This Study aimed to investigate the effect of garlic extract against multidrug resistance ofStaphylococcus aureus and E. coli isolated from urine. Isolates were identified by usingbiochemical tests. The susceptibility of these microorganisms towards the most effectiveantibiotics were studied by using disc diffusion method. The multidrug resistancemicroorganisms were challenged with garlic extract using serial dilutions and the technology ofELISA spectrophotometer. The results of this study

... d that ten isolates of E. coli and eightisolates of Staphylococcus aureus out of sixty isolates were resistant to all antibiotics. Garlicextract significantly inhibits the growth of these bacteria in a concentration independent manner.This study showed that garlic extract exerts a promising antibacterial effect against multidrugresistance of Staphylococcus aureus and E. coli.
