Differences between exotoxins and endotoxins |
|
Definition
Exotoxin: *secreted by living bacterial cell into infected tissues *proteins with a strong specificity for a target cell and extremely powerful, sometimes deadly Endotoxin: *released after the cell is damaged or lysed. *lipopolysaccharide (LPS) which are part of the outer membrane of gram negative cell wall released from the cells walls of dead cells |
