Distribution and movement of infective-stage larvae of Dipetalonema viteae (Filarioidea) in the vector tick, Ornithodoros tartakowskyi (Argasidae). 1976

I Londoño

Histological sections and dissection of infected ticks, Ornithodoros tartakowskyi, showed that in the resting tick the 3rd-stage larvae of Dipetalonema viteae were distributed in clumps throughout the hemocoel. In the biting tick, larvae moved anteriorly and congregated especially in the capitulum; and the forward migration occurred even though no blood was ingested. This suggests that the act of biting and not the ingestion of blood is the critical factor in migration. The larvae may reach the buccal cavity through 4 possible avenues: 1) the junction of the pharynx with the buccal cavity; 2) the esophagus; 3) the salivary ducts; and 4) the roof of the hypostome. Developing forms produce direct injury to muscle fibers, and the migrating larvae further disorganize the muscles, affecting to some extent the normal activities of the ticks.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013987	Ticks	Blood-sucking acarid parasites of the order Ixodida comprising two families: the softbacked ticks (ARGASIDAE) and hardbacked ticks (IXODIDAE). Ticks are larger than their relatives, the MITES. They penetrate the skin of their host by means of highly specialized, hooked mouth parts and feed on its blood. Ticks attack all groups of terrestrial vertebrates. In humans they are responsible for many TICK-BORNE DISEASES, including the transmission of ROCKY MOUNTAIN SPOTTED FEVER; TULAREMIA; BABESIOSIS; AFRICAN SWINE FEVER; and RELAPSING FEVER.
