The pharyngeal aspirates collected from 400 babies at the time of delivery were examined for the presence of bacteria, especially group B streptococci. Aspirates from 79 babies were found to contain viable bacteria, including 4 with group B streptococci; one of these 4 babies developed streptococcal meningitis within 24 hours. The group B streptococci were seen on a Gram-stained film of the aspirate, and were detectable by coagglutination and countercurrent immunoelectrophoresis within 4 hours and by culture after 24 hours. Examination of pharyngeal aspirates may be of value as a screening test for neonatal sepsis.
在分娩时从400名婴儿采集咽吸出物,检测其中细菌的存在情况,尤其是B族链球菌。发现79名婴儿的吸出物含有活菌,其中4名含有B族链球菌;这4名婴儿中有1名在24小时内发生了链球菌性脑膜炎。在吸出物的革兰氏染色涂片上可见B族链球菌,4小时内通过协同凝集和对流免疫电泳可检测到,24小时后通过培养可检测到。咽吸出物检查作为新生儿败血症的筛查试验可能有价值。
