Abstract：
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.
摘要：
在孟加拉国等发展中国家，与水有关的疾病引起了极大的关注。每年,许多人死于饮用不安全的饮用水。为了保护公众健康，强制性的饮用水应达到最高质量。在这项描述性观察研究中，从不同的商店和餐馆收集了150个瓶装水样品和150个罐子水样品。将每个样品通过膜滤器过滤,然后置于MacConkey琼脂培养基上用于总和粪便大肠杆菌计数,并将0.1ml水涂布在营养琼脂培养基上用于异养平板计数(HPC)。在150个瓶装水样品中，有11个（7.33％）是培养阳性，在150个罐水样中92个（61.33％）是培养阳性。在150个罐水样品中，有38个（25.33％）是总大肠杆菌，其中19个（12.67％）是粪便大肠杆菌。在300个水样品中,55个(53.40%)样品显示HPC大于500CFU/ml。共有9种细菌分离物：大肠杆菌，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。发现了柠檬酸杆菌.
