Identification of a novel GC-rich 113-nucleotide region to complete the circular, single-stranded DNA genome of TT virus, the first human circovirus. (1/377)

The sequence data (H. Okamoto et al., Hepatol. Res. 10:1-16, 1998) of a newly discovered single-stranded DNA virus, TT virus (TTV), showed that it did not have the terminal structure typical of a parvovirus. Elucidation of the complete genome structure was necessary to understand the nature of TTV. We obtained a 1.0-kb amplified product from serum samples of four TTV carriers by an inverted, nested long PCR targeted for nucleotides (nt) 3025 to 3739 and 1 to 216 of TTV. The sequence of a clone obtained from serum sample TA278 was compared with those registered in GenBank. The complete circular TTV genome contained a novel sequence of 113 nt (nt 3740 to 3852 [=0]) in between the known 3'- and 5'-end arms, forming a 117-nt GC-rich stretch (GC content, 90.6% at nt 3736 to 3852). We found a 36-nt stretch (nt 3816 to 3851) with an 80.6% similarity to chicken anemia virus (CAV) (nt 2237 to 2272 of M55918), a vertebrate circovirus. A putative SP-1 site was located at nt 3834 to 3839, followed by a TATA box at nt 85 to 90, the first initiation codon of a putative VP2 at nt 107 to 109, the termination codon of a putative VP1 at nt 2899 to 2901, and a poly(A) signal at nt 3073 to 3078. The arrangement was similar to that of CAV. Furthermore, several AP-2 and ATF/CREB binding sites and an NF-kappaB site were arranged around the GC-rich region in both TTV and CAV. The data suggested that TTV is circular and similar to CAV in its genomic organization, implying that TTV is the first human circovirus.  (+info)

Evidence that a plant virus switched hosts to infect a vertebrate and then recombined with a vertebrate-infecting virus. (2/377)

There are several similarities between the small, circular, single-stranded-DNA genomes of circoviruses that infect vertebrates and the nanoviruses that infect plants. We analyzed circovirus and nanovirus replication initiator protein (Rep) sequences and confirmed that an N-terminal region in circovirus Reps is similar to an equivalent region in nanovirus Reps. However, we found that the remaining C-terminal region is related to an RNA-binding protein (protein 2C), encoded by picorna-like viruses, and we concluded that the sequence encoding this region of Rep was acquired from one of these single-stranded RNA viruses, probably a calicivirus, by recombination. This is clear evidence that a DNA virus has incorporated a gene from an RNA virus, and the fact that none of these viruses code for a reverse transcriptase suggests that another agent with this capacity was involved. Circoviruses were thought to be a sister-group of nanoviruses, but our phylogenetic analyses, which take account of the recombination, indicate that circoviruses evolved from a nanovirus. A nanovirus DNA was transferred from a plant to a vertebrate. This transferred DNA included the viral origin of replication; the sequence conservation clearly indicates that it maintained the ability to replicate. In view of these properties, we conclude that the transferred DNA was a kind of virus and the transfer was a host-switch. We speculate that this host-switch occurred when a vertebrate was exposed to sap from an infected plant. All characterized caliciviruses infect vertebrates, suggesting that the host-switch happened first and that the recombination took place in a vertebrate.  (+info)

Ultrastructure of porcine circovirus in persistently infected PK-15 cells. (3/377)

