Abstract

  The effect of the  sub-inhibitory concentrations of Acanthospermum hispidum extract on the activities of amoxicillin and ciprofloxacin was assessed by the Kirby-Bauer disc diffusion method. The extract demonstrated antibacterial activity against Staphylococcus aureus, Klebsiella pneumoniae, Bacillussubtilis,Salmonella thyphi, Proteus vulgaris and Pseudomonasaeruginosa with MICs ranging between 11 and 53 mg/ml.  A 5 mg/mlextract enhanced significantly (p<0.05) ciprofloxacin activity (up to 38 folds) against all the test bacteria except P. aeruginosa. Amoxicillin activity was also potentiated significantly (p<0.05) against Staph. aureus (9fold) and B.Subtilis (12 fold). A. hispidum appears to contain phyto constituents that may be useful adjuvant for antibiotic  formulations.

Key words: Sub-inhibitory concentration, antibacterial activity, amoxicillin,ciprofloxacin, A. hispidum.
