Mechanism of Exotoxin | Pathogens & Diseases

An exotoxin is a toxin secreted by bacteria.[1] 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. Gram negative pathogens may secrete outer membrane vesicles containing lipopolysaccharide endotoxin and some virulence proteins in the bounding membrane along with some other toxins as intra-vesicular contents, thus adding a previously unforeseen dimension to the well-known eukaryote process of membrane vesicle trafficking, which is quite active at the host-pathogen interface.
This Video discusses about the following things :
1.Action mechanism of Exotoxins in detail.
2.Types of Exotoxins.
3.Diseases caused by Exotoxins
