新近认为肺炎衣原体 TWAR 株能引起肺炎和支气管炎等急性呼吸道感染。有关治疗这些感染的资料很有限。体外敏感性试验提示四环素和红霉素是最有效的制剂,但临床报道四环素的疗效有些不一,有部分病例需重复治疗。同样红霉素虽通常有效,但当剂量小或疗程短时,常难于迅速奏效。氟嗪酸(ofloxacin)是氟喹诺酮类药物的一种新制剂,体外实验和临床上已证明对治疗沙眼衣原体和鹦鹉热衣原体感染很有效。作者据此研究该药在治疗肺炎衣原体感染的作用。病人和方法研究对象为87例门诊或住院的有下 Recently, Chlamydia pneumoniae strain TWAR can cause acute respiratory infections such as pneumonia and bronchitis. There is limited information on the treatment of these infections. In vitro sensitivity tests suggest that tetracycline and erythromycin is the most effective preparation, but the clinical efficacy of tetracycline reported somewhat different, in some cases need to be repeated treatment. The same erythromycin is usually effective, but when the dose is small or short duration, often difficult to work quickly. Ofloxacin is a new formulation of fluoroquinolones that has been shown to be clinically and clinically effective in treating Chlamydia trachomatis and Chlamydia psittaci infections. The authors study the drug in the treatment of Chlamydia pneumoniae infection. Patients and Methods The study population was 87 outpatients or hospitalized patients
