Examples of A-B toxins include: Diphtheria exotoxin, produced by Corynebacterium diphtheriae (inf). This toxin interferes with host cell protein synthesis by catalyzing the ADP-ribosylation of host cell elongation factor 2 (EF-2), necessary in order for tRNA to insert new amino acids into the growing protein chain. This results in cell death.

The toxin can be informed of endotoxin, exotoxin, and enterotoxin. 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.

• Streptococcal pyrogenic exotoxin (Spe) (toxic. By contrast, very small concentrations of exotoxins can be lethal. For example, botulinum toxin, which causes botulism, has an LD50 of 0.000001 mg/kg Samples were collected hourly. One portion of the sample was used to determine bacterial density and the other was quickly frozen and kept for β-lactamase establish themselves in the host. One example is leukocidins, a group of.

Exotoxin. 1. Endotoxins are Lipopolysaccharides (LPS) Exotoxins are proteins. 2. Endotoxins are not secreted by the bacterium, they remain attached to the bacterial cell. Exotoxins are actively secreted into the external medium by the bacterial cells. 3. Cell lysis is required for the release of endotoxins.
