Abstract: Use of antibiotics in fishponds may increase occurrence of antibiotic-resistant bacteria thereby posing public health risk. The aim of this study was to determine the occurrence and antibiogram of chloramphenicol-resistant bacteria from fishponds in some communities within Obio/Akpor Local Government Area of Nigeria. Water samples were collected from selected fishponds, and inquiry made into the means of treatment of the sampled fishponds. Samples were analyzed for total heterotrophic bacteria (THB) and Chloramphenicol-resistant bacteria (CRB) using standard methods. Percentage occurrences of CRB in the fishponds were determined, and the CRB were identified through morphological/biochemical means. Identified CRB were subjected to antibiotic susceptibility testing. The results obtained revealed that antibiotics were used in treatment of 64% of the fishponds sampled. THB ranged from 1.33±1.87×1010 to 3.11±0.91×1014 CFU/ml; CRB population ranged from 4.88±4.92 × 102 to 3.32±7.26 × 106 CFU/ml; the occurrence of CRB ranged from 4.83±4.80×10-10 to 0.12±0.29%. Correlation between occurrence of CRB and percentage of fishponds treated with antibiotics (FPAB) showed that there was no correlation between them (r = 0.2). The identified CRB included Vibrio vulnificus, Pseudomonas spp., Staphylococcus spp., Bacillus spp., Macrococcus lamae, Streptococcus spp., Neisseria animaloris, Shimwellia pseudoproteus, Serratia spp., and Proteus hauseri. Among these, Shimwellia pseudoproteus was the most resistant CRB, and most of the CRB were more sensitive to Gentamicin. It is concluded that the presence of antibiotic-resistant bacteria in fishponds may not be due to the use of antibiotics in fishponds, and Gentamicin could be a drug of choice for treatment of infections caused by antibiotic-resistant bacteria.
