  2. Methicillin-resistant Staphylococcus aureus - Wikipedia

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

    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.

  3. SCCmec - Wikipedia

    en.wikipedia.org/wiki/SCCmec

    SCCmec, or staphylococcal cassette chromosome mec, is a mobile genetic element of Staphylococcus bacterial species. 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]

  4. List of antibiotic-resistant bacteria - Wikipedia

    The evolution of bacteria on a "Mega-Plate" petri dish A list of antibiotic resistant bacteria is provided below. These bacteria have shown antibiotic resistance (or antimicrobial resistance). Gram positive Clostridioides difficile Clostridioides difficile is a nosocomial pathogen that causes diarrheal disease worldwide. Diarrhea caused by C. difficile can be life-threatening. Infections are ...

  6. Staphylococcus aureus - Wikipedia

    en.wikipedia.org/wiki/Staphylococcus_aureus

    The β-lactamase-resistant penicillins (methicillin, oxacillin, cloxacillin, and flucloxacillin) were developed to treat penicillin-resistant S. aureus, and are still used as first-line treatment. Methicillin was the first antibiotic in this class to be used (it was introduced in 1959), but only two years later, the first case of methicillin ...

  7. Staphylococcus haemolyticus - Wikipedia

    en.wikipedia.org/wiki/Staphylococcus_haemolyticus

    S. haemolyticus has the highest level of antibiotic resistance among the CoNS. [15] Various strains are resistant to one or more of these antibiotics: penicillins, cephalosporins, macrolides, quinolones, tetracyclines, aminoglycosides, glycopeptides, and fosfomycin (see table in Genome structure), [5] [10] [22] [23] and multidrug resistance is ...

  8. Staphylococcus hominis - Wikipedia

    en.wikipedia.org/wiki/Staphylococcus_hominis

    The combined resistance to novobiocin and oxacillin is hypothesized to have originated from a simultaneous introduction of genes controlling the resistance to the two. These genes were believed to have been acquired originally through heterologous DNA from a methicillin-resistant strain of one of the novobiocin-resistant species belonging to ...

  9. Staphylococcus schleiferi - Wikipedia

    en.wikipedia.org/wiki/Staphylococcus_schleiferi

    The mecA gene is carried by a mobile genetic element called the staphylococcal cassette chromosome mec (SCCmec) which is thought to promote spread between different species. [58] The presence of the mecA gene, expression of PBP2a, and methicillin resistance has been reported in S. schleiferi isolates. [13]
