This study was conducted to investigate bacteria that infected the broodstocks of African catfish cultured at Manir River, Terengganu as well as their antibiogram and Multiple Antibiotic Resistance （MAR） index. In the present study, antibiotic sensitivity and intermediary case were reported as 52.7% and 7.8%, respectively. Meanwhile, antibiotic case was recorded as 34.5%. The MAR index values obtained by each bacterial species was ranging from 0.24 to 0.52 whereas the average MAR index value was 0.39 which indicated that the cultured fish has been highly exposed to tested antibiotics.展开更多