The ultrastructure of porcine circovirus was examined in persistently infected porcine kidney (PK)-15 cells. Virus-infected PK-15 cells had large numbers of intracytoplasmic inclusions, and a few cells had intranuclear inclusions. Intracytoplasmic inclusions were dispersed throughout the cytoplasm but were most numerous in the perinuclear cytoplasm. Inclusion were of various sizes, round to oval, and electron dense and were of two general types. Inclusions of the first type were small (0.1-0.5 microm diameter), not surrounded by trilaminar membranes, and granular with indistinct margins that blended with surrounding cytoplasm. Some contained 12+/-2-nm-diameter icosahedral virions in loose aggregates or rarely forming paracrystalline arrays. Small inclusions could be sites of viral assembly or maturation. Intracytoplasmic inclusions of the second type were larger (0.5-5.0 microm diameter) and more numerous and had abrupt margins surrounded by trilaminar membranes. They were more electron dense than small inclusions and were heterogeneous, containing various proportions of aggregated virions, electron-dense crystalline lamellae of 5 nm periodicity, and/or whorls of myelinoid membranes. Virions usually formed paracrystalline arrays and occasionally were loosely aggregated. Larger inclusions were typical of autophagolysosomes. Intranuclear inclusions were not membrane bound and were often associated with reticulated nucleoli or aggregates of heterochromatin. Some inclusions were irregularly shaped aggregates of indistinct, circular 10-12-nm-diameter viruslike particles. Others were 0.1-1.0 microm in diameter, round or ring shaped, dense, and finely granular, with sharply demarcated margins.  (+info)

Electron microscopical observations of psittacine beak and feather disease in an Umbrella cockatoo (Cacatua alba). (4/377)

Psittacine beak and feather disease (PBFD) was diagnosed in an umbrella cockatoo (Cacatua alba) with severe feather dystrophy and loss. Electron microscopically, the intranuclear and intracytoplasmic inclusion bodies observed by light microscopy were composed of viral particles forming paracrystalline arrays, whorls, semicircles or concentric circles. Recovered viral particles from the skin and feather follicle tracts were icosahedral and 15 to 20 nm in diameter.  (+info)

Detection of porcine circovirus from lesions of a pig with wasting disease in Japan. (5/377)

A wasting disease characterized by progressive weight loss and dyspnea has been observed in weaning pigs on a farm in Yamagata Prefecture in 1998. Histopathologic findings in an affected pig were bronchointerstitial pneumonia and intracytoplasmic clusters of basophilic inclusions in macrophages of lymph nodes, which were similar to those in pigs with postweaning multisystemic wasting syndrome (PMWS) recently reported in North America and Europe. Porcine circovirus (PCV)-like particles were observed in bronchial lymph node of the pig by electron microscopy, and PCV antigens were detected in the lesions by immunohistochemical staining. PCV DNA was also detected in the lung and tonsil by PCR, and restriction fragment length polymorphism analysis of the PCR products with HinfI showed the same type of the PCV associated with PMWS (pmws PCV). Homology of nucleotide sequences between the PCR product and corresponding regions of published pmws PCV genomes was very high. These results indicated that virus detected in this study was pmws PCV. To our knowledge, this is the first report on the presence of pmws PCV in Japan.  (+info)

Multiplex PCR for detection and typing of porcine circoviruses. (6/377)

Sets of oligonucleotide primers were designed according to the sequences of the open reading frames (ORFs) ORF1 and ORF2 of the prototype nonpathogenic PK-15 strain of porcine circovirus (PCV) type 1 (PCV-1). By the PCR performed with the various primer sets, genomic DNA or RNA from other bacterial or viral pathogens of the respiratory tracts of pigs could not be amplified. A positive amplification reaction could be visualized with DNA extracted from a viral suspension containing as few as 10 viral particles per ml. No DNA fragment could be amplified from lysates of continuous porcine cell lines (PT, ST, and PFT cells) known to be negative for PCV. When tested with clinical samples from pigs, the results of the single PCR method showed nearly 93% (13 of 14 samples) correlation with histopathological and immunohistochemical findings. Interestingly, subclinical PCV infections could be detected by single PCR with clinical samples that have been submitted from animals with irrelevant cases of respiratory and/or enteric problems. On the basis of the nucleotide sequences of PCV strains (PCV-2) recently associated with outbreaks of postweaning multisystemic wasting syndrome (PWMS) in Quebec, Canada, pig farms, other primers were designed from the PCV-1 genome, and these primers failed to amplify genomic fragments specific to the ORF1 or ORF2 genes of clinical isolates associated with PWMS but amplified DNA from the PCV-1 strain. Two rapid multiplex PCR (mPCR) methods have been developed to distinguish between both genotypes of PCV. By those two mPCR methods, (i) species-specific primer pairs were used to amplify a DNA fragment of 488 bp specific for the ORF2 genes of both genotypes, whereas a 375-bp fragment was amplified from the ORF1 gene of the PCV-1 strain only, or (ii) species-specific primer pairs were used to amplify a DNA fragment of 646 bp specific for the ORF1 genes of both genotypes, whereas a 425-bp fragment was amplified from the ORF2 gene of the PCV-1 strain only. By both mPCR methods, a PCV-2 infection was demonstrated in tissues of 94.2% (33 of 35) of the sick pigs tested, in agreement with previous findings showing the close association of this new genotype of PCV with outbreaks of PMWS in Europe and North America. On the other hand, a PCV-1 infection was confirmed in only 5.7% (2 of 35) of the pigs, and confirmation of a mixed infection with PCV-2 was obtained by a single PCR with PCV-2-specific primers.  (+info)

