The distribution of resistance to ampicillin, chloramphenicol, sulfonamides, tetracycline, and streptomycin among fecal coliforms in sewage, surface waters, and sea water was investigated. The incidence of resistant strains among isolates varied significantly among the water samples, without obvious connection with the water source or the level of pollution. The average frequency of multiple resistance was not always high in the same samples in which the overall resistance was high. The species composition varied considerably in different water samples. A significant correlation was observed between the relative frequency of Klebsiella species and the incidence of ampicillin resistance in water samples. The importance of species composition of fecal coliforms, affected by their source and by the aquatic environment, on the resistance pattern is noted.
对污水、地表水和海水中粪大肠菌群对氨苄青霉素、氯霉素、磺胺类药物、四环素和链霉素的耐药性分布进行了调查。在不同水样中，分离菌株中的耐药菌株发生率差异显著，与水源或污染程度无明显关联。在总体耐药性高的相同样本中，多重耐药的平均频率并不总是很高。不同水样中的物种组成差异很大。在水样中观察到克雷伯菌属的相对频率与氨苄青霉素耐药性发生率之间存在显著相关性。注意到受粪便大肠菌群来源和水生环境影响的物种组成对耐药模式的重要性。
