ERIC-PCR dendrogram created by GelJ^® software. The red dashed line indicates the 80% similarity cutoff. Clustering was performed using the UPGMA linkage and dice coefficient. The antibiotic resistance profile for each isolate is included, where black squares represent resistance, grey squares represent intermediate resistance, and white squares represent susceptibility. PG phylogenetic group. Biofilm formation categories are also included. S strong biofilm-forming isolate, M moderate biofilm-forming isolate, W weak biofilm-forming isolate, N non-biofilm-forming isolate
