Blatter, Zingiber officinale var. officinale (jahe gajah) and Zingiber officinale var. rubrum (jahe emprit) used by Malaysia traditional health care systems were screened for their antimicrobial activity against both Gram-positive bacteria and Gram-negative bacteria using agar disc diffusion assay. Approach: The efficacy of the extracts was compared to the commercially prepared antibiotic diffusion discs. Results: No inhibition was observed with the water fractions. Conclusion/Recommendations: None of the plants tested showed inhibition against Escherichia coli. Curcuma mangga showed some remarked inhibition against the bacteria used in this study.
