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); Citro-bacter 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.
