Isolation of animal viruses from farm livestock waste, soil and water. (1/337)

Ten porcine enteroviruses, 2 porcine adenoviruses and 1 coronavirus were isolated directly from 32 samples of slurry collected from a pig fattening house. Concentration of the same samples by adsorption with the polyelectrolyte PE-60 yielded 24 porcine enteroviruses and 3 porcine adenoviruses. A porcine enterovirus was isolated, following PE-60 concentration, from 1 to 6 slurry samples from a sow farrowing house. No virus was isolated from 12 samples of slurry from dairy cows nor from 6 slurry samples from a calf-rearing unit. A porcine enterovirus was isolated from soil samples, after concentration with PE-60, collected 1, 2 and 8 days after pig slurry was spread on hay stubble. Two porcine enteroviruses were isolated by membrane filtration from 26 samples of surface run-off from land on which pig slurry was routinely spread, and 2 bovine enteroviruses were isolated from cattle feedlot run-off after adsorption to layers of talc and celite followed by hydroextraction. A porcine enterovirus was also isolated from 1 of 33 samples of surface water collected on farms on which pig slurry was routinely spread on the land, but no virus was isolated from 36 samples of ground water from the same farms. The surface water and ground water samples were concentrated by talc-celite adsorption and hydroextraction.  (+info)

A novel internal open reading frame product expressed from a polycistronic mRNA of porcine epidemic diarrhoea virus may not contribute to virus attenuation. (2/337)

Cell-culture-adapted (ca) porcine epidemic diarrhoea virus (PEDV) contains three internal open reading frames (I ORF) within the nucleocapsid protein gene and lacks the downstream counterpart of porcine transmissible gastroenteritis virus ORF7 or feline infectious peritonitis virus ORF6a. To confirm whether such features also exist in wild-type (wt) PEDV, the 3' 1800 nucleotides of its genome were sequenced and were found to be identical to those of ca virus. The coding potential of I-1 ORF was ascertained by transient expression in Vero cells followed by immunofluorescence using antipeptide sera. The I-1 protein was synthesized as a 12 kDa non-phosphorylated PEDV-specific protein that was not present in detectable amounts in virions. However, a low copy number of I-1 in the virion would suggest it is a structural component. Nevertheless, identical nucleotide sequences and gene expression strategies of attenuated ca virus and its virulent parent, wt PEDV, demonstrate that the 3' 1800 nucleotides or the genes and gene products encoded therein may not contribute to virus attenuation.  (+info)

In situ hybridization for the detection and localization of porcine epidemic diarrhea virus in the intestinal tissues from naturally infected piglets. (3/337)

Detection and localization of porcine epidemic diarrhea virus (PEDV) was studied by in situ hybridization with a nonradioactive digoxigenin-labeled probe in formalin-fixed, paraffin-embedded tissues from 10 naturally infected piglets. A 377-base pair cDNA probe for viral RNA encoding the membrane proteins of PEDV cell-culture-adapted strain V215/78 was generated by the reverse transcription polymerase chain reaction. In the retrospective study of pigs from herds with diarrhea, the 10 piglets naturally infected with PEDV had positive signals for PEDV by in situ hybridization. When intestinal tissues were hybridized with the PEDV probe, a strong signal was seen in the villus enterocytes of jejunum and ileum but not in the cecum and colon. Positive cells typically had dark brown reaction products in the cytoplasm. Scattered epithelial cells along the ileal Peyer's patches dome areas contained viral RNA. In one piglet, hybridization signal was also found in the duodenum. PEDV was not demonstrated in tissues outside of the intestinal tract. These findings indicate that jejunal and ileal villus enterocytes are the main target of PEDV replication during epizootic outbreaks of the disease.  (+info)

Detection of Australian gill-associated virus (GAV) and lymphoid organ virus (LOV) of Penaeus monodon by RT-nested PCR. (4/337)

