从1967年首次发现类菌原体(Mycopl asma Like Orgnisms,简称MLO)是一些植物黄化型疾病的病原以来,世界上许多实验室中的研究者们都期望能够找到这种病原微生物的体外培养方法。然而,迄今只有少数几种产生螺旋状和能动丝状物的类菌原体在体外培养成功,并将其归为一个新病 Since the first discovery of the Mycoplasma Asma Like Orgnisms (MLOs) in 1967 as the causal agent of some plant yellowing diseases, researchers in many laboratories around the world are hoping to find out the in vitro culture of this pathogenic microorganism method. However, to date, only a few species of spawns producing helical and dynamic filaments have been successfully cultured in vitro and classified as a new disease
