Tick bites, IgE to galactose‐alpha‐1,3‐galactose and urticarial or anaphylactic reactions to mammalian meat: The alpha‐gal syndrome

open access: yesAllergy, 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 ...

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

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.
