An unusual pathologic finding consisting of large colonies of bacteria, localized immediately beneath the epithelial layer of the amnion, has been observed in association with an example of group B beta-hemolytic streptococcal chorioamnionitis. Postpartum endometritis as well as neonatal sepsis and meningitis occurred. Histologic examination of the umbilical cord and placenta revealed routine features of intraamniotic inflammation, but the membranes were characterized by the presence of unusual darkly staining deposits of material immediately beneath the amniotic epithelium. Subsequent special stains revealed these to be colonies of gram-positive cocci. We have been unable to find a previous description of this observation in association with streptococcal or with other types of chorioamnionitis.
在一例B族β溶血性链球菌绒毛膜羊膜炎病例中，观察到一种不寻常的病理表现，即大量细菌菌落紧邻羊膜上皮层下方聚集。产后发生了子宫内膜炎以及新生儿败血症和脑膜炎。脐带和胎盘的组织学检查显示出羊膜腔内炎症的常规特征，但胎膜的特点是在羊膜上皮下方存在异常的深色物质沉积。随后的特殊染色显示这些是革兰氏阳性球菌菌落。我们未能找到此前关于这种与链球菌或其他类型绒毛膜羊膜炎相关的观察结果的描述。
