| Abstract: | Sensitivity of 175 isolates of luminous bacteria from various shrimp farming systems of West Bengal was tested against six antibiotics, viz., chloramphenicol (30µg), ciprofloxacin (5µg), co-trimoxazole (25µg), gentamycin (10µg), nitrofurantoin (300µg) and oxytetracycline (30µg). Besides, the minimum inhibitory concentration (MIC) of the antibiotics was determined against 60 isolates of Vibrio harveyi. The isolates were least susceptible to oxytetracycline followed by ciprofloxacin and nirofurantoin, and highly susceptible to chloramphenicol. Vibrio harveyi was the most resistant species. About 56% of the luminous isolates exhibited multiple antibiotic resistance. The MIC of oxytetracycline was observed to be in the range of 1.56->200 µg/ml. Majority of the isolates were inhibited at a concentration of 0.10-0.78 µg/ml of ciprofloxacin and 0.20-6.25 µg/ml of chloramphenicol. The observations on the antibiotic resistance did not indicate that the luminous bacteria of certain shrimp culture systems of West Bengal is developing resistance to broad-spectrum antibiotics. |
