Cannot be used on human body or on live objects. Usually used on inanimate objects: antiseptics similar to disinfection, but usually milder chemicals. They caused diseases such as cjd or mad-cow disease.

Two groups or organisms produce endospores: bacillus and clostrydium. Killing endospores is very difficult, it takes more energy and a higher temperature: mycobacterium, staphylococcus and pseudomonas pseudomonas is an organism that causes opportunistic infection. Actions of various physical and chemical agents upon the cell: one of the best targets is the cell wall of bacteria.
