The antimicrobial activity of Cupressus arizonica essential oil [1] was tested against three bacterial strains: Staphylococcus aureus (ATCC 25923), Escherichia coli (ATCC 25922) and Staphylococcus epidermidis (ATCC 14990) using the agar disk-diffusion method. The antibacterial effects of the essential oil towards the tested bacteria were studied via the presence or the absence of inhibition zones, MIC and MBC values. Chloramphenicol and fluconazole were used as reference for the antibiotic activity. Staphylococcus aureus had an inhibition area that measured 30 mm for the Cupressus arizonica essential oil. In comparison, the same bacteria measured 30 mm in chloramphenicol 30 µg test and 0 mm for fluconazol 25 µg test. Escherichia coli area of inhibition measured: 15 mm for Cupressus arizonica essential oil, 30 mm for chloramphenicol 30 µg, and 15 mm for fluconazol 25 µg. Staphylococcus epidermidis had the following inhibition measurements: 12 mm for Cupressus arizonica essential oil, 30 mm for chloramphenicol 30 µg and 0 mm for fluconazol 25 µg. judging by these results, we can say that Cupressus arizonica essential oil has lower effect as chloramphenicol substance over the Staphylococcus epidermidis and Escherichia coli. Staphylococcus aureus had the same sensitivity to the Cupressus arizonica essential oil as well as to chloramphenicol, creating a 30 mm of inhibition area. The essential oil has proven more powerful antibacterial effects than floconazolol for all three bacterial strains analyzed. In this in vitro study, we have shown that Cupressus arizonica essential oil can be efficient as an antibacterial agent.
