目的了解副流感嗜血杆菌的各种生物型在呼吸道各种疾病中的分布情况。方法自临床各呼吸道疾病病人选取分离菌株 ,并经 API NH进行菌种鉴定的 194株副流感嗜血杆菌 ,按其对吲哚、尿素、鸟氨酸的利用情况进行分型。计算各种生物型在各种疾病中的百分率。结果 194株副流感嗜血杆菌中 ,副流感 、 、 、 、 、 、 、型的分离率分别为 39.7%、30 .9%、13.4%、4.6 %、7.2 %、3.6 %、0 .5 %。肺炎患者以副流感 型为主 5 2 % (38/ 73) ,其次为副流感 型 31.5 % (2 3/ 73) ;而上感患者、支气管炎患者、急性气管炎患者、其他疾病均以副流感 I型为主。结论不同的疾病副流感嗜血杆菌的生物型分布各不相同。引起呼吸道感染的主要为副流感嗜血杆菌 、 型。
Objective To understand the distribution of various biotypes of Haemophilus parainfluenza in various respiratory diseases. Methods A total of 194 strains of Haemophilus parainfluenzae strains were selected from clinical patients with respiratory diseases and identified by API NH. According to their use of indole, urea and ornithine, they were classified. Calculate the percentage of various biotypes in various diseases. Results Among the 194 strains of Haemophilus parainfluenzae, the isolation rate of paraffins was 39.7%, 30.9%, 13.4%, 4.6%, 7.2%, 3.6% and 0.5%, respectively. Parainfluenza was the main cause of pneumonia in 52 (38/73) patients, followed by 31.5% (23/73) in parainfluenza patients. In patients with upper respiratory tract infection, bronchitis, acute bronchitis and other diseases, Type I flu-based. Conclusions The distribution of Haemophilus parahaemolyticus varied according to disease types. Respiratory tract infections caused by the main Haemophilus parainfluenza, type.
