    Abstract:

    Objective To analyze and understand the epidemic situation of intestinal helminthe infection in wild tree shrews (Tupaia belangeri Chinensis), and to provide useful reference and support for prevention and treatment of parasitic infection in tree shrews. Methods 203 wild tree shrews were used in this study. Stool ova in the smear from fresh feces and after incubation were observed and identified by routine microscopic examination. Cestodes were observed in press slide after fixation and staining, and nematodes were observed under a stereoscope after clearing. The ova were identified with corresponding adult parasites. Results In this survey, we found the total prevalence rate of intestinal helminthes in this wild tree shrew population was 75.86%, mainly including three kinds of important parasites, namely, Hymenolepis diminuta 27.67%, Rictularia sp. 30.06%, and Strongyloides stercoralis 51.52%, respectively. Mixed infection rate of the three species was 4.55%. For Rictularia sp. and Strongyloides stercoralis, embryonated eggs were often observed in their fresh feces. Conclusions Intestinal helminth infection rate is rather high in the wild tree shrews. Quarantine inspection is necessary for new intake. Different control measures and surveillance should be taken to control the dissemination of intestinal helminth infection in tree shrews.
