In vitro antimicrobial activity of purified fractions from the most active plant extracts tested against bacteria. Growth inhibition zones were measured and analyzed with mean ± standard deviation (SD), (n = 3) using one way analysis of variance. Level of significance at (*P > 0.01). Most of the fractions exerted a potent inhibitory effect against multidrug resistant Gram-negative bacteria (B. pseudomallei strains KHW and TES), K. pneumonia, and Gram-positive bacteria S. aureus.
