Abstract
The incidence and antibiotic rqsistance pattern of E. croli and Saltrll.:lwlla from water, beach sand and fish collected from four fish Ianding centres of Thoothuktrdi were studied. Presence of E. coli was confirmed in 90%, 92./. and 797o of watet beach sand and fish samples .respectively, while Salnronclla was detected in 25% of water and sand samples and 77Yo of fish samples. The isolates rl'ere tested against fifteen antibiotics by disc diffusion method. tlfi.le ;jl ihe 5 .lll: isolates r\'ere resistant to bacikacin, erythromycin and rifampicin, none of the isolates was resistant to ampicillin, chloramphenicol and sulphafurazole Among Saln,tonella isolates, all were resistant to bacitracin and most were resistant to ampicillin, colibtin, erythromycin and rifampicin. None of the Salnronella isolates was resistant to bhl6ramphenicol, ciprofloxacin and norfloxacin. Muliiple antibiotic resistance (MAR) index was higher than 0.2 in all strains of E. coli arrd Salmonelln revealing that they might have orlgihated from high-risk sources of contamination such as humans.
