Surface waters along the Kalamazoo River, USA, were examined for occurrence and population trends of fecal indicator bacteria (FIB) with culture-based and culture-independent methods. The two methods recorded discrepancies in FIB counts, with the culture-independent method revealing more consistent numbers between the river sites. FIB cells that hybridized with the ECO1482 probe were highest in the downstream site, while the upstream site recorded higher ENF343 hybridized cells. Spatial and temporal differences in FIB populations were probably attributable to contrasting fecal pollution influences, vegetation type, varying environmental conditions as well as several in-stream factors between the two river sites.
美国卡拉马祖河沿岸的地表水通过基于培养和非培养的方法检测粪便指示菌 (FIB) 的出现和种群趋势。这两种方法记录的 FIB 计数存在差异，非培养方法在河流水体之间揭示了更一致的数量。与 ECO1482 探针杂交的 FIB 细胞在下游位点最高，而上游位点记录的 ENF343 杂交细胞更高。FIB 种群的时空差异可能归因于两个河流水体之间不同的粪便污染影响、植被类型、不断变化的环境条件以及几种溪流内因素。
