A maintenance medium for Treponema pallidum was designed to hold its Eh at the optimum for that organism, -10 to -110 mV. After 100% motile (freshly harvested) T. pallidum was inoculated into the medium, the motility of the treponemes decreased to 80% after 2 days, 50% after 3.5 days, and 0% after 9 days during incubation at 34 C. Full virulence was retained for 2 days, but it dropped rapidly thereafter, and the treponemes became avirulent by day 5.
一种用于梅毒螺旋体的维持培养基被设计用于将其氧化还原电位保持在该生物体的最佳水平,即-10至-110毫伏。将100%活动(刚收获)的梅毒螺旋体接种到培养基中后,在34℃培养期间,螺旋体的活动力在2天后降至80%,3.5天后降至50%,9天后降至0%。其完全毒力保持2天,但此后迅速下降,到第5天螺旋体变得无毒力。
