Pseudocloacal swabs and palatine tonsils from beavers have been examined for the Yersinia enterocolitica presence. Thirty-six samples from 24 beavers were collected and subjected to bacteriological examinations including sero- and biotypisation. Amplicons confirmed by PCR as Y. enterocolitica were sequenced. Positive samples originated from 4 out of the 24 beavers (16.7 %) and all the strains belonged to biotype 1A. The study suggested that Y. enterocolitica could be isolated from beavers, which may therefore be treated as a reservoir, a significant factor of water contamination and a vector of the Y. enterocolitica.
