[Finding of the bacterial species Edwardsiella tarda in the aquarium fish Betta splendens].
A case of the mass occurrence of a disease in the aquarium fish species Betta splendens is described; morphologically the disease was characterized by the finding of large dermal changes located mainly in the dorsal part and by miliary granulomata in liver, spleen and kidneys. The granulomata consisted of epitheloid light cells with centrally located necrosis. Gram-negative bacteria with morphological and biochemical characteristics corresponding to the bacterial species Edwardsiella tarda were isolated from the kidneys, liver and from the dermal lesion. The characteristics of the strains isolated by us were compared with the reference Edwardsiella strain (Bth 1/64) obtained from the Czechoslovak collection of type cultures, Prague.
