| Abstract: | Two regions (Jimma and Dire Dawa) in Ethiopia were investigated for the presence of soft ticks. Although no Ornithodoros spp. ticks were collected during this survey, published records of their existence in Ethiopia were found. An overwhelming infestation of Argas persicus was revealed in a village located adjacent to Dire Dawa. These ticks primarily were feeding on poultry, but were also biting humans. Furthermore, hard ticks were collected from livestock and companion animals in these regions.Collected ticks were assessed for Borrelia by real-time PCR followed by conventional PCR and sequencing to identify species present. A. persicus ticks were found to carry B. anserina in 3 of 40 (7.5%) A. persicus tick pools, whilst hard tick pools yielded 2 of 16 (12.5%) positive for B. theileri. Collectively, these borrelial species and their tick vectors are likely to have an important economic impact of particular relevance to subsistence farmers in Ethiopia. |
