In a prospective follow-up study conducted in 52 French alpine villages, one weekly water sample was taken in each village provided with untreated ground water and analyzed as to the presence of four indicator bacteria: total plate count, total coliforms, thermotolerant (fecal) coliforms, and fecal streptococci. Cases of acute gastro-intestinal disease (AGID) occurring among 29,272 inhabitants were reported through physicians, pharmacists, and primary school teachers. A loglinear model identified fecal streptococcus (FS) as the best predictor; the presence of fecal coliforms enhanced the effect of FS. The total bacteria count and the total coliforms had no independent contributions. A threshold analysis suggested that any level of indicator bacteria above zero was associated with an excess of AGID.
在一项对法国52个高山村庄进行的前瞻性随访研究中，每周从每个供应未处理地下水的村庄采集一份水样，分析其中四种指示菌的存在情况：总平板计数、总大肠菌群、耐热（粪便）大肠菌群和粪链球菌。通过医生、药剂师和小学教师报告了29272名居民中发生的急性胃肠疾病（AGID）病例。对数线性模型确定粪链球菌（FS）是最佳预测指标；粪便大肠菌群的存在增强了FS的影响。总细菌计数和总大肠菌群没有独立的作用。阈值分析表明，指示菌的任何高于零的水平都与AGID的增加有关。
