Skin flora, also called skin microbiota, refers to microbiota (communities of microorganisms) that reside on the skin, typically human skin. Many of them are bacteria of which there are around 1,000 species upon human skin from nineteen phyla. [1] [2] Most are found in the superficial layers of the epidermis and the upper parts of hair follicles.
It is part of the skin flora of humans, [3] and its largest populations are usually found at the axillae, perineum, and inguinal areas. [4] S. haemolyticus also colonizes primates and domestic animals. [4] It is a well-known opportunistic pathogen, and is the second-most frequently isolated CoNS (S. epidermidis is the first). [5]
Cutibacterium acnes bacteria predominantly live deep within follicles and pores, although they are also found on the surface of healthy skin. [3] In these follicles, C. acnes bacteria use sebum, cellular debris and metabolic byproducts from the surrounding skin tissue as their primary sources of energy and nutrients.
Cellulitis can be caused by normal skin flora or by contagious contact, and usually occurs through open skin, cuts, blisters, cracks in the skin, insect bites, animal bites, burns, surgical wounds, intravenous drug injection, or sites of intravenous catheter insertion. In most cases it is the skin on the face or lower legs that is affected ...
Graphic depicting the human skin microbiota, with relative prevalences of various classes of bacteria. The human microbiome is the aggregate of all microbiota that reside on or within human tissues and biofluids along with the corresponding anatomical sites in which they reside, [1] [2] including the gastrointestinal tract, skin, mammary glands, seminal fluid, uterus, ovarian follicles, lung ...
The blistering rash on 7-month-old Sobhia’s skin is the result of bacteria from polluted water, doctors told her mother. The infant, who was born a few months after the start of the Israel-Hamas ...
It is found in soil, water, skin flora, and most human-made environments throughout the world. As a facultative anaerobe, P. aeruginosa thrives in diverse habitats. It uses a wide range of organic material for food; in animals, its versatility enables the organism to infect damaged tissues or those with reduced immunity.
The skin microbiome is a go-between, interacting with both our body’s internal world and the external world. The results of these interactions impact our individual health in ways we are only ...
