Amblyomma sculptum (Amblyomma cajennense complex) tick population maintained solely by domestic pigs
Veterinary Parasitology: Regional Studies and Reports, 2016In Brazil Amblyomma sculptum from Amblyomma cajennense complex is a tick species with a rather broad distribution encompassing the Cerrado Biome and devastated areas of the Atlantic rainforest. This species is also the major vector to humans of Rickettsia rickettsii, agent of the Brazilian spotted fever.

Cancer is one of the most troubling diseases and is becoming increasingly common. Breast cancer has a high cure rate when diagnosed early, but when diagnosed late, treatment is frequently painful, devastating and unsuccessful. The search for new treatments that are more effective and less harmful has led to several substances and biomolecules from ...

A silicon-membrane based artificial feeding system for Amblyomma sculptum nymphs
Experimental and Applied AcarologyThe aim of the study was to establish an artificial feeding system (AFS), based on silicon membranes, for Amblyomma sculptum nymphs and compare it to classical feeding systems using laboratory animals. Three cohorts of 60 nymphs were fed on a rabbit, calf, and with the newly established AFS using prewarmed (38 °C) defibrinated bovine blood.

Report of Amblyomma sculptum in a House in a Rickettsia rickettsii Circulation Area
Vector-Borne and Zoonotic Diseases, 2021Amblyomma sculptum is a tick that has medical and veterinary importance as, in Brazil, it is the main vector of Rickettsia rickettsii, a disease affecting humans. The presence of ticks was observed outside a residence in a peri-urban area of the Atlantic Forest region in Brazil, as well as on two dogs that lived there. Eighteen A.

Novel record of a tick Amblyomma sculptum with detection of piroplasm Rangelia vitalii DNA
Veterinary Parasitology: Regional Studies and Reports, 2018Rangelia vitalii is the protozoan responsible for a febrile tick-borne disease known as "Nambiuvú" or "bleeding plague." The only competent vector of this protozoan recognized in Brazil is the tick Amblyomma aureolatum. The aim of this study was to identify R.

This study evaluated the acaricidal activity of the methanol extract of Acmella oleracea with 0.187% of spilanthol against immature stages of Amblyomma sculptum. The packet test was used to evaluate the extract's activity on unengorged larvae and nymphs, testing concentrations of 0.4 to 50 mg/mL for larvae and 12.5 to 200.0 mg/mL for nymphs.

Analysis of Amblyomma sculptum haplotypes in an area endemic for Brazilian spotted fever.
Medical and veterinary entomology, 2017Amblyomma sculptum (Ixodida: Ixodidae) Berlese, 1888, a member of the Amblyomma cajennense complex, is the major vector of Brazilian spotted fever (BSF) in southeastern Brazil. In this study, the genetic diversity of A. sculptum populations in the state of Rio de Janeiro (RJ), Brazil, was investigated because genetic variability in tick populations may
