In Vitro Antibacterial Effect of Various Berries on Listeria monocytogenes as Food Borne Patogen

Listeria monocytogenes is a food borne pathogen and causes illnesses with high mortality rate in susceptible populations. It often incriminated outbreaks of human listeriosis. Increasing interest the health benefits various berries has led to investigation their antibacterial activity. Causative agent can multiply at refrigerator temperatures, resistant disinfectants, adheres surfaces. Native were assessed for ability inhibit growth bacteria L. monocytogenes. Extracts powder – sea buckthorn (Hippophae rhamnoides L.), rosehip (Rosa canina black chokeberry (Aronia melanocarpa (Michx.) Elliott), grape marc (Vitis vinifera L.) hawthorn (Crataegus oxyacantha used. All plant materials come from Rudi-Arionești Natural Complex Republic Moldova 2017–2019. In previous studies it been found that buckthorn, rosehip, chokeberry, have antimicrobial effects on pathogenic microorganisms responsible alteration. Bacteria showed varying susceptibilities berry fruits. Antimicrobial properties evaluated using well diffusion method broth dilution method. According results obtained, was most pronounced effect monocytogenes, diameter inhibition zone being 32 mm, followed by samples 26 mm. The minimum concentration (MIC) bactericidal (MBC) determined.
