Antimicrobial effects of the extracts of Zataria multiflora on the growth and multiplication of Listeria monocytogenes in milk using PCR.

In a series of experiments, the possible antimicrobial role of Zataria multiflora was assessed against Listeria monocytogenes. Results presented here show the effects of the herbal extract on excluding the microorganism in milk tank bulks at a concentration of 0.8 mg/ml, which was demonstrated in both minimum inhibitory concentration and PCR assays. Considering the importance of the transmissible antibacterial resistance among different bacterial strains, it can be suggested that the crude extract of Z. multiflora could possibly act as an anti- Listeria agent.
