Abstract Background In 2022, fluralaner was launched on the market for use in control of cattle tick Rhipicephalus microplus after showing 100% efficacy registration trials against causative agents fever (TFAs). The aim present study to determine whether a strategic regimen R. using (FLU) Holstein calves grazing tropical region would alter enzootic stability status fever, triggering outbreaks these animals up 22 months age. Methods this study, group treated with FLU compared currently being...
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...
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...

Among the parasitic and infectious diseases affecting cats, those caused by vector-borne pathogens deserve attention due to their ability cause nonspecific clinical signs clinicopathological abnormalities. We studied presence of
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...
The tick Amblyomma cajennense sensu stricto (A. s.s.) frequently parasitizes animals and humans in the Amazon biome, addition to being a vector of Rickettsia amblyommatis. In present study, we evaluated both population dynamics A. s.s. degraded area biome presence rickettsial organisms this population. study was carried out rural Santa Inês municipality (altitude: 24 m a.s.l.), Maranhão state, Brazil. Ticks were collected from environment for consecutive months, June 2021 May 2023. region is...
This study was carried out from February 2020 to September 2021 in Parque Nacional das Emas (PNE), a national park located the Cerrado biome, midwestern Brazil, as well surrounding rural properties. Serum and tick samples were collected dogs, terrestrial small mammals, humans. Ticks also environment. Dogs infested with Rhipicephalus linnaei adults, whereas mammals by immature stages of Amblyomma spp., triste, dubitatum, coelebs. vegetation belonged several species genus Amblyomma, including...
