ABSTRACT: The redclaw crayfish Cherax quadricarinatus (von Martens, 1868) is one of the most commonly exploited freshwater crayfish species worldwide. Redclaw crayfish are susceptible to a number of pathogens but none have been linked to widespread epizootics. Mycobacterial infections have been sporadically reported in crayfish. In the case described, histopathology and bacterial identification confirmed an opportunistic infection caused by Mycobacterium gordonae in a hatchery of C. quadricarinatus in Israel. Intranuclear inclusion bodies, recorded in cells of the tubular epithelium of the hepatopancreas by histopathology, indicate a co-infection with a viral agent, referable to C. quadricarinatus bacilliform virus (CqBV). To the best of our knowledge this is the first description of mycobacteriosis in redclaw crayfish.
