Studies on Yersinia pseudotuberculosis : IV. Isolation of Y. pseudotuberculosis from Healthy Swine

Abstract

A total of 28 strains of Yersinia pseudotuberculosis were isolated from the cecal contents of 2, 041 apparently healthy swine collected from three abattoirs in Kurayoshi, Hiroshima and Fukuoka, respectively. The rate of isolation and the serotype distribution differed from one abattoir to another. Strains of type III were predominant. All the organisms were isolated in the colder months. It should be emphasized that swine are important reservoirs not only for Y. enterocolitica but also for Y. pseudotuberculosis.
