Molecular characterization and phylogenetic analysis of porcine circovirus 2 from Kerala, India.

ABSTRACT: Porcine circovirus type 2 (PCV2), the causative agent of porcine circovirus-associated diseases (PCVADs), has a worldwide distribution, and is considered as one of the most important emerging viral pathogens of economic importance. In Kerala, a total of 62 tissue samples were collected during post mortem from pigs suspected to have died of PCV2 infection. The animals exhibited symptoms like respiratory illness, gradual wasting, rough hair coat, polypnoea, dyspnoea, pallor, diarrhoea, icterus, etc. PCV2 was detected in 36 (58.06%) samples by PCR. Phylogenetic analyses of complete ORF2, and complete genome sequences were carried out and genotypes 2d, 2 h and 2b were detected. The genotype predominant in Kerala was 2d. It was observed that genotypes 2 h and 2b have been recently introduced in
