Study finds MRSA strain resistant to treatment

Accreditation Connection, November 9, 2009

One strain of Methicillin-resistant Staphylococcus aureus (MRSA), USA600, has been found to be partially immune to an antibiotic that is used to treat the condition, according to HealthDay.com. MRSA causes infections in the skin and bloodstream, and can infect surgical wounds and pneumonia.

Half of the patients who developed this strain died within a month, which is five times faster than other people infected with MRSA are. These statistics were presented at the Infectious Diseases Society of American, held October 29 through November 1, in Philadelphia, PA.

Researchers believe that the USA600 strain is unique and that the age of the patient could play a part in whether antibiotics can treat the infections or not. Patients who developed the USA600 strain averaged around 64 years of age, as compared to 52 years of age.
