历史上和目前对微生物致病机理和毒力的大多数观点都被混乱和不准确的术语和定义所困扰,这些术语和定义需要修订和例外,以适应关于微生物和传染病的新的基础科学和临床信息。这些观点本身也无法解释某些微生物在某些宿主中致病的能力,而不是其他宿主,因为它们植根于单一的、要么是以微生物为中心的观点,要么是以宿主为中心的观点。损伤-反应框架是微生物致病机理的综合理论,它提出微生物的致病机理反映了宿主和微生物之间相互作用的结果,每个个体都对结果的性质做出了贡献,而结果的性质又取决于宿主-微生物相互作用造成的宿主损害的量。这一观点能够容纳新的信息,并解释为什么感染同一种微生物在不同的宿主上会有不同的结果。本章描述了《损害-反应框架》中提出的感染的起源、概念基础和后果。
Historical and most currently held views of microbial pathogenesis and virulence are plagued by confusing and imprecise terminology and definitions that require revision and exceptions to accommodate new basic science and clinical information about microbes and infectious diseases. These views are also inherently unable to account for the ability of some microbes to cause disease in certain, but not other hosts, because they are grounded in singular, either microbe-or host-centric views. The damage-response framework is an integrated theory of microbial pathogenesis that puts forth the view that microbial pathogenesis reflects the outcome of an interaction between a host and a microbe, with each entiry contributing to the nature of the outcome, which in turn depends on the amount of host damage that results from the host-microbe interaction. This view is able to accommodate new information and explain why infection with the same microbe can have different outcomes in different hosts. This chapter describes the origins and conceptual underpinnings of and the outcomes of infection put forth in, the damage-response framework.
