The antibacterial effect of some selected algerian plants like Cyndon dactylon (L) pers were evaluated on several bacterial strains : Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATTC 27853, Staphylococcus Coagulasse (ATTC 5118), Staphylococcus aureus ATCC 25923, Klebcsiella pneumonie and  Enterococcus faecalis.The in vitro antibacterial activity was performed by agar disc diffusion method. The combination of Cyndon dactylon (L) pers with each of the standard antimicrobs E (Erythromycine), C (Chloramphenicol),  CTX (Cefotaxime),  AMX (Amoxicillin), CZN :  (Cefazoline),  CXN (Cefalexine) were most active  and showed significant  synergic effects. Moreover, Cyndon dactylon (L)/ other extracts of screened medicinal plants showed also high  synergic effects. The results obtained in the present study suggest that Cyndon dactylon (L) pers can be used in treating deseases caused by the tested organisms. Further chemical and pharmacological investigations may be carried out to isolate and identify the chemical constituents in the selected plants responsible for the antimicrobial activity. https://biomedpharmajournal.org/vol9no1/a-comparative-study-of-the-antibacterial-activity-of-cyndon-dactylon-l-pers-its-synergic-effect-with-some-of-the-standard-antimicrobs-and-extracts-of-some-medicinal-plants/ Cyndon dactylon (L) pers bacterial strains synergic effect extract
