Figure. Dendrogram showing the pulsed-field gel electrophoresis patterns after macrorestriction of genomic DNA with SmaI of methicillin-resistant Staphylococcus aureus (MRSA) isolates from the small animal hospital (SAH) and the equine hospital. The dog and human isolates (SAH staff) were identical to the UK major epidemic strain EMRSA-15, and the equine MRSA isolates (5 distinct profiles) were unrelated to EMRSA-15, EMRSA-16, or CMRSA-5. Profiles were analyzed with Molecular Analyst software (Applied Maths, Inc., Sint-Martens-Latem, Belgium) by unweighted pair grouping by mathematical averaging clustering method with a 2% tolerance window and using the Dice coefficient.
