The aerobic and anaerobic bacterial flora of middle ear exudate (MEE) of 47 consecutive patients with chronic suppurative otitis media were studied using a quantitative bacteriological technique under strictly anaerobic conditions. Specimens from the external auditory canal (EAC) and the nasopharynx (NP) were obtained in order to correlate the bacterial findings with those of the MEE. Aerobic bacteria were invariably present in the MEE, the predominant aerobic species being Pseudomonas, found in 32%. Anaerobic bacteria were found in 45%: most anaerobes (55%) were cocci, 33% were of the Bacteroides species. The flora of the MEE correlated well with the bacteriological findings in the EAC cultures. In contrast, most organisms isolated from the NP represented the normal skin flora or were common respiratory pathogens.
采用定量细菌学技术，在严格厌氧条件下，对47例慢性化脓性中耳炎患者的中耳渗出液（MEE）中的需氧和厌氧菌群进行了研究。采集外耳道（EAC）和鼻咽部（NP）的标本，以便将细菌学检查结果与MEE的结果进行对比。MEE中始终存在需氧菌，主要的需氧菌是铜绿假单胞菌，占32%。45%的患者MEE中发现了厌氧菌：大多数厌氧菌（55%）为球菌，33%为拟杆菌属。MEE中的菌群与EAC培养物中的细菌学检查结果密切相关。相比之下，从NP分离出的大多数微生物代表正常皮肤菌群或常见呼吸道病原体。
