Objective of the research was to validate the potential of Syzygium aromaticum and Kaempheria galanga against biofilm formation and plasmid borne drug resistance exhibited by Pseudomonas spp. Antimicrobial property of and on culture was assessed using the agar well diffusion method. Crystal violet assay was employed to determine the percentage inhibition of biofilm by the extracts following generation of biofilm on multiwell plates. The decrease in Pseudomonas viability in an established biofilm after treatment was determined by standard MTT reduction assay. Fluorescent microscopy following staining with Ethidium bromide and Acridine orange was done to distinguish the dead and live cells in the biofilm. Finally, antiplasmid activity was established by agarose gel electrophoresis. The extracts were found to have potent antibacterial activity and inhibited biofilm attachment to polymeric surfaces. | Anti biofilm and anti plasmid activites of Syzygium aromaticum and Kaempheria galanga against pseudomonas aeruginosa
