Human fecal pollution of recreational waters remains a public health concern worldwide. As a result, there is a growing interest in the application of human-associated fecal source identification quantitative real-time PCR (qPCR) technologies for water quality research and management. However, there are currently no standardized approaches for field implementation and interpretation of qPCR data. In this study, a standardized HF183/BacR287 qPCR method was combined with a water sampling strategy and a novel Bayesian weighted average approach to establish a human fecal contamination score (HFS) that can be used to prioritize sampling sites for remediation based on measured human waste levels. The HFS was then used to investigate 975 study design scenarios utilizing different combinations of sites with varying sampling intensities (daily to once per week) and number of qPCR replicates per sample (2-14 replicates). Findings demonstrate that site prioritization with HFS is feasible and that both sampling intensity and number of qPCR replicates influence reliability of HFS estimates. The novel data analysis strategy presented here provides a prescribed approach for the implementation and interpretation of human-associated HF183/BacR287 qPCR data with the goal of site prioritization based on human fecal pollution levels. In addition, information is provided for future users to customize study designs for optimal HFS performance.

人类粪便污染评分,用于使用HF183 / BacR287定量实时PCR方法对娱乐场所进行排名。

娱乐水对人类粪便的污染仍然是全球公共卫生关注的问题。结果,人们越来越关注将人类相关的粪便源识别定量实时PCR(qPCR)技术用于水质研究和管理。但是,目前还没有用于现场实施和qPCR数据解释的标准化方法。在这项研究中,将标准的HF183 / BacR287 qPCR方法与水采样策略和新颖的贝叶斯加权平均方法相结合,以建立人类粪便污染评分(HFS),该评分可用于根据测得的人类废物确定采样地点的优先级以进行补救水平。然后,使用HFS来调查975个研究设计方案,这些方案采用了具有不同采样强度(每天至每周一次)和每个样品qPCR重复次数(2-14次重复)的位点的不同组合。结果表明,使用HFS进行位点优先排序是可行的,并且采样强度和qPCR重复次数都会影响HFS估计值的可靠性。此处介绍的新颖数据分析策略为实现和解释与人类相关的HF183 / BacR287 qPCR数据提供了一种规定的方法,其目的是根据人类粪便污染水平对场所进行优先排序。此外,还为将来的用户提供了信息,以定制研究设计以获得最佳的HFS性能。结果表明,使用HFS进行位点优先排序是可行的,并且采样强度和qPCR重复次数都会影响HFS估计值的可靠性。此处介绍的新颖数据分析策略为实现和解释与人类相关的HF183 / BacR287 qPCR数据提供了一种规定的方法,其目的是根据人类粪便污染水平对场所进行优先排序。此外,还为将来的用户提供了信息,以定制研究设计以获得最佳的HFS性能。结果表明,使用HFS进行位点优先排序是可行的,并且采样强度和qPCR重复次数都会影响HFS估计值的可靠性。此处介绍的新颖数据分析策略为实现和解释与人类相关的HF183 / BacR287 qPCR数据提供了一种规定的方法,其目的是根据人类粪便污染水平对场所进行优先排序。此外,还为将来的用户提供了信息,以定制研究设计以获得最佳的HFS性能。此处介绍的新颖数据分析策略为实现和解释与人类相关的HF183 / BacR287 qPCR数据提供了一种规定的方法,其目的是根据人类粪便污染水平对场所进行优先排序。此外,还为将来的用户提供了信息,以定制研究设计以获得最佳的HFS性能。此处介绍的新颖数据分析策略为实现和解释与人类相关的HF183 / BacR287 qPCR数据提供了一种规定的方法,其目的是根据人类粪便污染水平对场所进行优先排序。此外,还为将来的用户提供了信息,以定制研究设计以获得最佳的HFS性能。
