Yersinia enterocolitica is an important pathogen to animals and humans. Thirteen strains of Y. enterocolitica were isolated from diseased fish. The partial 16SrDNA gene, five virulence genes, pathogenicity, and drug resistance of Y. enterocolitica strain G6029 were studied using molecular biological technology and toxicological method. Results showed that the length of amplified 16SrDNA sequenc...

Enterotoxic capacities of 95 Yersinia enterocolitica strains isolated from fattening pigs by the use of the suckling mouse bioassay were investigated. A positive result was received for 14 strains (14.74%), doubtful for 33 strains (34.74%), while the rest of 48 strains (50.52%) did not induce the production of enterotoxins. The received results show that in the pig population there are almost 1...

Yersinia enterocolitica was isolated from human mesenteric lymph nodes. Its morphological characteristics and biochemical and serological reactions are described.

A comparison of heat-stable enterotoxins from Escherichia coli and Yersinia enterocolitica by the suckling mouse bioassay showed that whereas E. coli heat-stable enterotoxin evoked a maximum ratio of gut weight to remaining body weight after a 4-h incubation period, the maximum ratio for Y. enterocolitica was achieved at 2 h, decreasing thereafter to values regarded as negative (less than 0.083...

pGC1, a self-transmissible lac plasmid that originated in Yersinia enterocolitica 842, is described. This plasmid is freely transmissible between strains of Y. enterocolitica and from such strains to strains of Escherichia coli. The plasmid can also be transferref among G. coli strains and back to Y. enterocolitica, although at a greatly reduced frequency. pGC1 has a molecular weight of about 3...

The major reservoir of Yersinia enterocolitica and the main source of risk posed to human health are pigs. The objective of this study was to develop a method for pigs immunization with a suspension of immunogenic strains of Y. enterocolitica and to analyze the impact of this immunization on the course of immunological processes in animals, and thus to search for possibilities of preventing or ...

The first shotgun genome sequence of a microbial pathogen from the Philippines is reported. Yersinia enterocolitica subsp. palearctica strain PhRBD_Ye1 is the first Y. enterocolitica strain sequenced from an animal source, swine, which is a natural source of yersiniosis. The closest phylogenetic match is a human clinical isolate from Germany.

Yersinia enterocolitica is the most common bacteriological cause of gastrointestinal disease in many developed and developing countries. Although contaminated food is the main source of human infection due to Y. enterocolitica, animal reservoir and contaminated environment are also considered as other possible infection sources for human in epidemiological studies. Molecular based epidemiologic...
