Antibiotic sensitivity test against Vibrio sp. isolated from Rameswaram
Island
Abstract :
A high mortality with symptoms such as external black patches on the body and anorexic conditions were noted among laboratory-cultured seahorse, Hippocampus kuda in Vizhinjam research unit in south west coast of India. Bacteria isolated from internal organs of infected animals were biochemically homogenized and identified as Vibrio harveyi. When infectivity of the isolated bacteria was studied in tilapia Oreochromis mossambicus, symptoms such as tail rot and erythema were noted apart from the blackening of skin. The lethal dose for tilapia with average body weight of 6.6g was 2.5 x 106 cells/fish, while for the seahorse with an average body weight of 4.41g, it was 4 x 104 cells/fish
