Abstract:

The mode of antibacterial action of clove extract against Listeria monocytogenes and E.coli was studied. Intracellular ATP content, K+ and Na+ efflux and cell lysis were measured and cell damage was visualized using fluorescence and transmission electron microscopy. In conclusion, the cell death of Listeria monocytogenes and E.coli strains caused by of clove extract results from cell membrane damage.

Key words: clove extract, antibacterial mechanism, E.coli, Listeria monocytogenes
