Role of Microbes in Human Health

Abstract

A variety of microbes exists throughout the human body and have fundamental role in human health. Studies have revealed that human microbiome of every healthy individual differs remarkably in the matter of different varieties of microbes. In the body, these microbes are present in different parts such as skin, nasal cavity, oral cavity, gut and vagina and therefore stay in different habitats. Some microbes that colonize humans are commensal, whereas others have a mutualistic relationship with the host. These interactions are important for human to grow and stay healthy. This mini-review describes about the microbes present in different human habitats and their roles in keeping the person healthy.
