Ixodid ticks were collected and identified from 8 wild carnivore species in Phu Khieo Wildlife Sanctuary, northeastern Thailand. Six tick species belonging to 4 genera were recovered and identified from 132 individuals. These included Amblyomma testudinarium (n = 36), Haemaphysalis asiatica (n = 58), H. hystricis (n = 31), H. semermis (n = 3), Rhipicephalus haemaphysaloides (n = 3), and Ixodes granulatus (n = 1). Leopard cats (Prionailurus bengalensis) (n = 19) were infested with 4 tick species, whereas yellow-throated marten (Martes flavigula) (n = 4), clouded leopard (Neofelis nebulosa) (n = 2), and dhole (Cuon alpinus) (n = 1) were infested with 3 tick species, Asiatic golden cat (Catopuma temmincki) (n = 2) with 2 species, and marbled cat (Pardofelis marmorata), binturong (Arctictis binturong), and large Indian civet (Viverra zibetha) each infested with 1 species. This information contributes to the knowledge available on the ectoparasites of wild carnivores in Southeast Asia.
