Definitions

• the skin is the human body's largest organ, colonized by a diverse range of microorganisms, the majority of which are harmless or even beneficial to their host. These microorganisms often provide vital functions that the human genome has not yet evolved to perform. In this way, the skin constantly regulates a balance between host-human and microorganism. Disruptions in this delicate balance, on either side, can result in serious skin disorders or infections.
• Pathogens on the skin are known to cause illness and may be easily transmitted from one person to another. Some pathogens stick strongly to skin. Typically, when pathogens stick to skin, they are more difficult to remove or kill using traditional approaches to skin cleaning and disinfection such as washing with soap or using a waterless sanitizer. Pathogens that are stuck to skin are more dangerous because they remain on the skin longer. The longer the pathogen is on the skin, the more the chance that they will either cause infections on the person with them or be shared with other people.
• Probiotics are being used to control microbes on skin in new ways that do not require the use of antimicrobials.
• Probiotics are live or inactivated microorganisms that, when either present as part of the normal microbiota or when administered in adequate amounts, confer a health or cosmetic benefit on the host. Benefits from probiotics can be from the microbial components directly or can come from the byproducts of bacterial growth.
• Antimicrobial peptides comprise a wide range of natural and synthetic peptides that are made of oligopeptides containing a varying number of amino acids. AMPs may be produced by a host, or by the skin microbiota itself. AMPs are essential components of host defense against infections present in all domains of life. AMPs are produced by all complex organisms and have diverse and intricate antimicrobial activities. As a whole, these peptides demonstrate a broad range of antiviral and antibacterial activities through an array of modes of action. AMPs have been found to kill Gram-negative and Gram-positive bacteria, certain viruses, parasites and fungi.
