title: Genotypification of bovine group A rotavirus in México.
abstract: Bovine scours, frequently provoked by rotavirus infection, causes significant economic losses. Nevertheless, no information exists about the bovine rotavirus genotypes present in Mexico. This information is necessary for designing efficient vaccines. In this work, 128 samples from diarrheic calves were collected between 2005 and 2006 in 26 dairy and/or beef cattle herds located in 10 regions of Mexico, and analyzed for the presence of group A rotavirus. G and P genotypes were determined by PCR in rotavirus-positive samples (12/128). Three different genotype combinations were found, G10, P[11]; G6, P[5]; and G10, P[5]; in 67, 25 and 8% of the positive samples, respectively. Some rotavirus-positive animals had been vaccinated with an inactivated rotavirus strain of a different genotype.
