Bdellovibrio was found in all liquid phases of the sewage works examined. The predator was also found in all the river sediments and sewage-polluted river waters examined but could not be found in some unpolluted river waters. Bdellovibrio was able to multiply on the high numbers of bacteria present in the aerobic percolating filter film but could not survive in anaerobic sludge. Similarly, the predator was present in the aerobic surface layers of river sediments but not in the anaerobic bottom layers. The major source of Bdellovibrio in the polluted rivers examined were sewage works effluents, and numbers in both river water and sediment were correlated with river water quality. It was unlikely that Bdellovibrio was important in reducing numbers of other bacteria in either sewage or river sediment.
在所检测的污水处理厂的所有液相中均发现了蛭弧菌。在所有检测的河流沉积物和受污水污染的河水中也发现了这种捕食性细菌，但在一些未受污染的河水中未发现。蛭弧菌能够在好氧渗滤滤膜中大量存在的细菌上繁殖，但无法在厌氧污泥中存活。同样，这种捕食性细菌存在于河流沉积物的好氧表层，而不存在于厌氧底层。在所检测的受污染河流中，蛭弧菌的主要来源是污水处理厂的废水，河水和沉积物中的数量与河流水质相关。蛭弧菌在减少污水或河流沉积物中其他细菌数量方面不太可能起重要作用。
