Of 23 unique Escherichia coli strains from 10 men with febrile urinary tract infections (UTIs) and their female sex partners, 6 strains (all UTI causing) were shared between partners. Molecularly, the 6 shared strains appeared more virulent than the 17 nonshared strains, being associated with phylogenetic group B2, sequence types ST73 and ST127, and multiple specific virulence genes. This indicates that UTIs are sometimes sexually transmitted.
在从10名患有发热性尿路感染(UTI)的男性及其女性性伴侣身上分离出的23株独特大肠杆菌菌株中,有6株(均导致UTI)在伴侣之间是相同的。从分子层面来看,这6株相同的菌株似乎比17株不同的菌株更具毒性,它们与系统发育组B2、序列类型ST73和ST127以及多个特定毒力基因相关。这表明尿路感染有时是性传播的。
