yersiniosis

septicemia often with signs of gastroenteritis, caused by Yersinia pseudotuberculosis, occurring in wild rodents, birds, and, uncommonly, most domestic species, particularly cats. There is fever, severe toxemia and a high fatality rate. At postmortem there are large numbers of embolic abscesses in most organs. Called also pseudotuberculosis.

Occurs also in many species of fish as a septicemia, caused by Yersinia ruckeri.
