真菌毒素是由丝状真菌如镰刀菌属、曲霉属和青霉属等所产生的有毒次生代谢物。其通过食品或饲料进入人或动物体内，会引起人或动物急性或慢性中毒，并导致机体的脏器(肝脏和肾脏)、组织(神经、皮肤)、生殖系统和生长性能等严重下降，甚至死亡。为全面了解国内外对真菌毒素的研究现状和前沿动态，基于Web of Science(WOS)核心合集数据库和中国知网(CNKI)数据库，以真菌毒素为主题，利用CiteSpace 6。2。R4可视化软件对近40多年与真菌毒素相关文献的发文量年度分布、核心作者、所属机构、国家间合作关系、文献来源、关键词和被引率等多方面进行文献计量分析。研究结果显示，WOS和CNKI两个数据库中分别共检索出文献19382篇和5320篇，发文量随时间的推移呈总体上升趋势。在国家间合作发文量来看，中国位列第2，发文量为2867篇，占总发文量的14。79％，表明中国在该领域的发文量较多。来自美国的第一作者Bennett Joshua Ward发表的题目为Mycotoxins的论文被引用次数最高，为2 468次，有较大的影响力。从高频关键词可看出目前的研究热点主要集中在真毒毒素、霉菌毒素、氧化应激和生物脱毒等方面。
Bibliometric analysis of mycotoxin research based on Web of Science and the China National Knowledge Infrastructure
Mycotoxins are toxic secondary metabolites produced by filamentous fungi,such as Fusarium,Aspergillus,and Penicillium.People or animals can be exposed to this toxin through food or feed,resulting in acute or chronic poisoning and damage to the liver,kidney,nervous tissue,reproductive system,and skin and causing a serious decline in growth performance or even death.To understand the current research status and frontier trends of mycotoxins locally and abroad,the Web of Science(WOS)core collection database and the China National Knowledge Infrastructure(CNKI)database were searched.The visualization software CiteSpace 6.2.R4 was used to conduct bibliometric analysis of the annual distribution of publication volume,core authors,affiliated institutions,cooperation relationships between countries,literature sources,keywords,and citation rates of literature related to mycotoxins over the past 40 years.A total of 19382 articles and 5 320 articles were retrieved from the WOS and CNKI databases,respectively,with an overall upward trend in the number of publications over time.China ranked second in terms of the number of collaborative publications between countries,indicating that China has a large number of publications in this field,with a total of 2 867 articles,accounting for 14.79％of the total number.The paper entitled Mycotoxins published by Bennett Joshua Ward as the first author,from the United States,had the highest citation count of 2468 and thus,had great influence on the field.Based on the high-frequency keywords,it can be seen that the current research hotspots mainly focused on mycotoxins,oxidative stress,deoxynivalenol,fusarium head blight,fumonisin,and lactic acid bacteria.
