Transovarial transmission (TOT) is an efficient vertical transmission of pathogens that is observed in many arthropod vectors. This method seems to be an evolutionarily unique development observed only in Babesia sensu stricto (clade VI) and Rickettsia spp., whereas transstadial transmission is the common/default way of transmission. Transovarial transmission does not necessarily contribute to the amplification of tick-borne pathogens but does contribute to the maintenance of disease in the environment. This review aims to provide an updated summary of previous reports on TOT of tick-borne pathogens.
经卵传播(TOT)是一种在许多节肢动物媒介中观察到的高效垂直传播病原体的方式。这种方法似乎是仅在狭义巴贝斯虫(VI 群)和立克次氏体属中观察到的进化独特的发展,而经胚胎期传播是常见/默认的传播方式。经卵传播不一定有助于蜱传病原体的扩增,但有助于疾病在环境中的维持。本综述旨在提供蜱传病原体经卵传播的以往报告的最新总结。