A highly sensitive test based on reverse transcription followed by nested polymerase chain reaction (RT-nPCR) was developed to detect the Australian yellow-head-like viruses, gill-associated virus (GAV) and lymphoid organ virus (LOV) of Penaeus monodon. The RT-nPCR detected viral RNA in as little as 10 fg lymphoid organ total RNA isolated from GAV-infected P. monodon. Amplification of serial dilutions of a GAV cDNA clone showed that the nested PCR was sufficiently sensitive to detect a single genome equivalent using a DNA template. The specificity and sensitivity of the RT-nPCR was also demonstrated using experimentally infected P. (Marsupenaeus) japonicus, where GAV sequences could be amplified from lymphoid organ and haemocyte RNA as early as 6 h post infection (p.i.), and from gills by 24 h p.i. In contrast, transmission electron microscopy (TEM) identified nucleocapsids and virions in lymphoid organ cells and haemocytes from Days 3 and 6 p.i., respectively, while there was no evidence of infection in gill cells at any time. The practical application of the RT-nPCR was demonstrated by screening healthy wild-caught P. monodon broodstock. The high prevalence (>98%) of broodstock that were positive by RT-nPCR suggests that LOV is endemic in northern Queensland. In addition, results with lymphoid organ, gill and haemocyte RNA suggest that small gill biopsies may be best suited to the non-sacrificial testing of valuable broodstock. The speed and sensitivity of the RT-nPCR make it a useful adjunct to TEM for diagnosing LOV/GAV infection of P. monodon, with the additional benefit that screening of gill biopsies may facilitate selection of LOV-free broodstock.  (+info)

Acute undifferentiated neonatal diarrhea in beef calves. I. Occurence and distribution of infectious agents. (5/337)

Beef calves in a 48-cow herd were studied during one calving season from birth to ten days of age to determine the presence or absence of potentially enteropathogenic bacteria, viruses, and/or chlamydia in both normal and diarrheic calves. Calves were born and raised outside in large pens unless the ambient temperature was below minus 10 degrees F when calving was done inside. Fecal swabs, fecal aliquots, and nasal swabs were taken from each calf at 32, 128 plus or minus 3, and 248 plus or minus 3 hours of age and as soon after the onset of diarrhea as possible. Diarrhea was defined as that condition in which the feces contained less than 10% dry matter. Enteropathogenic Escherichia coli in feces were identified using the ligated gut loop procedure in calves and by feeding broth cultures to colostrum fed lambs seven to 16 hours old. Potentially enteropathogenic viruses were detected using a variety of methods which included tissue culture, fluorescent antibody, hemadsorption, and electron microscope techniques. Of the 40 calves studied, 32 (80%) developed diarrhea before ten days of age. Twenty-two strains of Escherichia coli which caused dilation of calf ligated intestinal loops were isolated from 11 scouring calves and from one normal calf. Nine out of ten strains of Escherichia coli which dilated ligated loops also caused diarrhea when fed to colostrum-fed lambs seven to 16 hours old. Using antibody technique a Reo-like virus was detected in the feces of 15 calves before, during, and after the onset of diarrhea. Four calves excreted both loop dilating strains of E. coli and Reo-like virus in the feces before ten days of age; in all cases the loop dilating E. coli were isolated from the feces prior to the demonstration of Reo-like virus. A Corona-like virus was also demonstrated in three of the 15 calves infected with Reo-like virus and a noncytopathogenic strain of bovine virus diarrhea virus was isolated from two of the 15 calves infected with Reo-like virus. A loop dilating strain of Citrobacter was isolated from one diarrheic calf. There was no consistent pattern of onset or duration of diarrhea in calves which excreted different infectious agents. Salmonella species, infectious bovine rhinotracheitis virus, parvovirus, adenoviruses, parainfluenza-3 virus, and Chlamydia species could not be demonstrated in any of the calves or their dams. No potentially enteropathogenic agents could be demonstrated in 11 of the 32 calves which scoured. These findings emphasize the complexity of the infectious aspect of the neonatal diarrhea syndrome and illustrate the difficulty in making an etiological diagnosis in field outbreaks of the calf scours complex.  (+info)

Protective effect of immunoglobulins in serum and milk of sows exposed to transmissible gastroenteritis virus. (6/337)

