What is the strongest antibiotic for MRSA? Vancomycin is generally considered the drug of choice for severe CA- MRSA infections. Although MRSA is usually sensitive to vancomycin, strains with intermediate susceptibility, or, more rarely, resistant strains have been reported.

What is MRSA? MRSA is methicillin-resistant Staphylococcus aureus, a potentially dangerous type of staph bacteria that is resistant to certain antibiotics and may cause skin and other infections. As with all regular staph infections, recognizing the signs and receiving treatment for MRSA skin infections in the early stages reduces the

Is MRSA resistant to Zyvox?
Because MRSA is becoming more resistant, and it’s more common for antibiotic treatments to fail, and treatment may require the use of newer antibiotics, such as the “glycopeptides” which includes Vancomycin and Zyvox.

How to diagnose MRSA?
Doctors diagnose MRSA by checking a tissue sample or nasal secretions for signs of drug-resistant bacteria. The sample is sent to a lab where it's placed in a dish of nutrients that encourage bacterial growth. But because it takes about 48 hours for the bacteria to grow, newer tests that can detect staph DNA in a matter ...

How does methicillin resistance occur?
Methicillin resistance has occurred in S. aureusby mutation of a penicillin-binding protein, a chromosome-encoded protein. This type of resistance is transferred between S. aureusorganisms by bacteriophages. This is one of the only medically relevant examples of chromosome-mediated drug resistance by phage transduction.
