time in herd A. No characteristic G-type variation in the geographic distribution of cattle herds in herd B was obvious. There was no difference in the G-type distributions between the strains from clinically and subclinically rotavirus-infected calves in dairy herd A. The results from this study strongly indicate a pronounced stability in the rotavirus G-type distribution in Swedish cattle herds, which emphasizes the importance of continuous preventive measures for control of neonatal calf diarrhea. A future bovine rotavirus vaccine in Sweden should contain G10 and G6 strains. (+info)
Two non-structural rotavirus proteins, NSP2 and NSP5, form viroplasm-like structures in vivo. (3/2332)In rotavirus-infected cells, the non-structural proteins NSP5 and NSP2 localize in complexes called viroplasms, where replication and assembly occur. Recently, we have demonstrated direct interaction of NSP5 with NSP2, and as a consequence of that, up-regulation of NSP5 hyperphosphorylation. To investigate a possible structural role for the NSP2-NSP5 interaction, we analysed the cytoplasmic distribution of the two proteins in transfected cells by immunofluorescence using specific antibodies. Here we report that NSP2 and NSP5 can drive the formation of viroplasm-like structures (VLS) in the absence of other rotaviral proteins and rotavirus replication. Several NSP5 deletion mutants were constructed and expressed in combination with NSP2. Both the N- and C-terminal domains of NSP5 were found to be essential for VLS formation. Only one mutant, with an internal deletion of residues 81-130, was able to interact with NSP2 to form VLS. Analysis of the phosphorylation capacity of the different mutants in vivo indicated that hyperphosphorylation of NSP5 is necessary, but not sufficient, for VLS formation. Our results suggest a role for the non-structural protein NSP5 in the structure of viroplasms mediated by its interaction with NSP2. (+info)
Genetic and antigenic variation of capsid protein VP7 of serotype G1 human rotavirus isolates. (4/2332)The deduced amino acid sequences of the outer capsid protein, VP7, of serotype G1 rotavirus clinical isolates collected over a 6 year period (1990-1995) in Melbourne, Australia, were examined. Phylogenetic analysis characterized the sequences into two discrete clusters representing two of the four global lineages of human G1 VP7 proteins. Antigenic characterization using a panel of serotype G1-specific neutralizing monoclonal antibodies classified lineage II isolates (1990-1993) as monotype G1a while lineage I isolates were classified as monotype G1b (1993-1995). Examination of the sequences of the neutralization epitope regions of VP7 revealed a particular amino acid substitution at residue 94 in region A (Asp --> Ser/Thr) that correlated with lineage and monotype designation. Our results indicated that temporal genetic variation of the VP7 of serotype G1 rotaviruses was associated with changes in the antigenicity of these isolates. (+info)
Rotavirus capsid protein VP5* permeabilizes membranes. (5/2332)Proteolytic cleavage of the VP4 outer capsid spike protein into VP8* and VP5* proteins is required for rotavirus infectivity and for rotavirus-induced membrane permeability. In this study we addressed the function of the VP5* cleavage fragment in permeabilizing membranes. Expressed VP5* and truncated VP5* proteins were purified by nickel affinity chromatography and assayed for their ability to permeabilize large unilamellar vesicles (LUVs) preloaded with carboxyfluorescein (CF). VP5* and VP5* truncations, but not VP4 or VP8*, permeabilized LUVs as measured by fluorescence dequenching of released CF. Similar to virus-induced CF release, VP5*-induced CF release was concentration and temperature dependent, with a pH optimum of 7.35 at 37 degrees C, but independent of the presence of divalent cations or cholesterol. VP5*-induced permeability was completely inhibited by VP5*-specific neutralizing monoclonal antibodies (2G4, M2, or M7) which recognize conformational epitopes on VP5* but was not inhibited by VP8*-specific neutralizing antibodies. In addition, N-terminal and C-terminal VP5* truncations including residues 265 to 474 are capable of permeabilizing LUVs. These findings demonstrate that VP5* permeabilizes membranes in the absence of other rotavirus proteins and that membrane-permeabilizing VP5* truncations contain the putative fusion region within predicted virion surface domains. The ability of recombinant expressed VP5* to permeabilize membranes should permit us to functionally define requirements for VP5*-membrane interactions. These findings indicate that VP5* is a specific membrane-permeabilizing capsid protein which is likely to play a role in the cellular entry of rotaviruses. (+info)
Isolation of a human rotavirus strain with a super-short RNA pattern and a new P2 subtype. (6/2332)Super-short rotavirus strains that have a rearranged gene segment 11 are rarely found in humans, and only five isolates, all from Southeast Asia, have been described in the literature. We report the first isolation in Japan from an infant with severe diarrhea of a rotavirus possessing a super-short RNA pattern. This strain, designated AU19, had a G1 VP7 and is also the first isolate in Japan that possesses a P2 VP4. Furthermore, the P2 VP4 carried by AU19 was divergent in the hypervariable region of the amino acid sequence from the P2A VP4s carried by asymptomatic neonatal strains or from the P2B VP4 carried by porcine rotavirus strain Gottfried. Thus, AU19 is likely to represent a new VP4 subtype, which we propose to call P2C. Given the recent emergence of the P2 VP4s in India, Brazil, and the United States and the role of VP4 in protective immunity, further scrutiny is justified to see whether the emergence of the previously underrepresented P2 VP4 serotype is related to this new P2 subtype.

Genetic and antigenic characterization of a serotype PG9 human rotavirus strain isolated in the United States. (7/2332)During an epidemiologic survey of rotavirus infections established to monitor the prevalent G serotypes circulating in the United States, human PG9, subgroup I rotavirus strains causing symptomatic infections were identified as the fourth most common serotype. In this report we describe the molecular and antigenic characterization of one of these PG9 isolates (US1205). Neutralization and sequencing studies have demonstrated that both outer capsid proteins, VP7 and VP4, of US1205 are closely related to but genetically and antigenically distinguishable from those of standard G9 strains (e.g., F45, WI61) and standard P2A strains (e. g., ST3, M37). Thus the complete antigenic type of US1205 is P2AG9, subgroup I. Sequence analysis of the VP6 and NSP4 genes of US1205 indicates that strain US1205 possessed VP6 subgroup I and NSP4A genotype specificities. Finally, Northern hybridization studies suggest that the PG9 strains are closely related to members of the DS-1 genogroup except for their P VP4 gene, which has been commonly identified in strains of both major human genogroups, and their G9 VP7 gene, which may have been derived by reassortment with a Wa genogroup strain. Examination of historic collections and prospective surveillance of strains will be needed to determine whether this strain has been present for some time or if it is emerging to compete with the other common serotypes of rotavirus.

