The study demonstrates the circulation of rotavirus genotypes G1-G4, with a predominance of G1, in Central Brazil.
Supports ongoing rotavirus surveillance in Central Brazil; leaves open implications for regional vaccine effectiveness.
The G genotyping of 74 group A rotavirus samples was done by RNA-DNA hybridization (dot-blot) using oligonucleotide probes for the VP7 gene region of the human rotavirus serotypes/genotypes 1, 2, 3 and 4. Thirty-one samples could be genotyped by dot-blot showing the following results: G1 = 16, G4 = 6, G3 = 5, and G2 = 4. The data show circulation of genotypes G1-G4 and the predominance of G1. The knowledge of genotypes provides important information concerning rotavirus circulation in Central Brazil.
