Abstract
In India, studies on the epidemiological and genetic characteristics of enteric viruses in adults with acute gastroenteritis (AGE) are lacking. In this study, fecal samples (n = 110) from adults with acute gastroenteritis in Pune, Western India, were tested for six enteric viruses, and the prevalence of these viruses was as follows: rotavirus A (RVA), 38.5%; enterovirus (EV), 23.1%; astrovirus (AstV), 23.1%; adenovirus (AdV), 7.7%; human bocavirus (HBoV), 7.7%; norovirus (NoV), 0%. Circulation of the RVA G1P[8], G3P[8], G9P[4], CVA-10, echovirus E13, EVC-116, AstV-5, AstV-2, HBoV-1, and AdVC-2 types was observed. When compared to the RotaTeq, Rotarix, and RotaVac vaccine strains, antigenic changes were found in the A, B, C, and F regions of the RVA strains. The circulation of genetically diverse, unusual enteric virus strains, reported here for the first time in adults with acute gastroenteritis, warrants multi-center hospital-based surveillance studies across the country.