PCR detection and characterization of type-2 porcine circovirus. (7/377)

A polymerase chain reaction (PCR) assay was developed for detecting porcine circovirus (PCV). The assay readily detected type-2 PCV (PCV-2) and type-1 PCV (PCV-1). The PCR primers were designed based on DNA sequences conserved in all reported PCV genomes. Type 1 PCV and type 2 PCV both produced 438 bp amplification products, which were easily identified and differentiated from one another by restriction fragment length polymorphism (RFLP) analysis. Porcine circovirus was detected in 55% (931/1693) of randomly tested pigs with various clinical signs and lesions, most of which were difficult to differentiate from those associated with porcine reproductive and respiratory syndrome (PRRS). The PCR products from all positive clinical samples were identified by RFLP to be only PCV-2; DNA tested by PCR was extracted directly from one or more of lung, mesenteric or mediastinal lymph nodes, and tonsil. Type 2 PCV was also detected in 6% (2/34) of DNA extracted directly from semen of randomly chosen healthy boars. Positive PCR reactions from 554 diseased pigs were characterized by RFLP and categorized into 5 different profiles (A-E), of which 82.8% were PCV-2A (456/554), 3.0% were PCV-2B (17/554), 9.9% were PCV-2C (55/554), 1.1% were PCV-2D (6/554), and 3.2% were PCV-2E (18/554). The complete genomic nucleotide sequences of PCV-2A, B, C, D, and E were determined and found to have at least 95% homology compared with one another and with all other PCV-2 found in the GenBank database. All PCV-2 had less than 76% homology with PCV-1. This PCR assay will hopefully be useful to veterinary diagnostic laboratories for routine testing and surveillance of infection with PCV-2. The RFLP profiling system might be useful for preliminary characterization and identification of PCV isolates and might also benefit studies on the molecular epidemiology of PCV.  (+info)

Porcine circoviruses: a review. (8/377)

Porcine circoviruses (PCV) are small nonenveloped DNA viruses containing a unique single-stranded circular genome. Previously, no recognized link was found between PCV infection of pigs and disease, and PCV was considered a nonpathogenic agent. Over the last 5 years, a "novel" PCV, designated PCV2, has been associated with various disease syndromes in pigs, primarily postweaning multisystemic wasting syndrome (PMWS). Pigs with PMWS have a variety of clinical signs, including debility, dyspnea, palpable lymphadenopathy, diarrhea, and pallor or icterus. Lesions associated with the presence of PCV2 in a variety of cell types include lymphohistiocytic to granulomatous interstitial pneumonia, hepatitis, nephritis, myocarditis, enteritis, and pancreatitis. The lesions of PMWS have been reproduced experimentally after inoculation of piglets with PCV2 cell culture isolates, although the full expression of the disease syndrome may require the presence of other agents such as porcine parvovirus or porcine reproductive and respiratory syndrome (PRRS) virus. Recent reports have linked PCV2 to other disorders in pigs, ranging from abortion and reproductive failure to "atypical" PRRS. Available data indicate high seroprevalence of antibodies to PCV2 worldwide. The diagnosis of PCV2-associated disease is based on the direct demonstration of PCV2 antigens or nucleic acid in affected tissues. PCV2 is now regarded as an important emerging pathogen. Although vertical transmission has been documented, the epidemiology of PCV2 infections is poorly understood, as is the role of the immune response in controlling or augmenting disease.  (+info)

