Rickettsial Infection in Animals and Brazilian Spotted Fever Endemicity
Emerging Infectious Diseases, 2005 We compared the rickettsial infection status of Amblyomma cajennense ticks, humans, dogs, and horses in both Brazilian spotted fever (BSF)–endemic and –nonendemic areas in the state of São Paulo, Brazil.

Structural basis of chemokine recognition by the class A3 tick evasin EVA‐ACA1001
Protein Science, Volume 33, Issue 6, June 2024.Abstract Ticks produce chemokine‐binding proteins, known as evasins, in their saliva to subvert the host's immune response. Evasins bind to chemokines and thereby inhibit the activation of their cognate chemokine receptors, thus suppressing leukocyte recruitment and inflammation.

Allergy, Volume 79, Issue 6, Page 1440-1454, June 2024.Abstract The recent recognition of a syndrome of tick‐acquired mammalian meat allergy has transformed the previously held view that mammalian meat is an uncommon allergen. The syndrome, mediated by IgE antibodies against the oligosaccharide galactose‐alpha‐1,3‐galactose (alpha‐gal), can also involve reactions to visceral organs, dairy, gelatin and ...

Medical 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

Transboundary and Emerging Diseases, Volume 2024, Issue 1, 2024.The application of tick control strategies on tropical dairy cattle strongly relies on farmers’ uptake, knowledge, and perceptions of the efficacy of control measures. This study aims to identify common and uncommon tick control practices employed by dairy farmers in subtropical areas of Ecuador and associate them with the presence of infestation and ...

Detection of Brucella in Dermacentor Ticks of Wild Boar with Brucellosis
Transboundary and Emerging Diseases, Volume 2024, Issue 1, 2024.Brucellosis is a sanitary and economically relevant disease affecting humans, livestock, and wildlife. Ticks have been suggested as vectors, long‐term carriers, and amplifiers of Brucella. In this study, ticks from wildlife ungulate hosts living in hunting reserves of a central region of Spain were collected during a 6‐year period, pooled, and screened
