High-resolution prediction models for Rhipicephalus microplus and Amblyomma cajennense s.l. ticks affecting cattle and their spatial distribution in continental Ecuador using bioclimatic factors. [PDF]
Exp Appl AcarolIn Ecuador, the main tick species affecting cattle are Rhipicephalus microplus and Amblyomma cajennense sensu lato. Understanding their spatial distribution is crucial. To assess their distribution, data from 2895 farms visited between 2012 and 2017 were

Amblyomma cajennense Sensu Stricto (Fabricius, 1787) and Amblyomma sculptum (Berlese, 1888) Tick Saliva Elicit Immune-Modulatory Activity in Isolated Murine Macrophages With an Insight Into Proteomic Analysis. [PDF]
Parasite ImmunolTick saliva is known to cause immunosuppression and help pathogen transmission. Amblyomma sculptum is a public health concern as a vector of Rickettsia rickettsii. Another close‐related species is Amblyomma cajennense sensu stricto (s.s.).

Amblyomma cajennense is an intrastadial biological vector of Theileria equi. [PDF]
Parasit Vectors, 2013 The apicomplexan hemoprotozoan parasite Theileria equi is one of the etiologic agents causing equine piroplasmosis, a disease of equines that is endemic throughout large parts of the world. Before 2009 the United States had been considered to be free of this parasite.

Equine piroplasmosis associated with Amblyomma cajennense Ticks, Texas, USA. [PDF]
Emerg Infect Dis, 2011 We report an outbreak of equine piroplasmosis in southern Texas, USA, in 2009. Infection prevalence reached 100% in some areas (292 infected horses). Amblyomma cajennense was the predominant tick and experimentally transmitted Theileria equi to an uninfected horse. We suggest that transmission by this tick species played a role in this outbreak.
