Microbiological and chemical analysis of drinking water in southern India (with special consideration of Aeromonas species).

Abstract

Analyses of drinking water taken from central and individual water supplies in Southern India (Idukki/Kerala) showed bacterial counts of 10(3)-10(6). E. coli were found in 11% and 28% of the samples. Aeromonads were identified more frequently than E. coli at 44% in central and 38% in individual water supplies. Due to this high rate of contamination, Aeromonas spp. must be considered as a possible cause of diarrhoea and other infections in this area.
