BACKGROUND: Theileria and Anaplasma are especially important emerging tick-borne pathogens of animals and humans. Molecular surveys and identification of the infectious agents in Mongolian gazelle, Procapra gutturosa are not only crucial for the species’ preservation, but also provide valuable information on parasite and bacterial epidemiology. FINDINGS: A molecular surveillance study was undertaken to assess the prevalence of Theileria spp. and Anaplasma spp. in P. gutturosa by PCR in China. Theileria luwenshuni, A. bovis, A. phagocytophilum, and A. ovis were frequently found in P. gutturosa in China, at a prevalence of 97.8%, 78.3%, 65.2%, and 52.2%, respectively. The prevalence of each pathogens in the tick Haemaphysalis longicornis was 80.0%, 66.7%, 76.7%, and 0%, respectively, and in the tick Dermacentor niveus was 88.2%, 35.3%, 88.2%, and 58.5%, respectively. No other Theileria or Anaplasma species was found in these samples. Rickettsia raoultii was detected for the first time in P. gutturosa in China. CONCLUSIONS: Our results extend our understanding of the epidemiology of theileriosis and anaplasmosis in P. gutturosa, and will facilitate the implementation of measures to control these tick-borne diseases in China.
