Gordonae and Myc. , 2005). In their excellent review, Kaattari et al. (2006) discuss all the currently recognised mycobacterial fish pathogens, including the new but not formally named species, Myc. "chesapeaki". Nocardiaceae representatives Nocardia spp. , 2000). Symptoms similar to mycobacteriosis develop in affected fish. All age groups may be infected, with lesions, manifested as small white spots, present in the dermis, muscle, gills and internal organs. Noc. seriolae has spread from its initial focal point in Japan, and has, for example, been diagnosed among pond cultured sea bass (Lateolabrax japonicus) in Taiwan.
Hettiarachchi and Cheong (1994) described Aer. hydrophila as the cause of disease in freshwater ornamental fish in Sri Lanka, with disease signs including the presence of eroded fins, haemorrhages on the skin and at the base of the caudal fin, sloughing scales and haemorrhaging in the intestinal wall. Aeromonas salmonicida Historically, Aer. salmonicida was thought to have a predilection for salmonids. Over the years, however, the apparent host range of the pathogen has steadily expanded. Thus, infections are known to occur among representatives of several major families of Osteicthys, including Cyprinidae, Serranidae and Anoplopomatidiae, in addition to the Salmonidae (Herman, 1968), and also the Agnatha (Family Petromyzontidae) (Hall, 1963).
