Antibiotic resistant bacteria from commercially marketed fish in Adana, Turkey were investigated. A total of 126 antibiotic resistant bacteria were isolated from gill and intestinal contents of five types of retail fish samples. Viable counts of antibiotic resistant bacteria isolated from gill and intestinal content samples showed high frequencies of resistance to tetracycline, ampicillin, streptomycin, while the proportion of chloramphenicol resistance was rather low. A high incidence of resistance to tetracycline, ampicillin and cephalothin as well as almost an absence of resistance to amikacin and gentamicin was found among selected isolates which represented the resistant bacterial population. These strains were predominantly resistant to 3 and 4 antibacterials. Isolates from gill exhibited resistance to as many as 7 antibiotics, whereas those from intestinal content were resistant to 5 or fewer antibiotics. These results indicate that retail fish studied were either contaminated with handling or commercial fishes residing in waters near the disposals of urban sewage, might play a role as carriers of antibiotic resistant bacteria, prompting a health risk to public health for fish consumers.
