Abstract

The latex agglutination method, utilizing antibody-coated latex particles, was adapted for serogrouping of Neisseria meningitidis and serotyping of encapsulated Haemophilus influenzae strains from agar plates. It was found to give more clear-cut results than conventional slide agglutination. A 100% agreement with the antiserum agar method was found for all strains isolated from blood or cerebrospinal fluid. Many meningococcal strains from nasopharyngeal carriers are autoagglutinable, but some of these gave a positive reaction with the group B latex reagent, although they were negative by the antiserum agar method. The latex agglutination method has several advantages over others: the lack of autoagglutination, easy performance, easy interpretation, and very low consumption of antisera.

摘要

利用包被抗体的乳胶颗粒的乳胶凝集法,被用于从琼脂平板上对脑膜炎奈瑟菌进行血清群分型以及对有荚膜的流感嗜血杆菌菌株进行血清分型。结果发现,该方法比传统玻片凝集法能给出更明确的结果。从血液或脑脊液中分离出的所有菌株,该方法与抗血清琼脂法的结果完全一致。许多来自鼻咽部携带者的脑膜炎球菌菌株可自身凝集,但其中一些与B群乳胶试剂呈阳性反应,尽管用抗血清琼脂法检测为阴性。乳胶凝集法相对于其他方法有几个优点:无自身凝集现象、操作简便、结果易判读且抗血清消耗极低。
