Ultrastructure of porcine circovirus in persistently infected PK-15 cells. (1/285)

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)

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. (4/285)

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. (5/285)

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. (6/285)

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 postweaning multisystemic wasting syndrome in Korean pig: detection of porcine circovirus 2 infection by immunohistochemistry and polymerase chain reaction. (7/285)

This report describes the first diagnosis of porcine circovirus (PCV) infection in weaned pigs with postweaning multisystemic wasting syndrome in Korea by immunohistochemistry and polymerase chain reaction. The most unique lesions were multifocal granulomatous inflammation affecting lymph nodes, liver, and spleen, characterized by infiltrates of epithelioid macrophages and multinucleated giant cells. Circoviral antigen was detected in formalin-fixed sections and was usually present in large, round, dendritic cells in the white pulp of spleen and remnants of follicles in lymph nodes. Lymphoid follicles in the tonsils also contained PCV antigen. A 530-bp DNA fragment of circovirus was successfully amplified from all tested lymph nodes, liver, and spleen.  (+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
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 ...
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 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 ...
TY - JOUR. T1 - Development of a polyclonal-antibody-based immunohistochemical method for the detection of type 2 porcine circovirus in formalin-fixed, paraffin-embedded tissue. AU - Sorden, Steven D.. AU - Harms, Perry A.. AU - Nawagitgul, Porntippa. AU - Cavanaugh, David. AU - Paul, Prem S.. PY - 1999/11. Y1 - 1999/11. N2 - An immunohistochemical method for the detection of type 2 porcine circovirus (PCV2) in paraffin-embedded tissue was developed. Rabbits were inoculated with purified PCV2 to obtain a polyclonal antiserum. Antiserum was applied to sections of porcine tissue that contained lesions consistent with postweaning multisystemic wasting syndrome and in which PCV2 genome had been demonstrated by in situ hybridization. In all cases (18/18), the density and distribution of positive cells detected by in situ hybridization or immunohistochemistry were identical. The immunohistochemical method is more rapid and less expensive than in situ hybridization and is thus more suitable for routine ...
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. Infection probably occurs via oral and respiratory routes, and leads to various diseases including postweaning multisystemic wasting syndrome, and porcine dermatitis and ...

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 ...

Circoviridae is a family of viruses. Birds and mammals serve as natural hosts. There are currently 70 species in this family, divided among 2 genera. Diseases associated with this family include: PCV-2: postweaning multisystemic wasting syndrome; CAV: chicken infectious anemia. Viruses in the family Circoviridae are non-enveloped, with icosahedral and round geometries, and T=1 symmetry. The diameter is around 20 nm. Genomes are circular and non-segmented, around 3.8kb in length. The capsid consists of 12 pentagonal trumpet shaped pentamers. There are two main open reading frames arranged in opposite directions that encode the replication (Rep) and capsid (Cap) proteins. Alternative start codons are common in the avian species. Viral replication is nuclear. Entry into the host cell is achieved by penetration into the host cell. Replication follows the ssDNA rolling circle model. DNA templated transcription, with some alternative splicing mechanism is the method of transcription. The virus exits ...
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 ...
Combination vaccine gives swine industry effective, convenient option. FLORHAM PARK, N.J., Aug. 20, 2014 - Fostera™ PCV MH - the porcine circovirus (PCV) and Mycoplasma hyopneumoniae (M. hyo) combination vaccine that was built from the ground up by Zoetis - now has the longest demonstrated duration of immunity (DOI) to help protect pigs from porcine circovirus-associated disease (PCVAD) caused by PCV Type 2 (PCV2).

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.. ...

