Piroplasmids (order Piroplasmida) are a diverse group of tick-borne protozoa that may cause disease in animals and occasionally humans. Novel Piroplasmida clades species have been found wild from Brazil based on the phylogenetic assessment near-complete 18S rRNA, mitochondrial heat-shock protein genes. For instance, putative novel Babesia has detected capybaras Amblyomma ticks three Brazilian states. The present work aimed to describe, using assessments distinct molecular markers, this...
Brazilian spotted fever is a tick-borne disease caused by the bacterium Rickettsia rickettsii, whose main vector in Brazil tick Amblyomma sculptum. Amplifying hosts are essential for perpetuation of this population as they can be sources infection during bacteremic periods. Recent studies demonstrated ability suids (Sus scrofa) to sustain populations A. sculptum, one species found parasitizing wild boars midwestern and southeastern regions Brazil. In study, were experimentally infected with...
This study sought to investigate the presence of anti-Rickettsia spp. antibodies in georeferenced serum samples from equids across all regions state Goiás, while also presenting variables that indicate risk factors for circulation rickettsiae, and evaluating rickettsial DNA ticks collected surrounding environment municipalities Uruaçu Porangatu, located northern region state. A total 1156 equid provided by Goiás Agricultural Defense Agency (Agrodefesa) were analyzed against 4 Rickettsia...
Amblyomma sculptum is a relevant tick species from One Health perspective, playing an important role as vector of Rickettsia rickettsii, the main agent spotted fever rickettsiosis in Brazil. In this study, we evaluated susceptibility two A. populations Goiás state (midwestern Brazil) to different acaricides. The first population (GYN strain) originated experimental farm, where ticks are annually exposed second (PNE was collected national park (Emas National Park), had not been Immersion...

Abstract Background The tick Amblyomma cajennense sensu stricto (s.s.) frequently parasitizes animals and humans in the Amazon biome, addition to being a vector of Rickettsia amblyommatis . In present study, we evaluated population dynamics A. s.s. degraded area presence rickettsial organisms this population. Methods study was carried out rural Santa Inês municipality (altitude: 24 m), Maranhão state. Ticks were collected from environment during consecutive months, June 2021 May 2023. region...
