摘要：

We used a gentamicin protection assay to assess the ability of gestational pyelonephritis isolates of Escherichia call to invade HeLa cells. The ability to enter HeLa cells was strongly associated with the presence of Dr operons coding for Dr adhesins, In contrast, the nonivasive isolates predominantly expressed papG, coding for P fimbriae.
