中耳炎是儿童最常见的感染之一,一般根据常见病原体在体外对药物的敏感度、临床效果、副作用以及用药费用来选择治疗急性中耳感染的药物。从中耳抽出液的培养物鉴定与中耳炎有关的细菌,有肺炎链球菌、流感嗜血杆菌和A组β溶血链球菌,金黄色葡萄球菌、厌气性杆菌和衣原体也常分离得到。约从20%的患急性中耳炎的满6周的婴儿的中耳抽出液中曾分离出革兰氏阴性肠杆菌。 Otitis media is one of the most common infections in children and is generally based on the sensitivity, clinical efficacy, side effects, and cost of administration of common pathogens in vitro to the treatment of acute middle ear infections. Extracts from the middle ear cultures were also identified for otitis media-related bacteria, S. pneumoniae, H. influenzae and Group A. hemolyticus, Staphylococcus aureus, anaerobic bacilli, and Chlamydia. Gram-negative enterobacteria have been isolated from the middle ear extract from about 20% of infants with acute otitis media for 6 weeks.
