Ticks and tick-borne diseases in the Middle East.
Abstract This expert opinion focuses on the diversity and distribution of ticks and tick-borne pathogens in the Middle East. From 12 countries in the Middle East where reports and articles were published, a total of 136 species of ticks have been reported. Of these, 111 species belong to the family Ixodidae and 25 species belong to the Argasidae. Reported species of the Ixodidae belong to eight genera (Hyalomma, 25; Rhipicephalus, 23; Haemaphysalis, 22; Ixodes, 20; Amblyomma, 10; Dermacentor, 6; Boophilus, 4; and Aponomma, 1 species), while the Argasidae belong to five genera (Ornithodoros, 13; Argas, 8; Alveonasus, 2; Carios, 1; and Otobius, 1 species). Based on the results of available reports, it seems that species belonging to the genera Hyalomma, Rhipicephalus, Haemaphysalis, Ixodes and Ornithodoros have the highest species diversity in the Middle East.
