Abstract: Based on ethno pharmacological literature, four medicinal plants from Combretum genus used in traditional medicine in Sudan were collected. Extracts of different polarities were tested in preliminary biological screening for their invitro antibacterial activity against 2 standard Gram-positive bacteria (Bacillus subtilis and Staphylococcus aureus) and three standard Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa and Proteus vulgaris). The active extracts were further tested against seventy clinical isolates and their Minimum Inhibitory Concentrations (MIC) were also determined. The results of the activity of standard antibiotics against the tested organisms were reported.
