Investigation of antimicrobial activities of some sideritis species

This research has been conducted on tea grown in the western Mediterranean region and also consumption of Sideritis stricta condensate species, order to investigate their antimicrobial activity against 6 pathogenic bacteria. The plants were collected dried at room temperature flowering stage. essential oil was obtained with a Clevenger apparatus by hydrodistillation method. Antibacterial activities extracts determined disc diffusion In this method, MIC which showed antibacterial microdilution Staphylococcus aureus ATCC 29213, Escherichia coli 25922, Enterococcus faecalis 29212, Pseudomonas aeruginosa 27853, Salmonella enteretidis RSK 95046, Klebsiella pneumoniae 700613 used as test results evaluated according Clinical Laboratory Standards Institute (CLSI) criteria. Ampicillin penicillin positive control antibiotics. It that hot water both did not have activity. statistical analysis there significant difference (P<0.05) between condensate. found no ampicillin antibiotic. On other hand, condensata lower when compared
