When cells of Rickettsia rickettsii were suspended at different temperatures in growth medium free of host cells, ultrastructural changes were observed in some of these organisms. Depending upon the temperature and length of incubation, loosely organized cells developed into compact, intensely stained, rod-shaped organisms. These compact cells closely resembled the morphology of the original culture of Rickettsia used for inoculation. Morphological changes were primarily noted in cells maintained at 21 degrees C. The viability of the cells was also affected by the temperature of incubation.
当立氏立克次氏体的细胞在不含宿主细胞的生长培养基中于不同温度下悬浮时，在其中一些微生物中观察到了超微结构变化。根据温度和孵育时间的长短，结构松散的细胞发育成紧凑、染色深的杆状微生物。这些紧凑的细胞与用于接种的立克次氏体原始培养物的形态非常相似。形态学变化主要在维持于21摄氏度的细胞中观察到。细胞的活力也受到孵育温度的影响。