Experimental exposure of susceptible pregnant sows by various routes to the gut-origin transmissible gastroenteritis virus stimulated production of milk and serum antibodies. These antibodies neutralized the cytopathic effect of transmissible gastroenteritis virus propagated in cell culture. This in vitro neutralizing antibody resided in the IgG and IgA immunoglobulin classes. On the other hand, protection for baby pigs resided in the IgA class of milk immunoglobulin of sows exposed orally or intramammarily but not of sows exposed intramuscularly to the virus.  (+info)

Differential detection of transmissible gastroenteritis virus and porcine epidemic diarrhea virus by duplex RT-PCR. (7/337)

Transmissible gastroenteritis (TGE) and porcine epidemic diarrhea (PED) are highly contagious enteric diseases of piglets. The clinical signs of these diseases are very similar and include watery, yellowish diarrhea. Thus, the effective differential detection of TGE virus and PED virus is required. In the present study, a duplex reverse transcription-polymerase chain reaction (RT-PCR) was established for the differential detection of TGE and PED viruses. The primers were designed for the S gene of each virus. RNA was extracted from the intestines and stool samples that were collected from the swine with diarrhea. The RT-PCR test could detect both TGE and PED viruses with 2 TCID50/200 microl. Among 90 clinical samples, 7 TGE viruses and 2 PED viruses were detected by the duplex RT-PCR. This duplex RT-PCR may be a useful diagnostic method for the rapid, specific, and sensitive differential detection of TGE and PED viruses using clinical samples.  (+info)

The sialate-4-O-acetylesterases of coronaviruses related to mouse hepatitis virus: a proposal to reorganize group 2 Coronaviridae. (8/337)

Group 2 coronaviruses are characterized within the order Nidovirales by a unique genome organization. A characteristic feature of group 2 coronaviruses is the presence of a gene encoding the haemagglutinin-esterase (HE) protein, which is absent in coronaviruses of groups 1 and 3. At least three coronavirus strains within group 2 expressed a structural protein with sialate-4-O-acetylesterase activity, distinguishing them from other members of group 2, which encode an enzyme specific for 5-N-acetyl-9-O-acetylneuraminic acid. The esterases of mouse hepatitis virus (MHV) strains S and JHM and puffinosis virus (PV) specifically hydrolysed 5-N-acetyl-4-O-acetylneuraminic acid (Neu4,5Ac2) as well as the synthetic substrates p-nitrophenyl acetate, 4-methylumbelliferyl acetate and fluorescein diacetate. The K(m) values of the MHV-like esterases for the latter substrates were two- to tenfold lower than those of the sialate-9-O-acetylesterases of influenza C viruses. Another unspecific esterase substrate, alpha-naphthyl acetate, was used for the in situ detection of the dimeric HE proteins in SDS-polyacrylamide gels. MHV-S, MHV-JHM and PV bound to horse serum glycoproteins containing Neu4,5Ac2. De-O-acetylation of the glycoproteins by alkaline treatment or incubation with the viral esterases resulted in a complete loss of recognition, indicating a specific interaction of MHV-like coronaviruses with Neu4,5Ac2. Combined with evidence for distinct phylogenetic lineages of group 2 coronaviruses, subdivision into subgroups 2a (MHV-like viruses) and 2b (bovine coronavirus-like viruses) is suggested.  (+info)

CLAIM. Fabricated genetic sequences were used to support the hypothesis that the virus arose naturally DETAILS. Inadequate support: The preprint by Yan et al. offers no evidence to support their claim that the genetic sequences of other coronavirus strains were fabricated to support the hypothesis that SARS-CoV-2 arose naturally.Incorrect: The fact that multiple coronavirus strains share highly similar or identical genetic or protein sequences is not evidence that those viruses were fabricated. Shared genetic or protein sequences is common among viruses that belong to the same family and indicates their evolutionary relatedness. KEY TAKE AWAY. There is no evidence supporting the claim by Yan et al. that genetic sequences of several coronaviruses were fabricated to support the hypothesis that SARS-CoV-2 arose naturally. The presence of highly similar or identical gene and protein sequences are common among organisms that are evolutionarily related to each other. Therefore, it is expected that ...

