Colorized scanning electron micrograph of a human neutrophil ingesting MRSA. 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.
However, only approximately 50% of the human population are carriers of S. aureus, with 20% as continuous carriers and 30% as intermittent. This leads scientists to believe that there are many factors that determine whether S. aureus is carried asymptomatically in humans, including factors that are specific to an individual person.
ST8:USA300 is a strain of community-associated methicillin-resistant Staphylococcus aureus that has emerged as a particularly antibiotic resistant epidemic that is responsible for rapidly progressive, fatal diseases including necrotizing pneumonia, severe sepsis and necrotizing fasciitis. [1]
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 ...
Staphylococcus aureus. MRSA ST398 is a strain of the gram-positive bacterium Staphylococcus aureus, which belongs to the genus Staphylococcus. This genus covers a large group of gram-positive bacteria that are classified taxonomically in the family Staphylococcaceae, order Bacillales, class Bacilli, and phylum Firmicutes.
[36] [37] [38] In the community, otherwise-healthy people can become persistent skin carriers of MRSA, or faecal carriers of enterobacteria strains which can carry multi-antibiotic resistance factors (e.g. NDM-1 or ESBL-producing strains). The risks are not apparent until, for example, they are admitted to hospital, when they can become "self ...
REDUCE MRSA, which stands for Randomized Evaluation of Decolonization vs. Universal Clearance to Eliminate methicillin-resistant Staphylococcus aureus (MRSA), was completed in September 2011. [3] This study determined decolonization with chlorhexidine and mupirocin of all patients without screening was the most effective method of reducing the ...
