Comparative Susceptibility of Larval Stages of Amblyomma aureolatum, Amblyomma cajennense, and Rhipicephalus sanguineus to Infection by Rickettsia rickettsii [PDF]
Journal of Medical Entomology, 2008 The current study compared the susceptibility of larval stages of Amblyomma cajennense (F.), Amblyomma aureolatum (Pallas), and Rhipicephalus sanguineus (Latreille) to infection by a Brazilian strain of Rickettsia rickettsii. Guinea pigs experimentally infected by R. rickettsii were simultaneously infested by larvae of the three tick species. Recovered

Virome analyses of Amblyomma cajennense and Rhipicephalus microplus ticks collected in Colombia. [PDF]
Acta TropTick-borne viruses (TBV) have gained public health relevance in recent years due to the recognition of human-associated fatal cases and the increase in tick-borne disease and transmission. However, many tick species have not been studied for their potential to transmit pathogenic viruses, especially those found in Latin America.

Lack of parthenogenesis by Amblyomma cajennense (Acari: Ixodidae) [PDF]
Memórias do Instituto Oswaldo Cruz, 2002 Some reproductive parameters of adult stages of Amblyomma cajennense ticks were studied. The capacity of virgin females to reproduce by parthenogenesis was evaluated, during an experimental infestation, in absence of males, on a horse (Equus cabalus). Ticks were spread either completely free or in limited sites on the body of the animal.

Pest Management Science, Volume 79, Issue 11, Page 4328-4334, November 2023., 2023 The baseline susceptibility of Haemaphysalis longicornis to organophosphate, carbamate and pyrethroid acaricides was calculated using a larval package approach. Results indicate that the Asian longhorned tick is susceptible to pyrethroids, coumaphos and carbamates, and should also be effective for controlling H. longicornis.

A risk assessment of equine piroplasmosis entry, exposure and consequences in the UK
Equine Veterinary Journal, Volume 55, Issue 2, Page 282-294, March 2023., 2023 Abstract Background Equine piroplasmosis (EP) is currently not endemic in the UK, despite a lack of formal surveillance and the presence of carrier horses in the equine population. Pathogen establishment would have significant welfare and economic impacts on the national equine industry, but the disease is often overlooked by UK practitioners ...
