^a Biofilm formation assay data is the mean of three independent experiments carried out in triplicate ± standard deviation following growth in minimal (EAOB) or rich (TSB) media at 21 or 37°C under dynamic or static conditions, respectively.

^b Biofilm formation (BF) was classified as non-adherent (N), weakly (W)-, moderately (M)- or strongly (S)-adherent using previously described criteria [12].