Enteropathogens and other factors associated with severe disease in children with acute watery diarrhea in Lima, Peru. (8/2332)To evaluate enteropathogens and other factors associated with severe disease in children with diarrhea, 381 children <5 years of age with diarrhea and moderate to severe dehydration (in-patients) and 381 age-, sex-, and date-of-visit-matched children with mild diarrhea (out-patients) presenting to a hospital in Peru, were studied. Rotavirus was detected in 52% of the in-patients and 35% of the out-patients (odds ratio [OR]=2.3, 95% confidence interval [95% CI]= 1.6-3.2); 95% of the rotaviruses among in-patients were of serotypes G1-G4. The risk of severe diarrhea was particularly great in children who were not exclusively breast-fed in early infancy and who also lacked piped water in their homes (for children with both characteristics OR=6.8, 95% CI=3.6-12.8). The high prevalence of rotavirus and its association with severe diarrhea underscores the need for rotavirus vaccines. Interventions to educate mothers and improve access to safe water should augment the impact of rotavirus vaccines in preventing severe diarrhea. (+info)

Welcome to CDC stacks | Full Genomic Characterization of a Novel Genotype Combination, G4P, of a Human Rotavirus Strain...
Since 2004, the Pan American Health Organization (PAHO) has carried out rotavirus surveillance in Latin America and the Caribbean. Here we report the characterization of human rotavirus with the novel G-P combination of G4P, detected through PAHO surveillance in Barbados. Full genome sequencing of strain RVA/Human-wt/BRB/CDC1133/2012/G4P revealed that its genotype is G4-P-I1-R1-C1-M1-A8-N1-T1-E1-H1. The possession of a Genogroup 1 (Wa-like) backbone distinguishes this strain from other P rotavirus strains. Phylogenetic analyses suggested that this strain was likely generated by genetic reassortment between human, porcine and possibly other animal rotavirus strains and identified 7 lineages within the P genotype. The results of this study reinforce the potential role of interspecies transmission in generating human rotavirus diversity through reassortment. Continued surveillance is important to determine if rotavirus vaccines will protect against strains that express the P ...
Immunise - 4.17 Rotavirus
Two oral rotavirus vaccines are available in Australia, and their efficacy and safety in the prevention of rotavirus gastroenteritis have been extensively evaluated.33-39 Both are live attenuated vaccines administered orally to infants, but the component vaccine viruses differ. The human rotavirus vaccine, Rotarix (GlaxoSmithKline), is a live attenuated vaccine containing one strain of attenuated human rotavirus (G1P1A strain). Rotarix protects against non-G1 serotypes on the basis of other shared epitopes. A pentavalent vaccine, RotaTeq (CSL Limited/Merck & Co Inc), contains five human-bovine rotavirus reassortants with the human serotypes G1, G2, G3, G4 and P1A and the bovine serotypes G6 and P7.. In middle- and high-income countries, a course of vaccination with either Rotarix or RotaTeq prevents rotavirus gastroenteritis of any severity in approximately 70% of recipients and prevents severe rotavirus gastroenteritis and rotavirus hospitalisation for 85 to 100% of recipients for up to 3 ...

Recombinant complementary DNA (cDNA) representing gene 9 (the gene encoding the neutralization antigens in VP7 glycoprotein) from OSU (porcine rotavirus serotype 1) and Gottfried (porcine rotavirus serotype 2) strains were used to determine the optimal hybridization conditions which allow specific detection of group A porcine rotaviruses. Probes were prepared by excision of the inserts from the recombinant plasmids and radiolabeling of cDNA with 32P by the random primer extension method. Probes were hybridized at various stringencies with viral RNA from different rotavirus serotypes bound to nylon membranes. Hybridization at low stringency (26% ...
Cell attachment protein VP8* of a human rotavirus specifically interacts with A-type histo-blood group antigen - OpenEmory
As with many other viruses, the initial cell attachment of rotaviruses, which are the major causative agent of infantile gastroenteritis, is mediated by interactions with specific cellular glycans. The distally located VP8* domain of the rotavirus spike protein VP4 (ref. 5) mediates such interactions. The existing paradigm is that sialidase-sensitive animal rotavirus strains bind to glycans with terminal sialic acid (Sia), whereas sialidase-insensitive human rotavirus strains bind to glycans with internal Sia such as GM1 (ref. 3). Although the involvement of Sia in the animal strains is firmly supported by crystallographic studies, it is not yet known how VP8* of human rotaviruses interacts with Sia and whether their cell attachment necessarily involves sialoglycans. Here we show that VP8* of a human rotavirus strain specifically recognizes A-type histo-blood group antigen (HBGA) using a glycan array screen comprised of 511 glycans, and that virus infectivity in HT-29 cells is abrogated by ...

A total of 784 faecal samples collected during the 7 months period, January to July 2010 from children under 5 years old with diarrhoea who were admitted at the 3 referral hospitals; Parirenyatwa Hospital, Harare Hospital and Chitungwiza hospital, were tested for presence of rotavirus antigen using enzyme immune-assay (EIA). Fifty faecal samples from children without diarrhoea were also tested for rotavirus antigen. Sixteen (32 %) of 50 non-diarrhoeal samples and 515 (65.7 %) diarrhoea samples were rotavirus positive. The association between diarrhoea and detection of rotavirus in faecal samples was statistically significant with an overall odds ratio of diarrhoea patients of 4.08 (p,0.0001). The rotavirus diarrhoea prevalence (59.4 %) was high in children ≤ 18 months old diarrhoea patients.

Sequence analysis of rotavirus YM VP6 and NS28 proteins | Microbiology Society
We have determined the nucleotide sequence of genes 6 and 10 of porcine rotavirus YM. When the amino acid sequences of VP6 and NS28, the protein products of genes 6 and 10 respectively, were compared with other published sequences it was evident that the proteins of human rotavirus Wa have the highest degree of identity with rotavirus YM. This is in contrast with the observation that when other proteins of these two strains have been compared they have been found to be among the most distantly related pairs of rotavirus strains. This observation is in accordance with the proposed receptor-ligand interaction between NS28 and VP6 during virus morphogenesis, and suggests a specificity in the interaction between these two proteins. In addition, when rotavirus YM VP6, which belongs to subgroup I, was compared with the VP6 proteins of rotavirus strains having different subgroup specificities, it was found to be more closely related to subgroup II rather than subgroup I proteins. This finding allowed us to

