rickettsia felis in ctenocephalides spp. fleas, brazil.	in june 2000, suspected cases of brazilian spotted fever (bsf) occurred in coronel fabriciano municipality, minas gerais state, brazil. pooled fleas collected near two fatal cases contained rickettsial dna. the nucleotide sequence alignment of the 391-bp segment of the 17-kda protein gene showed that the products were identical to each other and to the r. felis 17-kda gene, confirming circulation of r. felis in brazil.	2002	11927031
old and new human rickettsiosis in minas gerais state, brazil.	the authors describe cases of brazilian spotted fever (bsf) diagnosed in minas gerais state, brazil, by the minas gerais public health laboratory, ezequiel dias foundation from 1995 to 2004. in addition they present three cases of human rickettsia felis rickettsiosis from minas gerais diagnosed in france in 1999, and the first two suspected cases of human monocytic ehrlichiosis (hme) diagnosed in ezequiel dias foundation in 2001. in both cases a differential diagnose was made with bsf.	2005	16481542
rickettsia in synanthropic and domestic animals and their hosts from two areas of low endemicity for brazilian spotted fever in the eastern region of minas gerais, brazil.	the aim of this study was to understand the current epidemiology of rickettsial diseases in two rickettsial-endemic regions in brazil. in the municipalities of pingo d'agua and santa cruz do escalvado, among serum samples obtained from horses and dogs, reactivity by immunofluorescent assay against spotted fever group rickettsiae was verified. in some serum samples from opossums (didelphis aurita) captured in santa cruz do escalvado, serologic response against rickettsiae was also verified. polym ...	2010	21118939
amblyomma sculptum: genetic diversity and rickettsias in the brazilian cerrado biome.	amblyomma sculptum (ixodida: ixodidae) berlese, 1888 is the most important tick vector in brazil, transmitting the bioagent of the most severe form of spotted fever (sf) in part of the cerrado (in the states of minas gerais and são paulo). in another part of the cerrado (central-west region of brazil), a milder form of sf has been recorded. however, neither the rickettsia nor the vector involved have been characterized. the aim of the current study was to analyse genetic variation and the presen ...	2017	28752684
