| Abstract | Genotype G5 group A rotavirus (RV-A), which is common in pigs and also detected in horses and cattle, circulated as endemic genotype in the 1980s and early 1990s in Brazil. After 1996, G5 RV-A has been replaced by G9 RV-A, becoming only sporadically detected. Recently, G5 has been reported in children with severe diarrhea in Argentina, Cameroon, Paraguay, People's Republic of China, and Vietnam, suggesting that, although uncommon in humans, it has a worldwide distribution. In a previous study, Brazilian G5 RV-A VP7 gene analysis demonstrated the existence of three main lineages: I, II, and III; all Brazilian strains and three porcine strains from Thailand grouped inside Lineage I. The VP8(*) subunit of VP4 gene showed that all P[8] strains fell into three major genetic lineages: P[8]-1; P[8]-2; and P[8]-3. Partial sequencing and phylogenetic analysis of VP1, VP2 and VP3 genes of P[8]G5 human RV-A strains were determined from 28 Brazilian strains collected from 1986 to 2005. The VP1-VP3 partial sequences analysis showed that the Brazilian strains have high amino acid identity with the human RV-A prototype IAL28 and other Wa-like genogroup strains. It was also shown that G5 RV-A Brazilian VP1-VP3 and VP7 sequences have a similar pattern of gouping: The study strains and the G5 prototype strain IAL-28 grouped together, while other prototypes, like OSU grouped separately. These results suggest that the core protein genes (VP1-VP3) of the G5 RV-A Brazilian strains might have originated from porcine and human strains. Phylogenetic analyses of VP7, VP4, VP1, VP2, and VP3 genes of P[8]G5 strains revealed a conserved genomic constellation (G5-P[8]-R1-C1-M1) with sequence similarity to Wa-like strains: IAL28, Wa, BE00048, CK00032, CK00033, DC4772 and DC1898, suggesting that despite the differences in genotypes (i.e., G5, G1 and G3) these viruses are genetically similar. The results presented here are fundamental to understand the epidemiology and evolution of genotype G5 RV-A and demonstrate the importance of continuous monitoring and molecular characterization of RV-A strains circulating in human and animal populations. | pt_BR |
