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.
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.
In situations where the incidence of MRSA infections is known to be high, the attending physician may choose to use a glycopeptide antibiotic until the identity of the infecting organism is known. After the infection is confirmed to be due to a methicillin-susceptible strain of S. aureus , treatment can be changed to flucloxacillin or even ...
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 bacterial life, by permanently binding to their active sites.
However, staph infections are still prominent and a cause for concern among healthcare professionals, especially new antibiotic-resistant strains. In the U.S., the incidence of staph infection is around 38.2 to 45.7 per 100,000 person-years, whereas other First World countries have an average incidence rate of 10 to 30 per 100,000 person-years.
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 ...
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 ...
Antibiotic sensitivity testing is also conducted at a population level in some countries as a form of screening. [4] This is to assess the background rates of resistance to antibiotics (for example with methicillin-resistant Staphylococcus aureus), and may influence guidelines and public health measures. [4]
