Antimicrobial resistance
Videos
Antimicrobial resistance occurs when microbes evolve mechanisms that protect them from antimicrobials, which are drugs used to treat infections in humans, animals, and plants. Any microbe can develop
Antibiotic resistance tests: Bacteria are streaked on solid medium in Petri dishes and paper disks are laid on the surface, each impregnated with a different antibiotic. Clear rings, such as those on the left, show that bacteria have not grown around the disks, indicating that these bacteria are not resistant. The bacteria on the right are fully resistant to three of seven and partially resistant to two of seven antibiotics tested.

A number of mechanisms used by common antibiotics to deal with bacteria and ways by which bacteria become resistant to them
Methicillin-resistant Staphylococcus aureus is a group of Staphylococcus aureus strains that are resistant to β-lactam antibiotics. The β-lactam group is a broad-spectrum group of antibiotics that inc

…treatment (delayed or immediate antibiotic use). There are multiple national and international monitoring programs for drug-resistant threats, including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant S. aureus (VRSA), extended spectrum beta-lactamase (ESBL) producing Enterobacterales, vancomycin-resistant Enterococcus…

MRSA resistance to oxacillin being tested. The top S. aureus isolate is a control that is not resistant to oxacillin; the other three isolates are MRSA-positive.
