BACKGROUND Porcine circovirus type 2 (PCV2) is considered to be the primary causative agent of postweaning multisystemic wasting syndrome (PMWS), which has become a serious economic problem for the swine industry worldwide. The major genotypes, PCV2a and PCV2b, are highly prevalent in the pig population and are present worldwide. However, another newly emerging PCV2b genotype mutant, which has ...

Porcine circovirus type 2 (PCV2) has been associated with a number of disease syndromes in pigs, including post-weaning multisystemic wasting syndrome (PMWS), proliferating and necrotizing pneumonia, porcine respiratory disease complex (PRDC), abortion and reproductive problems (Allan & Ellis, 2000). Porcine dermatitis and nephropathy syndrome (PDNS) and a new ear necrosis syndrome have also be...

The Leprosy Control Programme (LCP) covers 2 1 districts in the three western regions of Nepal, and provides treatment for more than 1 0,000 leprosy patients in about 200 treatment units of the Basic Health Service, and several hospitals/ referral centres . PMWs work at various levels, visiting health posts and running clinics on a pre-fixed date . The number of clinic days per month varies acc...

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 potent...

The aim of this study was to develop and to optimize an immunohistochemistry (IHC) method for PCV2 identification and to compare it with an in situ hybridization (ISH) technique. The results demonstrated that both ISH and IHC successfully detected PCV2 viral antigens or nucleic acid in the examined tissues. Most of the slides identified previously in ISH as PCV2-positive were also positive in I...
