Abstract

Two strains of Yersinia enterocolitica, 03 biovar 4 and 06 biovar 1,were inoculated intragastrically into laboratory rats and mice. The 03 organism began to reside in the intestinal tracts and was excreted in the feces in large amounts during a period of 2 to 4 weeks from the rats and 2 to 10 weeks from the mice which had been inoculated with 10^7 or more cells of the organism. In the mice and rats inoculated with 10^9 cells of the 06 strain, however, there was no evidence of the settling of the organism in the intestinal tract. The serum 0 agglutinin was detected only in half of the animals in which 03 strain became resident.
