Basic reproduction number for the Brazilian Spotted Fever
Journal of Theoretical Biology, 2018 Brazilian Spotted Fever (BSF) is an emerging and lethal disease in South America which basic reproduction number (R0) is unknown. Calculating R0 for this disease is crucial to design control interventions and prevent human deaths. BSF endemic areas are related to the presence of capybaras Hydrochoerus hydrochaeris, amplifier hosts of Rickettsia ...

Features of Brazilian spotted fever in two different endemic areas in Brazil
Ticks and Tick-borne Diseases, 2012 Brazilian spotted fever (BSF) caused by Rickettsia rickettsii is the most important rickettsiosis and the only reportable tick-borne disease in Brazil. In Brazil, the hard tick Amblyomma cajennense is the most important BSF vector; however, in São Paulo State, A. aureolatum was also recognized as a vector species in remaining Atlantic forest areas near

Temporal trends and spatial distribution of Brazilian spotted fever in Brazil
Journal of Travel Medicine, 2023Brazilian Spotted Fever (BSF) is a severe tick-borne disease in Brazil’s south and southeast regions. We examined temporal trends and spatial distribution of BSF cases and deaths. There were stable incidence and mortality rates, decreasing case fatality, and distinct spatial clusters, highlighting the need for ongoing surveillance and prevention ...

Mapping Brazilian spotted fever: Linking etiological agent, vectors, and hosts
Acta Tropica, 2020Brazilian spotted fever (BSF) is a highly lethal disease in southeastern Brazil. BSF is caused by the bacterium Rickettsia rickettsii and is transmitted by the bites of the tick of the genus Amblyomma. The spatial distribution of BSF risk areas is not well known in the country given the complexity of the transmission cycle.

Brazilian spotted fever: Real-time PCR for diagnosis of fatal cases
Ticks and Tick-borne Diseases, 2012 Suspicion of Brazilian spotted fever (BSF) should occur in endemic regions upon surveillance of the acute febrile icteric hemorrhagic syndrome (AFIHS). However, limitations associated with currently available laboratory tests pose a challenge to early diagnosis, especially in fatal cases.

Serological Evidence of Human Coinfection by Brazilian Spotted Fever and Bartonellosis
International Journal of Clinical Medicine, 2016 Brazilian spotted fever and bartonellosis are zoonotic, emerging and under diagnosed diseases. Pets may be co-infected by multiple pathogens and become transmissions sources to humans. The study reports the first case of active co-infection by Brazilian spotted fever and bartonellosis based on serological evidence.

Revisiting Brazilian Spotted Fever Focus of Caratinga, Minas Gerais State, Brazil
Annals of the New York Academy of Sciences, 2006Abstract: We revisited a Brazilian spotted fever focal area in Minas Gerais state, Brazil, in 2002, and performed a serologic survey in dogs and cats. The results of this survey are compared with the survey made 10 years before. The possible efficacy of vector control measures adopted in this area and the role of dogs and horses as sentinels of ...

Rickettsia parkeri in Amblyomma dubitatum ticks in a spotted fever focus from the Brazilian Pampa
Acta Tropica, 2017 Spotted fever is an acute febrile illness, which is considered severely underreported and misdiagnosed in the Brazilian Pampa, caused by tick-borne Rickettsiae. Here, we report an eco-epidemiological investigation of Rickettsia spp. in ticks from a spotted fever focus in Toropi, southern Brazil.
