Genetic variation protective against MRSA infection


New research has suggested that an inherited genetic trait appears to protect some individuals from MRSA infections.

The study, published recently in the Proceedings of the National Academy of Sciences, adds important insights into the genetic factors that predispose some patients to persistent MRSA infections, and could lead to improved treatment options in the future.

 The team, led by researchers from Duke Health (NC, USA), analyzed two cohorts of patients, matching them by age, sex, health conditions and risk factors for MRSA infections. In total 68 participants were identified, half of which had persistent MRSA infection and half of which had cleared the infection from their bloodstream.
