Using a modified cold enrichment procedure Yersinia spp. were detected in 90.6% out of 32 raw waste water samples obtained within one year from two municipal sewage treatment plants. Moreover Yersinia were isolated from 50% of 6 effluent samples. Altogether 118 Yersinia strains were isolated and typed biochemically and serologically. 69 out of these isolates belonged to Yersinia enterocolitica, 60 strains to biotype 1, and 9 to biotype 4, serotype 0:3, 8 strains Yersinia enterocolitica serotype 0:3, biotype 4, considered to be a causative agent in human enteritis, harboured an 48 MD plasmid. The remaining isolates were identified as Yersinia frederiksenii (24 strains), Yersinia intermedia (22 strains) and Yersinia kristensenii (3 strains). The frequency of the isolation of Y. enterocolitica serotype 0:3, biotype 4 from sewage showed the same seasonal dependence as known from strains of human origin. In contrast to this, such dependence could not be found among other serovars of Y. enterocolitica and related species.
采用改良的冷富集程序，在一年内从两个城市污水处理厂采集的32份原废水样本中，90.6%检测到耶尔森菌属。此外，在6份出水样本中，50%分离出了耶尔森菌。总共分离出118株耶尔森菌，并进行了生化和血清学分型。其中69株属于小肠结肠炎耶尔森菌，60株为生物型1，9株为生物型4、血清型0:3；8株小肠结肠炎耶尔森菌血清型0:3、生物型4，被认为是人类肠炎的病原体，携带一个48 MD质粒。其余分离株鉴定为费氏耶尔森菌（24株）、中间耶尔森菌（22株）和克氏耶尔森菌（3株）。从污水中分离出的小肠结肠炎耶尔森菌血清型0:3、生物型4的频率与来自人类来源的菌株显示出相同的季节依赖性。与此相反，在小肠结肠炎耶尔森菌的其他血清型和相关物种中未发现这种依赖性。
