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

open access: yesMedical and Veterinary Entomology, Volume 40, Issue 4, Page 1087-1092, December 2026.
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.

Primary embryonic cells of Rhipicephalus microplus and Amblyomma cajennense ticks as a substrate for the development of Borrelia burgdorferi (strain G39/40)

open access: yesBrazilian Journal of Biology
Borrelia burgdorferi, the agent of Lyme borreliosis, is a spirochetes transmitted by ticks to humans and animals. Its cultivation in vitro in tick cells allows studies of its biology and provides methodology for future research in Brazil, and for the ...

Stable Reference Genes for RT‐qPCR in House Dust Mite Dermatophagoides farinae (Acari: Pyroglyphidae) at Different Developmental Stages

open access: yesEcology and Evolution, Volume 16, Issue 11, November 2026.
First systematic evaluation of reference genes across different developmental stages of Dermatophagoides farinae. RPL18 and RPS28 are identified as the two stable reference genes. Cytochrome P450 3A8 gene validates that these stable reference genes provide robust and consistent expression patterns.

In silico analysis for identification of tick phagotopes selected by phage-displayed libraries Análises in sílico na identificação de fagotopos de carrapatos selecionados por bibliotecas de phage display

open access: yesRevista Brasileira de Parasitologia Veterinária, 2009
Phage display techniques have been widely employed to map epitope structures which have served as the basis for developing molecular vaccines. We have applied this technique to map specific epitopes of Rhipicephalus (Boophilus) microplus.

Plasma Pharmacokinetic Profile of Fipronil 1% Pour‐On in Cattle: Photodegradation and the Sustained Systemic Persistence of Fipronil Sulfone

open access: yesJournal of Veterinary Pharmacology and Therapeutics, Volume 49, Issue 5, Page 515-524, September 2026.
ABSTRACT This study characterized the long‐term pharmacokinetic profile of a 1% fipronil pour‐on formulation in Nellore bulls under field conditions. Seventeen animals received a single topical dose (1 mg/kg), and plasma concentrations of fipronil and its metabolites (sulfone and desulfinyl) were monitored for 175 days using LC–MS/MS.

In vitro activity of Artemisia annua L (Asteraceae) extracts against Rhipicephalus (Boophilus) microplus Atividade in vitro de extratos de Artemisia annua L (Asteraceae) sobre Rhipicephalus (Boophilus) microplus

open access: yesRevista Brasileira de Parasitologia Veterinária, 2011
The activity of plant extracts on parasites may indicate groups of substances that are potentially useful for controlling Rhipicephalus (Boophilus) microplus. The aim of the present study was to investigate the in vitro action of Artemisia annua extracts

Cellular immune response of Amblyomma sculptum and Amblyomma americanum to entomopathogenic fungi: Implications for biological tick control

open access: yesMedical and Veterinary Entomology, Volume 40, Issue 3, Page 582-594, September 2026.
Amblyomma sculptum showed a plasmatocyte‐dominant haemocyte profile. Beauveria bassiana increased plasmatocytes and reduced granulocytes, whereas Metarhizium robertsii did not cause significant changes. Amblyomma americanum showed a granulocyte‐dominant haemocyte profile. Beauveria bassiana reduced total haemocytes and granulocytes. B.

Analysis of Babesia bovis infection-induced gene expression changes in larvae from the cattle tick, Rhipicephalus (Boophilus) microplus

open access: yesParasites & Vectors, 2012
Background Cattle babesiosis is a tick-borne disease of cattle that has severe economic impact on cattle producers throughout the world’s tropical and subtropical countries. The most severe form of the disease is caused by the apicomplexan, Babesia bovis,
