Dendrogram produced by comparing banding patterns on PFGE of Enterococcus spp. (A) and E. coli (B) isolated from dogs’ superficial surgical site (red); surgeons’ hands (green), and operation room (blue). The dendrogram was generated using the UPGMA clustering method in BioNumerics 7.1 software. The Dice coefficient and optimization was set at 1%. PFGE similarity cutoff of 90% (dashed line) was applied. Red squares highlight the genetically related isolates. *Note: Species and genes names are not italicized due to software limitations (BioNumerics 7.1). Abbreviations: G1 = clean/clean contaminated surgery; G2: contaminated surgery; SS: dogs’ superficial surgical site; SSI: surgical site infection; Env: environment; Surg: surgeon
