Information about MRSA

What is MRSA?

MRSA or Methcillin Resistant Staph Aureus is a bacteria resistant to the penicillin family of antibiotics. The presentation is usually skin lesions, boils, abscesses that may have started as a cut or scratch. Frequently these are treated with broad spectrum antibiotics without success. Once cultured, the bacteria can be identified and treated with appropriate antibiotics. Frequently in debilitated patients the bacteria can cause a form of pneumonia.

The bacteria has the ability to alter its structure to make it resistant to the usual antibiotics. This occurs due to multiple reasons. Food and water supply containing antibiotics, overuse or inappropriate use of antibiotics, and treated hospital infections have led to the development of these bacteria. Certain other antibiotics also have led to the proliferation of resistant bacteria.

How can one prevent MRSA?

The best way to prevent MRSA is good hygiene, especially frequent hand washing. This is extremely important in healthcare workers as the bacteria is transferred from one to another through skin to skin contact. Ask health care workers to wash their hands before seeing you, especially in the hospital setting.

It is important to note that the bacteria is NOT transferred through the air, but can be transferred through sharing towels, poor hygiene, living in unsanitary conditions, and contact sports. Learn to recognize the lesions and seek medical attention soon in order to get early treatment.
