Abstract
Biofilm formation is a major threat to the society, as it adds to the severity of bacterial infection making antimicrobial agents ineffective. In the present study, the antibacterial and antibiofilm activity of Zingiber officinale Rosc. (Ginger) rhizome essential oil (EO) was evaluated against multi-drug resistant (MDR) Escherichia coli (3.125 μl/ml) Klebsiella pneumonia (3.125 μl/ml), Enterococcus faecalis (0.78 μl/ml) and Staphylococcus aureus (1.56 μl/ml) bacteria. Percentage of biofilm inhibition by EO was found to be highest against S. aureus (94 %) followed by K. pneumoniae (91 %), E. coli (89 %) and E. faecalis (83 %). This antibiofilm activity study of ginger EO may be used in research to translate into product against various MDR pathogens.
