Microbiology: Methicillin-resistant Staphylococcus Aureus (MRSA)

Methicillin-resistant Staphylococcus Aureus (MRSA)
  • a strain of Staphylococcus Aureus, a gram-positive coccus
  • a very dangerous and easily transmitted nosocomial pathogen-->transmitted from healthcare worker to healthcare worker, healthcare worker to patient, and patient to patient
  • accounts for 40% of nosocomial staphyloccus aureus infections (note: resistant strains develop esp. in hospitals due to the large amounts of antibiotics given to patients)
  • spread by contact, usually by the hands of healthcare workers (25% of healthcare workers are suspected to be carriers of MRSA)
  • colonizes in the anterior nares, axilla, perineum, and inguinal area
  • community-acquired MRSA--> not as aggressive as hospital-acquired MRSA; susceptible to many antibiotics

  • Newborns
  • Elderly clients
  • Breast-feeding women (may develop mastitis)

  • Clients with chronic medical illness
  • Clients with invasive, in-dwelling devices (foley catheters, IV catheters)
  • Clients in the ICU
  • Clients on prolonged hospitalisation
  • Clients on prolonged antibiotic therapy
  • Clients exposed to MRSA carriers
