目前有些作者认为,肺炎支原体是引起成人非细菌性急性感染性肺病的最常见原因之一。根据不同作者的报道,占所有感染性肺炎的20～54%。在肺炎支原体引起的支气管肺炎中,病因诊断甚为重要,因有指导治疗方案的意义。细胞膜的结构使肺炎支原体对红霉素敏感,对青霉素则呈明显耐药性。肺炎支原体的肺部临床和X线表现并无特异性,诊断主要根据实验室资料,特别是补体结合试验。作者根据70例肺炎支原体引起的肺部X线表现, At present, some authors believe that Mycoplasma pneumoniae is one of the most common causes of non-bacterial acute infectious lung disease in adults. According to different authors, accounting for 20 to 54% of all infectious pneumonia. Bronchial pneumonia caused by Mycoplasma pneumoniae, the etiology of the diagnosis is very important because of the significance of guiding the treatment program. The structure of the cell membrane so that Mycoplasma pneumoniae erythromycin sensitive to penicillin was significantly resistant. Mycoplasma pneumoniae clinical and X-ray showed no specificity, the diagnosis mainly based on laboratory data, especially complement fixation test. According to the authors of 70 cases of Mycoplasma pneumonia caused by pulmonary X-ray performance,
