肺炎衣原体常常是引起呼吸道感染的原因,另外,有许多报告显示,肺炎衣原体感染与局部缺血性心脏病有关,当在组织内(包括尾鞭型动脉粥样硬化组织)检测到肺炎衣原体抗原和DNA的时候,可能发生了持续感染。最近用敏感的PCR技术不仅能够在心血管病人外周血单核细胞(PBMNCs)内检测到肺炎衣原体DNA,而且也能够在中年献血者的PBMNCs内检测到。在瑞典北部携带肺炎衣原体DNA的献血者百分率(46％)很高。最近对冠状动脉心脏病病人的研究,使从循环的单核细胞中培养肺 Chlamydia pneumoniae is often the cause of respiratory tract infections. In addition, many reports show that Chlamydia pneumoniae infection is associated with ischemic heart disease. Chlamydia pneumoniae antigens are detected in tissues (including tilapia-type atherosclerosis) and DNA, there may be a persistent infection. Recent use of sensitive PCR technology not only detects C. pneumoniae DNA in cardiovascular patients’ peripheral blood mononuclear cells (PBMNCs), but it can also be detected in PBMNCs of middle-aged donors. The percentage of donors carrying C. pneumoniae DNA in northern Sweden (46%) is high. Recent studies in patients with coronary heart disease have led to the development of lungs from circulating monocytes
