Abstract

The vaginal microbiota helps to prevent urogenital diseases and maintain health, through the production of lactic acid. The human body houses microorganisms that inhabit the surfaces and cavities exposed to the external environment. Each part of the body includes groups of microbial species that exist in a symbiotic relationship with the host. The types of organism’s present are dependent on the present environmental conditions and host factors, but they vary from site to site and between individuals over time.
