  2. Methicillin-resistant Staphylococcus aureus - Wikipedia

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

    Diagram depicting antibiotic resistance through alteration of the antibiotic's target site, modeled after MRSA's resistance to penicillin. Beta-lactam antibiotics permanently inactivate PBP enzymes, which are essential for cell wall synthesis and thus for bacterial life, by permanently binding to their active sites. Some forms of MRSA, however ...

    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 ...

  5. Staphylococcus aureus - Wikipedia

    en.wikipedia.org/wiki/Staphylococcus_aureus

    Methicillin-resistant Staphylococcus aureus (MRSA, often pronounced / ˈ m ɜːr s ə / or / ɛ m ɑːr ɛ s eɪ /), is one of a number of greatly feared strains of S. aureus which have become resistant to most β-lactam antibiotics. For this reason, vancomycin, a glycopeptide antibiotic, is commonly used to combat MRSA. Vancomycin inhibits the ...

    en.wikipedia.org/wiki/Drug_of_last_resort

    One of the most commonly known examples of both antimicrobial resistance and the relationship to the classification of a drug of last resort is the emergence of Staphylococcus aureus (MRSA) (sometimes also referred to as multiple-drug resistant S. aureus due to resistance to non-penicillin antibiotics that some strains of S. aureus have shown ...

  7. MRSA ST398 - Wikipedia

    en.wikipedia.org/wiki/MRSA_ST398

    And Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium that is resistant to many antibiotics. The abbreviation "ST" in MRSA ST398 refers to the sequence type of the bacterium. MRSA ST398 is a clonal complex 398 (CC398). This means that the strain had emerged in a human clinic, without any obvious or understandable causes.

  8. Methicillin - Wikipedia

    en.wikipedia.org/wiki/Methicillin

    Methicillin and other β-lactam antibiotics are structural analogs of D-alanyl-alanine, and the transpeptidase enzymes that bind to them are sometimes called penicillin-binding proteins (PBPs). [3] Methicillin is actually a penicillinase-resistant β-lactam antibiotic. Penicillinase is a bacterial enzyme produced by bacteria resistant to other ...

    en.wikipedia.org/wiki/Linezolid

    Linezolid is an antibiotic used for the treatment of infections caused by Gram-positive bacteria that are resistant to other antibiotics. [9] [10] Linezolid is active against most Gram-positive bacteria that cause disease, including streptococci, vancomycin-resistant enterococci (VRE), and methicillin-resistant Staphylococcus aureus (MRSA).
