* strains-isolates; nd—not detected, meaning resistance R in the tested range of concentration (1.25–50 µL/mL); ↑—higher than the highest value applied MIC—minimum inhibitory concentration; MBC—minimum bactericidal concentration; MFC—minimum fungicidal concentration; Str—streptomycin; Amp—ampicillin; Tet—tetracycline; Cef—cefuroxime, Nyst—nystatin; a, b, c, d, e, f —letters means significant differences between antimicrobial activity within strain of bacteria determined by Tukey HSD test, at p < 0.01. In each row different letters mean significant differences.
