Biofilm Formation by Methicillin-Resistant and Methicillin-Sensitive Staphylococcus aureus Strains from Hospitalized Patients in Poland

Figure 2

Comparison of ability of biofilm forming by MRSA and MSSA strains. Two group comparisons of average values of absorbance at 492 nm (A₄₉₂) were analyzed by using Mann-Whitney U-test. The designation with different letters indicates that biofilm biomass formed by MRSA and MSSA strains differs significantly at P = 0.000247.
