High prevalence of a host‐associated Anaplasma lineage in wild coatis (Nasua nasua) from the Brazilian Atlantic Forest

Medical and Veterinary Entomology, EarlyView.
Anaplasma sp. DNA was detected in 47.9% of free‐ranging coatis (Nasua nasua) sampled in Iguaçu National Park, southern Brazil. Molecular analyses revealed a genetically distinct Anaplasma lineage infecting coatis, differing from Anaplasma strains detected in associated tick populations.

Acquisition and transmission of Hepatozoon canis (Apicomplexa: Hepatozoidae) by the tick Amblyomma ovale (Acari: Ixodidae)

Veterinary Parasitology, 2009
The present study aimed to evaluate under controlled conditions the acquisition of Hepatozoon canis by Amblyomma ovale after feeding on infected dogs, and the subsequent induction of infection in uninfected dogs that ingested the experimentally infected ticks. Two H. canis naturally infected dogs were infested with A.

Life history traits, habitat characteristics, and phylogeny influence tick infestation probability in tropical wild birds

Journal of Avian Biology, Volume 2025, Issue 3, May 2025.
Interactions between wild birds and ticks exert significant selective forces, influencing the host's evolution and fitness. Tick infestation rates vary among bird species due to life history and morphology. Understanding tick infestation probability is crucial for conservation efforts, as birds play an important role in the tick life cycle and can ...
