The formation of quasi-multicellular bodies of Treponema denticola was analysed using different electron microscopical methods. These bacteria could develop four different conformations: (i) normal helical forms; (ii) twisted spirochetes, forming plaits; (iii) twisted spirochetes,forming club-like structures; (iv) spherical bodies in different size. Treponemes within spherical bodies, plaits, and clubs proved to be enclosed in a common outer sheath in which the normal arrangement of their axial flagella was lost. The development of the quasi-multicellular bodies starting from the monoforme spirochetes was elucidated and this morphogenetic process is illustrated by a schematic drawing. Factors which might be involved in the induction of the structures are discussed and their possible pathogenetic importance is considered.
利用不同的电子显微镜方法分析了具核梭杆菌准多细胞体的形成。这些细菌可呈现四种不同形态：（i）正常螺旋形态；（ii）扭曲螺旋体，形成辫状结构；（iii）扭曲螺旋体，形成棒状结构；（iv）不同大小的球形体。球形体、辫状结构和棒状结构中的密螺旋体被证明包裹在一个共同的外部鞘中，其轴向鞭毛的正常排列消失。阐明了从单形螺旋体开始的准多细胞体的发育过程，并通过示意图说明了这一形态发生过程。讨论了可能参与诱导这些结构的因素，并考虑了它们可能的致病重要性。
