Abstract
Fifty eight Yersinia isolates of milk origin were evaluated for their virul ence potential using different established virulence markers. On the basis of colonial morphology on trypticase-soy-agar, only six isolates producing rough margins could be designated as virulent. While congo-red uptake and c alcium-dependent growth revealed four isolates as virulent, at least 19 iso lates were identified as virulent on the basis of crystal violet binding. A uto-agglutination, at the same time, confirmed the virulence in the case of only seven isolates. Thus, no correlation could be established amongst the different markers of virulence of Y. enterocolitica. Hence, none of the te sts alone could be conclusively used for identifying virulent isolates.
