Abstract

Bacteriological examination of Clarias gariepinus, suffering from ulcerative disease, was carried out. As a whole, 18 species of bacteria viz.,Aeromonas caviae, A hydrophila, A. salmonicida, A. sobria, Bacillus sp., Escherichia coli, Edwardsiella tarda, Plesiomonas shigelloides, Pseudomonas aeruginosa, Pseudomonas sp., Salmonella sp.,Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus sp. and unidentified bacteria were isolated from the fishes having ulcerative disease.

Out of 30 isolates, Aeromonas caviae accounted 3.4%, A. hydrophila 10%, A. salmonicida 3.4%, A. sobria 3.4%, Bacillus sp. 10%, Escherichia coli 3.4%, Edwardsiella tarda 3.4%, Flavobacterium columnare 3.4%, Flavobacterium sp. 3.4%, Micrococcus luteus 3.4%, Plesiomonas shigelloides 3.4%, Pseudomonas aeruginosa l0%, Pseudomonas sp. 6.7%, Salmonella sp. 6.7%, Staphylococcus aureus 3.4%, Staphylococcus epidermidis 6.7%, Streptococcus sp. 6.7% and unidentified bacteria 10%.

Out of 18 species of bacteria,Aeromonas hydrophila, A. salmonicida, A.sobria, Edwardsiella tarda, Flavobacterium columnare, Flavobacterium sp., Micrococcus luteus, Salmonella sp.,
