Many species of Zingiber have been investigated and found to contain several bioactive compounds, including the gingerols and shogaols, which have antibacterial activity [26,27]. Studies have revealed that a methanol extract of Z. officinale rhizomes possesses significant antibacterial activity against Escherichia coli, Salmonella enteritidis and Staphylococcus aureus [6]. Sivasothy et al. [7] evaluated the antibacterial activity of Z. officinale var. rubrum Theilade using the micro-dilution technique, which revealed that both the leaf and rhizome oils were moderately active against the Gram-positive bacteria Bacillus licheniformis, Bacillus spizizenii and S. aureus, and the Gram-negative bacteria E. coli, Klebsiella pneumonia and Pseudomonas stutzeri.
