Abstract

Aqueous and ethanolic extracts of Zingber officinale had antimicrobial activitly against large  number of pathogenic bacteria and fungi. Aqueous extract of Nigella saliva possessed antibacterial activity in higher concentration. In addition all fractions of both Zingber officinale and Nigella sativa exhibited antimicrobial activities against various microorganisms. Saponin and oil fractions of the test plants increased the anitbacterial acitivity of ampicillin against pyogenic microorganisms while resin fraction decreased that activity.
