Great differences in capability to detect bacteriophages from urban sewage of the area of Barcelona existed among 115 strains of Bacteroides fragilis. The capability of six of the strains to detect phages in a variety of feces and wastewater was studied. Strains HSP40 and RYC4023 detected similar numbers of phages in urban sewage and did not detect phages in animal feces. The other four strains detected phages in the feces of different animal species and in wastewater of both human and animal origin. Strain RYC2056 recovered consistently higher counts than the other strains and also detected counts ranging from 10(1) to approximately 10(3) phages per ml in urban sewage from different geographical areas. This strain detected bacteriophages in animal feces even though their relative concentration with respect to the other fecal indicators was significantly lower in wastewater polluted with animal feces than in urban sewage.
在115株脆弱拟杆菌中，从巴塞罗那地区城市污水中检测噬菌体的能力存在很大差异。研究了其中6株菌株在各种粪便和废水中检测噬菌体的能力。菌株HSP40和RYC4023在城市污水中检测到的噬菌体数量相似，而在动物粪便中未检测到噬菌体。其他4株菌株在不同动物物种的粪便以及人和动物来源的废水中均检测到噬菌体。菌株RYC2056 consistently比其他菌株回收的数量更高，并且在来自不同地理区域的城市污水中还检测到每毫升10(1)至约10(3)个噬菌体的数量。即使在被动物粪便污染的废水中，相对于其他粪便指标，动物粪便中噬菌体的相对浓度明显低于城市污水，该菌株仍能在动物粪便中检测到噬菌体。
