1898年,巴斯德研究所的Nocard等发现一种比普通细菌更简单、能独立生存的微生物,它可引起动物和人类疾病,被称为支原体。经几十年研究,在支原体的形态结构、分离培养、与人类疾病的关系方面,取得了相当的进展。但是,这种认识还不完善,新的支原体种类不断地被发现,除少数支原体如肺炎支原体(M. Pneumoniae)的流行病学与临床研究比较深入外,它们的致病研究还缺少更多的证据。1967年发现支原体spiroplasma可使植物致病,因此推测有许多原来认为是病毒引起的植物疾病是由支
In 1898, Nocard et al., The Pasteur Institute, discovered a simpler, viable microorganism than ordinary bacteria that can cause animal and human diseases called Mycoplasma. After decades of research, considerable progress has been made in the relationship between the morphological structure of Mycoplasma, isolation and culture, and human diseases. However, this understanding is not perfect. The new species of Mycoplasma is constantly being discovered. Except for the epidemiological and clinical studies of a few Mycoplasmas such as M. pneumoniae, their pathogenicity studies lack more evidence. 1967 Mycoplasma spiroplasma was found to cause disease in plants, it is speculated that there are many originally thought to be caused by the virus plant disease by the branch
