Table 3.
Antimicrobial activity of samples against S. aureus and C. albicans strains tested using by a modified microdilution method (a broth disk-diffusion method in broth with viable counting) (log-CFU/mL). The values are averages and SE (n = 3). Different letters near the means represent significant differences by Dunnett T3 test.