Infectious bronchitis, a disease of chickens caused by Avian coronavirus infectious bronchitis virus (IBV), leads to severe economic losses for the poultry industry worldwide. Various attempts to control the virus based on vaccination strategies are performed. However, due to the emergence of novel genotypes, an effective control of the virus is hindered. In 1996, a novel viral genotype named IBV-QX was reported for the first time in Qingdao, Shandong province, China. The first appearance of an IBV-QX isolate in Europe was reported between 2003 and 2004 in The Netherlands. Subsequently, infections with this genotype were found in several other European countries such as France, Italy, Germany, United Kingdom, Slovenia, and Sweden. The present report describes the use of a new set of degenerate primers that amplify a 636-bp fragment within the S1 gene by reverse transcription polymerase chain reaction to detect the occurrence of IBV-QX infection in Switzerland. ...
Avian infectious bronchitis virus (IBV), a coronavirus, requires initial isolation in, and adaptation to, chicken embryos (CE) before transfer to primary avian cell and chicken tracheal organ cultures. These are the only presently known cell cultures in which IBV replicates and produces cytopathic effects (c.p.e.) in serial passage (Estola, 1966; Cunningham, 1970). Monkey kidney cells have been reported (Fahey & Crawley, 1956; Steele & Luginbuhl, 1964) to support relication of IBV without c.p.e. when first inoculated with virus propagated in CE. Attempts apparently were not made to passage the virus in these cells. Direct haemagglutination (HA) is not a normal property of IBV (Biswal, Nazerian & Cunningham, 1966) or of the human coronaviruses (Kapikian, 1969). However, human coronaviruses OC 38 and OC 43 adapted to suckling mouse brain (McIntosh et al. 1969) cause direct HA (Kaye & Dowdle, 1969) and produce syncytia and plaques in African green monkey kidney and BSC-1 cells (Bruckova,

A virulent avian infectious bronchitis virus (IBV) was isolated from 30-day-old broiler chickens that exhibited respiratory symptoms, nephropathologic lesions, and a high proportion of deaths in the Peoples Republic of China during 2005. The strain, designated YN, was genetically and pathologically characterized. Phylogenetic analysis showed that YN and most of the previously characterized IBV isolates found in China were phylogenetically classified into 2 main genetic clusters. The YN isolate caused severe lesions and resulted in deaths of 65% in experimental infections of 30-day-old specific-pathogen-free chickens. Tracheal and severe kidney lesions developed in all infected birds, confirming the ability of YN strain to induce both respiratory and renal disease. IBV antigens were detected by immunohistochemical analysis in the trachea, lung, kidney, and bursa, consistent with histopathologic observations, virus isolation, and reverse transcription PCR detection. We showed that YN IBV exhibits severe
The epididymal region of the rooster consists of the rete testes, the efferent ductules and the epididymal duct. In the epididymal region, the spermatozoa gain the ability to move and acquire surface proteins. The specialized microenvironment of the epididymal region is vital for these developments to occur. A dysfunction of the epididymal region, epididymal stones, has been shown to affect fertility in the rooster. The cause of these epididymal stones was investigated and avian infectious bronchitis virus (AIBV) has been identified as a cause. AIBV is a highly contagious respiratory disease in chickens. The pathogenesis of AIBV in the female reproductive tract has been well studied; however, there have been few studies concerning the effects of AIBV on the rooster reproductive tract. Therefore this investigation was undertaken to identify the role of AIBV in epididymal stone formation and to characterize changes in seminal plasma composition. Specific objectives were: (1) to determine if AIBV ...
A virus isolated from a respiratory disease in chickens was identified as infectious bronchitis virus (IBV). By serum neutralisation tests the virus was shown to be serologically distinct from the Massachusetts type but to possess a one-way relationship with the Connecticut type. Experimentally, it caused a relatively mild respiratory disease in baby chicks. Vaccination of young chicks with H-120 Massachusetts IBV vaccine afforded a high degree of protection against challenge with the isolate. Some problems relating to the isolation and classification of field strains of IBV are briefly discussed.. ...
Looking for online definition of Coronaviridae in the Medical Dictionary? Coronaviridae explanation free. What is Coronaviridae? Meaning of Coronaviridae medical term. What does Coronaviridae mean?
Avian infectious bronchitis virus (IBV) is a major respiratory disease-causing agent in birds that leads to significant losses. Dendritic cells (DCs) are specialised cells responsible for sampling antigens and presenting them to T cells, which also play an essential role in recognising and neutralising viruses. Recent studies have suggested that non-coding RNAs may regulate the functional program of DCs. Expression of host non-coding RNAs changes markedly during infectious bronchitis virus infection, but their role in regulating host immune function has not been explored. Here, microarrays of mRNAs, miRNAs, and lncRNAs were globally performed to analyse how avian DCs respond to IBV. First, we found that IBV stimulation did not enhance the maturation ability of avian DCs. Interestingly, inactivated IBV was better able than IBV to induce DC maturation and activate lymphocytes. We identified 1093 up-regulated and 845 down-regulated mRNAs in IBV-infected avian DCs. Gene Ontology analysis suggested that

