Abstract

Potential virulence, as defined by combined levels of adhesion to urinary epithelial cells, serum resistance, and mouse toxicity, was assessed for Escherichia coli strains causing symptomatic and asymptomatic urinary tract infections in relation to the carriage of hemolysin and other suspected virulence determinants. Hemolysin production (Hly), associated with certain O (O4, O6, O18, and O75), K (5), and hemagglutination (VI and VII) antigenic types but not colicin V production (Cva), was evident in 83 and 60% of isolates in groups possessing high potential virulence and in only 11 and 6% of those with low virulence. Strains of particular O-types were not more virulent per se, but among the serotypes, specific combinations of virulence factors appeared decisive, e.g., O18 HAVI B/D/G Hly(+) K5(+/-) and O18 HAIII/IVB/V Hly(-) Cva(+/-) K1(+/-) strains were, respectively, of high and low potential virulence. Isolates with high potential virulence were found to a similar extent in symptomatic and asymptomatic infections.

摘要

通过对尿路致病性大肠埃希菌菌株与溶血素及其他可疑毒力决定因素携带情况的分析，评估了这些菌株对尿路上皮细胞的黏附、血清抗性和小鼠毒性综合水平所定义的潜在毒力。溶血素产生（Hly）与某些O（O4、O6、O18和O75）、K（5）以及血凝（VI和VII）抗原类型相关，但与产大肠杆菌素V（Cva）无关，在高潜在毒力组的83%和60%的分离株中明显可见，而在低毒力组中仅为11%和6%。特定O型菌株本身并非更具毒力，但在血清型中，毒力因子的特定组合似乎起决定性作用，例如，O18 HAVI B/D/G Hly(+) K5(+/-)和O18 HAIII/IVB/V Hly(-) Cva(+/-) K1(+/-)菌株分别具有高和低潜在毒力。在有症状和无症状感染中发现具有高潜在毒力的分离株的比例相似。
