What is the definition of a non-pathogen?

The definition of a non-pathogen is indeed a microbe that usually does not cause infections. Non-pathogens are generally harmless microorganisms that coexist in the environment and within the human body. Many non-pathogenic microbes play crucial roles in various biological processes, such as aiding digestion and supporting the immune system.

Unlike pathogens, which are organisms capable of causing disease and infections, non-pathogens do not typically lead to harmful effects in healthy individuals. Understanding the difference between pathogens and non-pathogens is essential in infection control and hygiene practices, as this knowledge helps healthcare providers prevent the spread of infections while recognizing the beneficial aspects of certain microbes.
