肺炎支原体(MP)是引起社区获得性肺炎(CAP)的重要病原体之一,可引起肺炎支原体肺炎(MPP),儿童及成人均易感这一特殊病原体,并且近年来MPP发病人数呈增高之势。MP不仅可以引起呼吸道感染,并可在呼吸道感染基础上并发心血管系统、皮肤黏膜、消化系统、血液系统、骨骼肌肉系统、神经系统、泌尿系统等肺外多系统器官的疾病。迄今,MPP的发病机制仍未完全明确,目前国内外学者的研究主要倾向于MP的黏附、侵入、直接造成细胞损伤及免疫学说。探讨其发病机制有利于指导临床治疗、评价治疗效果及预后。
Mycoplasma pneumoniae (MP) is one of the most important causative agents of community-acquired pneumonia (CAP). It can cause mycoplasma pneumoniae (MPP), a special pathogen that is susceptible to both children and adults. In recent years, the incidence of MPP has been on the rise . MP not only can cause respiratory tract infection, but also can be based on respiratory tract infection complicated by cardiovascular system, mucocutaneous mucosa, digestive system, hematological system, skeletal muscle system, nervous system, urinary system and other extrapulmonary diseases. So far, the pathogenesis of MPP is still not completely clear. At present, the researches of domestic and foreign scholars tend to adhere to and invade MPs directly and cause cell injury and immunology. To explore its pathogenesis is conducive to guiding clinical treatment, evaluation of treatment and prognosis.
