  Possible picornavirus in the turquoise (or Lake Kutubu) rainbowfish

Turquoise rainbowfishes (Melanotaenia lacustris) that exhibited whirling symptoms and obvious impairment of the central nervous system were submitted by a breeder for diagnostic evaluation. All were negative for bacterial and parasitic pathogens, Electron microscopy revealed numerous picornavirus particles in the brain. Attempts to grow the virus in cell culture were unsuccessful. No similar cases have been reported since. Picornaviruses have been observed as incidental findings in various freshwater fishes. The significance of their presence is unknown. A similar virus has been found in yabbies in Western Australia with associated mortalities, but the conditions under which disease outbreaks occur are not understood.
