This book is divided into six chapters that cover a wide range of endotoxin biology topics. The first chapter provides a general overview of endotoxins, as well as a timeline of their use and discovery. In Chapter Two, we'll look at how to extract and characterize these compounds. In Chapter Three, the genetics and biochemical pathways involved in endotoxin biosynthesis are discussed in depth. In Chapter Four, endotoxin virulence is discussed, as well as the mechanisms of host-pathogen interactions. In Chapter Five, the use of endotoxins as vaccine adjuvants is discussed as a futuristic way to improve vaccine efficacy. At the end, Chapter Six discusses potential areas of endotoxin exposure in the environment, as well as measures to combat the ecological threat.
