Epidemiology of rocky mountain spotted fever in Brazil, 2010-2020

Rocky Mountain spotted fever is a tick-borne rickettsiosis. The main clinical signs and symptoms are fever, severe headache, rashes and myalgia. It is considered difficult to diagnose and underreported. The study aims to descriptively analyze the epidemiology of cases of Rocky Mountain spotted fever in B...

In vitro acaricidal activity of different ectoparasiticide classes against Amblyomma sculptum larvae

Abstract Zoonoses are major causes of morbidity and mortality worldwide. Among them, Brazilian Spotted Fever (BSF) is an important one that occurs in some regions of South America and can be transmitted by the "star tick" Amblyomma sculptum. Application of acaricides against the larval stage is important...

Integrated tick control on a farm with the presence of capybaras in a Brazilian spotted fever endemic region

Abstract Ticks of the Amblyomma cajennense complex present high infestation rates. These ticks transmit the bacterium Rickettsia rickettsii, which causes Brazilian Spotted Fever. For this reason, an integrated tick control system was adopted on a farm in the municipality of Itu, state of São Paulo. On t...

Serosurvey of Rickettsia spp. in cats from a Brazilian spotted fever-endemic area

Abstract Rickettsia spp. bacteria are responsible for tick-borne diseases worldwide, mostly maintained by rickettsial amplifiers capybaras in Brazilian endemic areas. The campus of the University of São Paulo, in southeastern Brazil, is an area endemic for Brazilian spotted fever (BSF), with high densit...

Brazilian spotted fever prevention through a nonlethal capybara population control strategy

Abstract INTRODUCTION: Brazilian spotted fever (BSF), a lethal tick-borne Rickettsioses (2000 - 2018 >600 human deaths) involving synanthropic capybara as host. METHODS: We introduced an alternative to mitigate human-capybara conflicts and epidemiologic concerns of BSF. Complex aspects like transm...
