WILD ANIMALS TICKS IN THE CERRADO BIOME SCREENED BY THE CETAS, IBAMA-GOIÁS

Ciência Animal Brasileira, 2016
Cerrado biome has around 320,000 species of animals and it occupies approximately 25% of the Brazilian territory. This great number of species stimulates the illegal trafficking of wild animals.

Epidemiology of capybara-associated Brazilian spotted fever.

PLoS Neglected Tropical Diseases, 2019
BACKGROUND:Brazilian spotted fever (BSF), caused by the bacterium Rickettsia rickettsii, has been associated with the transmission by the tick Amblyomma sculptum, and one of its main hosts, the capybara (Hydrochoerus hydrochaeris).

Phylogenetic Inferences Based on Distinct Molecular Markers Confirm a Novel Babesia Species (Babesia goianiaensis nov. sp.) in Capybaras (Hydrochoerus hydrochaeris) and Associated Ticks

Microorganisms, 2023
Piroplasmids (order Piroplasmida) are a diverse group of tick-borne protozoa that may cause disease in animals and occasionally in humans. Novel Piroplasmida clades and species have been found in wild animals from Brazil based on the phylogenetic ...

Emerg Infect Dis [PDF]

We report molecular detection of Rickettsia africae in Amblyomma ovale ticks from Nicaragua and a novel rickettsial strain in an A. triste tick. Of 146 ticks from dogs, 16.4% were Rickettsia PCR positive. The presence of Rickettsia spp.

Harnessing 50 years of tick population genetics: Choosing the right molecular tool for contemporary research

Journal of Animal Ecology, Volume 94, Issue 11, Page 2159-2177, November 2025.
Population genetics reveals how ticks interact with hosts, microbiomes and environments. This review guides researchers in choosing the best tool for the job, weighing cost, resolution, reproducibility and throughput to study tick population structure. Abstract Ticks are ectoparasites of major medical, veterinary and ecological importance, transmitting

Host–parasite relationship in urban environments: A network analysis of haemoparasite infections in Nasua nasua Linnaeus (South American coati)

Medical and Veterinary Entomology, Volume 39, Issue 3, Page 456-463, September 2025.
Urban environments alter host–parasite dynamics, as seen in Nasua nasua, where haemotropic Mycoplasma plays a key role in parasite spread through frequent social interactions. Network analysis revealed low modularity in interactions between N. nasua and tick‐borne haemoparasites, with functional roles unaffected by biotic factors, tick infestation or ...

Detection of Amblyomma mixtum (Acari: Ixodidae) in Germany on a Human Traveler Returning from Cuba [PDF]

, 2020
The importation of exotic ticks to Germany on infested humans is rarely reported. Here we describe the detection of an Amblyomma mixtum nymph harboring Rickettsia amblyommatis by a tourist returning from a holiday trip to Cuba.

Comparative survival of the engorged stages of Amblyomma dubitatum and Amblyomma sculptum in the laboratory: Implications for Brazilian spotted fever epidemiology

Ticks and Tick-borne Diseases, 2020
Brazilian spotted fever (BSF), caused by the bacterium Rickettsia rickettsii, is transmitted to humans mainly by the tick Amblyomma sculptum in southeastern Brazil. In most BSF-endemic areas A. sculptum populations are sustained chiefly by capybaras (Hydrochoerus hydrochaeris), which are also the host of another tick species, Amblyomma dubitatum, not ...
