An exotoxin is a toxin secreted by bacteria. An exotoxin can cause damage to the host by destroying cells or disrupting normal cellular metabolism. They are highly potent and can cause major damage to the host. Exotoxins may be secreted, or, similar to endotoxins, may be released during lysis of the cell. Exotoxin; Enterotoxin; Bacterial Exotoxin. Exotoxins are proteins that are produced and released extracellularly by gram-positive and gram-negative bacteria. Exotoxins are soluble, heat-labile proteins, which are mainly produced in the surrounding environment where bacteria grow.

Although different techniques have been em-ployed to prepare and isolate these agents, the weight of present evidence strongly suggests that they contain the same diarrheagenic entero-toxin andthat this enterotoxin is responsible for 24. The main difference between endotoxin, Enterotoxin, and exotoxin is that endotoxin s a lipopolysaccharide found in the outer membrane of the Gram-negative bacteria, exotoxin is a protein secreted by gram-positive bacteria whereas Enterotoxin is a type of exotoxin in the intestines.

Enterotoxins are produced in or released into intestines. Certain bacterial species are capable of producing enterotoxins. Enterotoxins belong to the category of exotoxin. Secondly, endotoxins are heat stable, weakly immunogenic while exotoxins are heat labile, highly antigenic. Endotoxins are produced by Gram-negative bacteria, while exotoxins are generally produced by Gram-positive or some by Gram-negative bacteria.