Rotavirus, the most common diarrheal pathogen in children worldwide, causes approximately one third of diarrhea-associated hospitalizations and 800,000 deaths per year. Because natural infection reduces the incidence and severity of subsequent episodes, rotavirus diarrhea might be controlled through vaccination. Serotype-specific immunity may play a role in protection from disease. Tetravalent rhesus-human reassortant rotavirus vaccine (RRV-TV) (which contains a rhesus rotavirus with serotype G3 specificity and reassortant rhesus-human rotaviruses with G1, G2, and G4 specificity) provides coverage against the four common serotypes of human rotavirus. In clinical trials in industrialized countries, RRV-TV conferred 49% to 68% protection against any rotavirus diarrhea and 61% to 100% protection against severe disease. This vaccine was licensed by the U.S. Food and Drug Administration on August 31, 1998, and should be cost-effective in reducing diarrheal diseases in industrialized countries. The vaccine&

Rotavirus Spike Protein VP4 Is Present at the Plasma Membrane and Is Associated with Microtubules in Infected Cells | Journal...
VP4 is an unglycosylated protein of the outer layer of the capsid of rotavirus. It forms spikes that project from the outer layer of mature virions, which is mainly constituted by glycoprotein VP7. VP4 has been implicated in several important functions, such as cell attachment, penetration, hemagglutination, neutralization, virulence, and host range. Previous studies indicated that VP4 is located in the space between the periphery of the viroplasm and the outside of the endoplasmic reticulum in rotavirus-infected cells. Confocal microscopy of infected MA104 monolayers, immunostained with specific monoclonal antibodies, revealed that a significant fraction of VP4 was present at the plasma membrane early after infection. Another fraction of VP4 is cytoplasmic and colocalizes with β-tubulin. Flow cytometry analysis confirmed that at the early stage of viral infection, VP4 was present on the plasma membrane and that its N-terminal region, the VP8* subunit, was accessible to antibodies. Biotin ...

Seasonality of rotavirus infection. We examined the seasonal patterns of disease by plotting the monthly detection of rotavirus in the studies that provided detailed data on rotavirus hospitalization by month (Figure 2). The 10 studies that were identified spanned latitudes from 10° north to 35° south. In most countries, rotavirus was detected throughout the year. The only locations where rotavirus was not detected for 2 consecutive months were Juiz de Fora and Porto Alegre in Brazil. We examined the hypothesis that the seasonality of rotaviruses was distinct in countries located in temperate versus tropical climatic zones. The five studies from cities in the tropics (between 23.5° north and south of the equator) all had winter peaks not unlike the five studies from cities in the temperate zone. As expected, the winter peaks in the northern hemisphere occurred roughly between November and February, while the peaks in the southern hemisphere occurred between May and August.. DISCUSSION.

Vaccinate Your Baby : Rotavirus
Rotavirus is a contagious disease caused by any one of three strains of rotavirus. Children who get infected may have severe diarrhea, often with vomiting, fever, and stomach pain. They can become severely dehydrated (loss of body fluids) and need to be hospitalized and can even die.. Infants and young children are most likely to get rotavirus; however, older children and adults can also get the disease. Among U.S. children, those at highest risk of getting the disease include those in child care centers or other settings with many young children. The most severe rotavirus disease occurs in unvaccinated children between 3-35 months old. Older adults and adults with certain risk factors are also at higher risk of getting rotavirus disease.. Rotavirus is easily spread. The virus is in the feces of infected people, and it can be spread by hands, diapers, toys, changing tables, or doorknobs that have a small amount of feces on them. Rotavirus can live on objects for several days unless it is killed ...

Knowledge of rotavirus epidemiology is necessary to make informed decisions about vaccine introduction and to evaluate vaccine impact. During April 2010-March 2012, rotavirus surveillance was conducted among 9,745 children <5 years of age in 14 hospitals/health centers in Niger, where rotavirus vaccine has not been introduced. Study participants had acute watery diarrhea and moderate to severe dehydration, and 20% of the children were enrolled in a nutrition program. Of the 9,745 children, 30.6% were rotavirus positive. Genotyping of a subset of positive samples showed a variety of genotypes during the first year, although G2P predominated. G12 genotypes, including G12P, which has emerged as a predominant strain in western Africa, represented >80% of isolates during the second year. Hospitalization and death rates and severe dehydration among rotavirus case-patients did not differ during the 2 years. The emergence of G12P warrants close attention to the characteristics of
Rotavirus - Indiana Immunization Coalition
tab] [tab_item title=About Rotovirus] Rotavirus is a contagious virus that can cause gastroenteritis (inflammation of the stomach and intestines). Symptoms include severe watery diarrhea, often with vomiting, fever, and abdominal pain. Infants and young children are most likely to get rotavirus disease. They can become severely dehydrated and need to be hospitalized and can even die. Rotavirus was the leading cause of severe diarrhea among infants and young children in the United States before rotavirus vaccine was introduced in 2006. Prior to the vaccine, almost all U.S. children were infected with rotavirus before their 5th birthday. Globally, rotavirus is still the leading cause of severe diarrhea in infants and young children. In 2008, rotavirus caused an estimated 453,000 deaths worldwide in children younger than 5 years of age.. [/tab_item] [tab_item title=Information for Patients ...
Rotavirus Advocacy Activities | Sabin
Each year, rotavirus kills more than 200,000 children and hospitalizes millions more. Rotavirus is the most common cause of diarrheal hospitalizations and deaths among children worldwide.

N2 - Reassortants between serotype 3 SA11 and serotype 6 NCDV rotaviruses were used to determine the relative amounts of serum-neutralizing antibody to VP4 and VP7 of serotype 3 SA11 rotavirus in children after natural rotavirus exposure. Sera from Ecuadorian children of a population-based study and sera from children of a hospital-based study in Germany (excluding diarrhea patients) demonstrated high titers of VP7-specific but only low titers of VP4-specific antibodies. In contrast, paired sera from German children hospitalized with a symptomatic primary rotavirus gastroenteritis demonstrated a titer increase to VP4 more frequently than to VP7 protein by neutralization test and immunoblotting. For these rotavirus patients, we provided, previously, direct evidence ...
The American Academy of Pediatrics (AAP) now recommends a rotavirus vaccine be included in the lineup of routine immunizations given to all infants.. The RotaTeq vaccine has been found to prevent approximately 75% of cases of rotavirus infection and 98% of severe cases. Another vaccine, Rotarix, also is available and is effective in preventing rotavirus infection. Your doctor will have the most current information about these vaccines.. A previous rotavirus vaccine was taken off the market in 1999 because it was linked to an increased risk for intussusception, a type of bowel obstruction, in young infants. Neither RotaTeq nor Rotarix have been found to have this increased risk.. Washing hands well and often is the best way to limit the spread of rotavirus infection. Kids who are infected should stay home from childcare groups until their diarrhea has ended. In hospitals, rotavirus outbreaks are controlled by isolating infected patients and following strict hand-washing procedures.. ...
Crystallisation and preliminary X-ray diffraction analysis of the carbohydrate-recognizing domain (VP8*) of bovine rotavirus...
Infectivity of rotavirus is dramatically enhanced by proteolytic cleavage of its outer layer VP4 spike protein into two function domains, VP8* and VP5*. The carbohydrate-recognising domain VP8* is proposed to bind sialic acid-containing host cell-surface glycans, followed by a series of subsequent virus-cell interactions. Live attenuated human and bovine rotavirus vaccine candidates to prevent gastroenteritis have been derived from bovine rotavirus strain NCDV. The NCDV VP8*64-224 was over-expressed, purified to homogeneity and crystallized in the presence of a N-acetylneuraminic acid derivative. X-ray diffraction data were collected to a resolution of 2.0 Šand the crystallographic structure of NCDV VP8*64-224 determined by molecular replacement ...

