【 摘 要 】

References(10)The present study was made to know the morphology of the initial invasion and lesions involved in the intestinal colonization of Yersinia enterocolitica serovar O3 in the epithelium of Peyer’s patches of mice. Microfold (M) cells formed a specific structure like a pseudopodium and the bacteria were observed on the surface of the pseudopodium-like structure 4 hr after oral administration of serovar O3. The colonies of serovar O3 were observed in the epithelium and the lamina propria of the Peyer’s patches dome region, and the bacteria grown in the Peyer’s patches were in direct contact with the lumen without covered with the host tissue 24 hr after the administration.
