在一项关于立克次体经卵传递给实验和自然感染的安氏革蜱后代的定量研究中，发现所有受感染的雌性蜱都通过卵将立克次体传递给几乎100%的后代。感染在整个子代中保留，并再次由所有F1雌性试验传播给100%的子代。荧光抗体染色切片检查卵巢组织感染的雌性蜱揭示存在立克次体在每个卵子;有机体经常被发现在细胞质中，但从来没有在细胞核的发展鸡蛋。在研究过程中，R.通过将蜱卵接种到鸡胚中和将蜱喂给豚鼠，立克次体保持不变。
In a quantitative study of transovarial passage of Rickettsia rickettsii to the progeny of experimentally and naturally infected wood ticks, Dermacentor andersoni, it was found that all infected female ticks tested passed rickettsiae via eggs to almost 100% of their offspring. Infection was retained throughout the filial generation and was again transmitted by all F1 females tested to 100% of their progeny. Examination of fluorescent-antibody stained sections of ovarian tissues of infected female ticks revealed the presence of rickettsiae in every ovum; organisms were regularly found in the cytoplasm but never in the nuclei of developing eggs. During the study, inactivity of the strains of R. rickettsii re-mained unchanged, as indicated by inoculation of tick eggs into chick embryos and by feeding of ticks on guinea pigs.
