The infection is caused by an intracellular bacterium Coxiella burnetii. The reservoir of this bacterium is ubiquitous, consisting of many mammals, but also ticks. The present research which took place from October 2017 to October 2020 focused on the analysis of C. burnetii DNA carriage in ticks, on an analyzed sample of 980 tick collections, there were 735 cases positive, i.e. a prevalence of 75%. ELISA and real-time PCR methods were used for data analysis. Species like Amblyomma, Rhipicephalus (boophilus), Rhipicephalus and Hyalomma are found in Kindia (Lower Guinea). In the prefectures of Beyla, Lola and N'Zérékoré (Guinée Forestičre), Rh decoloratus, Am variegatum and Rh (boophilus) geigyi are found. The presence of this pathogen constitutes a threat to human and animal health in these investigated areas, and must be taken into account in the biological diagnosis of Q fever.