Sustained Decrease in Laboratory Detection of Rotavirus after Implementation of Routine Vaccination - United States, 2000-2014
Negar Aliabadi, MD1,2, Jacqueline E. Tate, PhD2, Amber K. Haynes, MPH2, and Umesh D. Parashar, MD2 (Author affiliations at end of text). Rotavirus infection is the leading cause of severe gastroenteritis among infants and young children worldwide (1,2). Before the introduction of rotavirus vaccine in the United States in 2006, rotavirus infection caused significant morbidity among U.S. children, with an estimated 55,000-70,000 hospitalizations and 410,000 clinic visits annually (3). The disease showed a characteristic winter-spring seasonality and geographic pattern, with annual seasonal activity beginning in the West during December-January, extending across the country, and ending in the Northeast during April-May (4). To characterize changes in rotavirus disease trends and seasonality following introduction of rotavirus vaccines in the United States, CDC compared data from CDCs National Respiratory and Enteric Virus Surveillance System (NREVSS), a passive laboratory reporting system, for ...
Decline in severe diarrhea hospitalizations after the introduction of rotavirus vaccination in Ghana: a prevalence study | BMC...
Almost all diarrhea deaths in young children occur in developing countries. Immunization against rotavirus, the leading cause of childhood severe dehydrating acute diarrhea may reduce the burden of severe diarrhea in developing countries. Ghana introduced rotavirus and pneumococcal vaccination in the national expanded program on immunization in May 2012. Review of all-cause diarrheal hospitalization data for children aged 59 months and younger at 2 pediatric referral hospitals in southern Ghana from 2008 to 2014. The proportion of acute diarrhea (defined as 3 or more watery, non-bloody stools within 24 hours that has lasted for less than 7 days) cases caused by rotavirus was determined. Temporal trend and age group distribution of all-cause diarrhea and rotavirus gastroenteritis before and after introduction of the new vaccines were compared. Of the 5847 children hospitalized with all-cause diarrhea during the 74 months (January 2008 - February 2014), 3963 (67.8%) children were recruited for rotavirus

The Structure of the Rotavirus Inner Capsid Studied by Electron Microscopy of Chemically Disrupted Particles | Microbiology...
Summary The inner capsid structure of the OSU strain of porcine rotavirus was studied by electron microscopy of freeze-dried preparations and of negatively stained chemically disrupted virus particles. The analysis of the particles by the freeze-drying technique revealed a T:13 l (laevo) symmetry for the organization of the inner capsid. Treatment of single-capsid rotavirus particles with 30% formamide or 5 m-urea resulted in their degradation, giving rise to very similar products, corresponding to isolated vertices, edges and faces of the virus icosahedron. An analysis of such structures confirmed the triangulation number and handedness of the rotavirus inner capsid, and provided evidence for the open-mesh model, in which the five- and six-coordinated axes are represented by holes formed by smaller trimeric morphological subunits.

Number of Children with Diarrhea Drops Dramatically with Rotavirus Vaccine - Rostropovich Vishnevskaya Foundation
Unless babies are vaccinated, almost all of them get rotavirus, the doctor told me. Having the vaccine available for free in Gaza can save babies and parents from so much suffering... - Majdoolin, first-time mother, Gaza City. The rotavirus vaccine, which RVF worked with the Palestinian Ministry of Health (MOH) to introduce in 2016, is already having a huge impact on young children in the West Bank and Gaza. In Gaza, there has already been a 28% reduction in rates of children aged three years and under hospitalized for diarrhea. In the West Bank, there are over a third fewer cases of severe diarrhea in children under five.. Rotavirus disease, which causes severe diarrhea, is a killer of infants and young children throughout the world. Vaccination is the most effective way to prevent rotavirus infection. All Palestinian babies now receive this life-saving vaccine. To date, nearly 400,000 infants have been fully immunized with coverage rates over 95%.. RVF expects rates of severe diarrhea in ...

