摘要 通过水传播的感染是发展中国家传染病的最常见原因，通常是由于缺乏受保护的供水、供水系统故障或污水处理不当造成的。最近对迈索尔市钻井的107个样本的研究表明，51个样本(47.66%)的硝酸盐含量超过45 ppm，这表明这些水对饮用水有害。在使用硫化氢试纸检测粪便污染的51个样本中，有37个样本变黑，这些样本接受了微生物鉴定。从37份样品中分离出63株硫化氢产生菌，其中产硫化氢细菌分别为臭氧克雷伯氏菌、肺炎克雷伯氏菌、奇异变形杆菌、普通变形杆菌、沙门氏菌。和弗劳迪柠檬酸杆菌。
上述6种微生物菌株的出现频率如下：奇异变形杆菌19株；普通变形杆菌14株；弗劳迪柠檬酸杆菌13株；沙门氏菌属。(8)；肺炎克雷伯氏菌(5)；臭氧克雷伯氏菌(4)。已知克雷伯氏菌和变形杆菌可引起尿路感染和沙门氏菌肠道感染。
Abstract Water-borne infections are the most common causes of infectious diseases in developing countries, often resulting from the lack of a protected water supply, a faulty water-supply system or improper sewage disposal. A recent study of 107 samples from bore wells of Mysore city has revealed that 51 samples (47.66%) contain Nitrate greater than 45 ppm, an indication that the water would be harmful for drinking. Out of 51 samples tested for faecal pollution, using a H2S-strip test, 37 samples turned black and these were subjected to microbial identification. Out of these 37 samples, 63 H2S producing strains were isolated and the H2S producing organisms are Klebsiella ozaene;Klebsiella pneumoniae;Proteus mirabilis;Proteus vulgaris;Salmonella sp. and Citrobacter freundi.
The frequency of occurrence of the above-mentioned six micro-organism strains are as follows: Proteus mirabilis (19);Proteus vulgaris (14);Citrobacter freundi (13);Salmonella sp. (8);Klebsiella pneumoniae (5); and Klebsiella ozaene (4). Klebsiella and Proteus are known to cause urinary infection and Salmonella intestional infection.
