Two commercially available reagents, latex particles (Bactigen) and Staphylococcus aureus suspensions (Phadebact), were compared for the detection of the capsular polyribitol phosphate antigen of Haemophilus influenzae type b in 18 pediatric patients with proven infections due to H. influenzae type b. Whereas both tests nearly equally detected the antigen in the first urine specimens from the patients, the latex test remained positive significantly longer than did the Phadebact test for serial urine specimens. We conclude that the Bactigen test is slightly more sensitive than the Phadebact test for detecting urinary H. influenzae type b antigen.
比较了两种市售试剂——乳胶颗粒(Bactigen)和金黄色葡萄球菌悬液(Phadebact),用于检测18例经证实由b型流感嗜血杆菌感染的儿科患者尿液中b型流感嗜血杆菌的荚膜多聚核糖醇磷酸抗原。虽然两种检测方法在检测患者的首次尿液标本中的抗原时几乎同样有效,但对于系列尿液标本,乳胶检测呈阳性的时间明显比Phadebact检测更长。我们得出结论,在检测尿液中b型流感嗜血杆菌抗原方面,Bactigen检测比Phadebact检测略敏感。
