Descriptive plot considering the interaction between species and membrane halos (p < 0.001). Values are mean ± SD from the assay in triplicate. M1 = membrane with RPE, sodium carboxymethylcellulose (NaCMC), without crosslinker agent (citric acid), M2 = with RPE, sodium carboxymethylcellulose (NaCMC) and 1× crosslinker agent (citric acid), M3 = with RPE, sodium carboxymethylcellulose (NaCMC) and 2× crosslinker agent (citric acid)] and P1, P2 and P3 (their controls, respectively) without RPE PAC = Pseudomonas aeruginosa (clinical), PAP = Pseudomonas aeruginosa (reference), SAC = Staphylococcus aureus (clinical), SAP = Staphylococcus aureus (reference) and SEP = Staphylococcus epidermidis (reference).
