Pathogenesis (disease development)
In Yersinia enterocolica, the serogroups O:3, O:5, O:8, O:9 can be distinguished. O:3 is responsible for approximately 90% of infections. The pathogen reservoir is various animals, but pigs are considered the main reservoir for the human pathogenic serotypes. Transmission occurs mainly through contaminated food, mainly of animal origin, and contaminated drinking water. In rare cases, direct transmission by infected persons may also occur.