Avian infectious bronchitis (IB), caused by avian infectious bronchitis virus (IBV), is a worldwide endemic disease of chickens that affects all branches of the poultry industry. Multiple geno/serotypes occur, and low vaccine cross-protection results from the highly divergent IBV types. In view of the lack of consistent data on the economic losses caused by IB and the poor protection resulting from the use of the Massachusetts type as a live vaccine in Brazil, this survey aimed to estimate the losses per 1,000 birds in broiler and breeder flocks positive for IBV. Thirty-two different IBV genetic types were found. In breeders, the total loss per 1,000 birds was US$3,567.4 and US$4,210.8 at 25-26 and 42 weeks old, respectively, whereas in broilers (48 days old), the estimated loss was US$266.3 per 1,000 birds. Taken together, the results show a significant and measurable economic impact on the broiler and breeder industries, with an age-dependent increasing trend and an association with multiple ...
Over the past years the research, we have been able to clone and propagate full length coronavirus (CoV) cDNAs from several CoVs using vaccinia virus as eukaryotic cloning vector. The reverse genetic system is based upon the in vitro transcription of infections RNA from a cloned full-length cDNA copy of a CoV genome, and the introduction of nucleotide changes, deletions or insertions is facilitated by vaccinia virus-mediated recombination. The reverse genetic system has proven to be rapid, robust and versatile and is available in the laboratory of Dr. Thiel for the generation of recombinant prototype viruses of all major CoV phylogenetic lineages, namely for HCoV 229E, type-I and type-II Feline CoVs (genus Alphacoronavirus), Mouse Hepatitis Virus strain A59, SARS-CoV (genus Betacoronavirus), Avian Infectious Bronchitis Virus (genus Gammacoronavirus).. One of our long-term goals is to study CoV replication in order to develop strategies to prevent and control CoV infections. Thus, we have applied ...

