Abstract
Yersinia pseudotuberculosis
is a foodborne pathogen whose occurrence is poorly understood. One reason for this situation is the difficulty in isolating the species. The methods developed for the isolation of
Yersinia enterocolitica
are not well suited for
Y. pseudotuberculosis
. We therefore designed a protocol which enabled the isolation of
Y. pseudotuberculosis
from a relatively high proportion of PCR-positive wild boar tonsils. The study indicates that wild boars in northeast Germany may carry a variety of
Y. pseudotuberculosis
strains, which differ in terms of their pathogenic potential and other properties. Since wild boars are widely distributed in German forests and even populate cities such as Berlin, they may transmit yersiniae to other animals and crop plants and may thus cause human infections through the consumption of contaminated food. Therefore, the prevalence of
Y. pseudotuberculosis
should be determined also in other animals and regions to learn more about the natural reservoir of this species.
