Abstract:
The aim of this study was to investigate the genetic diversity of the VP6, VP7, and VP4 genes of 15 Brazilian wild-type porcine RVC strains identified in diarrheic fecal samples. The VP6 gene analysis demonstrated heterogeneity between the 15 RVC strains, which clustered in three distinct genotypes (I1, I5, and I6). In the VP7 and VP4 gene analysis, the genotype combination G6P[4] was detected in only one strain (UEL-77), while G6P[5] was the most commonly (n = 14) detected in RVC strains identified in the Brazilian pig herds evaluated, indicating its probable predominance in this country, mainly in 2014.
