Effect of origanum majorana on some hospital resistant microbes and reference bacterial strains

ABSTRACT

The antimicrobial activity of marjoram essential oil was determined using Staphylococcus aureas ATCC 6923, Pseudomonas auregonosa ATCC 9027, Bacillus subtilis ATCC 6633, E. coli ATCC 8736, and two hospital resistant microbes isolates 16 and 21, marjoram oil was found to be effective against used pathogenic bacteria. The chemical composition of the essential oil was analyzed by GC-Ms. The major components were Terpineol, cis-beta, Alpha-terpieol, l-terpinen-4-ol. Linalool and I, 6-octadien-3-ol, 3. 7 dimethyl-, 2aminobenzoate. Inhibition was observed at concentration [4-7 micro l/ml] with reference strain and [10 - 15 micro l/ml] with hospital resistant microbes using disk diffusion and micro dilution methods:
