Effects of canine distemper virus infection on lymphoid function in vitro and in vivo.

abstract：:An enterotoxic factor isolated from cultures of Salmonella yielded reproducible results in the suckling mouse model in contrast to other animal models. The enterotoxin appears to possess properties similar to both the heat-stable and heat-labile enterotoxins of Escherichia coli. Preliminary results indicate that the t...
