Pulsed-field gel electrophoresis (PFGE) of the SmaI-fragmented genomic DNA of MRSA isolates recovered from healthy and infected dogs in the state of Rio de Janeiro (red circles). (A) Dog isolates from Rio de Janeiro city and (B) dog isolates from Campos de Goytacazes city. USA100, USA300, USA400, WB45 and WB69 (USA1100), and BMB9393 and HU25 (BEC) were representatives of the MRSA international clones used for comparison purposes (blue circle). Dendrograms were generated from the PFGE patterns using GelCompar II software version 6.5.
