Skin Flora Research Paper

Skin considers as the largest body organ. It protects us against the infection, at the same time it is the home to huge numbers of microorganisms. Our skin was sterile only once in our life when we were in the womb, they start colonization of a newborn baby's skin usually occurs during vaginal delivery through the birth canal after birth until death. such as bacteria, fungi and virus. Generally they are non-pathogenic, many are harmless and some are actually very helpful. The number of the microorganisms that found on the skin are more than anywhere else in the body after the gut. Most of them are bacteria. The total number of bacteria in an average human has been estimated about 1 trillion, most found in the superficial layers of the epidermis and the upper parts of the hair follicles. …show more content…
we have two type of normal microbial flora ( The first one Resident flora, it consists of relatively fixed type of microorganisms regularly found in a given area at a given age If disturbed, it promptly reestablishes itself and the second is Transient flora, it consists of nonpathogenic or potentially pathogenic microorganisms that inhabit the skin or mucous membranes for hours or days).There are some factors that influencing microbial growth on the skin includes: skin PH, moisture, temperature, oxygen, sun exposure, interacting with other microorganism and innate host defense. Microorganisms are found all over the skin surface, but the species vary anatomical site skin sites can be grouped into three types:1-Dry body sites: include the forearms, hands, legs and feet. They have the most diverse microbiota, due to high exposure to the external environment. 2-Moist body sites: Elbow creases, beneath the breasts, in-between the toes and the
