Positive MRSA’s shall be tested for Staphylococcus type A (Spa-typing). The typing shall be performed at the NRL or under its supervision, or isolates shall be forwarded to the CRL-AR, which shall then perform the typing.

On a subset of representative isolates (about 2 % of the number of pooled samples) MLST-typing shall be performed by the NRL or the CRL-AR.
