Diarrhoea is one of the leading causes of mortality and morbidity, especially in children of developing countries ( 2) and claims two million lives each year ( 3). Water and food contaminated with bacteria, viruses, and protozoa cause infectious diarrhoea. Approximately a billion people lack access to safe drinking-water ( 1). Providing safe drinking-water to the majority of the world's population, especially to those in developing countries, is still a major problem. Copper holds promise as a point-of-use solution for microbial purification of drinking-water, especially in developing countries. Copper content (177☑6 ppb) in water stored in copper pots was well within the permissible limits of the World Health Organization. After 16 hours, there was a slight increase in the pH of water from 7.83 to 7.93 in the copper pots while the other physicochemical parameters remained unchanged. This is the first report on the effect of copper on S. Recovery failed even after resuscitation in enrichment broth, followed by plating on selective media, indicating loss of culturability. When drinking-water (pH 7.83☐.4 source: ground) was contaminated with 500 CFU/mL of the above bacteria and stored in copper pots for 16 hours at room temperature, no bacteria could be recovered on the culture medium. coli, Salmonella enterica Typhi, and Salmonella Paratyphi is reported. The antibacterial effect of copper pot against important diarrhoeagenic bacteria, including Vibrio cholerae O1, Shigella flexneri 2a, enterotoxigenic Escherichia coli, enteropathogenic E. Therefore, the objective of this study was to evaluate the effect of copper pot on microbially-contaminated drinking-water. Ayurveda recommends the use of copper for storing drinking-water. Although many water-purification methods exist, these are expensive and beyond the reach of many people, especially in rural areas. Microbially-unsafe water is still a major concern in most developing countries.
