美国每年有四千万以上的成人因患咽炎就医;咽炎还可使每年度减少一亿个工作日。当患者咽部β-溶血性A族链球菌培养为阴性时,常认为咽炎病因是病毒性的而不予抗细菌治疗。本文作者试图证明抗菌治疗可能对之有效的两种非链球菌性病原体——沙眼衣原体和肺炎支原体在咽炎中的作用。作者在新英格兰的四所综合医院里随机选择了主诉咽痛的763例成年病人进行了为期一年的研究。患者平均年龄为30.9±10.5岁。将咽部刮片培养物按常规划痕法接种在羊血琼脂板上并于厌氧条件下培养,通过β-溶血作用和枯草杆菌
Every year more than 40 million adults in the United States seek medical treatment for pharyngitis. Pharyngitis can also reduce the annual bill by 100 million working days. When the patient’s throat beta-hemolytic group A streptococcal culture is negative, the pharyngitis is often considered etiological and not anti-bacterial treatment. The authors sought to demonstrate the role of two non-streptococcal pathogens, Chlamydia trachomatis and Mycoplasma pneumoniae, in pharyngitis, for which antibacterial therapy may be effective. The authors conducted a one-year study of 763 adult patients who were chiefly complained of sore throat at four general hospitals in New England. The average age of patients was 30.9 ± 10.5 years. The pharyngeal smear cultures were inoculated on sheep blood agar plates according to the conventional scratch method and cultured under anaerobic conditions by β-hemolysis and Bacillus subtilis
