Molecular Survey of Tick-Borne Pathogens Reveals Diversity and Novel Organisms With Veterinary and Public Health Significance in Wildlife From a National Nature Reserve of China
Wildlife is involved in the maintenance and transmission of various tick-borne pathogens. The objective of the present study was to determine the occurrence and diversity of tick-borne pathogens in free-ranging wild animals collected from Tangjiahe National Nature Reserve of China. Blood or liver samples from 13 wild animals (5 takin, 3 Himalayan goral, 3 Reeves' muntjac, 1 forest musk deer, and 1 wild boar) were collected and screened for piroplasm, Anaplasma spp., Ehrlichia spp., and spotted fever group (SFG) rickettsiae by PCR-based on different gene loci. Three Theileria species, a potential novel Theileria parasite (Theileria sp. T4) and two Anaplasma species were identified in those wildlife. Theileria capreoli was found in Himalayan goral, Reeves' muntjac, and forest musk deer; Theileria luwenshuni, Theileria uilenbergi, and a potential novel, Theileria parasite (Theileria sp. T4), were identified in takin. Meanwhile, Anaplasma bovis was identified in Himalayan goral, takin, Reeves' muntjac, forest musk deer, and wild boar; Anaplasma phagocytophilum and related strains was found in takin, Reeves' muntjac, and forest musk deer. All wildlife included in this study was negative for Babesia, Anaplasma ovis, Anaplasma marginale, Ehrlichia, and SFG rickettsiae. Moreover, coinfection involving Theileria spp. and Anaplasma spp. was observed in eight wild animals. This study provided the first evidence of tick-borne pathogens in free-ranging wild animals from the nature reserve, where contact between domestic and wild animals rarely occurs.
