一些新西兰地区委员会正在研究使用粪便链球菌（或亚群，肠球菌），以协助确定污染源，或作为更好的指标，疾病的风险比粪便大肠菌群在洗澡沃茨。然而，尽管在世界范围内进行了调查，但粪便链球菌在很大程度上未能发挥其作为受纳沃茨污染源（人类与动物）指标的潜力。使用粪大肠菌群：粪链球菌（FC：FS）比例时伴随着许多鉴定，种属鉴定方法（使用生物化学和基于DNA的方法）产生了不确定的结果。然而，FC：FS移位方法（其中比率在样品储存下变化）可能需要进一步研究。尽管报告的结果差异很大，但大多数研究表明，粪便链球菌在接收沃茨中的寿命比粪便大肠菌群长，并且对阳光诱导的灭活更具抵抗力。美国环保局的流行病学研究表明，肠球菌浓度...
Abstract Some New Zealand regional councils are examining the use of faecal streptococci (or the subset, enterococci) to assist in identifying pollution sources, or as better indicators of disease risk in bathing waters than faecal coliforms. However, in spite of worldwide investigation, faecal streptococci have largely failed to fulfil their potential as pollution source (human versus animal) indicators in receiving waters. Many qualifications accompany the use of faecal coliform: faecal streptococci (FC: FS) ratios, and the species identification approach (using biochemical and DNA‐based methods) has produced inconclusive results. Nevertheless, the FC: FS shift method (in which the ratio changes under sample storage) may warrant further investigation. Although reported results vary widely, most studies indicate that faecal streptococci outlive faecal coliforms in receiving waters and are more resistant to sunlight‐induced inactivation. USEPA epidemiological studies showed that enterococcus concentration...
