[Hemorrhagic septicemia in rainbow trout due to Yersinia ruckeri sp. nov].
Bacterial hemorrhagic septicemia in rainbow trout is reported for the first time in this country, with Yersinia ruckeri as causative agent. The identification of the isolated strains was carried out on the basis of morphologic, cultural, and biochemical properties. Described are the morphologic changes, giving some epizootiologic data. Stated is the employment of an immunochemical method for differential diagnosis, based on changes that take place in the plasmal lipoproteins of diseased trouts. It has been found that the immunoelectrophoresis of sera of trouts infected with Yersinia ruckeri, using rabbit antisera against trout plasmal proteins reveals only traces of the molecularly destroyed alfa- and beta-lipoproteins.
