支原体最早是由 Nocard等人从患有胸膜肺炎的牛胸腔积液中分离出来的[1 ] 。因当时未能鉴定其种属 ,暂称之为牛胸膜肺炎微生物。以后科学家们相继从其他动物疾病中也分离出相似的病原体 ,统称为类胸膜肺炎微生物。与 60年代早期证实该微生物可引起非典型性肺炎[2 ] ,因此类微生 Mycoplasma was first isolated by Nocard et al. From bovine pleural effusion with pleuropneumonia [1]. Because at that time failed to identify their species, tentatively called bovine pleuropneumoniae microorganisms. Later, scientists have also isolated similar pathogens from other animal diseases, collectively referred to as pleuropneumoniae microorganisms. And the early 1960s confirmed that the microorganism can cause atypical pneumonia [2], so micro-organisms
