摘要: Intestinal protozoa Eimeria and Entamoeba can infect many animal species including alpacas. However, data on the prevalence and pathogenicity of species of the two genera Eimeria and Entamoeba in alpacas in China is scarce. The current study was carried out to investigate the prevalence of Eimeria and Entamoeba in alpacas in two cities (Taiyuan and Xinzhou) in Shanxi Province, northern China, using PCR-based approaches. Eimeria spp. were only found in Taiyuan city, and the overall prevalence was 1.64%. All samples collected from male alpacas were PCR-negative for Eimeria. Four Eimeria-positive samples were tested positive as Eimeria lamae. The molecular prevalence of Entamoeba in alpacas was 18.03% (66/366), including 16.39% (50/305) in alpacas from Taiyuan city and 26.23% (16/61) from Xinzhou city, respectively. The Entamoeba prevalence in male alpacas (25.00%) was significantly higher than that in female alpacas (15.69%). Entamoeba bovis was the predominant species, and no Entamoeba histolytica infection was detected. Nine unique SSU rRNA gene sequences of Entamoeba were obtained which formed a new cluster. The results showed that sex and location might be the risk factors associated with prevalence of Eimeria spp., and sex might be the risk factor associated with prevalence of Entamoeba spp.. This is the first report of Entamoeba in alpacas worldwide. These findings expand our understanding of the prevalence and genetic diversity of Eimeria and Entamoeba in alpacas.
