Interpretive Summary:

Technical Abstract: Weissella ceti, the causative agent of weissellosis, is a significant disease of farmed rainbow trout. Weissellosis was first described in rainbow trout (Oncorhynchus mykiss) in China in 2007 and has since been identified as the causative agent of disease in outbreaks at commercial trout farms in both Brazil and the southeastern United States. The origin of the bacteria associated with these outbreaks is unknown at present, but the occurrence of this pathogen on three continents over the course of 4 years is noteworthy and suggests that W. ceti is a rapidly emerging pathogen of rainbow trout. This book chapter describes the disease caused by W. ceti including information on its geographical range, clinical signs, methods for its diagnosis and methods for its control. The emergence and spread of this novel pathogen poses a threat to rainbow trout culture and thus monitoring for this pathogen has become increasingly important.
