Mechanism of Pathogenicity 2. Pathogens & Disease Pathogens are defined as microbes capable of causing host damage. When host damage reaches a certain threshold, it can manifest itself as a disease. The evolution of an infectious disease in an individual involves complex interactions between the pathogen and the host. 2021-04-08 · A portion of the lipopolysaccharide, called the lipid A, is a cell-associated toxin, or an endotoxin.

Immunogenicity Endotoxin vs. Exotoxin Endotoxins are the lipopolysaccharides that are an integral part of the cell membrane of the gram-negative bacteria and become toxin in some conditions. Exotoxins are heat labile, proteinaceous substances or toxoids that are liberated by mostly gram-positive bacteria but sometimes also by gram-negative bacteria into its Endotoxins and exotoxins are very much alike in the sense that they both cause damage to the cells and to the host as a whole. However, they differ in many ways. In this article, we are going to discuss in details the differences between endotoxins and exotoxins.
