Description 151-156
Pathogenic
bacterium was isolated from infected parts of the captive reared seahorse.
During the present investigation, high mortality with symptoms such as external
white patches on the body and anorexic conditions were noted among
laboratory-cultured seahorses, Hippocampus
kuda. Bacteria isolated from internal organs of infected fish were
biochemical homogenized and identified as Vibrio
harvei. In infectivity studies with Tilapia, Oreochromis mossambicus, symptoms such as tail rot and erythemia
were noted apart from the white skin. The lethal dose for Tilapia with average
body weight of
8.8g was 8 × 106 cells/fish, while for seahorse with an average body
weight of 6.2 g, it was 4×104 cells/fish.
