Methicillin-resistant Staphylococcus aureus (MRSA) infection is caused by a type of staph bacteria that's become resistant to many of the antibiotics used to treat ordinary staph infections.
Most often, it causes mild infections on the skin, like sores, boils, or abscesses. But it can also cause more serious skin infections or infect surgical wounds, the bloodstream, the lungs, or the urinary tract. Though most MRSA infections aren't serious, some can be life-threatening.
Many people with active infections are treated effectively, and no longer have MRSA. However, sometimes MRSA goes away after treatment and comes back several times. If MRSA infections keep coming back again and again, your doctor can help you figure out the reasons you keep getting them.
MRSA most commonly causes relatively mild skin infections that are easily treated. However, if MRSA gets into your bloodstream, it can cause infections in other organs like your heart, which is called endocarditis. It can also cause sepsis, which is the body's overwhelming response to infection.
In summary, MRSA can be cultured from toilet seats in a children's hospital despite rigorous daily cleaning. This represents a potential risk to patients who may acquire it by fomite transmission from colonized persons, and represents a potential reservoir for community acquisition.
CA-MRSA is associated with infections transmitted through close personal contact with a person who has the infection or through direct contact with an infected wound. This type of MRSA infection may also develop because of poor hygiene, such as infrequent or improper handwashing.
In particular, clean any surfaces that could come into contact with uncovered wounds, cuts, or boils. In addition to cleaning surfaces, frequently cleaning hands and keeping wounds covered keeps MRSA from spreading. Large surfaces, such as floors and walls, have not been associated with the spread of staph and MRSA.
The risk of spreading MRSA through contact (touching, hugging, kissing) is low.
Sometimes MRSA can cause an abscess or boil. This can start with a small bump that looks like a pimple or acne, but that quickly turns into a hard, painful red lump filled with pus or a cluster of pus-filled blisters. Not all boils are caused by MRSA bacteria — other kinds may be the culprit.
Most MRSA skin infections clear up with treatment. MRSA is most dangerous if it enters the bloodstream. MRSA bloodstream infections can be serious. A bloodstream infection requires immediate medical attention.
Vancomycin or daptomycin are the agents of choice for treatment of invasive MRSA infections .
Vancomycin is generally considered the drug of choice for severe CA-MRSA infections. Although MRSA is usually sensitive to vancomycin, strains with intermediate susceptibility, or, more rarely, resistant strains have been reported.
For most staph infections, including MRSA, the incubation period is often indefinite if the organisms are colonizing (not infecting) an individual (see above). However, the incubation period for MRSA often ranges from one to 10 days if it enters broken skin or damaged mucous membranes.
MRSA infections can appear as a small red bump, pimple, or boil. The area may be tender, swollen, or warm to the touch. Most of these infections are mild, but they can change, becoming deeper and more serious.
The minimum dilution of ACV required for growth inhibition was comparable for both bacteria (1/25 dilution of ACV liquid and ACV tablets at 200 µg/ml were effective against rE. coli and MRSA).
Once the staph germ enters the body, it can spread to bones, joints, the blood, or any organ, such as the lungs, heart, or brain.
The skin is the part of the body most affected by the condition, as the bacteria can cause boils, blisters, hair root infection, and peeling skin. If not monitored or treated properly, MRSA can spread to affect the blood, bones, and major organs of the body like the heart and lungs.
Symptoms of a serious MRSA infection in the blood or deep tissues may include:
