Protozoans of Entamoeba spp. are one of the most common enteric parasites that infect humans and diverse animals including deer.
However, data regarding the prevalence and species/genotypes of Entamoeba spp. in deer in China is scarce. This study investigated the prevalence and species distribution of Entamoeba spp. in sika deer (Cervus nippon) in Anhui Province.
In our survey, 336 fecal samples were collected from five sika deer farms in different regions of Anhui Province. All samples were examined for the presence of Entamoeba spp. by PCR and phylogenetic analysis of the conserved 18S rRNA gene.
106/336 (31.5%) fecal samples were positive for Entamoeba spp. A statistically significant difference in the prevalence of Entamoeba spp. infection was observed between sampling farms (p < 0.001), and the prevalence of Entamoeba spp. in male and female sika deer showed no significant difference (p > 0.05). Sequence and phylogenetic analysis revealed the single species, E. bovis, was identified in this study.
This is the first report about the identification of E. bovis in farm-raised sika deer in China, and these results expand our understanding of host range and species distribution of Entamoeba spp. in ruminants.
内阿米巴属原生动物是最常见的肠道寄生虫之一,可感染人类及包括鹿在内的多种动物。
然而,关于中国鹿体内内阿米巴属的流行情况及种类/基因型的数据稀缺。本研究调查了安徽省梅花鹿(Cervus nippon)体内内阿米巴属的流行情况及种类分布。
在我们的调查中,从安徽省不同地区的五个梅花鹿养殖场采集了336份粪便样本。通过PCR及对保守的18S rRNA基因进行系统发育分析,检测所有样本中是否存在内阿米巴属。
106/336(31.5%)份粪便样本内阿米巴属呈阳性。在各采样养殖场之间,内阿米巴属感染率存在统计学显著差异(p < 0.001),且雄性和雌性梅花鹿的内阿米巴属感染率无显著差异(p > 0.05)。序列和系统发育分析显示,本研究中鉴定出单一物种——牛内阿米巴。
这是中国首次关于养殖场养殖梅花鹿体内牛内阿米巴鉴定的报告,这些结果拓展了我们对反刍动物体内内阿米巴属宿主范围及种类分布的认识。
