The study was conducted to determine the inhibitory effectiveness of different concentrations of lemon (Citrus lemon) and ginger (Zingiberofficinale) extracts on the Klebsiella and Proteus Bacteria. The outcome of this work was that the Klebsiella showed the highest inhibition at 75% concentration, 24mm of lemon extract and 20mm of ginger extract, while the proteus recorded the highest inhibition at 75% concentration of 21mm of lemon extract and 18mm of ginger extract. This conclusion was evaluated using Agar well-diffusion method; the results were compared with the effect of some antibiotics, mix lemon-ginger extract in equal proportions with the same previous concentrations, Different diameters were given and this was evident on Klebsiella and Proteus bacteria. The extract gave a strong efficacy at 75% concentration 28.25mm over the antimicrobial action that was used in int the study by respectively the highest inhibitor of Erythromycin 20mm on Klebsiella, while anti-Amikacin was 18mm on Proteus. The reached results were encouraging to conclude that in spite of the difference in the extent of their effect in inhibiting the bacteria growth. The lemon/ginger extract had a larger effect for inhibiting.
