METHICILLIN-RESISTANT STAPHYLOCOCCUS-AUREUS - AN OVERVIEW

Methicillin-resistant strains of Staphylococcus aureus (MRSA) cause life-threatening infections, but they are no more pathogenic than methicillin-sensitive strains. Difficulties occur because of incorrect or missed identification of MRSA, and hence inappropriate or ineffective treatment of infections. Therapeutic options are severely limited and the increasing spectrum of resistance in MRSA is worrying. However, new methods of detection and new agents for treatment are being developed in response to the challenge of MRSA. Whilst the organism is a problem and control measures are necessary to contain its spread, the outlook is not bleak. In the medium term, the development of new, effective anti-MRSA agents should prevent the threat of MRSA becoming any greater in the field of hospital infection control.
