ABSTRACT
Rotavirus is a major cause of infectious diarrhea in infants and young children. The objective of this study was to characterize the genotypes of Human Rotavirus found in children hospitalized with acute diarrhea in the Pediatric Hospital Prof. Hosannah de Oliveira of the UFBA in Salvador, Bahia, Brazil, during the years of 1999, 2000 and 2002. Fecal samples were analyzed (n=358) by methods EIARA and SDS-PAGE for detection of Rotavirus. Positive samples of one or two of these methods (n=168) were submitted to RT-PCR and Multiplex-Nested PCR to determine genotypes G and P. A hundred sixty-eight (46.9 percent) samples were positive and 190 (53.1 percent) negative. Only 17 (4.7 percent) samples had divergent results. The distribution of genotypes G during the first year, showed that the genotype G9 was present in 96,8 percent of the analyzed samples, in the second year, it was responsible for 96 percent and in the third year, 88,1 percent. The characterization of genotypes P demonstrated that the genotype P1A[8] was the most outstanding in all years. In this study we discuss the benefit to control the genotypes of Rotavirus through the molecular characterization for the development of potential vaccines.
