Adherence of Escherichia coli in pathogenesis of endometritis and effects of estradiol examined by scanning electron microscopy

Abstract

Escherichia coli was inoculated into the uterine lumen of ovariectomized rats, and the endometrial surfaces were examined by scanning electron microscopy. Adherence of E. coli to the epithelium and destruction of the surface leading to purulent endometritis were noticed. When rats were treated previously with estradiol, adherence of E. coli was not detected.
