counts for the extract ranged between 0.18log10 and 0.35log10 cfu/ml for P. aeruginosa, 0.27log10 and 1.95log10 cfu/ml for S. aureus and 0.27log10 and 0.45log10 cfu/ml for E. coli after 10 h interaction at 0.5x MIC and 1x MIC. Most of the extracts were rapidly bactericidal at 2x MIC achieving a complete elimination of most of the test organisms within 12 h exposure. A good correlation was found between the killing curves and the MIC of A. nilotica against the test organisms.
