Biofilm and swarming motility among multidrug-susceptible (MDS) and multidrug-resistant (MDR) P. mirabilis strains. A statistically significant difference was observed between MDS and MDR P. mirabilis strains in terms of biofilm formation on the glass (chi-square test, p = 0.0161) and swarming motility (chi-square test, p = 0.0001) measured in a three-stage scale (Graph Pad Prism v. 6). Biofilm scale: 1, lack of biofilm, single cells observed; 2, single microcolonies of biofilm; 3, biofilm covering the entire coverslip. Swarming motility scale: 1, weak swarming (coverage < 5%); 2, medium swarming (5– ≤ 25%); 3, intensive swarming (25– ≤ 50%).
