Revisiting Brazilian Spotted Fever Focus of Caratinga, Minas Gerais State, Brazil

Annals of the New York Academy of Sciences, 2006
Abstract:  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 ...

Brazilian Spotted Fever: A Case Series from an Endemic Area in Southeastern Brazil

Annals of the New York Academy of Sciences, 2006
Abstract:  Brazilian spotted fever (BSF) is the most important tick‐borne disease in Brazil and is caused by Rickettsia rickettsii and transmitted by the Ixodid tick Amblyomma cajennense, its main vector. We present epidemiologic aspects of a case series of patients admitted to the Hospital das Clínicas da UNICAMP from 1985 to 2003 with a confirmed ...

Analysis of Amblyomma sculptum haplotypes in an area endemic for Brazilian spotted fever.

Medical and veterinary entomology, 2017
Amblyomma 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