Infectious bronchitis virus (IBV) variants constantly emerge and pose economic threats to poultry farms worldwide. Numerous studies on the molecular and pathogenic characterization of IBV variants have been performed between 2007 and 2017, which we have reviewed herein. We noted that viral genetic mutations and recombination events commonly gave rise to distinct IBV genotypes, serotypes and pathotypes. In addition to characterizing the S1 genes, full viral genomic sequencing, comprehensive antigenicity, and pathogenicity studies on emerging variants have advanced our understanding of IBV infections, which is valuable for developing countermeasures against IBV field outbreaks. This review of IBV variants provides practical value for understanding their phylogenetic relationships and epidemiology from both regional and worldwide viewpoints.
Virus classification of Infectious Bronchitis virus (IBV) according to reverse transcriptase polymerase chain reaction or virus neutralization.
This thesis deals with the molecular characterization and detection of infectious bronchitis virus (IBV), an important pathogen that causes heavy losses in the poultry populations worldwide. The aim of the research was to better understand the molecular characteristics of the virus and to investigate the factors behind the continuous emergence of new genetic variants and the occurrence of outbreaks. The studies showed that the viral genome is under a continuous evolution, due to mutations, strong selective pressure and recombination events. These forces lead to a wide genetic diversity and the generation of new variants of this virus. The viral genes encoding the spike, envelope and membrane proteins can be considered the main genomic regions, which are indicating the evolution processes of IBV. The various strains contain specific structural and functional motifs in their genes and the alterations in these motifs may affect the infection biology of the virus. The constant emergence of new ...
The nucleotide sequences of a region including S1, S2, 3a, 3b and E genes of twenty-seven infectious bronchitis virus (IBV) isolates in Korea between 1990-2011 were determined and phylogenetic and computational recombination analyses were conducted. The sizes of coding regions of some genes varied among IBV isolates due to deletion or insertion of nucleotides; the nucleotide similarities of S1, S2, 3a, 3b and E genes among the 27 isolates were 75.9%-100.0%, 85%-100.0%, 64.0%-100.0%, 60.4%-100.0% and 83.1%-100.0%, respectively. According to phylogenetic analysis of S1 gene, the 27 isolates were divided into five genotypes, Mass, Korean-I (K-I), QX-like, KM91-like and New cluster 1. The phylogenetic trees based on the S2, 3a, 3b, E genes and S1-S2-3a-3b-E (S1-E) region nucleotide sequences did not closely follow the clustering based on the S1 sequence. The New cluster 1 prevalent during 2009 and 2010 was not found in 2011 but QX-like viruses became prevalent in 2011. The recombination analysis revealed
Whats further perplexing about the situation is the fact that it took two months for the full gene sequence of this mutated coronavirus strain to be released by the National Institute of Virology, which received it a while back after it was collected from a patient in Kerala.. Why it took this Indian government agency so long to release it has created more questions than there are answers as to just how serious this situation truly is. Even more concerning is a warning put out by the South China Morning Post, admittedly a communist Chinese government propaganda outlet, that theres much more to come in the area of mutations.. [T]here is real concern growing that thousands of strains sampled and sequenced are just the tip of the iceberg - and great variety increases the risk that new strains will require new vaccines in the same way the flu virus does, the paper reported.. Even so, the race is on to release one, two, or even seven, in the case of billionaire eugenicist Bill Gates, different ...

CARMEN RODRÍGUEZ HERNÁNDEZ, JUAN CARLOS SANZ MORENO. Published: 11 September 2020. http://www.doi.org/10.37201/req/086.2020. The coronavirus are a wide group of viruses among that the SARS-CoV-2 is included (family Coronaviridae, subfamily Coronavirinae, genus Betacoronavirus and subgenus Sarbecovirus). Its main structural proteins are the membrane (M), the envelope (E), the nucleocapsid (N) and spike (S). The immune response to SARS-CoV-2 involves the cellular and the humoral sides, with neutralizing antibodies fundamentally directed against the S antigen. Although the seroprevalence data are frequently assumed as protection markers, no necessarily they are. In Spain, it is estimated that, to assure the herd immunity, at least four-fifths of the population should be immunoprotected. Due the high fatality rate of COVID-19, the acquisition of the protection only by the natural infection it not assumable and other measures as the mass immunization are required. Currently, there are several ...
Animal health company, Zoetis, has obtained a full license from the US Department of Agriculture (USDA) to sell Poulvac Bron GA 08, the first commercially available vaccine to reduce disease caused by Georgia 2008 (GA 08) Type infectious bronchitis virus (IBV) in poultry.
The following is from a medical forum. The writer, who is a widely respected professional scientist in the US, prefers to stay anonymous, because presenting any narrative different than the official one can cause you a lot of stress in the toxic environment caused by the scam which surrounds COVID-19 these days. - Julian Rose. ***. I work in the healthcare field. Heres the problem, we are testing people for any strain of a Coronavirus. Not specifically for COVID-19. There are no reliable tests for a specific COVID-19 virus. There are no reliable agencies or media outlets for reporting numbers of actual COVID-19 virus cases. This needs to be addressed first and foremost. Every action and reaction to COVID-19 is based on totally flawed data and we simply can not make accurate assessments.. This is why youre hearing that most people with COVID-19 are showing nothing more than cold/flu like symptoms. Thats because most Coronavirus strains are nothing more than cold/flu like symptoms.

