Abstract

We report a clinical case of spotted fever group rickettsiosis acquired in Sao Paulo, Brazil. Definitive diagnosis was supported by seroconversion between acute-phase and convalescent-phase serum samples. Molecular analysis of skin samples indicated the agent was a novel spotted fever group strain closely related to Rickettsia africae, R. parkeri, and R. sibirica.

Molecular phylogenetic analysis of Rickettsia sp. strain Atlantic rainforest detected in a patient from the State of São Paulo, Brazil. A) A total of 740 unambiguously aligned nucleotide sites of the rickettsial outer membrane protein (ompB) gene were subjected to analysis. B) A total of 463 unambiguously aligned nucleotide sites of the rickettsial ompA gene were subjected to analysis. Bootstrap values >50% are shown at the nodes. Numbers in brackets are GenBank accession numbers. The strain isolated in this study is indicated in boldface. Scale bars indicate nucleotide substitutions per site.
