摘要
Accurate definition and usage of terminology are critical to effective communication in science. In a recently published article, the clarity and consistency of the terms pathogenicity and virulence as used in invertebrate pathology were called into question, and a revision of these terms was proposed. Our objective was to examine definitions of pathogenicity and virulence and their use in invertebrate pathology, and respond to this article. Although usage of the terms pathogenicity and virulence varies, we found considerable consistency in the published definitions of these terms in the invertebrate pathology literature throughout the history of the discipline, as well as among related disciplines such as medicine and microbiology. We did not find the established definitions to be lacking in clarity or utility. Therefore, we recommend that the definition and use of these terms adhere to precedence. Specifically, pathogenicity is the quality or state of being pathogenic, the potential ability to produce disease, whereas virulence is the disease producing power of an organism, the degree of pathogenicity within a group or species. Pathogenicity is a qualitative term, an "all-or-none" concept, whereas virulence is a term that quantifies pathogenicity. (C) 2004 Elsevier Inc. All rights reserved.
