本研究结果证明鸡败支原体56具有植物致病性。该支原体的营养形态和可活但不可培养（VBNC）形态可以通过根系组合感染植物，侵入不同组织，在那里持续存在并引起植物原体特有的破坏事件。与营养形态相比，VBNC形态的破坏性变化更为显著。这种现象可能与细菌细胞中负责毒力的蛋白质表达增加有关。鉴于鸡芽孢杆菌S6对植物具有毒力特征（传染性、侵袭性、持久性和毒性），考虑到该细菌可能存在无症状携带者，似乎需要开发新的方法来控制植物原体。(c) 2009 Elsevier GmbH版权所有。
The data obtained in this study proved that Mycoplasma gallisepticum 56 known as avian pathogen had a phytopathogenic potential. The vegetative forms and the viable but nonculturable (VBNC) forms of this mycoplasma could infect the plants via an assemblage of rootlets, invade different tissues, persist there and cause destructive events characteristic to phytomycoplasmoses. In comparison with the vegetative forms, the VBNC forms induced more prominent destructive changes. This phenomenon might be connected to increasing expression of proteins responsible for virulence in the bacterial cells. The fact that M. gallisepticum S6 could demonstrate virulent features (infectivity, invasiveness, persistence and toxigenicity) in regard to plants seems to require a development of new ways for controlling phytomycoplasmoses taking into account the probable presence of asymptomatic carriers of this bacterium.
