Abstract

A study on the antibiogram of Catfish from the Lake Kainji area of Nigeria was conducted. A total of forty (40) fish samples were used for this study. Bacterial cultures obtained from the skin of twenty Clarias anguillaris and twenty Heterobranchus bidorsalis were subjected to microbial analysis. The antibiotic sensitivity tests using seven antibiotics revealed that all the five isolates viz: Pseudomonas aeroginosa, Aeromonas aureus, Bacillus firmus, Klebsiella aerogines, and Streptococcus iniae were only sensitive to clofuraxine and conflux. Aeromonas aureus and Pseudomonas aeroginosa were sensitive to streptomycin, while Streptococcus iniae was less sensitive to streptomycin, but sensitive to conflux and neocloxin. Streptococcus faciaus and Bacillusfirmus were sensitive to neocloxin while all were resistant to oxytetracycline. Hence clofuraxin and conflux could be recommended for the treatment of fish diseases associated with these microorganisms due to their antimicrobial activity in this study.
