Abstract

ABSTRACT: The current investigation was carried out to determine the antibiotic-resistance status of bacteria isolated from Ponnani estuary. Antibiotic sensitivity was determined by the disc diffusion method. A total of 39 samples were collected from three stations of the estuary. Of the fifty-one bacteria isolated, 56.8% were gram-negative, and 43.1% were gram-positive. Vibrio sp. 13(25.49%) Pseudomonas sp. 1(1.9%) Flavobacterium sp. 3(5.9%) E. coli 6 (11.7%) Alcaligenes 6 (11.7) Staphylococcus sp. 21(41.7) and Micrococcus sp. 1 (1.9) were isolated from varies part of the bay. Members of Vibrio sp. are found to be resistant to 8 of the 10 antibiotics employed whereas Flavobacterium sp. and Alcaligens sp. showed resistance to 7 antibiotics used. All members of Vibrio sp. showed resistance to cefoxitin, and cefuroxime while only 76.9% showed resistance to nalidixic Acid. All the members of E. coli were resistant to ampicillin and tetracycline. All the members of the gram-positive bacteria were resistant to methicillin while 95% of them were resistant to nalidixic acid followed by penicillin (86%) and erythromycin(68%). The antibiotics vancomycin and chloramphenicol seems to be highly sensitive to gram-positive isolates. In the current investigation, we found a MAR index of 0.1 to 0.7 among gram-negative bacteria and an index of 0.2 to 0.5 among gram-positive bacteria.
