A biotype analysis was performed on serologically nontypable Haemophilus influenzae isolates from the middle ear effusions and nasopharynges of 33 children with chronic otitis media with effusion (serous otitis media). Over 50% of the H. influenzae isolates from the middle ears belonged to biotype II. The incidence of beta-lactamase production was 17%. The results of this study indicate that future clinical or experimental investigations of chronic otitis media with effusion induced by serologically nontypable H. influenzae should focus on this clinically important biotype.
对33例患有慢性渗出性中耳炎(浆液性中耳炎)儿童的中耳积液和鼻咽部中血清学不可分型的流感嗜血杆菌分离株进行了生物型分析。中耳分离出的流感嗜血杆菌中超过50%属于生物型II。β-内酰胺酶产生率为17%。本研究结果表明,未来对血清学不可分型流感嗜血杆菌引起的慢性渗出性中耳炎进行临床或实验研究时,应关注这一具有临床重要性的生物型。
