Ticks (Acari: Ixodidae) and tick-borne agents associated with domestic dogs in an environmental protection area in Brazil, with molecular evidence of Rhipicephalus linnaei (Audouin, 1826) [PDF]

Revista Brasileira de Parasitologia Veterinária
Wild animals and domestic dogs living in human dwellings near forested areas can share ectoparasites, including ticks. In this study, we surveyed ticks associated with dogs which tutors living in the Palmares Environmental Protection Area (EPA Palmares).

Comparative survival of the engorged stages of Amblyomma cajennense sensu stricto and Amblyomma sculptum under different laboratory conditions

Ticks and Tick-borne Diseases, 2018
Recent studies indicated that the taxon Amblyomma cajennense (Fabricius, 1787) is a complex of 6 valid species, of which only two, Amblyomma cajennense sensu stricto (s.s.) and Amblyomma sculptum Berlese, 1888 are present in Brazil; the former species is found exclusively in areas of the Amazon biome, and A.

Minimum infection rate of Ehrlichia minasensis in Rhipicephalus microplus and Amblyomma sculptum ticks in Brazil

Ticks and Tick-borne Diseases, 2016
A new genotype phylogenetically close to Ehrlichia canis named as Ehrlichia minasensis was identified infecting cattle and deer in Canada, as well as Rhipicephalus microplus ticks and cattle in Brazil. Although it was detected in R. microplus, little is known about the epidemiology of this ehrlichiosis, especially in other tick species.

Phenology of Amblyomma sculptum in a degraded area of Atlantic rainforest in north-eastern Brazil

Ticks and Tick-borne Diseases, 2019
Amblyomma sculptum is the principal vector of Rickettsia rickettsii, the main agent of spotted fever rickettsiosis in Brazil. Little information is available regarding the population dynamics of this tick in some regions, including north-eastern Brazil, where cases of spotted fever rickettsioses are increasingly reported.
