Comparative Study of the Antibiotic Resistance Exhibited by Fecal Coliforms Obtained from Dighi Talab and Bisar Talab of Gaya, Bihar (India)

The antibiotic resistance pattern of four types of fecal coliform bacteria obtained from two fresh water ponds of Gaya was examined during present research work. Data obtained showed that cent per cent of the total isolates (83) of E. coli obtained from water sample of Dighi Talab showed resistance against Ampicillin as well as 83.13%, 71.08%, 69.88% and 32.53% remained resistant against Erythromycin, Gentamycin, Tetracycline and Chloramphenicol respectively. Cent per cent of the total isolates (27) of K. pneumoniae obtained from the water sample of this pond remained resistant against Tetracycline as well as 96.30%, 92.59%, 25.93% and 18.52% of total isolates showed resistance against Erythromycin, Ampicillin, Chloramphenicol and Gentamycin respectively. Out of the total (26) isolates of P. aeruginosa obtained from water sample of this pond 96.15%, 88.46%, 80.77%, 58.55% and 34.62% exhibited resistance against Tetracycline, Amplicillin, Erythromycin, Gentamycin and Chloramphenicol respectively. Cent per cent of the total isolates (06) of Sammonella sp. obtained from the water of this pond remained resistant against Teracycline as well as 83.33% remained resistant against Amplicillin, Gentamycin and Chloramphenicol. Only 66.67% of Salmonella sp. obtained from this pond remained resistant against Enthromycin. Out of the total (40) isolates of E. coli obtained from water sample of Bisar Talab, 97.50%, 95%, 87.50%, 75% and 60% showed resistance against Amplicillin, Tetracycline, Erythromycin, Gentamycin and Chloramphenicol respectively. Whereas, out of the total (36) isolates of K. pneumoniae obtained from this pond, cent per cent exhibited resistance against Amplicllin and Gentamycin. But 91.67%, 83.33% and 19.44% of the total isolates of this bacteria obtained from this pond and tested during present research work exhibited resistance against Tetracycline, Erythromycin and Chloramphenicol respectively. Out of the total (27) isolates of P. aeruginosa obtained from water of this pond, 24,22,17 and 13 exhibited resistance against Amplicillin & Tetracycline, Erythromycin, Chloramphenicol and Gentamycin respectively. Only two isolates of Salmonella sp. were obtained from the water sample of this pond, out of which one remained resistant against Gentamycin and Chloramphenicol whereas both remained resistant against. Amplicillin, Erythrimycin and Tetracyline. The main cause of antibiotic resistance exhibited by different bacterial isolates should be examined by future research.
