Figure 4.

Pulsed-field gel electrophoresis (PFGE) profiles of MRSA. Fourteen MRSA fingerprint patterns were identified for the 61 strains of MRSA isolated in an Orthopaedic Surgical Ward. These strains were collected from wound infections (n = 56); patient's nose (n = 50); and nose of the hospital workers attending wound infections (n = 50). Lanes 1, 9 and 17 represent S. aureus 8325 patterns for comparison. Lanes 2 to 16 barring 9 respectively represent PFGE banding patterns A to N.
