Colorized scanning electron micrograph of a human neutrophil ingesting MRSA. Methicillin-resistant Staphylococcus aureus (MRSA) is a group of gram-positive bacteria that are genetically distinct from other strains of Staphylococcus aureus. MRSA is responsible for several difficult-to-treat infections in humans.
Daptomycin is a cyclic lipopeptide antibiotic primarily used for treating Gram-positive bacterial infections, including those caused by Staphylococcus aureus. It was first approved in 2003 and is especially effective against resistant strains like methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Staphylococcus aureus ...
Methicillin-resistant Staphylococcus aureus (MRSA) – MRSA is one of the most common antibiotic-resistant strains of staph bacteria. It is more difficult to treat than other staph infections. MRSA causes rashes, boils, sores, and other abscesses.
The anterior nares can act as a colonizing point from which the infection can spread. [2] This can be particularly troublesome if the strain is an antibiotic-resistant (commonly MRSA or ORSA) strain. MRSA (first discovered in the UK in 1961) has become particularly widespread in hospitals and is commonly considered a super bug.
Mupirocin, sold under the brand name Bactroban among others, is a topical antibiotic useful against superficial skin infections such as impetigo or folliculitis. [5] [6] [7] It may also be used to get rid of methicillin-resistant S. aureus (MRSA) when present in the nose without symptoms. [6]
Staphylococcus intermedius is a Gram-positive, catalase positive member of the bacterial genus Staphylococcus consisting of clustered cocci. Strains of this species were originally isolated from the anterior nares of pigeons, dogs, cats, mink, and horses. Many of the isolated strains show coagulase activity. [2]
ST8:USA300 is a strain of community-associated methicillin-resistant Staphylococcus aureus that has emerged as a particularly antibiotic resistant epidemic that is responsible for rapidly progressive, fatal diseases including necrotizing pneumonia, severe sepsis and necrotizing fasciitis. [1]