Porcine circovirus-associated diseases (PCVAD), caused by porcine circovirus type 2 (PCV2), threaten the pig industry worldwide. Five genotypes of PCV2 were recently identified: PCV2a, PCV2b, PCV2c, PCV2d and PCV2e. In addition, a novel porcine circovirus from a case of a sow with dermatitis, nephropathy syndrome and reproductive failure has been identified based on metagenomic analysis and classified as porcine circovirus type 3 (PCV3). Therefore, the current study was conducted to determine the prevalence and genetic characteristics of PCV2 and PCV3 in clinical samples. A total of 471 samples (161 tissue samples of lungs and lymph nodes from 34 farms and 310 serum samples from 47 farms) were tested for PCV2. Among them, 171 samples from 59 farms that had been positive for PCV2 were genotyped. Another 690 samples (296 tissue samples of lungs and lymph nodes from 91 farms, 108 samples of aborted foetuses from 26 farms, and 286 serum samples from 47 farms) were tested for PCV3. Based on PCV2 genotyping

The clinico-pathological scope of this viral infection has been expanded over time. From the initial description of postweaning multisystemic wasting syndrome, some enteric, respiratory and reproductive disorders have been subsequently linked with PCV2. Porcine dermatitis and nephropathy syndrome, an immunocomplex disease, has also been associated with infection by this virus. All together, these conditions have been grouped under the name of porcine circovirus diseases (PCVD) or porcine circovirus associated diseases (PCVAD). The precise mechanisms by which a PCV2 infected pig develops a PCV2 subclinical infection or a clinical PCVD/PCVAD are still to be fully elucidated, but inferences ...

Porcine circovirus associated disease - WikipediaPorcine circovirus associated disease - Wikipedia
Porcine circoviral disease (PCVD) and Porcine circovirus associated disease (PCVAD), is a disease seen in domestic pigs. This disease causes illness in piglets, with clinical signs including progressive loss of body condition, visibly enlarged lymph nodes, difficulty in breathing, and sometimes diarrhea, pale skin, and jaundice. PCVD is very damaging to the pig-producing industry and has been reported worldwide. PCVD is caused by porcine circovirus type 2 (PCV-2). The North American industry endorses PCVAD and European use PCVD to describe this disease. Postweaning multisystemic wasting syndrome (PMWS) is the classic PCVD entity, caused by PCV-2. PCV-2 has a near universal distribution - present in most pig herds. In contrast, PMWS is more sporadic in its distribution. Experimental induction of PMWS has not been achieved by PCV-2 infection alone, using infectious DNA clones of the virus or a pure form of PCV-2 derived from infectious DNA clones. Therefore, it is assumed that PMWS is a ...

Porcine circovirus type 2 (PCV2) causes postweaning multisystemic wasting syndrome (PMWS) in growing pigs but generally requires the presence of other infectious or non-infectious factors to produce the full clinical expression of disease. These factors remain to be identified, but management routines, concurrent infections and maternal immunity are thought to influence the risk for PMWS outbreak in swine herds. Pigs presenting with PMWS develop severe immunosuppression and the work of this thesis focuses on the interaction between PCV2 and the immune system of the pig in vivo and in vitro. Development of PMWS was studied in models for experimental infection in young pigs using coinfections with porcine parvovirus (PPV) or Escherichia coli. Three-day-old colostrum-deprived pigs infected with PCV2 and PPV developed severe PMWS, and a possible role for interleukin 10 as well as impaired production of antibodies to PCV2 in the development of disease was observed. Four-week-old colostrum fed pigs ...

