Bacterial protein toxins. Exotoxins are usually secreted by living bacteria during exponential growth.

Bacterial protein toxins. The production of the toxin is generally specific to a particular bacterial species that produces the disease associated with the toxin (. only Clostridium tetani produces tetanus toxin; only Corynebacterium diphtheriae produces the diphtheria toxin). Usually, virulent strains of the bacterium produce the toxin while nonvirulent strains do not, and the toxin is the major determinant of virulence (. tetanus and diphtheria).

Bacterial toxins are involved in the pathogenesis of many bacteria, some of which are responsible for severe diseases in human and animals, but can also be used as tools in cell biology to dissect cellular processes or used as therapeutic agents. Novel recombinant toxins are already proposed in the treatment of some diseases, as well as new vaccines. Alternatively, certain toxins are also considered as biological weapons or bioterrorism threats

Microbial toxins are toxins produced by micro-organisms, including bacteria and fungi. Microbial toxins promote infection and disease by directly damaging host tissues and by disabling the immune system.

Microbial toxins are toxins produced by micro-organisms, including bacteria and fungi. Some bacterial toxins, such as Botulinum neurotoxins, are the most potent natural toxins known.

Classes of bacterial protein toxins. The first toxin to be understood at the molecular level was one from Clostrid-ium perfringens, a bacterium notorious for causing wound infections such as gas gangrene. This toxin is a phospholipase that attacks membranes of cells and, thus, it defined one of the three main categories of toxins, . those that attack membranes (MacFarlane and Knight, 1941).

Bacterial toxins are proteins capable of achieving multiple remarkable tasks. They function as autonomous molecular devices, targeting specific cells in an organism, punching holes in their membranes, or modifying intracellular components. Intoxication processes involve highly specialized steps of great complexity. Such toxins are seen in competition between multicellular eukaryotes (.

BACTERIAL PROTEIN TOXINS Exotoxins are usually secreted by living bacteria during exponential growth.

Bacterial protein toxins play an important role in infectious diseases. Several are highly potent human poisons, such as botulinum, tetanus, Shiga, and diphtheria toxins. These toxins are multi-functional proteins that are self-programmed to reach their target organs and/or enter cells. Another set of toxins is called effector, which is directly delivered into the cell by type III/IV mechanisms. To exert their potency, many of them interact specifically with key components of the cell.