Whole-genome, sequence-independent amplification and 454 pyrosequencing of a rotavirus SA11 cell culture sample with an unknown passage history yielded consensus sequences of twelve complete genome segments. Two distinct sequences for genome segment 8 (encoding NSP2) were present, indicating a mixed infection with two rotavirus SA11 strains. The genotypes of the viruses were G3-P-I2-R2-C5-M5-A5-Nx-T5-E2-H5, where x was either 5 or 2. The strains were named RVA/ Simian-tc/ZAF/SA11-N5/1958/G3P and RVA/Simiantc/ ZAF/SA11-N2/1958/G3P. The genotype (N2) and sequence of genome segment 8 of RVA/Simian-tc/ZAF/ SA11-N2/1958/G3P were identical to that of the bovine rotavirus O agent. Five novel amino acids were detected in minor population variants of three genome segments. Genome segment 1 (VP1) has a high nucleotide substitution rate, but the substitutions are synonymous. Distance matrices and Bayesian molecular clock phylogenetics showed that SA11-N2 is a reassortant containing genome ...
Rotavirus vaccine: fingers crossed | The Pump Handle
by revere, cross-posted at Effect Measure. Earaches, respiratory infections and diarrhea are the bane of existence for young parents. All are potentially the result of contagious agents. The most common agent for diarrhea in infants and children is rotavirus, a double-stranded DNA virus, that CDC estimates causes 400,000 doctor visits, 200,000 emergency room visits and 55.000 to 70,000 hospitalizations each year in the under 5 year old age group. Infection produces significant immunity, and while there are seven different serotypes (A through G), 90% of infections are serotype A. In addition to diarrhea, rotavirus infections cause nausea, vomiting and fever, often with dehydration that can be fatal to an infant. By the time a child turns five, he or she is likely to have had a rotavirus infection. So this virus causes a lot of sickness and even more dollars. A recent estimate is that each hospitalization costs about $3600.. If rotavirus infection could be prevented by a vaccine it would have a ...
Rotavirus Vaccination Via Oral Thin Film Delivery | Changemakers
The advantages of convenience and room temperature stability associated with our quick dissolving thin film delivery system can be broadly used. The thin film system is applicable to all oral vaccines and oral protein based therapeutic drugs, as well as biopharmaceuticals that can be converted to the oral route. The impact on vaccines could be transformational for infectious diseases such as shigellosis and rotaviral gastroenteritis which combined cause over 1 million deaths in children every year in the developing world. Considering rotavirus alone, the demand for any vaccine will likely be high since all children by the age of five will have been infected by rotavirus and many children in third world countries will die. Currently, it is recommended that all new born infants in the U.S. be given rotavirus vaccine and it is highly likely that most of the world will follow this recommendation. It is estimated that the required annual worldwide rotavirus vaccine doses will be greater than 400 ...
Prevalence and diversity of rotavirus A genotypes cirulating in Turkey during a 2-year sentinel surveillance period, 2014-2016 ...
Human rotavirus A (RVA) is the main etiological agent of watery diarrhea among children under 5 years of age worldwide. The aims of this study were to investigate the prevalence and diversity of RVA genotypes circulating in Turkey during a 2-year sentinel surveillance study. A total of 1639 rotavirus antigen-positive stool samples were obtained from children younger than 5 years of age hospitalized with acute gastroenteritis. Rotavirus G and P genotypes were determined by reverse transcription polymerase chain reaction (RT-PCR) with consensus primers for the VP7 and VP4 genes, followed by semi-nested type-specific multiplex PCR. Rotavirus RNA was detected in 1396 (85.3%) of the samples tested. The highest detection rate (38.2%) was obtained among children in the 0-12 months age group, followed by children in the 13-24 months age group (36.2%). The most prevalent genotype was G1P (24.6%) followed by G3P (19.6%), G9P (12.2%), G2P (9.5%), G2P (6.5%), and G4P (4.8%). The ...

In-season and out-of-season variation of rotavirus genotype distribution and age of infection across 12 European countries...
The EuroRotaNet surveillance network has conducted rotavirus genotype surveillance since 2007 in 16 European countries. Using epidemiological and microbiological data from 39,786 genotyped rotavirus-positive specimens collected between September 2007 and August 2013, we assessed genotype distribution and age distribution of rotavirus gastroenteritis (RVGE) cases in and out of peak season in 12 countries which were yet to implement routine rotavirus vaccination. In multinomial multivariate logistic regression, adjusting for year, country and age, the odds of infection caused by genotype-constellation 2 DS-1-like stains (adjusted multinomial odds ratio (aM-OR) = 1.25; 95% confidence interval (CI): 1.13-1.37; p ...
Rotavirus rebound among infants prompts gastro warning | Australian Doctor
A resurgence in rotavirus gastro cases among infants has prompted warnings from health authorities about the importance of hand hygiene and vaccination.. South Australian communicable disease experts have sounded the alarm after the number of rotavirus cases among infants more than doubled from 299 in 2016 to 658 so far in 2017.. Infants accounted for 60% of all rotavirus notifications, with total numbers across all age groups increasing almost threefold from 447 to 1255 in the last year.. SA Healths Chief Medical Officer Professor Paddy Phillips says the increase in rotavirus among infants is worrying but preventable with good hand hygiene and vaccination.. Following good hand hygiene, cleaning bathroom taps and toilets with diluted bleach, disposing of infants nappies immediately, and safely washing childrens toys helps to significantly prevent the spread of the disease, he said in a statement.. A rise in rotavirus cases is being seen in other states, according to Dr Louise Flood, Acting ...
Folding and retention of rotavirus glycoproteins in the endoplasmic reticulum
The endoplasmic reticulum (ER) is a membrane bound organelle composed of a network of cisternae stretching throughout the cytoplasm. Functionally, the ER performs many essential processes, such as glycosylation, and biosynthesis of lipids; it provides a redox potential condition for forming S-S linkages, and a quality control system, and functions as an intracellular calcium store. Rotavirus, a segmented dsRNA virus, is one of very few viruses that undergoes a unique maturation process in the ER and has therefore been an attractive model for the study of ER-translocation, retention and protein folding. In this thesis, I have studied how rotavirus and rotavirus proteins assemble in the eucaryotic cells. The rotavirus genome encodes 12 structural and nonstructural proteins; two of these proteins, the outer capsid VP7 protein and the nonstructural enterotoxin NSP4 protein, are associated with the ER and have been of particular interest in this thesis. We found that brefeldin A, a compound that ...
Daily dose for kids: A New Indian Vaccine for Rotavirus enters final stage of trials
Comment: This is interesting news, since the Bharat Biotech vaccine for Rotavirus (116 E) made in India has already undergone the necessary testing & is likely to be launched in the next couple of months (possibly Jan 2015). Among all the newer vaccines, rotavirus is the only one where we have large amount of Indian data available regarding the disease from India through the IRSN - Indian Rotavirus Surveillance Network. This is probably one of the reasons why we are getting India specific vaccines for this disease. It is important to start vaccinating children early against this disease so as to prevent significant disease burden, since almost EVERY child will suffer from Rotavirus diarrhea if they are not vaccinated, probably by the age of 2 years. ...
A to Z: Rotavirus
In the United States, rotavirus infection outbreaks are common during the winter and spring months. Outbreaks are particularly problematic in childcare centers and childrens hospitals because the infection spreads so easily.. Rotavirus symptoms can last from 3-8 days and include fever, nausea, vomiting, abdominal cramps, and frequent, watery diarrhea. A cough and runny nose may also occur. Some rotavirus infections cause few or no symptoms at all, especially in adults.. The diarrhea from a rotavirus infection can be so severe that it quickly leads to dehydration, especially in infants and young children. If dehydration is severe, intravenous (IV) fluids given in the hospital can bring the bodys fluid and salt levels back to normal.. ...