Bioafrica Evidence for recombination in natural populations of porcine circovirus type 2 in Hong Kong and mainland China
Porcine circovirus type 2 (PCV2) belongs to the family Circoviridae, and is the causative agent of post-weaning multisystemic wasting syndrome (PMWS) in pigs. In this study, phylogenetic analyses of three complete PCV2 genomic sequences from Hong Kong suggest that natural recombination happened among different lineages of PCV2. A preliminary investigation of the parental strains of these potential recombinants was carried out using bootscanning. Statistical significance of this recombination event was tested and positions of the potential recombination breakpoints were estimated in a maximum-likelihood framework. The recombinant breakpoints were estimated to be located within the origin of replication (ori) and replicase (rep) gene of PCV2. Interestingly, several GenBank sequences of PCV2 in mainland China were found to have a recombination pattern similar to that of the potential PCV2 recombinants from Hong Kong, implying that this recombinant genotype might already be widespread within ...

Porcine circovirus type 3 (PCV3) is a newly emerging circovirus that might be associated with porcine dermatitis and nephropathy syndrome, reproductive failure, and cardiac and multisystemic inflammation. To aid the prevention and control of the infectious disease caused by PCV3, we developed a novel isothermal amplification assay using polymerase spiral reaction (PSR), which allows the visual detection of preserved strains and clinical samples. This assay precisely amplified the PCV3 genome with the use of a water bath at 62 °C for 50 min. The detection limit was found to be 1.13 × 102 copies/μL by gel electrophoresis or with the use of a visible dye (an indicator comprising phenol red and cresol red). No cross-reaction with other porcine infectious viruses was observed. The detection results for 23 PCV3-positive samples by PSR were in accordance with loop-mediated isothermal amplification (LAMP) assay. The detection rate of the PSR assay for PCV3 positivity of clinical samples was 68/97, which was

Porcine circovirus type 2 (PCV2) is considered to be an important emerging pathogen associated with a number of different syndromes and diseases in pigs known as PCV2-associated diseases. It has been responsible for significant mortality among pigs and remains a serious economic problem to the swine industry worldwide leading to significant negative impacts on profitability of pork production. In this study we have demonstrated that PCV2 capsid (Cap) protein based virus-like particles (VLPs) were efficiently produced in yeast S. cerevisiae and induced production of monoclonal antibodies (MAbs) reactive with virus-infected cells. Moreover, PCV2 Cap VLPs served as a highly specific recombinant antigen for the development of an indirect IgG PCV2 Cap VLP-based ELISA for the detection of virus-specific IgG antibodies in swine sera. Four hundred-nine serum samples collected from pigs in Lithuania were tested for PCV2-specific IgG to determine the sensitivity and specificity of the newly developed ELISA in

PORCINE CIRCOVIRUS - PAMFA
IDENTIFICATION AND USE: Porcine circoviruses are small, icosahedral viruses that were discovered in 1974 as contaminants of a porcine kidney cell line. They were later called circoviruses when their genome was found to be a circular, single-stranded DNA molecule. Upon entry into cells, the viral ssDNA genome enters the nucleus where it is made double-stranded by host enzymes. It is then transcribed by host RNA polymerase II to form mRNAs that are translated into viral proteins. There is some evidence that circoviruses might have evolved from a plant virus that switched hosts and then recombined with a picorna-like virus.. Porcine circoviruses are classified in the Circoviridae family, which contains two genera, Circovirus and Gyrovirus. There are two porcine circoviruses, PCV-1 and PCV-2; only the latter causes disease in pigs.

Porcine circovirus type 2 (PCV2) associated reproductive disease was diagnosed in a herd containing only gilts. A single case of abortion occurred and no other disorder was evident in the herd. PCV2 antigen and/or DNA were detected in two aborted fetuses. One of the fetuses, revealing both PCV2 DNA and antigen, presented multinucleated giant cells, severe vascular lesions (intramural oedema, fibrinoid necrosis, mild lympho-histiocytic vasculitis, fibrin thrombi) and mild non-suppurative inflammation in the lungs. Other abortifacient infections were not found. This is the only report of PCV2-induced abortion in Hungary since 1999, when PCV2-associated disease was first discovered in the country. ...

