In vitro cultivation of the virulent Nichols strain of Treponema pallidum was achieved in a tissue culture system as described by A. H. Fieldsteel, D. L. Cox, and R. A. Moeckli (Infect. Immun. 32:908-915, 1981). In 7 of 8 experiments, 8.9- to 26.2-fold increases in the number of T. pallidum were observed over a 12- to 12-day period of incubation.
按照A. H. 菲尔德斯蒂尔、D. L. 考克斯和R. A. 莫埃克利所述的组织培养系统(《感染与免疫》32:908 - 915, 1981年),实现了梅毒螺旋体强毒株尼科尔斯株的体外培养。在8次实验中的7次,在12至12天的孵育期内,观察到梅毒螺旋体数量增加了8.9至26.2倍。