Outer capsid protein VP4 - Rotavirus A (strain RVA/Human/United States/D/1974/G1P1A) (RV-A)
Spike-forming protein that mediates virion attachment to the host epithelial cell receptors and plays a major role in cell penetration, determination of host range restriction and virulence. Rotavirus entry into the host cell probably involves multiple sequential contacts between the outer capsid proteins VP4 and VP7, and the cell receptors. According to the considered strain, VP4 seems to essentially target sialic acid and/or the integrin heterodimer ITGA2/ITGB1 (By similarity).
Critical role of cellular cholesterol in bovine rotavirus infection | Virology Journal | Full Text
Bovine rotavirus (BRV) is a non-enveloped dsRNA virus that cause neonatal calf diarrhea. Lipid rafts are cholesterol-enrich membrane mircodomains that play a vital role in many cellular processes. In this study, the effect of cellular cholesterol depletion on infection of MA-104 cells with bovine rotavirus was investigated. We demonstrated that cholesterol depletion of the plasma membrane by MβCD had no effect on BRV binding to cells but significantly impaired BRV entry in a dose-dependent manner and the effect was partially reversed by addition of exogenous cholesterol, suggesting the reduction of BRV infection by MβCD was specifically due to cholesterol depletion. Cholesterol depletion after virus entry did not reduce BRV replication, whereas affected virus assembly. Taken together, our results demonstrate that cell membrane cholesterol is essential to BRV infectivity.

Exploration of the Biologic Basis for Underperformance of Oral Polio and Rotavirus Vaccines in Bangladesh - Full Text View -...
Oral polio and rotavirus vaccines are significantly less effective in children living in the developing world. Tropical enteropathy, which is associated with intestinal inflammation, decreased absorption and increased permeability, may contribute substantially to oral vaccine failure in developing country settings. Other possible causes of oral vaccine underperformance include malnutrition, interference with maternal or breastmilk antibodies, changes in gut microbiota, and genetic susceptibility.. Primary Objective: to determine whether tropical enteropathy impairs the efficacy of oral polio and rotavirus vaccines in children in Bangladesh.. Secondary Objectives: 1) to determine the impact of an inactivated polio vaccine (IPV) boost on the efficacy of oral polio vaccine and 2) to determine the efficacy of oral rotavirus vaccine to prevent rotavirus diarrhea. The polio and rotavirus randomized clinical trials are embedded as secondary objectives within the exploratory study of tropical ...
Impact of Rotavirus Vaccination on Hospital-Acquired Rotavirus Gastroenteritis in Children | Articles | Pediatrics
Results: A similar dramatic decline (,60% compared with the median of previous seasons) occurred in the rates of cases of both CA (P , .0001) rotavirus hospitalizations and HA (P , .01) rotavirus infections in the 2007-2008 season compared with previous seasons, whereas the rates of CA and HA influenza and respiratory syncytial virus, respectively, remained stable. Improvements in hand-hygiene compliance did not correlate with a reduction in the transmission rate of rotavirus in the hospital. Both CA and HA rotavirus rates remained much lower in the 2008 -2009 than in the 2003-2007 seasons. ...
The American Journal of Tropical Medicine and Hygiene | The Emergence of Rotavirus G12 and the Prevalence of Enteric Viruses in...
Abstract. Diarrhea is a major cause of childhood morbidity and mortality in developing countries, and the majority of infections are of viral etiology. We aimed to compare the etiological prevalence of the major enteric viruses in an urban and a rural setting in southern Vietnam. We simultaneously screened fecal specimens from 362 children in Ho Chi Minh City and Dong Thap province that were hospitalized with acute diarrhea over a 1-month-long period for four viral gastrointestinal pathogens. Rotavirus was the most common pathogen identified, but there was a differential prevalence of rotavirus and norovirus between the urban and rural locations. Furthermore, rotavirus genotyping and phylogenetic analysis again differentiated the genotypes by the sampling location. Our data show a disproportional distribution of enteric viral pathogens in urban and rural locations, and we provide evidence of continual importation of new rotavirus strains into southern Vietnam and report the emergence of rotavirus

Outer capsid protein VP4 - Human rotavirus A
Outer capsid protein VP4: Spike-forming protein that mediates virion attachment to the host epithelial cell receptors and plays a major role in cell penetration, determination of host range restriction and virulence. Rotavirus attachment and entry into the host cell probably involves multiple sequential contacts between the outer capsid proteins VP4 and VP7, and the cell receptors. It is subsequently lost, together with VP7, following virus entry into the host cell. Following entry into the host cell, low intracellular or intravesicular Ca(2+) concentration probably causes the calcium-stabilized VP7 trimers to dissociate from the virion. This step is probably necessary for the membrane-disrupting entry step and the release of VP4, which is locked onto the virion by VP7.

Thirty-six deaths reported in Swaziland rotavirus outbreak - Outbreak News Today
In an announcement by Prime Minister Sibusiso Dlamini, 3,042 cases of diarrhea due to rotavirus were treated in outpatient departments of hospitals countrywide. More than 500 children affected required hospitalization for their illness.. Dlamini assured the public that all treatment requirements for the management of the disease have been distributed to all facilities and health workers have been refreshed on case management and treatment guidelines. According to the US Centers for Disease Control and Prevention (CDC), rotavirus disease is most common in infants and young children, but adults and older children can also become infected with rotavirus. It is responsible for the death of over 600,000 children annually worldwide. Once a person has been exposed to rotavirus, it takes about 2 days for symptoms to appear.. Rotavirus is shed (passed from a persons body into the environment) in feces (stool) of infected persons. The virus spreads by the fecal-oral route; this means that the virus must ...
Rotavirus Vaccine will Improve Child Survival by More than Just Preventing Diarrhea: Evidence from Bangladesh | The American...
Abstract. Despite the high burden of rotavirus diarrhea, uptake of rotavirus vaccines in Asia remains low. This primarily stems from a perception of rotavirus as a non-life-threatening pathogen amidst a background of competing health priorities and limited resources. In the largest pediatric hospital of Bangladesh, where there is a fierce competition for beds, we found that between November 2015 and October 2016, 12% of 23,064 admissions were due to gastrointestinal infections, 54% of which were caused by rotavirus. One in four cases requiring hospitalization, or 5,879 cases, was refused because of unavailability of beds. Most refused cases were of pneumonia (22%), severe perinatal asphyxia (17%), preterm birth complications (7%), and meningitis (2%), all of which bear high risks of death or disability, if not treated timely. When determining vaccine policies and conducting vaccine impact studies, it would be shortsighted to not consider the impact on morbidity and mortality of cases that are refused
Coadministration of Measles-rubella and Rotavirus Vaccines - Full Text View - ClinicalTrials.gov
The investigators aim to establish the non-inferiority of concomitant administration of measles-rubella and rotavirus vaccines to measles-rubella vaccine given alone in terms of measles seroconversion rates. The primary study hypothesis is the measles seroconversion rate as defined by the percentage of children seroconverting to measles with a measles serum antibody concentration of ,=1:120 at 8 weeks post vaccination after the concomitant administration of measles-rubella and rotavirus vaccines is non-inferior to that obtained when measles-rubella vaccine is given alone in children 9 months of age who have received a primary rotavirus vaccine series with the first dose between 6 and 10 weeks and the second at least 4 weeks later and are seronegative for measles antibody in the pre-vaccination sample ...

