Focal infection in perspective.
In this article some of the theoretical possibilities arising as a result of focal infection are discussed. Rheumatic fever is discussed as an example of a disease in which a number of possible mechanisms may act to produce tissue damage at a target area. The mechanisms examined are direct dissemination of organisms from the focus to the target area, the induction of L-phase bacteria, and toxic damage to target tissue. Host-mediated tissue damage by hypersensitivity or auto-immune mechanisms is considered as well.
