Evaluation of the transmission of Anaplasma marginale by Amblyomma tonelliae.

This study aimed to evaluate A. marginale transstadial (TST) and transovarial transmission (TOT) by Amblyomma tonelliae through vector competence assays and analysis of natural infection in free-living ticks. This three-host tick species was chosen as model because it is a usual parasite of cattle in all their parasitic stages, making them potential vectors through TST or TOT.

Do parapatric populations of the ticks Amblyomma tonelliae Nava, Beati & Labruna, 2014 and Amblyomma sculptum Berlese, 1888 (Acari: Ixodidae) hybridize?

This work aimed to determine if the tick species, Amblyomma sculptum and Amblyomma tonelliae, hybridize along their contact zones in Argentina. Free-living adults and nymphs of A. sculptum and A.

Fascioliasis in Llama, , in Andean Endemic Areas: Experimental Transmission Capacity by the High Altitude Snail Vector and Epidemiological Analysis of Its Reservoir Role.

South American camelids are definitive hosts of . However, their capacity to participate in the transmission and epidemiology of fascioliasis has never been appropriately studied. Therefore, an isolate from Argentine llama is for the first time analyzed using lymnaeids from Bolivia.
