What are the hardest microbiological structures to destroy?

Endospores are considered the most resistant structure of microbes. They are resistant to most agents that would normally kill the vegetative cells they formed from. Mycobacterial infections are notoriously difficult to treat. Protozoa cysts are quite hard to eliminate too.

What is the difference between a disinfectant and an antiseptic?

Antiseptics and disinfectants are both widely used to control infections. They kill microorganisms such as bacteria, viruses, and fungi using chemicals called biocides. Disinfectants are used to kill germs on nonliving surfaces. Antiseptics kill microorganisms on your skin.

When only the vegetative pathogens are destroyed it is called?

Term. Disinfection. Definition. Destruction or removal of vegetative pathogens but not bacterial endospores.

Is the complete destruction of all forms of microbial life?

Are all microorganisms on or in your skin are harmful?

The majority of microorganisms on our skin are commensals, as they infrequently cause ill health. However, in some circumstances commensal microbes such as S. epidermidis have beneficial or pathogenic roles. Commensal microorganisms can prevent colonisation of pathogenic microorganisms such as S.
