Abstract
An intragastric inoculation of approx. 2 × 1010 Yersinia enterocolitica cells killed chinchillas in three days in the case of four strains out of six tested. Because of the sensitivity of chinchillas to this bacterium, the test is useful for the evaluation of the virulence and invasiveness of Y. enterocolitica isolates. This animal model could also be used for studies on the mechanism of the infection.
Sammanfattning
Av sex testade Yersinia enterocolitica stammar dödade fyra stammar chinchillor inom tre dagar efter en i magsäcken utförd inympning av ungefär 2 × 1010 celler. På grund av detta djurlags känslighet för Y. enterocolitica är detta test användbar för att bestämma virulensen och invasionsförmagan hos en isolat. Denna djurmodell kan också användas för att undersöka infektionsmekanismen.
