从理论上讲,鼻咽部可以作为中耳炎病原体的栖居场所,因此鼻咽部分泌物的细菌学鉴定对预示中耳炎病原体是合理的。作者对225例化脓性中耳炎患儿的鼻咽分泌物和中耳渗出物做了细菌学检查。培养方法是把培养物直接接种于巧克力琼脂和5%羊血琼脂平板上,观察12到24小时。中耳分泌物培养153人(68%)分离出病原菌。其中有肺炎链球菌、嗜血流感杆菌、嗜血副流感杆菌、化脓性链球菌、金黄色葡萄球菌和奈瑟氏菌。3例中耳有多种细菌感染,两例无菌生长。
In theory, the nasopharynx can serve as a dominator of otitis media pathogens, and the bacteriological identification of nasopharyngeal secretions is reasonable for predicting otitis media pathogens. The authors performed a bacteriological examination of nasopharyngeal secretions and middle ear exudates in 225 children with purulent otitis media. Cultures were seeded directly onto chocolate agar and 5% sheep blood agar plates for 12 to 24 hours. Middle ear secretions were cultured in 153 (68%) isolates of pathogens. Among them are Streptococcus pneumoniae, Haemophilus influenzae, Paracetamoliasis, Streptococcus pyogenes, Staphylococcus aureus and Neisseria. Three cases of middle ear bacteria infection, two cases of aseptic growth.
