Detection of porcine Circovirus type 2 (PCV2) variants PCV2-1 and PCV2-2 in Brazilian pig population.
In the present study whole genome of six Brazilian isolates of PCV2 were sequenced, analyzed and compared with 35 other sequences (24 from other countries and 17 from Brazil). The phylogenetic analysis showed that mostly Brazilian variants of PCV2 were grouped as PCV2-1. Two isolates among the six analyzed here could not be grouped with any other PCV2-2 analyzed in this study. One of these isolates was from an aborted fetus with myocarditis and the other from a PMWS affected pig. The results pointed here showed that both groups of PCV2 are present in Brazilian pig population without any clear geographical correlation.
