Abstract

Abstract Firouzi, R, Azadbakht, M. and Nabinedjad, A. 1998. Anti-listerial activity of essential oils of some plants. J. Appl. Anim. Res., 14: 75–80. Minimal inhibitory concentration (MIC) of essential oils of plant Thymus daensis, Artemisia absintium, Matricaria chamommilla, Melissa officinalis and Allium sativum (garlic) against Listeria monocytogenes type 4a using tube dilution technique and agar disk diffusion method were studied In tube dilution technique the concentration of each oil was estimated in v/v units. The results showed that the MIC values for T. daensis, A absintium, M. chamommilla, M. officinalis and A. sativum, were 1:6400, 1:1280, 1:1280, 1:2560 and 1:1280, respectively. In agar disk diffusion test, the zone of inhibition were 25, 9, 10, 10 and 15 mm, respectively. The results showed that the antilisteric activities of essential oils of T. daensis and M. officinalis were superior than that of other essential oils.
