[Exoenzymes of Yersinia pseudotuberculosis]

Pseudotuberculous microbe produced (in natural medium, at 10-14 degrees) toxins and exoenzymes, pathogenic effect of which was studied in experimental conditions. After invasion of pseudotuberculous microbe into macroorganism its populations appear to change, as a result of this activities of neuraminidase and hyaluronidase were increased. Cultivation of pseudotuberculosis bacteria in vivo may serve as a promising model for studies of enzymatic mechanisms of pathogenesis.