Zoetis launched Fostera PCV MH on the US market. The vaccine is a one-bottle, one-dose combination vaccine that helps protect swine from Porcine Circovirus-associated disease (PCVAD) and enzootic pneumonia caused by Mycoplasma hyopneumoniae (M. hyo).
article{326621, abstract = {Stimulation of the porcine immune system causes increased replication of porcine circovirus 2 (PCV2) in vivo. In the present study, we investigated whether various cytokines (interleukin-1 [IL-1], IL-6, IL-10, tumor necrosis factor-alpha [TNF-alpha], interferon-alpha [IFN-alpha], and IFN-gamma) are able to influence PCV2 infection in vitro. No changes were observed in IL-1, IL-6, TNF-alpha, or IL-10-treated cells. However, it was demonstrated that IFN-alpha and IFN-gamma influenced PCV2 infection in porcine kidney cells (PK-15) and porcine monocytic cells (3D4/31). IFN-gamma added to the culture medium before, during, or after inoculation increased the number of PCV2 antigen-positive cells, respectively, by 418%, 171%, and 691% in PK-15 cells and by 706%, 114%, and 423% in 3D4/31 cells. IFN-alpha pretreatment decreased the number of infected PK-15 cells. When it was added after inoculation, IFN-alpha enhanced PCV2 infection by 529% in PK-15 cells and by 308% in 3D4/31 ...
Porcine Circovirus 2 (PCV2) has been intriguing pig producers and scientists alike as it proved difficult to identify both the disease's origins and triggers. In this third episode of the series 'PCVD - From pathogenesis to protection', Pig Progress launches an attempt to unveil as many mysteries as possible that surround PCV2.

Protection Against Evolving Virus. DURHAM, N.C., March 3, 2018 - Zoetis has introduced Fostera® Gold PCV MH, the U.S. pork industrys first vaccine to include two genotypes of porcine circovirus type 2 (PCV2) - 2a and 2b.. Together, the two genotypes provide the broadest range of protection against evolving PCV2 viruses in U.S. swine herds. The vaccines efficacy against 2d - the most prevalent PCV2 genotype - was demonstrated in a large field trial.. "Were pleased to introduce a vaccine that brings real value to the U.S. pork industry - one that provides broader protection against PCV2 genotypes and, more importantly, helps to minimize performance problems due to the virus, reduce monetary losses for producers and benefit animal welfare," said Lucina Galina, DVM, PhD, director, swine technical services, Zoetis.. The duration of immunity (DOI) with Fostera Gold PCV MH is at least 23 weeks for PCV and Mycoplasma hyopneumoniae (M. hyo), which means the vaccine will protect most herds through the ...
Porcine circovirus type 2 (PCV2), a highly prevalent, economically important swine pathogen is classified into different genotypes (PCV2a-f) based on phylogenetic analysis. Since the introduction of extensive vaccination programs, at least two major shifts have been observed in the prevalence of PCV2 genotypes. The first genotype shift from 2a towards 2b occurred around 2003, while in recent years, we are witnessing the second change in genotype prevalence from the predominant 2b towards 2d. In this study, a PCV2d-2 isolate was characterized as a potential challenge virus for the evaluation of PCV2 vaccine efficacy. Ten-week-old pigs carrying low to moderate levels of maternally derived antibodies to PCV2 were infected with the isolate by the nasal route. Over the next 4 weeks post-infection, the pigs were monitored for the presence of viremia, fecal virus excretion, and humoral immune responses. At the end of the post-infection observation period, samples were taken from the mediastinal and mesenteric
UK - Researchers at the Royal Veterinary College (RVC) have developed an oral vaccine against porcine circovirus type 2 (PCV2) based on the yeast Saccharomyces cerevisiae.
Average daily gain (ADG) and viral load (VL) were evaluated for pigs co-infected with porcine reproductive and respiratory syndrome (PRRS) virus (PRRSV) and porcine circovirus type 2b (PCV2b). Pigs were pre-selected for WUR genotype (a marker on chromosome 4 associated with weight gain and VL under PRRSV-challenge), half were vaccinated for PRRS, and half were not. Results indicate that vaccination for PRRS resulted in slower growth prior to co-infection and that the AB WUR genotype was associated with faster growth prior to co-infection, lower PRRS VL, and lower PCV2b VL in vaccinated pigs.
Factors to be considered for deciding the optimal time of vaccination. Comparison of different vaccination programs in PCV2 subclinically infected piglets.

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 ...

Introduction Real-time PCR tests have been developed to detect and quantify Porcine Circovirus type 2 (PCV2) and Lawsonia intracellularis in pigs faeces. Pooling of individual faecal samples is often used to reduce the costs of diagnostic testing. The objective of this study was to evaluate any change in the test sensitivity of PCV2 and L. intracellularis real-time PCR when individual faecal samples were pooled. Materials and Methods Forty eight faecal samples were collected from the rectum of individual pigs (,10 weeks) from four farms. Faecal samples were classified as diarrhoea +/- based on subjective assessment of consistency. Three individual samples were combined to make 16 pooled samples (8 diarrhoea; 8 non-diarrhoea). Individual and pooled samples were tested using real-time PCR tests specific for PCV2 and L. intracellularis. A positive result in any of the three individual samples was deemed "group positive". Changes in test sensitivity after combining the three individual samples were ...
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.

VP2 of chicken anemia virus (CAV) is a dual-specificity phosphatase required for virus infection, assembly and replication. The functions of the nuclear localization signal (NLS) and nuclear export signal (NES) of VP2 in the cell, however, are poorly understood. Our study identified the presence of a NLS in VP2 and showed that the protein interacted significantly with mini-chromosome maintenance protein 3 (MCM3) in the cell. An arginine-lysine rich NLS could be predicted by software and spanned from amino acids 133 to 138 of VP2. The critical amino acids residues between positions 136 and 138, and either residue 133 or 134 are important for nuclear import in mammalian cells based on systematic mutagenesis. A NES is also predicted in VP2; however the results suggest that no functional NES is present and that this protein is CRM1 independent. It was also shown that VP2 is a chromatin binding protein and, notably, using a co-immunoprecipitation assay, it was found that VP2 association with MCM3 and that
Chicken anaemia virus (CAV) isolate BL-5 VP3 gene was amplified, sequenced and expressed in E. coli as a fusion protein together with a six-histidine tag. The deduced amino acid sequence of VP3 was identical to other CAV isolates Cux-1, A2 and CIA-1 except for a single amino acid substitution at position 12. SDS-PAGE and Western blot analysis indicated that the expressed protein is insoluble and was found primarily from the cell lysate fraction. Expression of the protein was detected as early as 1 h, with maximum expression (~12% of the total protein) at 6 h post induction with IPTG. This study indicates that VP3 protein is highly expressed in insoluble form in E. coli. However, the biological function of the protein remains to be studied ...

The Forest Red-Tailed Black Cockatoo faces "typical" problems such as habitat loss, but is also plagued by several unique threats and an unusual breeding biology…all of which complicated the formation of a recovery plan.. Black Cockatoos have very specific nest-site requirements, and once a suitable nesting hollow is located a pair generally uses it for many years. Over the past several decades, Black Cockatoos in natural habitats have come under pressure from burgeoning populations of feral honeybees and of other cockatoo species, including Galahs and Corellas. These aggressive insects and birds take over Black Cockatoo nests and severely impact the species ability to reproduce. Read More ». ...

The Canberra Cockatoos dominated the 2013 SILVA National Orienteering League, winning three out of four team titles and three individual titles.. The closest team competition was the senior womens. The Cockatoos and defending champions, the Victorian Nuggets, went into the seasons final race level. The Nuggets had a four-minute lead going into the final leg and were still in front at the spectator control, but, as with last year, the title came down to the last few controls of the last race. Jo Allison slipped through for the Cockatoos when Kathryn Preston made a late mistake, and while Preston did her best to come back over the last few controls she fell 50 metres short. A good final week saw the Tassie Foresters in third place.. The Cockatoos senior men led by only a point going into the seasons final week, but always looked to have something in hand, with the return of Dave Shepherd from injury adding depth to an already strong team. The Nuggets still had a mathematical chance of winning ...

