By Amir Johnson

Methicillin-Resistant Staphylococcus aureus, or MRSA for short, is a Gram-positive cocci-shaped (spherical) bacterium that measures approximately 1μm in diameter and forms clusters that are popularly described as being grape-like. [1] S. aureus is present on and within the bodies of many individuals asymptomatically, and as a result of this it often remains unnoticed. According to studies around 20% of people are persistent nasal carriers of S. aureus and around 30% are intermittent carriers, with the remaining 50% not carrying the bacterium. [1] Other than within the nose, S. aureus can be commonly seen present on the skin, skin glands, guts, and a variety of mucous membranes. This presence within the body is referred to as colonization, and it significantly increases the chances of acquiring an infection by providing a reservoir of the pathogen. [1] In most cases, the previously asymptomatic, commensal S. aureus that colonized the microbiome of individuals is responsible for their infection. [2]
