To investigate the presence Mycoplasma pneumoniae and Chlamydia pneumoniae and to determine their importance as the cause of community-acquired pneumonia in childhood.
We performed a retrospective descriptive study of all the patients aged less than 15 years old diagnosed with community-acquired pneumonia due to M. pneumoniae in the pediatric emergency department of our hospital between May 1998 and May 2000. Patients in whom C. pneumoniae was also identified as a cause of pneumonia were investigated.
Of 242 cases of community-acquired pneumonia, 82 were due to M. pneumoniae (34.7 %) and 32 were due to C. pneumoniae (13.22 %) Of these, eight cases were coinfections with C. pneumoniae and M. pneumoniae. Most infections occurred in boys (5/8). The mean age at diagnosis was 7.7 years. No seasonal predominance was found.
Both C. pneumoniae and M. pneumoniae play a substantial role in community-acquired pneumonia in children aged more than 5 years old. Although coinfection with both species usually worsens the course of the disease, outcome in all the patients studied was satisfactory.
调查肺炎支原体和肺炎衣原体的存在情况，并确定它们作为儿童社区获得性肺炎病因的重要性。
我们对1998年5月至2000年5月间在我院儿科急诊科诊断为肺炎支原体所致社区获得性肺炎的所有15岁以下患者进行了回顾性描述性研究。对同时被确定为肺炎病因的肺炎衣原体患者进行了调查。
在242例社区获得性肺炎病例中，82例由肺炎支原体引起（34.7%），32例由肺炎衣原体引起（13.22%）。其中，8例为肺炎衣原体和肺炎支原体混合感染。大多数感染发生在男孩中（5/8）。诊断时的平均年龄为7.7岁。未发现季节性优势。
肺炎衣原体和肺炎支原体在5岁以上儿童社区获得性肺炎中均起重要作用。虽然两种病原体混合感染通常会使疾病病程恶化，但所有研究患者的结局均令人满意。
