Study the Antibacterial Activity of Zingiber officinale roots against Some of Pathogenic Bacteria

Abstract

In this study aqueous extract of ginger (Zingiber officinale ) Roots were used for antibacterial activity against various Gram-negative and Gram-positive bacteria (Klebsiella pneumoniae, Proteus vulgaris, Streptococcus pyogenes and Staphylococcus aureus). growth inhibition was evaluated by the disc diffusion. The extract of ginger (G) showed clear antibacterial activity against pathogenic bacteria, which this activity was enhanced with the increasing of concentrations belongs to them. The latest concentration (0.4mg/ml) of the extract gave highest activity against Klebsiella pneumonia, Proteus vulgaris, Streptococcus pyogenes and Staphylococcus aureus . Antimicrobial activity of ginger extract was compared with a number of antibiotics (A) that known for their ability include, nalidixic acid, trimethoprim, chloromphenicol, gentamicin and erythromycin by using antibiogram test. Antimicrobial activity of latest concentration of ginger was better than that to Chloromphenicol, Gentamicin against Klebsiella pneumoniae, Proteus vulgaris, Streptococcus pyogenes and Staphylococcus aureus
