中文摘要:
      人工繁育是当前我国保护野生林麝(Moschus berezovskii)资源的主要手段之一,但在林麝种群复壮的过程中,消化道寄生虫病始终威胁着林麝的健康。为探究林麝消化道寄生虫群落对不同扰动策略的响应,本研究分别使用复合药阿苯达唑伊维菌素粉和单一成分药阿维菌素粉去除林麝体内线虫和绦虫,监测林麝其他寄生虫和群落动态变化。选取60只雄性林麝,随机分为3组,分别为阿苯达唑伊维菌素用药组(20只)、阿维菌素用药组(20只)和未做任何处理的对照组(20只),并连续采集8周用药组和对照组林麝的新鲜粪便。基于改良的Wisconsin粪便虫卵漂浮计数法检测粪便中的虫卵和卵囊。对实验结果进行Kruskal-Wallis检验、Wilcoxon秩检验、Mann Whitney检验和双因素方差分析。研究结果显示,对照组和阿苯达唑伊维菌素用药组林麝的寄生虫感染均为混合感染,球虫为优势物种,其负载量显著高于线虫和绦虫(P < 0.05),阿维菌素用药组林麝仅感染球虫。药物扰动后,两用药组林麝的球虫流行率、平均感染强度均高于对照组,但线虫流行率均低于对照组(27.15%,42.15%)。此外,用药后,阿苯达唑伊维菌素用药组林麝先于阿维菌素用药组再次感染线虫和绦虫。通过比较用药组和对照组林麝寄生虫的群落动态变化,表明林麝消化道寄生虫感染现象较为普遍,多重感染中球虫和蠕虫存在竞争关系,复合药物阿苯达唑伊维菌素粉对林麝寄生虫群落的扰动程度更大,林麝寄生虫群落恢复能力与扰动程度成正比。建议林麝人工繁育基地加强科学性和计划性驱虫,并持续性开展林麝寄生虫感染的监测工作。
英文摘要:
      Captivity is one of the main methods to protect wild Forest Musk Deer (Moschus berezovskii) in China. However, parasitic disease is the main factor limiting the reproduction of captive individuals in the process of population rejuvenation. To investigate the response of parasite community in the digestive tract to different perturbations, we performed a perturbation experiment in captive Forest Musk Deer, by using compound drug albendazole ivermectin powder and single drug avermectin powder to suppress macroparasites, and monitored the consequences of dynamic changes in its community and other parasite species. We randomly selected 60 adult male Forest Musk Deers and divided them into different treatment groups: albendazole ivermectin group (20 ind), avermectin group (20 ind), and control group (20 ind), the control group without any treatment. We collected fresh fecal samples after anthelmintic disturbance for eight weeks for the experiment of egg floatation and count of eggs and oocysts based on Wisconsin’s egg counting method. Then we did the Kruskal-Wallis test, Wilcoxon test, Mann Whitney test, and Two-way ANOVA test of the data. The results showed that the parasite infection of Forest Musk Deer was mixed in both control group and albendazole ivermectin group after anthelmintic treatment, with coccidia being the dominant parasite taxa. The number of coccidia was higher than that of nematode or cestode (P < 0.05) (Fig. 1). In the avermectin group, only coccidia was found (Fig. 1). The prevalence and average infection intensity of coccidia in treatment group were higher than those in the control group after interference, while treated Forest Musk Deers had a lower (27.15%) nematode infection rate compared with control individuals (42.15%) (Fig. 1, Fig. 2). The reinfection of nematode and cestode in albendazole ivermectin group was quicker than that in avermectin group after interference (Fig. 4, Fig. 5). Therefore, this study has proved that parasitic infection of digestive tract is common in Forest Musk Deer, and that competitive interactions between multiple parasite infections exist in the digestive tract. The analysis of community dynamics indicated that parasite communities in the digestive tract have diverse responses to different disturbance strategies, and that the compound medicine can cause greater perturbation to the coccidia and the recovery ability of parasite community is in proportion to perturbation degree. These results have provided a rare and clear experimental demonstration of interactions between helminths and co-infecting parasites in wild vertebrates. We suggested that the Forest Musk Deer breeding center should strengthen scientific and planned deworming, and continuously monitor parasite infection.
