摘要 通过鼓膜针吸法收集 75 名原发性急性中耳炎儿童的中耳分泌物，并检查其是否存在细菌、细菌 L 型和支原体。在 60 例 (80%) 病例中，通过培养发现了细菌。分离出肺炎双球菌占 50.7%，流感嗜血杆菌占 14.7%，A 族链球菌占 5.3%，卡他奈瑟菌占 9.3%。仅在为分离 L 型而设计的培养基上才从 2 例病例中分离出肺炎支原体。在 15 例培养结果呈阴性的病例中，有 5 例通过对渗出液进行显微镜检查获得了细菌感染的证据。任何渗出液中均未发现支原体。喉咙的细菌发现对于评估中耳炎的病因没有什么价值。另一方面，除了一个病例外，从中耳分泌物中分离出的细菌都是从鼻咽中分离出来的。从中耳分泌物中分离出的细菌被重新...
AbstractFrom 75 children with primary acute otitis media middle ear exudate was collected by needle aspiration through the tympanic membrane and investigated with respect to the presence of bacteria, bacterial L forms and mycoplasmas. In 60 cases (80%) bacteria were found by cultivation. Diplococcus pneumoniae was isolated in 50.7%, Haemophilus influenzae in 14.7%, group A streptococci in 5.3% and Neisseria catarrhalis in 9.3%. From 2 cases D. pneumoniae was isolated only on media designed for the isolation of L forms. In 5 of the 15 cases with negative culture findings, evidence for a bacterial infection was obtained by microscopic examination of the exudate. Mycoplasma was not demonstrated in any of the exudates. The bacterial findings from the throat were of little value in assessing the aetiology of otitis media. On the other hand, the bacterium isolated from the middle ear exudate was isolated from the nasopharynx in all but one case. The bacterium that was isolated from the middle ear exudate was re...
