The antibacterial activity of Micromeria cilicica Hausskn. ex P.H.Davis, Micromeria dolichodontha P.H. Davis and Micromeria crenmophila subsp. amana (Rech. fil.) P.H. Davis was studied using the disk diffusion method and determination of minimum inhibitory concentration (MIC) values against Staylococcus aureus ATCC 6538P, Streptococcus sanguis PTCC 1449, Escherichia coli ATCC 1 1230, Pseudomonas aeruginosa ATCC 27583 and Klebsiella pneumoniae UC57. The methanol and chloroform extracts of the aerial parts of M. cilicica. M. dolichodontha and M. cremnophila subsp. amana exhibited concentration-dependent antibacterial activity against all tested bacteria.
