升金湖和菜子湖越冬小白额雁肠道病毒组成及结构特征研究

Gut viral composition and structure of wintering Anser erythropus in Shengjin and Caizi lakes

鸟类是人禽共患病的宿主及传播媒介,候鸟参与传播的病毒性疾病已成为研究热点。本研究对20份采集自安徽省升金湖和菜子湖的越冬小白额雁(Anser erythropus)的粪便样品(各10份)进行了分析,Alpha多样性和PCoA分析结果表明两个湖泊越冬小白额雁的肠道病毒群落均存在显著差异性。两个湖泊越冬小白额雁肠道病毒组在门的水平主要有Uroviricota,Nucleocytoviricota,Preplasmiviricota,Artverviricota,Pisuviricota,Hofneiviricota,Lenarviricota,Cressdnaviricota,Kitrinoviricota和Peploviricot。LEfSe分析结果表明,升金湖越冬小白额雁肠道中Uroviricota和Preplasmiviricota相对丰度较高,而菜子湖越冬小白额雁肠道中的Cressdnaviricota和Artverviricota相对丰度较高。本研究初步揭示了升金湖和菜子湖越冬小白额雁肠道病毒的组成及结构特征,为潜在的人禽共患病病原体的公共卫生风险防控提供基础数据,具有重要的流行病学和公共卫生意义。

Birds are the hosts and vectors of many zoonosis diseases,the transmission route and rule of disease between birds and human have become one of the most prevalent topics.In this study,20 fecal samples(10 in each)of wintering Anser erythropus from Shengjin and Caizi Lakes in Anhui Province were analyzed.It showed that the alpha diversity and PCoA diversity differed significantly between the Caizi Lake and Shengjin Lake samples.The Shengjin Lake and Caizi Lake samples contained Uroviricota,Nucleocytoviricota,Preplasmiviricota,Artverviricota.Pisuviricoto,Hofneiviricota,Lenarviricota,Cressdnaviricota,Kitrinoviricota and Peploviricota.The LEfSe analysis results indicated that Uroviricoto and Preplasmiviricota were significantly more abundant in Anser erythropus from Shengjin Lake,whereas Cressdnoviricota and Artverviricota were significantly more abundant in the geese from Caizi Lake.This study preliminorily revealed the composition and structural characteristics of gut viral communities of Anser erythropus wintering in Shengjin and Caizi Lakes,and provided basic data for public health risk prevention and control of potential pathogens for zoonosis,which has important epidemiological and public health significance.
