Groundwater is thought to be free of microbial contamination due to the natural filtering ability of the subsurface environment. The study is undertaken to investigate the presence pathogenic bacteria and their antimicrobial resistance pattern of groundwater of Sitakunda, Chittagong. In this study bacterial contamination in tube well water has been analyzed in terms of coliform, fecal coliform and vibrio. Qualitative analysis of bacteria is performed by spread plate technique and antibiotic susceptibility test is done by disk diffusion method. In bacteriological analysis total coliform, total fecal coliform, and total vibrio spp. count are ranged from 0.65⇥102 to 2.0⇥102 cfu/ml, 0.10⇥102 to 2.20⇥102cfu/ml and 0.0 to 0.55⇥102cfu/ml, respectively. All of the coliform isolates are resistant to ampicillin, all fecal coliform isolates to penicillin and sulphamethoxazole and vibrio spp. are resistance to erythromycin and azithromycine. The coliform isolates also display multidrug resistance. The resulting contamination of tube well water with pathogen and their resistivity to antibiotic is an alarming threat to public health, so tube well water of Sitakunda, Chittagong must be treated prior to drinks.
