identification of antigenic variants of the porcine rubulavirus in sera of field swine and their seroprevalence.we sampled sera from 1013 non-vaccinated swine from four states in mexico, guanajuato, jalisco, michoacán and the estado de mexico, to analyse anti-porcine rubulavirus antibody titres against three different porcine rubulavirus isolates (pac-4/1993, pac-6/2001, and pac-9/2003) using a hemagglutination inhibition assay. the results revealed that there were antigenic differences among the isolates assessed. in particular, the estimated correlation between the pac-4/1993 and pac-6/2001 (0.50) isola ...201122171991