Open reading frame 2 (ORF2) of porcine circovirus type 2 (PCV2) codes for the 233 amino acid capsid protein (CP). Baculovirus-based vaccines that express only ORF2 are protective against clinical disease following experimental challenge or natural infection. The goal of this study was to identify regions in CP preferentially recognized by sera from experimentally infected and vaccinated pigs, and compare these responses to pigs diagnosed with porcine circovirus-associated disease (PCVAD). The approach was to react porcine sera with different CP polypeptide fragments that each contained one or more immunoreactive regions. Expression of polypeptides was performed using E.coli. Initial results showed that sera from vaccinated pigs preferentially recognized only the largest CP(43-233) polypeptide fragment and showed low levels of binding to other CP polypeptide fragments. The results of sera from pigs diagnosed with PMWS showed only minimal reactivity with CP polypeptide fragments, including the ...

Porcine circovirus type 2 (PCV2) is the primary causative agent of postweaning multisystemic wasting syndrome (PMWS), whereas the ubiquitous porcine circovirus type 1 (PCV1) is nonpathogenic for pigs. Since its initial detection in a Canadian commercial swine herd in 1991, PMWS has been detected in all swine producing regions of the world and is now a serious economic problem to the swine industry. The objectives of this dissertation were to biologically, genetically and experimentally characterize both PCV1 and PCV2, to identify the genetic determinant(s) for virulence and replication, and to develop an effective genetically-engineered vaccine against PCV2 infection and PMWS. The genetic heterogeneity of PCV2 and PCV1 isolates from different geographic origins were determined. We found that, although PCV1 and PCV2 genomes were very conserved, some minor genomic variation exists among PCV1 isolates and PCV2 isolates. The nonpathogenic PCV1 and pathogenic PCV2 share only about 76% nucleotide ...

Duck circovirus - WikipediaDuck circovirus - Wikipedia
The Duck circovirus (DuCV) is a type of virus found in ducks. Strains of the virus have predominantly been found in China, though strains have also been isolated from ducks in Germany and the United States. Duck circovirus is a small nonenveloped virus with a monomeric single-stranded circular DNA genome. DuCV has been clustered in the Circoviridae family genus Circovirus, according to the eighth report of the International Committee on Taxonomy of Viruses. Scientists have studied the Duck circovirus by using polymerase chain reaction (PCR)-based methods and dot blot hybridisation (DBH) tests. Infection with DuCV appears to cause growth disorders in ducks as well as eventual immunosuppression due to depletion of lymphatic cells. It was found that ducks between the ages of 40∼60 days were more susceptible to Duck circovirus. There was no evidence showing that the DuCV virus was capable of vertical transmission. The symptoms are immunosuppression, stunting in growth, and also feather ...

Porcine circovirus 2 (PCV2) is the primary cause of post-weaning multisystemic wasting syndrome, in which it stimulates a strong IL-8 response that is associated with chronic inflammation as well as lesions in the lymphoid organs. However, the mechanism underlying PCV2-induced IL-8 production is still unclear. In the present study, we demonstrated that increased IL-8 expression during PCV2 infection depends on Toll-like receptor (TLR2), but not TLR4 or TLR9 signalling pathways in porcine alveolar macrophages. Moreover, we found that impairment of the MyD88/NF-κB signalling pathway by MyD88 knockdown or NF-κB inhibitors markedly decreased PCV2-induced IL-8 secretion. These results suggest that PCV2 induces IL-8 secretion via the TLR2/MyD88/NF-κB signalling pathway. Therefore, it is important to elucidate the molecular mechanisms of the PCV2-induced inflammatory response.

Australian porcine circoviruses - Murdoch Research RepositoryAustralian porcine circoviruses - Murdoch Research Repository
Two types of porcine circovirus (PCV) exist, referred to as PCV1 and PCV2. PCV2 has been associated with disease syndromes in pigs, including that designated postweaning multisystemic wasting syndrome (PMWS), which has been identified in all regions of the world bar Australia (Hamel et al., 1998; Allan et al., 1999a; Onuki et al., 1999; Martelli et al., 2000; Kyriakis et al., 2000; Wellenberg et al., 2000; Done et al., 2001; Trujano et al., 2001; Saradell et al., 2004; Castro et al., 2004; Jemersic et al., 2004; Maldonado et al., 2004; Wang et al., 2004; Motovski and Segales, 2004; Garkavenko et al., 2005). PMWS affects young weaner pigs and results in weight loss, tachypnea, dyspnea, enlarged lymph nodes and jaundice (Harding, 1998). PCV2 may also cause or contribute to other swine diseases such as congential tremors (CT) (Stevenson et al., 1999), porcine dermatitis and nephropathy syndrome (PDNS) (Rosell et al., 2000), reproductive failure (Meehan et al., 2001) and several other emerging ...

