A MRSA staph infection is an infection in which the staph bacteria becomes resistant to common antibiotics. It is also called methicillin-resistant Staphylococcus aureus, states Mayo Clinic.
Although not a common occurrence, some MRSA infections will often strike those who have spent a lot of time in the hospital, a nursing home or a dialysis center. Another type of MRSA occurs in people who have close skin-to-skin contact with others. Homosexual men are at higher risk for developing MRSA infections than any other part of the population.
A MRSA infection is serious, although it does not look serious in its initial stage. The infection starts as small red bumps that can get mistaken for pimples or insect bites. From there, they quickly become very painful and require surgical draining. In most cases, the bacteria that causes MRSA remains on the skin, but it has been known to dig deeper into the body and affect bones, joints, heart vales and the lungs.
A person diagnosed with a MRSA infection must seek treatment right away and never try to treat the infection alone. To test for MRSA, doctors will take a tissue sample or check nose secretions for the presence of the staph bacteria. It may take up to 48 hours for these test results to provide a diagnosis, according to Mayo Clinic.
