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

Figure 4

Comparison of ability of strong biofilm forming by S. aureus strains with icaABCD, icaABD, and icaAD genes. Values of absorbance at 492 nm were compared by using Kruskal-Wallis test. In analysis, multiple comparisons of average ranks at P ≤ 0.01 were used. The designation with different letters indicates that biofilm biomass formed by strains with different genes differs significantly.
