they can not be killed by Methicillin, or nay relative of that drug. MRSA has a great ability to develop resistance's against many drugs. For example, penicillin's, tetracyclines, aminoglucosides and glycopeptides to name a few. If a bacteria mutates in such a way that it will no longer be able to be killed by a drug class it is said to be resistant. Despite that fact that there are currently over 160 antibiotics on the market(2), it will not take long for a bacteria to be totally resistant to all the drugs that target it. Thus the patient who is infected with the bacteria will ultimately succumb to the infection resulting in death.
MRSA is especially important in health care settings in that it can be passed form one patient to another with very little effort. The number one proven way to restrict the transmission of MRSA is through diligent handwashing. The handwashing must start with the primary caregivers as well as housekeepers, maintenance personal or anyone that could have contact with the patient or the patients belongings. Patients can carry MRSA in many locations. For example, some patients are completely asymptomatic but can be highly colonized in the nose, pharynx, rectum, wounds or chronic skin lesions. These people are unaware that they are MRSA positive and there for so are the medical personal that are taking care of them. Staff members may be carriers as well ant transmit MRSA to
patients by hand contact, either direct or indirect. Those with a more severe underlying disease or those with and increased number of operations are more susceptible to contract MRSA from a carrier.
Once MRSA has been established in a hospital, it may be very difficult to eradicate. For that reason there is wide spread belief that patients with MRSA sho
