Molecular Characterization of Porcine Rotaviruses from the Southern Region of Brazil: Characterization of an Atypical Genotype G[9] Strain

Abstract

The G (VP7) and P (VP4) serotype distribution of Brazilian porcine rotaviruses was determined using reverse transcription-PCR genotyping methods. Common porcine G types G3, G4, and G5 were detected in combination with P types [6] and [7]. The detection of nonporcine G types and unusual G-P combinations and the characterization of an atypical virus indicated that interspecies transmission may contribute to the genetic diversity of porcine rotaviruses.

Detection and Genetic Diversity of Porcine Group A Rotaviruses in Historic (2004) and Recent (2011 and 2012) Swine Fecal Samples in Ohio: Predominance of the G9P[13] Genotype in Nursing Piglets

“…Within RVAs there are 27 G genotypes and 35 P genotypes identified to date (6). Twelve G genotypes (G1 to G6, G8 to G12, and G26) and 13 P genotypes (P [1], P [5] to P [8], P [11], P [13], P [19], P [23], P [26], P [27], P [32], and P [34]) have been associated with pigs (3,(6)(7)(8). However, G3, G4, G5, and G11 are the most common G genotypes identified in swine and are usually associated with P [5], P [6], and P [28]; the others are considered less common genotypes in swine (9)(10)(11).…”
