What we do

The National Meticillin-Resistant Staphylococcus aureus (MRSA) Reference Laboratory (NMRSARL) provides a national service to microbiology staff in Irish hospitals on MRSA isolates for:

  • epidemiological typing
  • antibiotic resistance detection {especially confirmation of meticillin resistance}
  • routine monitoring of the MRSA population in Irish hospitals.

Advice is provided on:

a) treatment through NMRSARl’s medical director
b) laboratory aspects of MRSA through NMRSARL’s scientific staff.

Referral Procedure

NMRSARL investigates MRSA isolates from microbiology laboratories in Irish hospitals.  NMRSARL does not investigate patient specimens for MRSA.  Send fresh subcultures on nutrient agar slopes from 18-h subcultures grown in pure culture on blood agar as soon as possible after isolation (or fresh subcultures from isolates stored at or below -20°C).  Isolates must be accompanied by NMRSARL laboratory investigation forms.  Please contact NMRSARL before sending isolates for outbreak investigation and/or for a supply of forms.
