Mercer, or methicillin-resistant Staphylococcus aureus (MRSA), is caused by a strain of the Staphylococcus aureus bacteria that has developed resistance to methicillin and other antibiotics. This resistance often arises from the overuse and misuse of antibiotics, leading to the selection of resistant strains. MRSA infections can occur in various settings, including hospitals and community environments, and are typically transmitted through direct skin contact or contaminated surfaces. Factors such as weakened immune systems, crowded living conditions, and poor hygiene can increase the risk of infection.
