exotoxiny
Exotoxins are protein toxins secreted by living bacteria. They are released into the surrounding environment during bacterial growth and multiplication. Unlike endotoxins, which are part of the bacterial cell wall, exotoxins are actively produced and actively released. They are typically potent and can cause severe damage to host cells and tissues even at very low concentrations.
Exotoxins are often heat-labile, meaning they can be inactivated by heat. They are usually encoded by genes
The body's immune system can produce antibodies called antitoxins that neutralize exotoxins. This principle is used
