The infective and immunogenic properties of Salmonella cholerae suis in weaner pigs

Abstract

Extract

Salmonella cholerae suis (Salmonella suipestifer) is the cause of an infectious disease of weaner pigs which manifests itself as either a chronic enteritis or as an acute septicaemia in which the organism rapidly invades the body tissues and fluids. Although pigs of all ages can contract the disease, experience in New Zealand has shown that young pigs from eight to twelve weeks old are more susceptible. In 1947. experiments were commenced at Wallaceville to examine the possibility of protecting young pigs by inoculation with vaccines prepared from strains of S. cholerae suis isolated in this country. The purpose of this paper is to record and discuss the results of these experiments.
