In this research, we identified and counted infectious ticks in died six gazelles Procapra przewalskii in Qinghai Lake area. All the six gazelles were infected with Dermacentor abaensis (Fig. 1) in their head-neck and waist-back with an average number of 14 at each died body (Table 1). Here, we provided some measures to control the tick density in the areas used by the gazelles and other ungulate species.