The study conducts the first phylogenetic analysis of PCV2 in Chile. PCV2 isolated from Chilean intensive swine farms, covering over the 90% of the pork production, resulting a complete national perspective of PCV2. The results confirm the high presence of PCV2b (52%) and less represented PCV2a (14%). Surprisingly, 34% of sequences were PCV2a/PCV2d recombinant viruses. The no amplification of these 10 sequences by the selective PCR was further explained due to these primers were not able to amplified PCV2d, the major parenteral of these viruses. Furthermore, we were not able to detect PCV2d variant in the Chilean PCV2 diversity even if was the major parent of the recombinant viruses, probably this event occurred years before and the recombinant remained. PCV2a and PCV2b, and the recombinant viruses were found since 2005. Nevertheless, were not observed geographical, temporal and other patterns, most likely due to there is not enough sequences per farm.. Recently, a large-scale study determinates ...

Animal circoviruses belong to the Circovirus genus of the Circoviridae family. Nowadays, only swine and birds were identified as circovirus hosts. Circoviruses have a single-stranded circular genome of approximately 2000 nucleotide long. DNA of these viruses possesses : (i) a nonanucleotide sequence essential for replication, flanked by inverted repeat sequences, a palindrome that has the potential to form a stem-loop structure and (ii) two major ORFs, located on the viral and complementary strands, which encode respectively the replication-associated protein (Rep) and the capsid protein (Cap). All the circoviruses described at the present time, except porcine circovirus of type 1, are associated with immunosuppressive or immunodepressive diseases. Histopathological lesions such as cytoplasmic inclusions of virus in histiocytic cells and T and B lymphocyte depletion in lymphoid organs, are commonly noticed. No medical prophylaxis of circovirus infections is currently available.. ...

In 2016, two small-scale fattening pig farms (about 200 or 300 American Landrace pigs in total), locating in Guangdong province (southern China) and Jilin province (northern China) separated by more than 3, 000 km in distance (Fig. 1), suffered from severe respiratory disease (SRD). Pigs (2-3 months old) on both farms have received immunizations against PCV2, pseudorabies virus (PRV), classical swine fever virus (CSFV) and type 2 porcine reproductive and respiratory syndrome virus (PRRSV). However, the morbidity rate of pigs on the two farms was approximately 60%, the mortality in affected pigs was about 80%. From autopsy results of 18 individual dead pigs (n = 8 for farm A, n = 10 for farm B) (Additional file 1: Table S1), the similar macroscopic lesions were concentrated in the lungs and lymph nodes, which was characterized by PRRSV- or PCV2-like lesions including pulmonary interstitial widening, congestion and lymphadenopathy bleeding.

Canine Circovirus (CanineCV) is an emerging virus which since its first report in USA in 2012, it has been described worldwide. It was the second mammalian circovirus species identified in dogs and its role in canine enteritis is still being uncertain as much as its association in disease with the Canine Parvovirus-2 (CPV-2). Here, we aim to confirm for the first time the presence of CanineCV in Colombia and to develop phylogenetic evolutive analyses of CanineCV in CPV-2 positive animals. DNA from samples were extracted and PCR, full genome sequencing and phylogenetic analysis was performed to detect and characterize CanineCV. From a total of 30 CPV-2 positive samples, 16.6% (n = 5) were positives for CanineCV. Sequencing analysis of Colombian CanineCV wild-type strains displayed high identity to each other (99.5-99.7% nt; 99.7% aa). The full genome phylogenetic analysis confirmed that worldwide reported CanineCV strains were separated into four distinct genotypes in addition to a European origin of the

