Insights from entire mitochondrial genome sequences into the phylogeny of ticks of the genera Haemaphysalis and Archaeocroton with the elevation of the subgenus Alloceraea Schulze, 1919 back to the status of a genus

open access: yesMedical and Veterinary Entomology, Volume 38, Issue 2, Page 189-204, June 2024.
We sequenced the entire mt genomes of three species of tick for the first time: Bothriocroton auruginans, B. hydrosauri and H. (Kaiseriana) novaeguineae, and we sequenced the 18S rRNA gene of B. hydrosauri and H. (Kaiseriana) bancrofti. In our phylogenetic trees, Alloceraea was the sister to Archaeocroton sphenodonti, from New Zealand; to the exclusion

open access: yesRevista Colombiana de Ciencias Pecuarias, 2017
An accurate knowledge on ecological aspects of ticks is essential to design and evaluate the control methods and to make epidemiological inferences about tick-borne diseases.

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

open access: yesTicks 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.

Free-living ticks in a cerrado fragment, state of Mato Grosso do Sul, Brazil

open access: yesBioscience Journal, 2018
The fatal cases of spotted fever reported in some Brazilian municipalities are generally associated with the presence of ticks and capybaras (Hydrochoerus hydrochaeris). The urban forest fragments where this rodent is present are of great concern.

Dichotomous key to larvae of the genus Amblyomma (Parasitiformes: Ixodidae) in Brazil, with morphological description and redescription of the larval stage of 30 Amblyomma species

open access: yesTicks and Tick-Borne Diseases
Ticks of the genus Amblyomma are of great medical and veterinary importance in Brazil, where they regularly parasitize wild and domestic animals and will bite humans that enter rural and forest areas for work and recreation purposes.

Ticks and serosurvey of anti-Rickettsia spp. antibodies in wild boars (Sus scrofa), hunting dogs and hunters of Brazil.

open access: yesPLoS Neglected Tropical Diseases, 2019
BackgroundRickettsia bacteria are responsible for diseases in humans and animals around the world, however few details are available regarding its ecology and circulation among wild animals and human populations at high transmission risk in Brazil.

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]

open access: yesRevista 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).

Temporal and Spatial Analysis of Vector-Tick Borne Spotted Fever in the State of São Paulo

open access: yesZoonotic Diseases
Brazilian spotted fever (BSF) is a tick-borne acute febrile disease that can be lethal to humans, caused by the bacterium Rickettsia rickettsii. In the State of São Paulo, transmission occurs mainly through two tick species: Amblyomma sculptum and ...

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

open access: yesTicks 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.

Morphodifferentiation of Gené’s organ in engorged Amblyomma sculptum Berlese, 1888 female ticks (Acari: Ixodidae)

open access: yesTicks and Tick-borne Diseases, 2018
The Gené's organ (GO) secretes a waxy substance on eggs that reduces water loss and has antimicrobial properties. The current study evaluated morphological and histochemical aspects of GO in Amblyomma sculptum from the period of post-feeding - when ticks detach from the host - to the stage just before oviposition.
