WebEndotoxin is a lipopolysaccharide component of the Gram-negative bacteria cell and is released during active cellular growth and after cell lysis. While it is not an infectious particle, endotoxin is biologically active material derived from bacteria that can affect many human organ systems and disrupt humoral and cellular host mediation systems. WebThe release of LPS from bacteria in our gut starts with an inflammatory meal. An inflammatory meal leads to a chain of events that creates endotoxins and allows their release past the gut barrier.
