Introduction:
Exploration of endoparasites in wildlife is an important approach to understand how animals interact with environment. The processes of Carnivora infected endoparasites were closely related to foods (preys) or touching (habits). In the process of life cycle of parasites, it will be sight the reciprocity between parasites-host with environment. Little is known about parasites infecting wildlife in Taiwan. There has been only a brief report by Myers and Kuntz in 1964 about small Chinese civets. In this study, we tried to clarify small Chinese civets that were a native medium-sized carnivore species in Taiwan and treat to the interrelation of wildlife-environment. Fecal samples of small Chinese civet were collected for three consecutive days monthly during August 2006 to October 2007 in the range of Fushan Experimental Forest (24°46’N, 121°34’E) in Northern Taiwan. The average temperature ranged from 17.1℃ to 30.2℃ during the collected time. There were 444 fecal samples of small Chinese civet has been collected and analyzed, among which 381 samples were used to conduct EPG analysis (egg count per gram of feces). There were 16 parasites recovered by detection on their adult worm, egg, larva and/or oocyst, including 11 helminthes and 5 protozoa. Among which, Monocystis spp., Tetrameres sp., and Passalurus sp. were presumed that were infected prey species of the civet and non-infectious to the civet. The prevalence of parasitic infections was 84% from the fecal samples (n=381). Top six prevalent of parasite species were Capillaria sp. (57.5%), Strongyloides sp. (37.0% for larva), Ancylostoma sp. (36.2%), Monocystis spp. (33.1%), Toxocara paradoxura (30.7%) and Trichuris sp. (9.5%). A total of 13 intestinal parasite species that are infectious small Chinese civet were recovered from the fecal samples, among which adult worms of two species, Toxocara paradoxura and Mesocestoides litteratus, were new record for Taiwan and were not reported. Although Monocystis spp. is non-infectious to the small Chinese civet, It was also new record in Taiwan at this observe. In patterns of parasitic infection, multiple-parasite infections were found in more fecal samples (76.9% of infected samples) than singular-parasite. Two parasite species types were recovered in the highest percentage of the multiple-infected fecal samples (40.7%, 100 samples). Capillaria sp. and Strongyloides sp. (larva) were recovered together in the highest number of samples in two parasite species types of multiple- parasite samples (19%). The species richness of parasites in one fecal sample reached as high as nine species, including Paragonimus sp., Mesocestoides litteratus, Toxocara paradoxura, Ancylostoma sp., Capillaria sp., Trichuris sp., Siprocerca sp., Strongyloides sp. and Monocystis spp. Life histories of these parasitic species almost related to the soil. It was fit to the behavior of small Chinese civet, that move on the ground.
We also detected the oocysts of Cryptosporidium sp., Cyclospora sp., and Isospora sp. in fecal smears that were stained with Modified Ziehl-neelsen stain. The additional reminiscent, Cryptosporidium sp. and Cyclospora sp. has been known to infect humans and cause disease, especially for people who have immunodeficiency. We need to pay close attention to parasites information from wild and monitoring of wildlife diseases.
