Representative 2% agarose gel electrophoresis of spa gene HaeII restriction enzyme digestion PCR products, where M is DNA molecular size marker (100 bp ladder). (a) isolate 64 showing 2 bands spa gene PCR products (A) that remained uncut after (B) restriction, (b) isolate 1 showing single band spa gene PCR products (A) and the corresponding 3 bands HaeII restriction digestion pattern (B), and (c) isolate 62 showing 2 bands spa gene PCR products (A) and its corresponding 4 bands HaeII restriction digestion products (B).
