A comparative study on the occurrence of pathogens in urban waters
In order to know the occurrence of pathogens and their relationships with indicator bacteria in urban waters, the representative waters including source of drinking water supply and recreational water were investigated on the presence of pathogens by the real-time PCR method developed in this study. Compared with fecal coliform count, the relationships between various pathogens and fecal coliform were analyzed through one year period of monitoring. The results of statistical analysis showed that the concentrations of enteroviruses and other pathogenic bacteria in each water body all followed the log-normal distribution. No significant correlation between enteroviruses and fecal coliform was observed in urban waters. The relationship between Escherichia coli and fecal coliform related to the degree of fecal pollution in urban waters. When fecal coliform concentration was more than 104CFU/L, it might appear more Salmonella typhi in waters. Shigella might be detected in the waters with low concentration of coliform. There was significant correlation between Shigella and Escherichia coli in serious polluted waters. Count of fecal coliform can not reflect overall the sanitary quality of urban waters.
