Pathophysiology: Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium responsible for several difficult-to-treat infections in humans. It is also called oxacillin-resistant Staphylococcus aureus. MRSA is especially troublesome in hospitals, prisons, and nursing homes, where patients with open wounds, invasive devices, and weakened immune systems are at greater risk of nosocomial infection than the general public.S. aureus most commonly colonizes under the anterior nares.
Statistics: A total of 26310 isolates were included in the study. The overall prevalence of methicillin resistance during the study period was 41%. Isolation rates for MRSA from outpatients, ward inpatients and ICU were 28, 42 and 43% respectively in 2008 and 27, 49 and 47% respectively in 2009.
Treatment: Minor skin and soft tissue infections, such as smaller boils or abscesses, may only require a treatment called incision and drainage.Incision and drainage involves piercing the tip of the boil or abscess with a sterile needle or scalpel to drain the pus and allow the affected area to heal. Before the procedure, you're likely to be given a local anaesthetic to numb the affected area.
Major Research: Some semi-toxic fungi/mushrooms excrete broad spectrum antibiotics, not all of which have been fully identified; some have been shown to inhibit the growth of Staphylococcus aureus. An entirely different approach is phage therapy (e.g., at the Eliava Institute in Georgia). Experimental phage therapy tested in mice had a reported efficacy against up to 95% of tested Staphylococcus isolates.
