Dendrogram of the pulsed-field gel electrophoresis (PFGE) profiles of SmaI-digested genomic DNA of 50 genetically unrelated Staphylococcus epidermidis isolates and associated characteristics. Similarities percentage is identified on a dendrogram derived from the unweighted pair group method using arithmetic averages and based on Dice coefficients. a B: Bloodstream infection isolates, N: Nasal isolates; b (+++): strong; (++): moderate; (+): weak: (): non-biofilm producer; c +: presence; −: absence; d I: arcA+/opp3AB+, II: arcA+/opp3AB-, III: arcA-/opp3AB+; −: negative; e −: not-detectable; na: not-applicable (methicillin-sensitive isolate); f na: not-applicable (methicillin-sensitive isolate); nt: non-typeable; g ST: sequence type; CC: clonal complex; S: singleton; NPF: none predicted founder