Nlrp9b inflammasome restricts rotavirus infection in intestinal epithelial cells
Rotavirus, a leading cause of severe gastroenteritis and diarrhoea in young children, accounts for around 215,000 deaths annually worldwide. Rotavirus specifically infects the intestinal epithelial cells in the host small intestine and has evolved strategies to antagonize interferon and NF-κB signalling, raising the question as to whether other host factors ... read more participate in antiviral responses in intestinal mucosa. The mechanism by which enteric viruses are sensed and restricted in vivo, especially by NOD-like receptor (NLR) inflammasomes, is largely unknown. Here we uncover and mechanistically characterize the NLR Nlrp9b that is specifically expressed in intestinal epithelial cells and restricts rotavirus infection. Our data show that, via RNA helicase Dhx9, Nlrp9b recognizes short double-stranded RNA stretches and forms inflammasome complexes with the adaptor proteins Asc and caspase-1 to promote the maturation of interleukin (Il)-18 and gasdermin D (Gsdmd)-induced pyroptosis. ...
Rotavirus infection in adults
Rotavirus has been recognised for 30 years as the most common cause of infectious gastroenteritis in infants and young children. By contrast, the role of rotavirus as a pathogen in adults has long been underappreciated. Spread by faecal-oral transmission, rotavirus infection in adults typically mani …
Rotavirus Vaccines and Health Care Utilization for Diarrhea in the United States (2007-2011) | American Academy of Pediatrics
We observed declines in rates of diarrhea-associated hospitalizations, emergency department visits, and outpatient visits in US children ,5 years of age over four successive rotavirus seasons following implementation of rotavirus vaccination, with greater declines in later years when greater vaccine coverage had been achieved and during months of the year with peak rotavirus activity. Both RV5 and RV1 were highly effective in preventing rotavirus-coded hospitalizations and also prevented diarrhea-associated hospitalizations and emergency department visits; both vaccines conferred similar protection. The protection from RV5 vaccination against rotavirus-coded hospitalizations was sustained at a high level through four years of life, with no indication of waning immunity. The reduction in rotavirus-coded hospitalization rates among unvaccinated children in postvaccine years compared with prevaccine years indicates indirect benefits from vaccination; the magnitude of indirect benefit varied over ...

Prevalence of Groups A and C Rotavirus Antibodies in Infants with Biliary Atresia and Cholestatic Controls | IRIS Univ. Cagliari
OBJECTIVE: To analyze the prevalence of acute asymptomatic group A and C rotavirus (RV-A and RV-C) infection in neonates with cholestasis. STUDY DESIGN: Participants were infants ,180 days of age with cholestasis (serum direct or conjugated bilirubin ,20% of total and ≥2 mg/dL) enrolled in the Childhood Liver Disease Research and Education Network during RV season (December-May). Forty infants with biliary atresia (BA), age 62 ± 29 days (range, 4.7-13 weeks) and 38 infants with cholestasis, age 67 ± 44 days (range, 3-15.8 weeks) were enrolled. RESULTS: At enrollment, RV-A IgM positivity rates did not differ between infants with BA (10%) vs those without (18%) (P = .349). RV-C IgM was positive in 0% of infants with BA vs 3% in those without BA (P = .49). RV-A IgG was lower in infants with BA: 51 ± 39 vs 56 ± 44 enzyme-linked immunoassay unit, P = .045 but this difference may lack biological relevance as maternal RV-A IgG titers were similar between groups. Infant RV-A IgM titers at 2-6 ...

NO Donors / Precursors - mTOR inhibitors suppress homologous recombination repair
Immunoglobulin A (IgA) may be the major defense response induced in the intestine by rotavirus disease, but vaccination with virus-like contaminants induces IgG predominantly, not IgA. both serum IgG and IgA and fecal IgA. Both IgA normal and IgA knockout mice were protected from rotavirus challenge at 42 times totally. Ten months carrying out a major disease, both IgA regular and knockout mice still got high degrees of serum and fecal antirotavirus antibody and had been totally shielded from rotavirus problem. To see whether compensatory mechanisms apart from IgG had been responsible for safety from rotavirus disease in IgA knockout mice, mice had been depleted of Compact disc4+ T cells or Compact disc8+ T cells. Zero noticeable adjustments in the amount of safety had been observed in depleted NXY-059 mice. These data display that fecal or systemic IgA isnt essential for safety from rotavirus disease and claim that in the PTPRR lack of IgA, IgG may play a substantial part in safety from ...
Rotavirus vaccine coming in 2013
The Department of Health has announced that rotavirus vaccine will be added to the childhood vaccination programme with effect from September 2013.. Rotavirus is reported as causing approximately 140,000 cases of diarrhoea per year in the children under 5 years old. Of these some 14,000 cases result in a hospital admission. It is expected that the introduction of this vaccine will reduce hospital admissions by up to 70%. The vaccine is a live oral vaccine and two doses are recommended.. The JCVI statement recommending the vaccine provides further analysis and detail. Action: Clinicians involved in the delivery of the child immunisations should be aware of this change.

To the Editor: Viral gastroenteritis is caused by many pathogens, each with unique characteristics requiring different laboratory test for identification1,2. In our country several groups emphasizes the role of the viral gastroenteritis in children3-4. Similar studies have been done in the european countries5-7, Asia8, America9 and Oceania10. In relation to these contributions and since we are geographically related and have a similar context we could like to point out three aspects: first, to bring forward or 16 years of experience in systematic detection of Rotavirus in children; second, to show our findings in detecting other virus causing gastroenteritis (Adenovirus and Astrovirus) and finally, to mark that both Rotavirus infection and that caused by the aforementioned virus are reported to National Epidemiological Surveillance System. Since 1986 we systematically search for Rotavirus in fecal samples from children under seven years. At that time Rotavirus antigen detection by means of a ...
CDC Foundation Receives Three Grants Totaling $13.5 Million For Meningitis and Rotavirus Global Advancements | CDC Foundation
The CDC Foundation has received three grants totaling $13.5 million from the Bill & Melinda Gates Foundation to improve the lives of millions worldwide. The grants will enable the National Center for Immunization and Respiratory Diseases of the U.S. Centers for Disease Control and Prevention (CDC) to work in collaboration with partners to advance the implementation of meningitis and rotavirus vaccines, ensuring global disease protection. Meningococcal meningitis and rotavirus gastroenteritis are deadly diseases but are increasingly preventable now that immunization initiatives in the African meningitis belt and other resource-poor areas are reaching the most vulnerable populations, said Dr. Anne Schuchat, the director of CDCs National Center for Immunization and Respiratory Diseases. The Gates Foundation funding will allow CDC to work together with countries and international partners to assure that a strong science base is available to sustain prevention efforts.

