An ultrastructural comparative analysis is reported on the replication cycle of six strains of Chlamydia trachomatis, recently isolated, and Chlamydia psittaci strain 6BC, grown in cell cultures. Important morphological distinctions of the bacterial walls are documented. In Chlamydia trachomatis the cell wall seems more rigid. This causes, during the morphogenesis of the elementary body, its separation from the cell membrane with formation of an electron transparent space, which is not demonstrable in Chlamydia psittaci. As a result of this process, the appearance of "ghosts" and "mini reticular bodies" is documented. Budding and multiple fission are suggested as possible mechanisms of replication of Chlamydia trachomatis, in coexistence or/as alternative to binary fission.
本文报道了对最近分离出的六种沙眼衣原体菌株以及鹦鹉热衣原体6BC菌株在细胞培养物中的复制周期进行的超微结构比较分析。记录了细菌细胞壁的重要形态学差异。在沙眼衣原体中,细胞壁似乎更坚硬。这导致在原体的形态发生过程中,原体与细胞膜分离并形成电子透明空间,而在鹦鹉热衣原体中则未观察到这种现象。由于这一过程,记录到了“空壳”和“微型网状体”的出现。出芽和多分裂被认为是沙眼衣原体可能的复制机制,它们与二分裂共存或作为二分裂的替代方式。
