An aim of the study was to evaluate the efficacy of Circovac vaccine in two Polish pig herds affected by post-weaning multisystemic wasting syndrome (PMWS) and reproductive failure. The effectiveness of vaccination was assessed indirectly by analysis of production performance of the examined herds. It was found that Circovac is extremely efficient in reducing losses attributed to PMWS and contr...

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...

The prevalence of different pathogens detected in combination with porcine circovirus type 2 (PCV-2) was studied retrospectively in field cases of postweaning multisystemic wasting syndrome (PMWS) diagnosed at the Iowa State University Veterinary Diagnostic Laboratory, Ames, Iowa, between January 2000, and September 2001. The presence of PCV-2 antigen in lymphoid tissues and/or lung, demonstrat...

A competitive PCR (cPCR) assay was developed for monitoring porcine circovirus (PCV) DNA in serum samples from piglets. The cPCR was based on competitive coamplification of a 502- or 506-bp region of the PCV type 1 (PCV1) or PCV2 ORF2, respectively, with a known concentration of competitor DNA, which produced a 761- or 765-bp fragment, respectively. The cPCR was validated by quantification of a...

These All pig-producing countries from around the world report the presence of Postweaning multisystemic wasting syndrome (PMWS.) In America, PCV2 has been recognized in Canada, United States and Brazil. Knowledge concerning the genetic sequences of PMWS has been very important. In Mexico, there is no report describing the genetic sequences and variations of the PCV2 virus present around the co...

Porcine parvovirus (PPV) coinfection has been shown to increase the incidence and severity of porcine circovirus 2 (PCV2) associated disease in gnotobiotic and in colostrum-deprived pigs. PPV and PCV2 coinfection is also common in the grow-finish pigs in the field today. The objectives of this study were to determine the interactions between PCV2 and PPV in conventional SPF pigs and to determin...

Shandong is a porcine circovirus 2b (PCV2b) strain that was isolated and purified from tissue samples from pigs with postweaning multisystemic wasting syndrome (PMWS) in the Shandong Province of China. Here, we report the complete genome sequence of strain Shandong, which may aid in understanding the molecular characteristics of this strain.

Copyright ©NADIS 2017 Introduction Infection associated with Porcine Circovirus type 2 (PCV2) in pig herds, producing Post Weaning Multisystemic Wasting Disease (PMWS) and Porcine Dermatitis Nephropathy Syndrome (PDNS), appeared in the United Kingdom in the late 1990s and is now ubiquitous. Very few countries in the pig keeping world would claim to be free of the disease, although Australia may...
