ABSTRACT
The present study dealt with the detection of coliforms along with other potential pathogenic bacteria from water bottles of children in the Tarakeswar locality of West Bengal state, India, and exploring their antibiotic susceptibility patterns. A total 6 bacterial isolates were screened from the collected water samples of Hooghly district (West Bengal state, India). Among the 6 isolates, GUW2 and GUW4 and GUW6 were found to be predominant in the feeding bottle water of children and dishwashing water samples. The isolates were either resistant to a single antibiotic: ampicillin or penicillin G, or to both ampicillin and penicillin G. From morphological, biochemical and molecular characterization, GUW2, GUW4 and GUW6 were identified as Alcaligenes sp., Bacillus licheniformis and Escherichia coli respectively. In order to prevent water borne bacterial infections among the people in the study area, regular surveillance for antibiogram of bacteria from drinking water samples is mandatory.
Keywords: Water bacteria, Coliform, Antibiotic, Alcaligenes sp., Bacillus licheniformis, Escherechia coli.
