The term skin flora also commonly referred to as skin microbiota refers to the microorganisms which reside on the skin, typically human skin. Many of them are bacteria of which there are around 1, species upon human skin from nineteen phyla. Skin flora is usually non-pathogenic, and either commensal are not harmful to their host or mutualistic offer a benefit.
Microbes are everywhere. They populate the air, the water, the soil, and have even evolved intimate relationships with plants and animals. Without microbes, life on earth would cease. This is due mainly to the essential roles microbes play in the systems that support life on earth, such as nutrient cycling and photosynthesis. Further, the physiology, nutrition and protection of plants and animals including humans is dependent on various relationships with microbes.

The microorganisms that live inside and on humans now referred to as the normal microbiota are estimated to outnumber human somatic and germ cells by a factor of The genomes of these microbial symbionts are collectively defined as the microbiome. Shifts in the normal microbiota or stimulation of inflammation by these commensals may cause diseases such as bacterial vaginosis, periodontitis, and inflammatory bowel disease.

Healthy people live in harmony with most of the microorganisms that establish themselves on or in colonize nonsterile parts of the body, such as the skin, nose, mouth, throat, large intestine, and vagina. The microorganisms that usually occupy a particular body site are called the resident flora. Cells of the resident flora outnumber a person's own cells 10 to 1. Microorganisms that colonize people for hours to weeks but do not establish themselves permanently are called transient flora. The resident flora at each site includes several different types of microorganisms.
In this article we will discuss about the normal microflora of different parts of human body. An average adult human is covered with approximately 2 m 2 of skin. It has been estimated that this surface area supports about 10 12 bacteria. The skin Fig.
