The main reservoirs of the bacterium are herbivores, which harbour the bacteria in their bowels (with no consequences for them) and disseminate the “spore form ” of the bacteria in the environment with their faeces.
Bakter esineb põhiliselt mäletsejate sooles (ilma haigusnähtudeta), levides sealt spooridena väljaheidete kaudu väliskeskkonda.
