- Abstract
An investigation was carried out focusing on the characterization of bacterial spp. in the commercially available drinking water of Bangladesh. This study was conducted to characterize the bacteria species in cultural, biochemical, pathogenic, and antibiotic sensitivity analyses. A total of 50 commercial bottled water samples from 10 manufacturing companies were collected from the market. Out of these 50 samples, 4 (8%) were found to be positive for Staphylococcus aureus. All isolates fermented glucose, maltose, mannitol, lactose, and sucrose with the production of acid but did not ferment salicin, raffinose, or inulin. On the other hand, these isolates showed that the indole test was negative but the Voges-Proskauer test and the methyl-red test were positive. All these isolates were coagulase positive and pathogenic to mice. All isolates were highly sensitive to enrofloxacin and norfloxacin, moderately sensitive to ciprofloxacin and ampicillin, less sensitive to pefloxacin, and resistant to furazolidon. Based on the present study it might be concluded that the investigated bacteria species may be Staphylococcus aureus. This is a preliminary report focusing on the public health importance and further characterization using serological and molecular techniques is, therefore, required.