This paper examines past occurrences in North America relevant to the possibility of biological disasters with animal origins. With respect to naturally occurring animal disease outbreaks, North America, while not as adversely affected by epizootics as other regions, has had its fair share of such outbreaks of both traditional and emerging animal diseases. The traditional category includes such diseases as anthrax, classical swine fever, bluetongue, brucellosis, foot and mouth disease, and the family of equine encephalomyelitis viruses. The emerging diseases include relatively more recent culprits such as postweaning multisystemic wasting syndrome, poultry enteritis mortality syndrome, and newly discovered examples of the transmissible spongiform encephalopathies. Additionally, several serious diseases of human beings that involve animal vectors or reservoirs occur naturally in North America or have emerged in recent decades; these include plague, hantavirus, monkeypox, West Nile virus and ...
Infection of poultry with chicken anemia virus (CAV) is implicated in several field problems in broiler flocks due to the immunosuppression generated and, consequently, the increased susceptibility to secondary infections. Recently, we have reported an increased occurrence of clinical cases caused by CAV strains distantly related to those commonly used for vaccination. In order to understand the behavior of two Argentinean CAV strains (CAV-10 and CAV-18) in two-week-old chickens, an immune and histopathological study was performed. Neither mortality nor clinical signs were observed in the infected or control groups. Thymus lobes from chickens infected with both CAV viruses were smaller compared to the negative control group. At 14 days post-infection (dpi), only chickens inoculated with CAV-10 show a severe depletion of lymphocytes in the thymus cortex and in follicles from the bursa of Fabricius. Also thymopoiesis disorders, such as reduction in the percentage of total DP (CD4 + CD8α+) thymocytes and

An experiment was conducted to determine the impact of increasing levels of Algamune ZPC (Algal Scientific Corporation, Plymouth, MI) on growth performance and porcine circovirus type 2 (PCV2)-specific immune response of nursery pigs housed under commercial conditions. Algamune ZPC is a polysaccharide-zinc complex feed additive composed of 35% β-1,3-glucan extracted from algae and 10% zinc. A total of 2,484 pigs (PIC 337 × 1050, initially 15.7 lb) were used in a 40-d trial. After feeding a common pelleted diet for 7 d after weaning, pigs were allotted to 1 of 6 dietary treatments in a randomized complete block design with 14 or 16 replicate pens and 27 pigs per pen. All pigs were vaccinated with PCV2 and M. hyopneumoniae vaccines (1 mL Fostera PCV and 1 mL Respisure- One; Zoetis, Florham Park, NJ) at d 3 after birth and at weaning. Blood samples of 72 pigs (12 pens per treatment) were collected on d 2, 18, and 38. The 6 experimental diets were fed in two phases (d 0 to 12 and 12 to 40). ...

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 ...

In patients age 19-64 with a high risk condition (see CDC site below), ACIP has long recommended they receive PCV 23, followed by a 2nd dose 5 years later. PCV 23 is also recommended as a one-time dose for all patients age 65 and over. Now the CDC is recommending, for patients age 19-64 with a high risk conditions, a dose of PCV 13, followed by PCV 23 at least 8 weeks later. For those high risk and in this age group who have already received PCV 23, they should also receive PCV 13 at least 1 year after their dose of PCV 23. Full recommendations are available at the CDC site (CDC site). ...

Afrikaans: Beak and feather disease (BFD), wat veroorsaak word deur Beak and feather disease virus (BFDV) is n dermatologiese toestand wat papegaai spesies versmag. Dit word toenemend moeilik om nie net die beduidende negatiewe ekonomiese impak wat die virus het op die papegaai teling bedryf nie, maar ook die nadelige uitwerking wat dit op die voortbestaan van die endemiese Kaapse papegaai (Poicephalus robustus) te ignoreer.

Porcine circovirus type 2 (PCV2), Mycoplasma hyopneumoniae and Lawsonia intracellularis are economically important pathogens in modern pig breeding and rearing, worldwide. PCV2 infection can be associated with a wide range of diseases, including post-weaning multisystemic wasting syndrome (PMWS), abortion and reproductive failure, the porcine respiratory disease complex (PRDC) and porcine dermatitis and nephropathy syndrome (PDNS) (Allan and Ellis 2000). Porcine proliferative enteropathy, commonly referred to as ileitis, caused by L intracellularis, is a common and widespread intestinal infection in pigs. In its acute form, it can result in mortality in finishing pigs and young breeding stock, and in its chronic form, depression and unevenness of growth in growers and finishers (Lawson and Gebhart 2000). M hyopneumoniae is recognised as the causative agent of porcine enzootic pneumonia, a mild, chronic pneumonia commonly complicated by opportunistic infections with other bacteria (Maes and ...

