Medicinal plants acquired great attention for their miracle properties against various human illnesses. In this laboratory-based study, Antibacterial effectiveness of Curcuma longa and Zingiber officinale (Ginger) were extracted in aqueous, 70% ethanol and ethyl acetate solvents and investigated against 13 various American type culture collection (ATCC( strains by the mean of determining the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). Results demonstrated that ethyl acetate extract of Curcuma longa was superior to other solvents versus Enterococcus faecalis, Enterococcus faecalis (VRE), Staphylococcus aureus (MRSA) and Staphylococcus epidermidis with inhibition zones range (12-19mm) and exhibited killing concentration varies between 25-50 mg/ml. Acinetobacter baumannii expressed visible sensitivity to Curcuma longa extracted in aqueous, ethanol and ethyl acetate solvents. Bactericidal activity was experimentally constant at a concentration of 50mg/ml. Ethyl acetate extract of Ginger, on the other hand, was the only extract that showed antibacterial activity against three reference bacterial strains include E. faecalis, S. aureus and Staphylococcus aureus (MRSA), with inhibition zones range (12-19mm) and MBC value of 100, 12.5 and 25 mg/ml, respectively. In conclusion, demonstrated antibacterial activity of Curcuma longa and Zingiber officinale can be further invested as potential natural antibiotics against some multi-resistant pathogens.