N2 - Histological examination of the bursae from 12 pigeons under 4 months old revealed basophilic globular inclusion bodies, 5 to 25 microns in diameter, in the cytoplasm and the nuclei of the various bursal follicular cells. Electron microscopy of these inclusions revealed large electron-dense areas containing non-enveloped icosahedral viral particles, 14-19 nm in diameter, either loosely arranged or in paracrystalline array. Similar basophilic globular inclusion bodies were seen in the spleen and cecal tonsils of a few pigeons and in the duodenum of one pigeon. There were various degrees of lymphoid depletion in the bursa, spleen, and bone marrow. The morphology of the inclusions in the bursa and size of the viral particles are ...

Research on Swine Respiratory Diseases Beyond PRRS Now Eligible for Funding | The Pig SiteResearch on Swine Respiratory Diseases Beyond PRRS Now Eligible for Funding | The Pig Site
The Respiratory Disease Research Board (formerly the PRRS Research Review Board), with financial support from Boehringer Ingelheim Vetmedica, Inc. (BIVI), is pleased to announce an expansion of the Research Award program to include additional respiratory pathogens.. Beginning in 2016, the Awards for Advancing Research in Respiratory Disease (formerly PRRS Research Awards) will also be open to research projects related to porcine circovirus Type 2 (PCV2), Mycoplasma hyopneumoniae and influenza A virus in swine (IAV-S). This is the first time in the boards history that projects covering diseases beyond PRRS will be considered.. We recognize that there are a host of other respiratory disease challenges besides PRRS that impact production and performance, says Dr Daryl Olsen, AMVC veterinarian and member of the Respiratory Disease Research Board.. This expansion is exciting because it shows our commitment to meeting the industrys broad needs for ongoing, applicable swine respiratory disease ...

Animal Health/Sanidade Animal: Una revisión del Circovirus porcino tipo 2 (I)Animal Health/Sanidade Animal: Una revisión del Circovirus porcino tipo 2 (I)
Con la intención de unificar la terminología para referirse a cada una de estas enfermedades y al conjunto de ellas, se ha propuesto recientemente el término PCVD para referirse al conjunto de enfermedades asociadas a PCV2, y la terminología que figura en la tabla para referirse a cada una de las PCVD (Segalés, 2012). En cuanto a la enfermedad reproductiva por PCV2, cabe añadir que recientemente se ha vinculado PCV2 a SMEDI (S-stillbirth-nacidos muertos, M-mummification-momificación, ED-embryonic death-muerte embrionaria e I-infertility-infertilidad) en primíparas (Meyns y col., 2012). Otra enfermedad que todavía hoy se sigue asociando al virus es el síndrome de dermatitis y nefropatía porcino, a pesar de considerarse una enfermedad mediada por immunocomplejos de la que no se ha demostrado claramente su etiología (Allan y col., 2000a; Rosell y col., 2000; Wellenberg y col., 2004). En los últimos años se está considerando también el impacto de la infección subclínica de los ...

FDA Finds GSKs Rotarix Vaccine Safe for Use | EmaxHealth
Both Rotarix and RotaTeq are designed to protect infants from gastrointestinal illness caused by rotavirus, which kills more than 500,000 infants each year, mostly in low- and middle-income countries. Deaths are rare in the United States, but illness can require a hospital stay due to severe diarrhea. The oral vaccines are typically given to infants between two and six months of age in a two- or three-dose series.. * Read: Ensure Children Receive Vaccinations Before School Starts. An advisory panel for the FDA found that the risk to humans from the porcine (pig) circovirus type 1, or PCV1, was theoretical. Millions of doses of the vaccines have been given to infants with no sign of significant safety problems and PCV1 is not even known to cause health problems in pigs.. Another strain of the virus, PCV2, is believed to cause a wasting syndrome in young piglets, marked by diarrhea and an inability to gain weight, but it is not known to injure humans. Only PCV1 was detected in the Rotarix vaccine, ...
