A study of procine enteroviruses isolated from swine in the Toronto area. I. Isolation and serological grouping of viruses.

A number of enteric viruses isolated from swine in the Connaught Medical Research Laboratories and the Mimico Reformatory herds were grouped serologically and compared with previously described porcine enteroviruses. Four of five antigenic types defined were related to other porcine enteroviruses. The fifth was unrelated to any viruses with which it was compared in this study.
