A meta-analysis on experimental infections with porcine circovirus type 2 (PCV2).
A meta-analysis was performed with the aim to identify factors with a relevant influence on the expression of clinical postweaning multisystemic wasting syndrome (PMWS) under experimental conditions. Data from 44 studies were included in the analysis. Several variables were studied: number of pigs in the experiment, intake of colostrum, serological status against porcine circovirus type 2 (PCV2...
متن کاملMutant USA strain of porcine circovirus type 2 (mPCV2) exhibits similar virulence to the classical PCV2a and PCV2b strains in caesarean-derived, colostrum-deprived pigs
In 2012, a mutant porcine circovirus type 2 (mPCV2) strain was identified in cases of PCV-associated disease (PCVAD) in the USA. The mPCV2 had an additional amino acid, lysine (K), in the capsid at position 234. The objectives of this study were to compare the pathogenicity of mPCV2, PCV2a and PCV2b in pigs using biologically pure infectious virus stocks derived from respective infectious DNA c...
متن کاملIn vivo emergence of enterotoxigenic Escherichia coli variants lacking genes for K99 fimbriae and heat-stable enterotoxin.
Neonatal pigs were inoculated with porcine enterotoxigenic Escherichia coli 431, which carries genes for K99 fimbriae and STaP enterotoxin. Colonies of strain 431 were recovered from feces of pigs for up to 17 days after inoculation and tested for hybridization with gene probes for K99 and STaP. Variants of strain 431 that did not hybridize with the probes were considered to have lost the genes...
متن کاملA comparison of virulence of intraperitoneal infection of Burkholderia mallei strains in guinea-pigs
Male guinea pigs show high susceptibility to Burkholderia mallei and have been used as animal models in glanders studies. The purpose of our study was to elucidate glanders comparative pathogenesis in guinea pigs. We present here the histological changes and bacterial isolation that develop over time in guinea pigs inoculated intraperitoneally (IP) with two strain of B. mallei. Ten male guinea ...
متن کاملTitle: Demonstration of pathogenicity in CDCD pigs with a cytopathic agent isolated from farm with “Sow abortion and mortality syndrome”
A previously unidentified cytopathic agent along with PRRS virus was isolated from farms with history of severe abortion and sow mortality. Pathogenic role of the agent was not known in pigs. The objective was therefore to investigate clinical disease in cesarian derived colostrum deprived (CDCD) pigs following experimental inoculation with the agent. Molecular and serologic characteristics of ...