  • Numbers of studies have broadened our understanding of the roles of p53 signaling in the process of different virus infection and replication. (beds.ac.uk)
  • Those that are present in virions (mature viral particles) are also known as structural proteins, whereas those involved in the assembly, replication and modification of the host innate response to infection are referred to as non-structural proteins. (news-medical.net)
  • Expression of viral proteins and replication of viral DNA was observed, but the infection was not to be passed on to fresh cells, indicating that PCV-infection of human cells is non-productive. (pamfa.org)
  • Viral replication is the term used by virologist s to describe the formation of biological virus es during the infection process in the target host cells. (enacademic.com)
  • Proper infection and production of progeny requires that the cell be in replication as that is when the cell's polymerases are active. (enacademic.com)
  • The monoclonal E3 mAb developed in this study will not only be very useful for detecting CAV infection and performing histopathology studies of infected chickens, but may also be used to purify CAV particles in the future. (bvsalud.org)
  • The identification of these current and past viral infections enriches our knowledge of the cane toad virome, an understanding of which will facilitate future work on infection and disease in this important invasive species. (asm.org)
  • The specificity of binding determines the host species and cell varieties which are receptive to viral infection. (blogkoo.com)
  • This facilitates diagnosis of the infection by polymerase chain reaction (PCR) testing. (thefreelibrary.com)
  • Because tissue culture and serologic methods are not yet available, diagnosis of anellovirus infection relies exclusively on viral DNA detection. (cdc.gov)
  • New techniques described should be used in conjunction with existing tests and should not completely replace conventional techniques for diagnosis of BFDV infection or detection of exposure to the virus. (ufs.ac.za)
  • 16-18 Despite this, evidence of persistent infection has not been systematically established. (bmj.com)
  • 19 Persistent infection with PCV3 was observed during the period between lactation (two to four weeks old) and growing/fattening (10 to 25 weeks old). (bmj.com)
  • However, there exists no information about histopathological lesions caused by infection with porcine TTSuV2. (nih.gov)
  • This study indicated a directly related description of lesions responsible for TTSuV2 infection in swine. (nih.gov)
  • With the development of infection, the sections of tonsil, spleen, hilar lymph nodes and mesenteric lymph nodes showed the normal architecture with no special lesions through the study but only rarely red blood cells in the microvasculation and infiltration of inflammatory cells (lymphocytes and eosinophils) of tonsiland hilar lymph nodes marked by black arrowheads (m, o, p, s. (nih.gov)
  • Focal skin lesions can also be seen which may be accompanied with bacterial infection which is known as blue wing disease. (farm.com.np)
  • Their role as pathogenic entities is well recognized and the array of viral infections throughout the tree of life, including archaea, bacteria, and eukaryotes, is immense. (paperity.org)
  • The young chickens upto 3 weeks are susceptible to the virus infection. (farm.com.np)
  • Generally, CAV infection occurs via vertical transmission in young chicks that are less than two weeks old, which are very susceptible to the disease. (beds.ac.uk)
  • Detection of these sequences suggests that greater genetic diversity may exist among Asfarviruses than previously thought, and raises the possibility that human infection by Asfarviruses may occur. (blogspot.com)
  • Thus, the presence of TTV infection is unlikely to influence the course of chronic hepatitis related to hepatitis B virus (HBV) or hepatitis C virus (HCV) or cause liver diseases in healthy subjects. (bvsalud.org)
  • The future of the endangered giant pandas depends in part on the development of protective measures against infectious diseases, especially viral infection. (biomedcentral.com)
  • This can be used in genetic disorders, autoimmune diseases and viral infections. (news-medical.net)
  • Die studie was uiteengesit om die huidige diagnostiese strategie vir BFDV te evalueer en te verbeter, met beide molekulêre en serologiese tegnieke. (ufs.ac.za)
  • Om polimerase kettingreaksie (PKR) en kwantitatiewe werklike tyd polimerase kettingreaksie (qPCR) as diagnostiese instrumente vir BFDV te vergelyk. (ufs.ac.za)
