可以感染多个寄主物种的病原体与仅限于单一寄主物种的病原体具有不同的动态。本文探讨了感染多种寄主的病原菌的建立条件和长期种群动态行为。本文试图解决这一领域的三个主要问题：第一，在什么条件下，宿主物种多样性的增加会缓冲传染病暴发，在什么条件下，宿主多样性会放大疾病暴发？第二，在什么条件下，通过集中控制只针对一种宿主物种来控制传染病病原体是可能的？第三，寄主物种多样性在维持病原体持久性方面发挥了什么作用？这些问题的答案为生物多样性在缓冲人类和其他物种抵御新出现的病原体方面所起的作用提供了一些重要的一般性见解。
Pathogens that can infect multiple host species will have different dynamics than pathogens that are restricted to a single species of host. This article examines the conditions for establishment and long-term population dynamic behavior of pathogens that infect multiple species of hosts. The article attempts to address three major questions in this area: First, under which conditions will increases in the diversity of host species buffer infectious disease outbreaks, and under which conditions will host diversity amplify disease outbreaks? Second, under what conditions is it possible to control an infectious agent by focusing control against only one host species? Third, what role does host species diversity play in maintaining pathogen persistence? The answers to these questions supply some important general insights into the role that biodiversity plays in buffering humans and other species against new and emerging pathogens.
