Man constantly interacts with the world of microorganisms from birth to death. The majority cause no harm and some play a role in the normal functioning of the mouth, vagina and lower intestinal tract. However, many microorganisms have the potential to produce disease. This may result from inoculation of damaged tissues, tissue invasion, a variety of virulence factors or toxin production.
