  2. Skin flora - Wikipedia

    en.wikipedia.org/wiki/Skin_flora

    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 ...

  3. Bacterial adhesin - Wikipedia

    en.wikipedia.org/wiki/Bacterial_adhesin

    In gram-positive bacteria, a protein or polysaccharide surface layer serves as the specific adhesin. To effectively achieve adherence to host surfaces, many bacteria produce multiple adherence factors called adhesins. Bacterial adhesins provide species and tissue tropism. Adhesins are expressed by both pathogenic bacteria and saprophytic bacteria.

  4. Staphylococcus pseudintermedius - Wikipedia

    en.wikipedia.org/wiki/Staphylococcus...

    The previously mentioned protein A, as well as clumping factor, are surface proteins that allow the bacteria to bind to host cells. [20] [7] S. pseudintermedius has been found to produce biofilms, an extracellular matrix of protein, DNA, and polysaccharide, which aids the bacteria in avoiding the host immune system and resisting drugs. [6]

  5. Staphylococcus aureus - Wikipedia

    The other proteins are EsaA, EssB, EssA, that are membrane proteins that function alongside EssC to mediate protein secretion. The exact mechanism of how substrates reach the cell surface is unknown, as is the interaction of the three membrane proteins with each other and EssC. [67] T7 dependent effector proteins

  6. Human microbiome - Wikipedia

    en.wikipedia.org/wiki/Human_microbiome

    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 ...

  7. Bacterial cell structure - Wikipedia

    en.wikipedia.org/wiki/Bacterial_cell_structure

    An S-layer (surface layer) is a cell surface protein layer found in many different bacteria and in some archaea, where it serves as the cell wall. All S-layers are made up of a two-dimensional array of proteins and have a crystalline appearance, the symmetry of which differs between species.

  8. Human skin - Wikipedia

    en.wikipedia.org/wiki/Human_skin

    In terms of surface area, the skin is the second largest organ in the human body (the inside of the small intestine is 15 to 20 times larger). For the average adult human, the skin has a surface area of 1.5–2.0 square metres (15–20 sq ft).

  9. Dermcidin - Wikipedia

    en.wikipedia.org/wiki/Dermcidin

    Dermcidin is a protein with 110 amino acids that in humans is encoded by the DCD gene. [3] [4] The full-length protein produces derived peptides as proteolysis-inducing factor (PIF) and other anti-microbial peptides, [4] secreted by human eccrine sweat glands onto the skin as a part of the innate host defense of the immune system.
