Qinling Mountains locate in central China, is of complex geography, is oneof the richest areas of biodiversity in China, and has a very high ecological zoneadvantages enjoyed a high reputation in the world’s biodiversity protection. Thewild animal species in Qinling area has a unique advantage, many rare andendangered wildlife species, such as giant panda, golden monkey, golden takinand crested ibis et al. are in the region.A total of303rare wild animals and36other wild animals which rescuedfrom the wild field or bred in Wildlife Rescue and Research Center of ShaanxiProvince were investigated with parasitological stool examination, ectoparasitedetection and parasitological full necropsy. A variety of parasitic worm eggs,larvae, and adults, ectoparasites (ticks, lice, etc.), protozoan oocysts wereobtained in rare wild animals. The collected parasite specimens wereidentified according to morphology. The results were as followings.(1) The303first class rare wild animals, including19golden monkeys,22 giant pandas,26golden takins,236crested ibises were investigated in thisresearch. Stool examination method, ectoparasite examination method andcomplete parasitological necropsy method were used to detect the parasites,including worms, eggs, larvae and oocysts et al. The identified parasites belongto17families,18genera and18species, including2protozoa(Eimeria spp. andIsospora sp.),3trematodes(Ogmocotyle indica, Dicrocelium lanceatum,Echinostoma spp.),3cestodes(Moniezia benedeni, Cysticercus tenuicolles,Coenurus cerebralis),7nematodes (Baylisascaris schroederi, Trichocephalussp., Haemonchus contortus, Protostrongylus sp., Bunostomum sp.,Gongylonema pulchrum, Capillaria sp.),2Lice(Trichodectes sp. and Lipeurussp.) and1tick(Haemaphysalis sp.). The results showed that parasitic infectionin salvaged wildlife was more severe than that in captive wildlife. G. pulchrumwas the first time found in golden takin.(2) The parasitological investigation were also carried out for the other36wildlifes, including5gorals,21peacocks,4serows, a wild boar,4wolves, and1roe deer. The parasite eggs, worms and oocysts found in the wild animals wereidentified, which belong to16families,19genera and20species, and theparasite infection rate was100%. Wherein there are2protozoa(Eimeria spp.and Sarcocystis sp.),2cestodes(Moniezia benedeni and Cysticercus tenuicolles),3trematodes(O. sikae, D. lanceatum, D. chinensis),10nematodes(H. contortus, Ostertagia sp., Oesophagostomum asperum, T. gazellae, Metastrongylus apri,Ascaris suum, Heterakis sp., Capillaria sp., Ascaridia columbae, Toxocaracanis)and3ticks(Ixodes sp., Haemaphysalis sp., Dermacentor sp.).
