So, microbes – especially bacteria and fungi – use antibiotics to kill other microbes. These other microbes can be bacteria, fungi or bigger organisms. Bacteria toxins which can be classified as either exotoxins or endotoxins. Exotoxins are generated and actively secreted; endotoxins remain part of the bacteria. Usually, an endotoxin is part of the bacterial outer membrane, and it is not released until the bacterium is killed by the immune system.
