The present study shows the antibacterial activity of Cymbopogon citratus and Rosmarinus officinalis essential oils. The essential oil from the dried leaves was extracted by Hydrodistillation. the disc diffusion test was performed as antibacterial tests. Monoterpene hydrocarbons were the dominant compounds in Cymbopogon citratus oil, camphora,-pinene, g-terpineol and 1,8-cineole were the major compounds in Rosmarinus officinalis oil. Cymbopogon citratus oil revealed a good antimicrobial activity against carbapenems resistant Klebsiella pneumonia strains while no Rosmarinus officinalis  activity was acheived. The findings suggest possibility of application of Cymbopogon citratus oil in treatment of the nosocomial infections caused by this microorganism.
