Staph bacteria are like any other organism, in that they evolve to improve their odds of survival, and they do this quite quickly. Given good nutrient source to reproduce, a bacterium can divide into two new cells in about 30 minutes. Over the years staph developed so much resistance to penicillin, that nearly all are resistant to typical penicillins like Penicillin G and V, and Amoxicillin.
One of the most troublesome of these bacteria has been Staphylococcus
aureus. Two factors seem to have combined to produce this germ. First, this strain of staph is more virulent, or invasive and aggressive at infecting people. Second, many of the staph of this virulent strain have developed resistance to even the new commonly used special synthetic beta-lactamase resistant penicillins, like Methacillin. This
problematic bacteria is called Methacillin-Resistant Staphlococcus Aureus
or more commonly MRSA.
MRSA has led many people to developing skin infections and abscesses with bacteria that are difficult to control and let the body heal from the infection. Even more difficult is the eradication of the tough staph germ from the normal skin and nasal passage flora, making recurrent MRSA infections very common. Older antibiotics still have some effectiveness against MRSA such as doxycyline, minocycline, and some sulfa drugs, but the primary treatment for MRSA abscesses is to surgically drain the abscess. This allows the body to fight the infection better. Many regimens have been developed to try to eradicate the body of the MRSA, with mixed efficacy.
Staph or MRSA infection often
looks like a pimple or boil that can be red, swollen, and
painful. If you think that you may have a skin infection or
possibly MRSA, the most important thing to do is come into the
office and seek early treatment, before the skin infection
involves large areas or invades deep skin structures.
For any further questions, I
recommend the Pierce County Health Department brochure available
with suggestions for patients who have developed MRSA
infections. You can download that document at
