Novel Molecular Markers for the Historical Source Tracing of Faecal Contamination in Urban Water Catchments

保护原水系统的微生物质量对于维护饮用水安全至关重要。监测水样中是否存在表明存在粪便污染的微生物，可以用来评估对人类健康的可能威胁。这项研究的目的是应用分子遗传学方法来确定它们作为追踪和追踪饮用水集水区内粪便细菌的工具的有效性。我们选择了芽胞前产气荚膜梭菌作为长期和短期污水污染的指标。这将使我们能够预测污染的来源，从而确定需要补救的粪便污染的潜在来源。

Protection of the microbiological quality of raw water systems is imperative to maintaining the safety of drinking water. Monitoring of water samples for the presence of microbes that indicate the presence of faecal pollution can be used to assess the possible threats to human health. The objective of this research is to apply molecular genetic methods to determine their effectiveness as tools for the tracking and tracing of faecal bacteria within drinking water catchments. We have chosen the spore-former Clostridium perfringens as an indicator of both long and short-term sewage contamination. It will enable us to predict the origin of contamination and thus identify potential sources of faecal pollution that require remediation.
