ABSTRACT

Bacterial coldwater disease and other infections caused by Flavobacterium psychrophilum are a worldwide concern, particularly for freshwater salmonid hatcheries. F. psychrophilum infections can be difficult to control; antibiotic resistance is common and no effective vaccines are currently available. This review summarizes the biology and characteristics of this important pathogen, as well as the techniques required for isolation and identification. In addition, the epidemiology, clinical signs, treatment, and possible preventative measures of bacterial coldwater disease are discussed.
