*The tick was removed in 2014 from the nostril of a woman who returned home to Spain after visiting Lopé National Park in Gabon. NA, not available.
†Percentages of identity with sequences of Rickettsia sp. Davousti have been also included when available due to the high level of similarity with our sequences.
