Abstract
The ability of bacteria to develop resistance to antibiotics has become a signification problem in the treatment and control of diseases. Some of the plants however, show antibacterial effects. The extracts of these plants are natural products and do not cause any risk to human body and could be replace antibiotics. In this study we investigated the antibacterial effects of Allium hirtifolium, A. kharputens and A.chrysantherum on three strains of bacteria: Staphylococcus aureus, S.epidermidis, Escherichia coli. The plants were collected from vicinity of urmia, Mahabad and Sardasht in west Azerbaijan. “Disk Diffusion Method” used the extracts of dry bulbs against bacteria. The samples matched with antibiotics recently recommended against our selected bacteria. The result showed that the extracts of Allium hirtifolium had high effect on all the three bacteria but extract of two other plants had not a significant effect on used bacteria.
