MRSA Infection

MRSA Infection,  also known  as, Methicillin-resistant Staphylococcus aureus infection is caused by an evolved strain of Staphylococcus aureus bacteria that is resistant to most antibiotics that are usually used to treat Staphylococcal infections. MRSA is resistant to Beta-Lactam types of antibiotics like methicillin, oxacillin, penicillin, and amoxicillin.

MRSA Symptoms and Pathway

MRSA infection manifests differently, depending on the organ it infects. The condition commonly infects the skin where it starts as an innocent red bump or boils and later turns into a deep and painful abscess which may require surgical drainage. MRSA of the skin may complicate to life-threatening infections of the bones, joint, surgical wounds, blood stream, heart valves and lungs.

Culture and sensitivity tests of nose aspirates or tissue biopsy samples will propagate bacterial growth for microscopic diagnosis. DNA test kits for MRSA may be now available for quicker diagnosis.


There are still cases of MRSA that still respond to certain antibiotics like Vancomycin. Culture and Sensitivity test will reveal the antibiotic of choice that the bacteria may still be responsive. Some surgeons may just go ahead with the surgical drainage of the abscess, rather rely on antibiotic treatment.


People with MRSA may have a poor outcome in terms of post surgical infections and hospital re-admissions. Because MRSA has many antibiotic resistances, the financial burden and outcome to the individual may also be devastating. Mortality rate and morbidity rate with MRSA infection is above average when compared to any other body infections. MRSA infection should be taken seriously because this may cause a serious outbreak. Individuals with Staphylococcal infections should complete dosage of antibiotics, and should refrain from sharing antibiotics with peers that may present similarly to prevent the development of further drug resistance.
