| 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 ... | 2013 | 23320426 |
