Water related diseases are of great concern in developing countries like Bangladesh. Every year, many people die due to consumption of unsafe drinking water. In order to protect public health it is compulsory that the accessible drinking water should be maximum quality. In this descriptive observational study 150 samples of bottled water and 150 jar water samples were collected from different shops and restaurants. Each sample were filtered through a membrane filter and then placed on MacConkey agar media for total and fecal coliform count and 0.1 ml of water spread on nutrient agar media for heterotrophic plate count (HPC). Among 150 bottled water samples 11 (7.33%) were culture positive and 92 (61.33%) were culture positive in 150 jar water samples. Out of 150 jar water samples 38 (25.33%) were total coliform and among them 19 (12.67%) were fecal coliform. Among 300 water samples 55 (53.40%) samples showed HPC greater than 500 CFU/ml. A total of 9 bacterial isolates: Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Acinetobacter spp. CONS, Aeromonas spp., Enterobacter spp., Klebsiella spp. and Citrobacter were found.
在孟加拉国等发展中国家，与水有关的疾病令人十分关注。每年都有许多人因饮用不安全的饮用水而死亡。为了保护公众健康，可获得的饮用水必须达到最高质量标准。在这项描述性观察研究中，从不同的商店和餐馆采集了 150 个瓶装水样本和 150 个罐瓶水样本。每个样本都经过膜过滤器过滤，然后放置在麦康凯琼脂培养基上进行总大肠菌群和粪大肠菌群计数，将 0.1ml 的水散布在营养琼脂培养基上进行异养平板计数（HPC）。在 150 个瓶装水样本中，有 11 个（7.33%）呈培养阳性，在 150 个罐瓶水样本中，有 92 个（61.33%）呈培养阳性。在 150 个罐瓶水样本中，有 38 个（25.33%）总大肠菌群呈阳性，其中 19 个（12.67%）为粪大肠菌群。在 300 个水样中，有 55 个（53.40%）水样的 HPC 大于 500CFU/ml。共发现 9 株细菌分离株：大肠埃希氏菌、金黄色葡萄球菌、铜绿假单胞菌、不动杆菌属 CONS、气单胞菌属、肠杆菌属、克雷伯菌属和柠檬酸杆菌。
