communis fruit, Eucalyptus globulus leaf, and Cananga odorata flower essential oils. Essential oil samples were analysed by GC
chromatography coupled with FID detector (Agilent 6890N). The plant essential oils were tested regarding their antioxidant activity and
antimicrobial activity against 13 species of Gram positive (G+
) and Gram negative (G-
) bacteria isolated from human semen and
identified by MALDI-TOF MS Biotyper. Isolated G+ and G- were tested for antibiotics resistance Among tested bacteria, the lowest
antibiotic susceptibility for Corynebacterium species were observed for ciprofloxacin in three cases, for gentamycin in three cases, for
vancomycin in two cases and for tetracycline in five cases. Antioxidant activities tested using DPPH method reveals that Cannaga
odorata had the higher antioxidant activity and the lowest was found at J. communis essential oil. Antimicrobial activities showed that
all the essential oils inhibited on the entire 13 species of Gram positive (G+
) and Gram negative (G-
) bacteria being used. However, C.
odorata have the best antimicrobial effect against Corynebacteria. Good antimicrobial activity of C. paradise was found against
Corynebacteria also. Strong antibacterial activity of C. odorata against E. coli, E. faecium, P. aglomerans, P. fulva and S. agalactiae
were found.
