The influence of cultivation temperature on some phenotypic traits of Yersinia pseudotuberculosis
Introduction. Some causative agents of saprozoonotic infections can multiply in the external environment (water reservoirs, soils, plants), as well as in animals, including microorganisms of the genus Yersinia. Material and methods. Isolation and identification of Y. pseudotuberculosis was carried...
