Human and nonhuman infections caused by Yersinia pseudotuberculosis in Canada from 1962 to 1985.
نویسنده
چکیده
The incidence of human and nonhuman infections of Yersinia pseudotuberculosis in Canada is presented on the basis of a literature review and serotyping of 101 cultures referred to the Canadian National Reference Center for Yersinia enterocolitica and Yersinia pseudotuberculosis.

Direct isolation of Yersinia enterocolitica and Yersinia pseudotuberculosis from meat.
Studies were done to determine the usefulness of dilute alkali (KOH) treatment of meat samples for direct isolation of Yersinia enterocolitica and Yersinia pseudotuberculosis, without enrichment. Virulent Y. enterocolitica and Y. pseudotuberculosis in pork contaminated with 10(2), 10(3), and 10(4) cells per g survived the direct KOH treatment and were never recovered by using KOH postenrichment...
متن کاملComparison of siderophore production and utilization in pathogenic and environmental isolates of Yersinia enterocolitica.
Yersinia enterocolitica strains of serotypes lethal to mice have been reported previously to produce an endogenous siderophore. In this study, an ethyl acetate-extractable siderophore was characterized and given the name yersiniophore. Yersiniophore was produced by 16 of 16 human isolates of serotypes O:4, O:4,32, O:8, O:21, and one nonhuman isolate of serotype O:21. It was not produced by isol...
متن کاملComparative Genomic Hybridization Analysis of Yersinia enterocolitica and Yersinia pseudotuberculosis Identifies Genetic Traits to Elucidate Their Different Ecologies
Enteropathogenic Yersinia enterocolitica and Yersinia pseudotuberculosis are both etiological agents for intestinal infection known as yersiniosis, but their epidemiology and ecology bear many differences. Swine are the only known reservoir for Y. enterocolitica 4/O:3 strains, which are the most common cause of human disease, while Y. pseudotuberculosis has been isolated from a variety of sourc...
متن کاملYersinia pseudotuberculosis produces a cytotoxic necrotizing factor.
Cell extracts from Yersinia pseudotuberculosis induced multinucleation in HEp-2 cells in a manner similar to the effect caused by Escherichia coli cytotoxic necrotizing factor (CNF). The activity was not dependent on the Yersinia 70-kb virulence plasmid, and the activity was not inhibited by antibodies capable of neutralizing E. coli CNF type 1. The nucleotide sequence of the Yersinia cnf gene ...
متن کاملPlasmid DNA relatedness among different serogroups of Yersinia pseudotuberculosis.
Thirteen different serogroup strains of Yersinia pseudotuberculosis and two strains of Yersinia enterocolitica O:3 were examined for the presence of plasmids and plasmid-mediated properties, calcium growth dependency, and autoagglutination. Two Y. enterocolitica strains and eight serogroup (IA, IIA, IIC, III, IVA, VB, VI, and VIII) strains, except for five serogroups (IB, IIB, IVB, VA, and VII)...
