Objective: To understand the current research focus and trends in the field of snail intestinal flora.
Methods: The literature focusing on snail intestinal flora and published from 1998 to 2017 were retrieved from the core database of Web of Science. The quantitative analysis of literature was then conducted by using CiteSpace software based on the bibliometricsmethod.The research trends were then summarized systematically, and the potential research fronts and focuses were explored.
Results: Totally 139 articles were identified in the field of snail intestinal flora. The top three countries with highest publications included the United States of American, Brazil, and South Korea; while the top three institutions were Kyung Hee University, Osvaldo Cruz Foundation, and Oxford University. Five terms were identified as the key words in this field, including diversity, cellulose, Achatina fulica, lignocelluloses, and species nova. Meanwhile, 5 critical papers with the citation frequency over 15 were recognized, and 5 study clusters were formed including the application, diversity, and function of intestinal flora, difference of snail source and flora, and newly discovered bacteria in the snail intestine.
Conclusions: The current research focuses on intestinal flora of snails include the diversity, function and application of intestinal flora.
［摘要］ 目的了解当前螺类肠道菌群研究领域现状及热点问题。方法检索1998-2017年Web of Science核心数据 库中螺类肠道菌群研究领域相关论文, 采用文献计量学方法, 通过CiteSpace软件进行定量分析。结果共检索到螺类 肠道菌群领域文献139篇, 发文量居前3位的国家为美国、巴西、韩国, 发文较多的研究机构包括庆熙大学、奥斯瓦尔多· 克鲁兹基金会、牛津大学等。螺类肠道菌群研究领域关键主题词包括多样性、纤维素酶、木质纤维素、褐云玛瑙螺、新物 种, 被引频次＞15的文献有5篇。主题词聚类分析共形成了肠道菌群的应用、肠道菌群多样性、肠道菌群功能、环境与螺 类肠道菌群差异及螺类肠道新发现菌种等5个聚类。结论肠道菌群多样性及肠道菌群的功能和应用研究是当前螺类 肠道菌群研究领域的热点问题。.
