  2. Methicillin-resistant Staphylococcus aureus - Wikipedia

    en.wikipedia.org/wiki/Methicillin-resistant...

    The mecA gene, which confers resistance to a number of antibiotics, is always present in MRSA and usually absent in MSSA; however, in some instances, the mecA gene is present in MSSA but is not expressed. Polymerase chain reaction (PCR) testing is the most precise method for identifying MRSA strains. Specialized culture media have been ...

  4. Staphylococcus aureus - Wikipedia

    en.wikipedia.org/wiki/Staphylococcus_aureus

    Resistance is conferred by the mecA gene, which codes for an altered penicillin-binding protein (PBP2a or PBP2') that has a lower affinity for binding β-lactams (penicillins, cephalosporins, and carbapenems). This allows for resistance to all β-lactam antibiotics, and obviates their clinical use during MRSA infections.

  5. SCCmec - Wikipedia

    en.wikipedia.org/wiki/SCCmec

    This genetic sequence includes the mecA gene coding for resistance to the antibiotic methicillin and is the only known way for Staphylococcus strains to spread the gene in the wild by horizontal gene transfer. [1] SCCmec is a 21 to 60 kb long genetic element that confers broad-spectrum β-lactam resistance to MRSA. [2]

  6. Methicillin - Wikipedia

    en.wikipedia.org/wiki/Methicillin

    Resistance to methicillin is conferred by activation of a new bacterial penicillin binding protein (PBP) mecA gene. This encodes protein PBP2a. This encodes protein PBP2a. PBP2a works in a similar manner to other PBPs, but it binds β-lactams with very low affinity, meaning they do not compete efficiently with the natural substrate of the ...

  8. Penicillin-binding proteins - Wikipedia

    en.wikipedia.org/wiki/Penicillin-binding_proteins

    Presence of the protein penicillin binding protein 2A (PBP2A) is responsible for the antibiotic resistance seen in methicillin-resistant Staphylococcus aureus (MRSA). [ 12 ] The β-lactam ring is a structure common to all β-lactam antibiotics.
