为了解老年呼吸道肺炎支原体感染现状及特点。在门诊或（和）住院呼吸道感染病人中，应用聚合酶链反应法检测患者咽试、痰或／和血标本，并密切观察临床症状、体征变化。结果示肺炎支原体感染中，儿童及少年组（＜１７岁）患者２８例，占６９９％；成人组（１８～５９岁）患者６１例，占１９６％；老年组（≥６０岁）患者３３例，占１０６％。老年组病例以男性为主，平均发病年龄６７３±５２岁，多发生于冬季，表现以咳嗽、咳痰、气促、胸片异常，临床诊断为慢性支气管炎继发感染为主（占４８％），经抗炎治疗后症状较儿童组消退慢。建议在慢性阻塞性肺病中常规查肺炎支原体，选用氨基甙或大环内酯类药物治疗肺炎支原体感染
In order to understand the status and characteristics of elderly respiratory Mycoplasma pneumoniae infection. In outpatients or (and) hospitalized patients with respiratory tract infections, the application of polymerase chain reaction test pharyngeal examination, sputum or / and blood samples, and close observation of clinical symptoms and signs.
