What can you tell me about MRSA? VRSA?!

MRSA stands for methicillin resistant staph aureus. Staph aureus is a common cocci bacteria that causes some pretty bad infections. Its not too bad in pathogenicity, but can cause serious problems in immunocompromised, young or old patients. MRSA caused the same thing, its just resistant to the drug that doctors usually prescribe to fight it. This particular strand has become quite common within the past 5 years, and infects a great number of hospital patients.

MRSA grew a resistance to Methicillin, a derivative of penicillin which is growing more and more out of use due to resistance to it. Big whoop, we got a whole host of other drugs we can use to combat MRSA, Oxicillin for one. However, VRSA is another issue. There have not been a major case of VRSA yet, and thank god. Vancomycin is our last line of defense for resistant Staph, and if that were to spread, God help us.

Not sure what you really want to know. try googling it, you're sure to find something

Methacillin resistant staph aureus and I have only heard of VRE. Vancomycin resistant enterococcus. They are very strong bacteria that are hard to treat. MRSA is treated with Vancomycin and VRE is reistant to vancomycin. Can be deadly but IS able to be treated and is often treated sucessfully. MRSA and VRE is what results from antibiotic overuse and misuse. Colds and viruses cannot be treated with antibiotics but are often prescribed at the patience insistance and people often do not finish their antibiotics as prescribed for a bacterial infection which causes the strong bacteria to remain dormant and the next infection, the strong come out first which makes the whole thing harder to treat.
