Yersiniosis was the fourth reported zoonosis in the European Union in 2018. As well-known, pigs are recognized important reservoirs of Yersinia enterocolitica. The study was focused on Y. enterocolitica detection in mesenteric lymph nodes and faeces of 305 wild boars, but Yersinia bercovieri was more common, being isolated from 108 animals (35.4%). Cold season (p = 1.17 9 10-5) and young age (p = 0.004) significantly increased Y. bercovieri detection. Y. enterocolitica 1A belonging to six serotypes (O:4.32-4.33; O:5; O:6.30-6.31; O:7.8-8-8.19; O:10-34; O:12.25-12.26) was isolated from 8.2% (25/305) of the animals. Cold season significantly affected (p = 0.037) Y. enterocolitica detection.
