Mycobacterium caprae transmission to free-living grey wolves (Canis lupus) in the Bieszczady Mountains in Southern Poland

Abstract

The aim of this study was to assess whether animal tuberculosis (TB) is transmitted between free-living European bison (Bison bonasus caucasicus), wild boars (Sus scrofa), and protected carnivores such as grey wolves (Canis lupus), brown bears (Ursus arctos), and Eurasian lynx (Lynx lynx) in the Bieszczady Mountains in Southern Poland. Results of animal studies suggest that TB transmission from bison or wild boars to grey wolves is possible. These are the first described cases where Mycobacterium caprae was detected in samples collected from grey wolves.
