yersinia enterocolitica of porcine origin: carriage of virulence genes and genotypic diversity.yersinia enterocolitica is an important foodborne pathogen, and pigs are recognized as a major reservoir and potential source of pathogenic strains to humans. a total of 172 y. enterocolitica recovered from conventional and antimicrobial-free pig production systems from different geographic regions (north carolina, ohio, michigan, wisconsin, and iowa) were investigated to determine their pathogenic significance to humans. phenotypic and genotypic diversity of the isolates was assessed using anti ...201323320426
yersiniae in pond water and snails.a yersinia enterocolitica serotype 9 was isolated from pond water; y. enterocolitica-like bacteria were also isolated from pond water and from three species of snails (lymnaea palustris elodes, helisoma sp., oxyloma retusa) from the edwin s. george reserve in southeastern michigan. there was evidence for biochemical stability among some of the organisms over a period of years. there also was evidence of transmission of these organisms to snails from the water.197616502684
