在这项研究中，通过监测澳大利亚昆士兰州东南部 (SEQ) 24 个家庭的大肠杆菌和肠球菌数量，评估了雨水箱供水的家庭自来水样本的微生物质量。定量 PCR (qPCR) 还用于定量检测雨水箱和连接的家用水龙头的水样中的人畜共患病原体。由于负鼠和鸟类被认为是屋顶收集的雨水 (RHRW) 中粪便污染的潜在来源，因此还使用 qPCR 估算了负鼠和各种鸟类粪便样本中的人畜共患病原体数量。在24户家庭中，63%的雨水箱和58%的连接家庭自来水（CHTW）样本含有大肠杆菌，超出了澳大利亚饮用水指南
In this study, the microbiological quality of household tap water samples fed from rainwater tanks was assessed by monitoring the numbers of Escherichia coli bacteria and enterococci from 24 households in Southeast Queensland (SEQ), Australia. Quantitative PCR (qPCR) was also used for the quantitative detection of zoonotic pathogens in water samples from rainwater tanks and connected household taps. The numbers of zoonotic pathogens were also estimated in fecal samples from possums and various species of birds by using qPCR, as possums and birds are considered to be the potential sources of fecal contamination in roof-harvested rainwater (RHRW). Among the 24 households, 63% of rainwater tank and 58% of connected household tap water (CHTW) samples contained E. coli and exceeded Australian drinking water guidelines of
