Transmission dynamics and control of Rickettsia rickettsii in populations of Hydrochoerus hydrochaeris and Amblyomma sculptum. [PDF]
Brazilian Spotted Fever (BSF), caused by the bacterium Rickettsia rickettsii, is the tick-borne disease that generates the largest number of human deaths in the world. In Brazil, the current increase of BSF human cases has been associated with the presence and expansion of capybaras Hydrochoerus hydrochaeris, which act as primary hosts for the tick ...

EAACI Molecular Allergology User's Guide 2.0
Abstract Since the discovery of immunoglobulin E (IgE) as a mediator of allergic diseases in 1967, our knowledge about the immunological mechanisms of IgE‐mediated allergies has remarkably increased. In addition to understanding the immune response and clinical symptoms, allergy diagnosis and management depend strongly on the precise identification of ...

Abstract Ticks are the second most important vector capable of transmitting diseases affecting the health of both humans and animals. Amblyomma testudinarium Koch 1844 (Acari: Ixodidae), is a hard tick species having a wide geographic distribution in Asia. In this study, we analyzed the composition of A.

Tick salivary gland extract induces alpha‐gal syndrome in alpha‐gal deficient mice
Alpha‐gal syndrome (AGS) is characterized by delayed hypersensitivity to non‐primate mammalian meat in people having specific IgE (sIgE) to the oligosaccharide galactose‐alpha‐1,3‐galactose and has been linked to tick bites from Amblyomma americanum (Aa) in the U.S.

Sequencing and comparative analysis of the Amblyomma sculptum mitogenome
The mitogenome of Amblyomma sculptum was sequenced, providing important information for understanding the evolutionary relationships among species of the A. cajennense complex. The mitochondrial genome has a circular structure with 37 genes, including 13 coding DNA sequences, two ribosomal RNA genes (12S rRNA and 16S rRNA) and 22 tRNA genes ...

Microhabitat determines uneven distribution of Amblyomma parvum but not of Amblyomma sculptum ticks within forest patches in the Brazilian Pantanal [PDF]
Environmental distribution of the two most abundant ticks in forest areas in the Brazilian Pantanal was evaluated by CO2 traps methodology in the wet season (peak of adult ticks) of 2012 and 2013. Adults of Amblyomma parvum were concentrated inside agglomerates of Bromelia balansae, in the border of forest patches. Adults of Amblyomma sculptum occurred
