Evaluation of Zenian and Avishan-e Shirazi Antibacterial Activity against Vibrio cholerae Strains

The aim of this study was to determine the antibacterial activity of Zataria multiflora Boiss (Avishan-e Shirazi) and Carum copticum (Zenian) extracts on Vibrio choleraee American Type Culture Collection (ATCC14035) and V. choleraee Persian Type Culture Collection (PTCC1611) strains. Antimicrobial effects of the extracts were assayed by disc diffusion and broth microdilution methods. Using susceptibility tests, it was shown that Carum copticum methanolic extract had the highest antibacterial effect on V. choleraee standard strains at 6.25 mg/ml concentration. Other evaluations considering herbal extracts as an antibacterial agent as well as in vivo examination of these extracts is needed to provide a natural, cost effective and strong alternative for traditionally less effective antibiotics normally used.
