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. It caused more than 100,000 deaths worldwide attributable to antimicrobial resistance in 2019.
But, each type of skin infection caused by staph bacteria is different. A few common skin infections caused by staph bacteria are: Boils – Boils are the most common type of staph infection, they are pockets of white pus that start where a hair follicle or oil gland is. The boil is tender and red where the infection is located on the skin.
Oral antimicrobial treatment for active infection is commonly done with the use of mupirocin, linezolid, quinupristin, rifampicin or vancomyocin are possible treatments. [42] [43] Hand washing, sterilizing equipment and hygiene practices should be implemented to decrease the spread of Staphylococcus infections. [20] [43]
Staphylococcus aureus is a significant cause of chronic biofilm infections on medical implants, and the repressor of toxins is part of the infection pathway. [30] Staphylococcus aureus can lie dormant in the body for years undetected. Once symptoms begin to show, the host is contagious for another two weeks, and the overall illness lasts a few ...
At one time, methicillin was used to treat infections caused by certain gram-positive bacteria including Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, and Streptococcus pneumoniae. Methicillin is only effective against Staphylococcus aureus 50% of the time.
[9] [23] An example is the use of PCR to detect the mecA gene for beta-lactam resistant Staphylococcus aureus. [9] Other examples include assays for testing vancomycin resistance genes vanA and vanB in Enterococcus species, and antibiotic resistance in Pseudomonas aeruginosa, Klebsiella pneumoniae and Escherichia coli.

S. aureus can cause a range of illnesses from minor skin infections to Staphylococcus aureus food poisoning enteritis. Since humans are the primary source, cross-contamination is the most common way the microorganism is introduced into foods. Foods at high risks are those prepared in large quantities.
