Rickettsia are obligate intracellular bacteria living in arthropods. They occationally cause diseases in humans. To understand their pathogenicity, physiologies and evolutionary mechanisms, we are sequencing different species of Rickettsia. Up to now we have determined the genome sequences of R. conorii, R. felis, R. bellii, R. africae, and R. massiliae. The RicBase aims to organize the genomic data to assist followup studies of Rickettsia.