New covid-19 strains are being discovered from various parts of the world and are partly being blamed for the sudden surge in cases in several regions. Here is a look at the coronavirus strains discovered recently that are thought to be more dangerous than the prevalent strain.
The World Health Organization has suggested that disease names should not include geographical markers. (See the citation and excerpt at the end of this message.) Hence, the name of the infectious disease causing the current pandemic deliberately did not include Wuhan, China, or Asian. Instead, the name Covid-19 was constructed. Interestingly, the major news organizations are not following this advice when reporting about variants of Covid-19. For example, the names UK variant and South African variant are employed in news reports from CNN and BBC. Perhaps this will change over time. Here is a report from CNN last month. The title prominently features the name UK variant. The accompanying video shows the Director of the CDC Rochelle Walensky, and she uses the term B117 variant, but the journalists mention UK variant. Website: CNN Title: UK variant is now the dominant coronavirus strain in the US, says CDC chief Author: Betsy KIein (CNN) Date: April 7, 2021 ...

Feline Infectious Peritonitis Virus Model of a feline coronavirus. Coronaviridae (such as FIPV) are enveloped RNA viruses that are common in the intestinal tract of cats.…
Monocytes infected with feline infectious peritonitis virus, a coronavirus, express viral proteins in their plasma membranes. barrier. One minute after internalisation started, vesicles had passed the cortical actin, co-localised with microtubules and association with myosin 6 was lost. The vesicles were further transported over the microtubules and accumulated at the microtubule organising centre after 10 to 30?min. Intracellular trafficking over microtubules was mediated by MLCK, myosin 1 and a small actin tail. Since inhibiting MLCK with ML-7 was so efficient in blocking the internalisation pathway, this target can be used for the development of a new treatment for FIPV. Introduction Two genetically highly similar biotypes of coronaviruses are described in cats: feline infectious peritonitis virus (FIPV) and feline enteric coronavirus (FECV). These coronaviruses can infect both cats and other members of the Felidae family. An infection with FECV is usually sub-clinical, except in young ...
TY - JOUR. T1 - Feline infectious peritonitis viruses arise by mutation from endemic feline enteric coronaviruses. AU - Vennema, Harry. AU - Poland, Amy. AU - Foley, Janet E. AU - Pedersen, Niels C. PY - 1998/3/30. Y1 - 1998/3/30. N2 - Feline infectious peritonitis virus (FIPV) strains from six cats and three different geographic areas were compared genetically with feline enteric coronavirus (FECV) isolates obtained from cats inhabiting the same environments. Sequence comparisons were made from 1.2- to 8.9-kb segments on the 3 end of the genome. FECV/FIPV pairs from the same catteries or shelters were 97.3-99.5% related but were genetically distinct from FIPV and FECV strains obtained from cats living in geographically distinct environments. The high genetic similarity between FECVs and FIPVs from the same environment strongly suggested a common ancestry. Based on the presence of deletion mutations in the FIPVs and not in the FECVs, it was concluded that FIPVs evolved as mutants of FECVs. The ...
Cell-mediated immunity is thought to play a decisive role in protecting cats against feline infectious peritonitis (FIP), a progressive and lethal coronavirus disease. In view of the potential of DNA vaccines to induce cell-mediated responses, their efficacy to induce protective immunity in cats was evaluated. The membrane (M) and nucleocapsid ... read more (N) proteins were chosen as antigens, because antibodies to the spike (S) protein of FIP virus (FIPV) are known to precipitate pathogenesis. However, vaccination by repeated injections of plasmids encoding these proteins did not protect kittens against challenge infection with FIPV. Also, a prime boost protocol failed to afford protection, with priming using plasmid DNA and boosting using recombinant vaccinia viruses expressing the same coronavirus proteins. Because of the role of IL-12 in initiating cell-mediated immunity, the effects of co-delivery of plasmids encoding the feline cytokine were studied. Again, IL-12 did not meet expectations ...
Feline infectious peritonitis is a fatal viral disease which is currently incurable by drugs. Also, there are no effective vaccines. Cyclosporin A (CsA) was recently shown in vitro to exert potent antiviral activities on several virus-host systems, including various coronaviruses. However, whether CsA has clinically relevant activity in vivo resistant to various coronaviruses, including the severe acute respiratory syndrome and Middle East respiratory syndrome coronaviruses, remains unknown. Herein, the authors report that treatment with CsA caused a sustained reduction in pleural fluid volume and viral copy number in a cat diagnosed with effusive feline infectious peritonitis. ...

