Introduction: Traditional medicines become main source of primary health in different part of Sudan as result of cost effectiveness and viability of antibiotic in addition of antibiotic resistance and their side effect
Method: water, methanol and ethanolic extracts of Lemongrass were screened for in vitro antibacterial activity against (Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris, Serratia marcescens Providencia spp, Salmonella spp, Shigella spp, Pseudomonas aeruginosa, Staphylococcus auras, Staphylococcus albus) by disc diffusion method.
Result: extracts showed variable effect on the tested organisms. Ethanol leaves extract exhibit highest result to tested bacteria, whereas methanol extract had lowest activity. Water extract showed similar inhibition zones to the all tested bacteria with advantage to gram positive bacteria.
Conclusion: The results obtained in the present study indicate that extracts of lemongrass had potential antibacterial activity against tested bacteria.
