Qualitative and quantitative bacterial analysis of 200 samples of middle ear effusions collected from patients with current otitis media was performed. When middle ear pathogens (S. pneumoniae, H. influenzae and B. catarrhalis) were found during current acute otitis media or otitis media with effusion infection, the quantity of these bacteria was of the magnitude 10(6)-10(8)/ml and 0-5 x 10(5)/ml effusion material, respectively. Mucopurulent effusion material contained 6 x 10(5)-10(8) bacteria per ml whereas effusion from chronically discharging ears exceeded 10(9) bacteria per ml. Serous effusions did not harbour middle ear pathogens. The appearance of the effusion material was dependent on the number of bacteria involved. Quantification of bacteria in various middle ear effusions offers opportunities to make the diagnosis of various otitis media infections more accurate and readily comparable.
对从患有当前中耳炎的患者收集的200份中耳积液样本进行了定性和定量细菌分析。当在当前急性中耳炎或积液感染性中耳炎期间发现中耳病原体（肺炎链球菌、流感嗜血杆菌和卡他莫拉菌）时，这些细菌的数量在积液材料中分别为10(6)-10(8)/ml和0-5×10(5)/ml。粘液脓性积液材料每毫升含有6×10(5)-10(8)个细菌，而长期流脓耳的积液每毫升超过10(9)个细菌。浆液性积液未发现中耳病原体。积液材料的外观取决于所涉及细菌的数量。对各种中耳积液中的细菌进行定量分析，为更准确、更易于比较地诊断各种中耳炎感染提供了机会。
