MEDEIROS, Beatriz Maria Machado de; SHIMIZU, Mario Tsunezi  and  FALCAO, Deise Pasetto. Period of infectivity of animals challenged by Yersinia sp. Rev. Saúde Pública [online]. 1987, vol.21, n.3, pp.261-264. ISSN 1518-8787.

Conventional swiss mice were innoculated intragastrically (IG) and intravenously (IV) with Yersinia enterocolitica serotypes 0:3, 0:8 and 0:9 and with Yersinia enterocolitica like strains. A control animal group was not innoculated. The period that strains remained in the cecal content after the IG and IV challenge was determined. After IG and IV innoculation, Yersinia enterocolitica serotypes 0:3, 0:8 and 0:9, considered adapted to man, were isolated from the cecal content for a longer period than those considered nonadapted.

Keywords : Yersinia enterocolitica; Mice [microbiology]; Yersinia, infections [microbiology].
