The aim of the study was determination of the frequency of occurrence of Yersinia genus bacteria in surface waters polluted to various degrees with bacteria of the coliform and of fecal coli. For detection of Yersinia rods the previously elaborated medium Endo MLCe and the membrane filter method were applied. Samples of 42 surface waters were examined, including 26 from rivers and 16 from lakes, ponds and clay-pits. On the basis of sanitary bacteriological analysis 16 surface waters were classified to class I purity, 10 to class II, the remaining ones to class III or beyond classification. Yersinia rods were detected in 15 water bodies that is 35.7% of the examined waters. A total of 27 Yersinia strains were identified with dominance of Y. intermedia (14 strains) and Y. enterocolitica (10 strains). Three strains represented by the species Yersinia frederiksenii. Most of the Y. enterocolitica strains belonged to biotype 1, the particular strains being represented by various serotypes. Hence their different origin may be concluded. The pathogenic serotypes 0:3 and 0:9 of Yersinia enterocolitica were not detected.
本研究的目的是确定在被大肠菌群和粪大肠菌群不同程度污染的地表水中耶尔森氏菌属细菌的出现频率。为了检测耶尔森氏菌，采用了先前研制的培养基Endo MLCe和膜过滤法。对42份地表水样本进行了检测，其中包括26份来自河流的样本和16份来自湖泊、池塘及粘土坑的样本。根据卫生细菌学分析，16份地表水被归类为I类纯净度，10份为II类，其余的为III类或超出分类。在15个水体中检测到了耶尔森氏菌，占检测水体的35.7%。共鉴定出27株耶尔森氏菌菌株，其中中间耶尔森氏菌（14株）和小肠结肠炎耶尔森氏菌（10株）占优势。有3株为费氏耶尔森氏菌。大多数小肠结肠炎耶尔森氏菌菌株属于生物型1，个别菌株由不同血清型代表。因此，可以推断它们的来源不同。未检测到小肠结肠炎耶尔森氏菌的致病血清型0:3和0:9。