AVIAN ROTAVIRUSES by CURTIS RAYMOND BARTZ
The prevalence of antirotavirus antibodies in chickens and turkeys in the Gonzales, Texas and Llano, Texas areas was studied. Caged layer chicken flocks were found to have a prevalence of 64% when samples were taken randomly. This compares to 45% in chicken broiler breeder flocks and 92% in turkey breeding flocks. The natural occurrence of turkey rotavirus infection in two separate field studies showed an increase in mortality varying from 9% to 45% above expected death losses. Clinically, pasted vents, lacitude, and general malaise were noted in affected poults. Lesions noted on post mortem examination were; slight ballooning of the small intestine, excessively large ceca, and mild hyperemia of the small and large intestines. The use of maternal antibody from simian rotavirus immunized chickens eggs for preventing murine rotavirus infection in infant mice was investigated. There was a reduction from 91% to 15% incidence when infant mice were treated twice daily with egg yolk immunoglobulin. The need

Results show that S boulardii diminished the time of diarrhoea by 31.4% and shortened time with fever by 73% (table 3). Children receiving the multiple species product tended to have less time with diarrhoea and no patients vomited after the treatment was started. In previous studies that administered multiple species products similar to the one we used, other authors found a rather more pronounced effect, 30 hours [14, 19] and 30-36 hours reduction in diarrhoeal duration [20-23], in comparison with the 26 hours reduction we found. Infants hospitalized in our study were admitted with severe diarrhoea and had intense clinical manifestations in comparison to outpatients with rotavirus diarrhoea; this could explain the less intense results obtained. Although not significant, we consider relevant the trend to diminish time of diarrhoea in the group receiving the multiple probiotic products, because decreasing severity of diarrhoea may help reducing the nutritional impact of the diarrhoeal ...
Mutated G4P rotavirus associated with a nationwide outbreak of gastroenteritis in Nicaragua in 2005
During February and March 2005, one of the largest national recorded outbreaks of severe acute gastroenteritis occurred in Nicaragua, affecting ≥64,000 individuals and causing ≥56 deaths, predominantly in children under 5 years of age. Through a nationwide laboratory-based study, stool samples were collected and investigated for rotavirus. Of 108 stool samples examined, 72 (67%) were positive for rotavirus. While 69% (50/72) of the positive samples were found in children less than 2 years of age, 50% (6/12) of the adult samples were positive. A mutated G4P strain was the most commonly recognized strain (85%), followed by mixed G strains (8%) and G9P (7%) strains. Phylogenetic analysis of the VP7 gene revealed that the G4 strains belonged to the emerging lineage Ic and was distantly related to the ST3 and VA70 G4 strains. Secondary structure predictions of the VP7 G4 protein revealed an insert of an asparagine residue in position 76, which, combined with additional mutations, ...
Vaccines for the prevention of diarrhea due to cholera, shigella, ETEC and rotavirus | BMC Public Health | Full Text
Diarrhea is a leading cause of mortality in children under 5 years along with its long-term impact on growth and cognitive development. Despite advances in the understanding of diarrheal disorders and management strategies, globally nearly 750,000 children die annually as a consequence of diarrhea. We conducted a systematic review of the efficacy and effectiveness studies. We used a standardized abstraction and grading format and performed meta-analyses for all outcomes. The estimated effect of cholera, shigella, Enterotoxigenic Escherichia coli (ETEC) and rotavirus vaccines was determined by applying the standard Child Health Epidemiology Reference Group (CHERG) rules. A total of 24 papers were selected and analyzed for all the four vaccines. Based on the evidence, we propose a 74% mortality reduction in rotavirus specific mortality, 52% reduction in cholera incidence due to their respective vaccines. We did not find sufficient evidence and a suitable outcome to project mortality reductions for cholera
Vaccines CAUSE Pneumonia! - Vaccine Awareness
The Rotavirus vaccine - an American vaccine against childhood diarrhea and dehydration - has been found to cause pneumonia!. It has already been withdrawn once for causing intersuption of the bowel (where the bowel sticks together - the condition can be life threatening if not treated).. Now the FDA have said that according to 11 trials, rotavirus vaccine causes pneumonia, bronchitis, convulsions and death.. 63,000 children were given the vaccine and there was a statistically significant increase in the number of pneumonia deaths compared with the placebo, and the rotavirus vaccine group also had more bronchitis and a higher rate of convulsions.. The FDA now want to bring in an oral rotavirus vaccine instead of using the injection.. Source: Reuters, 15 February 2008.. ...

In this study we have compared two commercially produced assays, an ELISA (Rotazyme, Abbott) and a newly developed assay--solid phase aggregation of coupled erythrocytes (SPACE) (Wellcome Research Laboratories), with electron microscopy (EM). The SPACE test appeared less sensitive than EM. The ELISA was shown to be as sensitive as EM but more versatile. Our experience suggests that the ELISA could be successfully incorporated into the routine of any diagnostic laboratory.. ...

Emergence of Serotype G12 Rotaviruses, Hungary
We describe the emergence of serotype G12 rotaviruses (67 [6.9%] of 971 specimens tested) among children hospitalized with rotavirus gastroenteritis in Hungary during 2005. These findings are consistent with recent reports of the possible global spread and increasing epidemiologic importance of these strains, which may have implications for current rotavirus vaccination strategies.
Characterization of a Membrane Calcium Pathway Induced by Rotavirus Infection in Cultured Cells | Journal of Virology
We have previously reported that during the course of rotavirus infection of MA104 cells, there was a progressive increase in membrane permeability to molecules of increasing size. At early times after initiation of viral protein synthesis (4 to 6 h postinfection), permeability to monovalent cations such as Na+ and K+, as well as Ca2+, increased. Later, after 8 h postinfection, molecules which are normally impermeative in an uninfected cell, such as ethidium bromide and trypan blue, entered (17, 18).. The permeability pathway for Ca2+ in infected cells was studied by using step changes of extracellular Ca2+ concentration. Studies using fluorescent indicators have shown that the initial transient increase in [Ca2+]i following the extracellular Ca2+ change reflects the influx of Ca2+ from the external compartment (31). The fast increase in [Ca2+]i in response to Ca2+addition appeared to be directly related to the influx pathway, since it varied with the driving force for Ca2+ entry. The elevation ...