Infectious bronchitis virus (IBV) is a member of family Coronaviridae and is classified into group 3 of the Coronaviruses. The virus is a single-stranded positive-sense RNA virus with a genome of 27kbp. IBV is a highly infectious disease of chickens that results in high morbidity with moderate to severe mortality depending on the strain involved, age of the birds, and immune status of the chickens. Multiple worldwide investigations indicate that differentiation within the S1 glycoprotein gene can lead to serotype variation within the IBV species. In this study 46 isolates collected over two years from broiler and broiler breeder flocks and eight historical isolates were analyzed. Forty one isolates originated from the KwaZulu-Natal region whilst the remaining thirteen were isolated from 4 other poultry-dense provinces. The S1 gene was sequenced and compared to determine variation between South African isolates, as well as global sequences submitted to Genbank. The results indicate the division ...

Structural protein that makes short spikes at the surface of the virus. Contains receptor binding and receptor-destroying activities. Mediates de-O-acetylation of N-acetyl-4-O-acetylneuraminic acid, which is probably the receptor determinant recognized by the virus on the surface of erythrocytes and susceptible cells. This receptor-destroying activity is important for virus release as it probably helps preventing self-aggregation and ensures the efficient spread of the progeny virus from cell to cell. May serve as a secondary viral attachment protein for initiating infection, the spike protein being the major one. May become a target for both the humoral and the cellular branches of the immune system.
This could end up being important for the COVID-19 vaccine. Hypothetically speaking, if SARS-CoV-2 works like Dengue, which is also caused by an RNA virus, then anyone who has not tested positive for SARS-CoV-2 might actually be at increased risk for severe COVID-19 after vaccination, and only those who have already recovered from a bout of COVID-19 would be protected against severe illness by the vaccine.. To be clear, we do not know whether that is the case or not, but these are important areas of inquiry and the current vaccine trials will simply not be able to answer this important question.. The Swiss Medical Weekly paper9 also reviews the evidence of ADE in coronavirus infections, citing research showing inoculating cats against the feline infectious peritonitis virus (FIPV) - a feline coronavirus - increases the severity of the disease when challenged with the same FIPV serotype as that in the vaccine.Experiments have shown immunization with a variety of SARS vaccines resulted in ...

Kannan Ganapathy (University of Liverpool) talked about the epidemiology, prevention and control of this disease, during Avicolas Porcinos 2018 in Buenos Aires, Argentina.
An ongoing outbreak of SARS-CoV-2 has raised global concerns in 2020 with millions of confirmed cases, which is identified as another clade within the Betacoronavirus genus, Coronaviridae family. This article will help to figure out how this kind of virus infect human body by introducing the interaction between the four stages of the life cycle of coronavirus and the cytoskeleton.. The first stage: virus invasion. The first stage of coronavirus infection is Spike(S) protein-mediated attachment to the cell surface via S protein to the ceramide acid portion (acidic carbohydrate with 9 carbon atoms) or heparan sulfate. This infection strategy is very effective because there are many types of receptor molecules on the surface of all mammalian cells, thus creating abundant conditions for plasma membrane attachment. After binding, the virus particles actively rearrange the cytoskeleton by regulating the FAK/Cofilin/Rac/Cdc42 pathway.. The second stage: transport. In the second phase, some studies ...
