Transovarial transmission

Transovarial or transovarian transmission occurs in certain arthropod vectors as they transmit pathogens from parent to offspring. This process, used by a wide variety of parasites, is also known as vertical transmission. For example, Rickettsia rickettsii, carried within ticks, is passed on from parent to offspring tick by transovarial transmission. This is in contrast to parasites such as Rickettsia prowazekii, which are not passed on by transovarian transmission due to killing the vector that carries it. Other examples of parasites that use this mechanism of transmission include the aedes mosquito vector of the yellow fever virus and in phlebotomine sandflies that transmit pappataci fever.
