The skin is a very important protection against microbes. Some microbes are small enough to get in the pores of the skin. The skin is not a complete seal from the outer world.
There is more than a millions like billions or gazillions of microbes that lives on our skin!!!
Skin prevents microbes from entering your body...
Skin is the outer covering of the body that protects against microbes and germs.
Through microbes you breath in then the microbes settle and grow into fungus
Puss is made of small microbes found in the upper layers of your skin. These microbes cause various forms of skin cancer if not treated. Puss, which can usually found in acne, can be a sign of an early death related to cancerous skin cells.
Let us be correct and call these bacteria and/or virus or microbes. They each can be transmitted through direct contact, indirect contact or through the air. Direct contact includes touching with bare skin. Indirect contact is by leaving the microbes on a surface for someone else to pick up.
The skin has a number of defenses against microbes. The keratinized cells of the stratum corneum, the outer layer of the skin, provide a waterproof and physical barrier that protects the lower levels of the skin. These dead cells slough off, so that underlayers are not damaged. The sebaceous glands of the dermis produce sebum, which provides additional waterproofing. The skin also has an "acid mantle," a layer of chemical protection against microbes. Lastly, the skin has immune cells known as dendritic cells that identify and engulf bacteria, then move them to immune system cells that can react. The dendritic cells in the skin are known as Langerhans cells. Mast cells in the skin are white blood cells that release histamine to start an inflammatory reaction to fight infection. All of these structures and processes defend the skin and, by extension, the interior of the body against microbes.
Microbes are mostly transporter through the air. They can be aerosolized into bioaerosols and carried to and deposited into different environments.
through multiplying in your tissue
Antiseptic products, such as hand sanitizers or antibacterial ointments, are applied to the skin to reduce microbes and prevent infections. These products typically contain active ingredients like alcohol or antimicrobial agents that help kill or inhibit the growth of bacteria on the skin.
Through an opening, mouth, nose, eyes, ears, anus, urinary tract, or a cut in the skin.
Not all microbes are harmful. Some are quite helpful. As humans, we actually have microbes in our bodies and on our skin that work to keep us from getting certain diseases.
