  abstract = {{R}ickettsia are obligate intracellular bacteria often associated with ticks and best known for causing human diseases (rickettsiosis), including typhus fever and sporadic cases of serious infection. {I}n this study, we conducted a large survey of ticks in {F}rench {G}uiana to understand the overall diversity of {R}ickettsia in this remote area largely covered by dense rainforests. {O}ut of 819 individuals (22 tick species in six genera), 252 (30.8%) samples were positive for {R}ickettsia infection. {M}ultilocus typing and phylogenetic analysis identified 19 {R}ickettsia genotypes, but none was 100% identical to already known {R}ickettsia species or strains. {A}mong these 19 genotypes, we identified two validated {R}ickettsia species, {R}ickettsia amblyommatis (spotted fever group) and {R}ickettsia bellii (bellii group), and characterized a novel and divergent {R}ickettsia phylogenetic group, the guiana group. {W}hile some tick hosts of these {R}ickettsia genotypes are among the most common ticks to bite humans in {F}rench {G}uiana, their potential pathogenicity remains entirely unknown. {H}owever, we found a strong association between {R}ickettsia genotypes and their host tick species, suggesting that most of these {R}ickettsia genotypes may be nonpathogenic forms maintained through transovarial transmission.},
