鼠疫自然疫源地构成成分及其作用分析

摘要:鼠疫是由鼠疫耶尔森菌引起的一种发病急、传染性强、病死率高的自然疫源性疾病。鼠疫自然疫源地指在合适的地理景观条件下，由鼠疫耶尔森菌、宿主、媒介在长期的共同进化中相互适应而形成的特殊生态系统。研究鼠疫自然疫源地的构成成分及其作用，对了解鼠疫自然疫源地性质和结构，维持鼠疫生态系统平衡，有效预防和控制鼠疫疫情有着重要意义。

Analysis for the compositions of plague natural foci and their Roles

Abstract: Plague, a natural focus infection disease with acute onset, strong communication, and high mortality rate, is caused by Yersinia pestis. Plague natural foci refer to special ecological systems, which include Yersinia pestis, hosts, vectors, and appropriate geographical landscape. Studying the compositions of plague natural foci and their roles will be of great significance to know the properties and structures of plague natural foci, to maintain the balance of plague ecosystem, and to prevent and control plague occurrence effectively.
