Parasite research of wildlife is important for their conservation and management, as well for to invesitgate effects of zoonotic parasites on the public health. This study was aimed to investigate patterns of intestinal parasitic infection in Taiwanese macaque groups with differential degree of interactions with humans.Effectsof age, sex, social dominance and matrilineal kinship with parasitic infection patterns were allowed to be examined with fecal analysis on samples of known individuals. Differential infection patterns resulted from fecal sampling mathods were revealed and discussed. From September 2008 to September 2009, Fresh feces were collected monthly from known individuals in one group at Fushan experimental forest and three groups at Mt. Chai. Feces were preserved in 10％formalin for further fecal analysis. A total of 605 feces were collected and analyzed for parasitic infection. In total, 11 parasites species were discovered at both sites, including eight nematodes (Trichuris sp., Strongyloides sp., Oesophagostomum sp., Ascaris sp., Ternidens sp., Trichostrongylus sp., Capillaria sp. and Enterobius sp.), two prozoans (Balantidium coli and Entamoeba coli), and one platyhelminthes (Berttiella sp.). The parasite species richness, prevalence and mean intensity of infection of adult macaques were significantly higher than those of juveniles at both sites. No significant difference in the parasitic infection between sexes. Individuals in a maternaline harbored similar parasite species, which were different from individuals of other matrilines in the Fushan group. On average, 2.63 ± 0.69 parasite species were recovered per feces. However, the mean numbers of parasites infected in adult females were 5.62±0.87. It suggested that enough samples from known individuals collected in a long period of time were needed in order to reveal a full picture of parasitic infection pattern of macaque individuals and groups. The prevalence and mean intensity of most intestinal parasites were higher in Fushan macaque group than those at Mt. Chai. Associations between the mean abundance of parasites and the temperature were not in common in macaques livinging in the two study sites. Most of the parasite genera infecting the macaques have zoonotic species. It cannot be ruled out the possible influence of zoonotic infection through frequent macaque-human interactions to the public health. However, further research is needed to identify the parasites to the species level.
