The burden of gastrointestinal parasites in zoo animals has serious implications for their welfare and the health of veterinarians and visitors. Zhuyuwan Zoo is located in the eastern suburb of Yangzhou city in eastern China, in which over 40 species of zoo animals are kept. In order to understand the infection status of GI parasites in Zhuyuwan Zoo, a total of 104 fresh fecal samples collected randomly from birds ( = 19), primates ( = 19), and non-primate mammals ( = 66) were analyzed using the saturated saline flotation technique and nylon sifter elutriation and sieving method for eggs/oocysts, respectively. Two species were molecularly characterized. The results showed that the overall prevalence of parasitic infection was 42.3% (44/104). The parasitic infection rate in birds, primates, and non-primate mammals were 26.3% (5/19), 31.6% (6/19), and 50.0% (33/66), respectively. A total of 11 species of parasites were identified, namely, Trichostrongylidae, sp., spp., spp., sp., , , , spp., spp., and spp. spp. eggs were first detected from the captive Père David's deer, and spp. eggs were first reported from sika deer in zoo in China. A sequence analysis of ITS-2 and 1 showed that the eggs isolated from the African lion ( Linnaeus, 1758) were , and the eggs from the brown bear ( Linnaeus, 1758) were . The public health threat posed by these potential zoonotic parasitic agents requires attention. These results lay a theoretical foundation for prevention and control of wild animal parasitic diseases at zoos in China.
动物园动物胃肠道寄生虫的负担对它们的健康福利以及兽医和游客的健康都有严重影响。茱萸湾动物园位于中国东部扬州市东郊，饲养着40多种动物园动物。为了解茱萸湾动物园胃肠道寄生虫的感染状况，分别采用饱和盐水漂浮法和尼龙筛淘洗筛分法对随机采集的104份新鲜粪便样本进行分析，这些样本分别来自鸟类（n = 19）、灵长类动物（n = 19）和非灵长类哺乳动物（n = 66）。对两种寄生虫进行了分子特征分析。结果显示，寄生虫感染的总体患病率为42.3%（44/104）。鸟类、灵长类动物和非灵长类哺乳动物的寄生虫感染率分别为26.3%（5/19）、31.6%（6/19）和50.0%（33/66）。共鉴定出11种寄生虫，即毛圆科、 属、 属、 属、 属、 属、 属、 属、 属、 属和 属。 属虫卵首次在圈养的麋鹿中检测到， 属虫卵首次在中国动物园的梅花鹿中报道。ITS-2和1的序列分析表明，从非洲狮（Linnaeus，1758）分离出的虫卵为 属，从棕熊（Linnaeus，1758）分离出的虫卵为 属。这些潜在的人畜共患寄生虫病原体对公共卫生构成的威胁需要引起关注。这些结果为中国动物园野生动物寄生虫病的防控奠定了理论基础。
