Abstract
The alarming increase in bacterial resistance to antibiotics caused some authors to state that we are approaching a post-antibiotic era and medical catastrophe, the study aimed to assess the antimicrobial effects of selected plant extracts against several sensitive and resistant bacterial isolates. Ex-perimental cross-sectional study was conducted, 70% ethanol crude Acac-cia nilotica, Trigonella foenum-graecum, Punica granatum and Commiphora myrrha extract was prepared and several commercial antimicrobials agent tested, the antibacterial activity was investigated using the disc diffusion method. The inhibition zones' diameters (mm) were calculated and inter-preted by Zone Diameter Interpretative Standards. Data were analyzed by using (SPSS) software version 22. About 200% of A. nilotica and T. foenum-graecum showed bactericidal effects against Enterococcus faecalis, means +/- SD (12.3 +/- 2.8 and 12.5 +/- 2.1). The activity of 200% C. myrrha extract was highest against all diverse bacterial. Despite a relatively high inhibition zone among all plant ethanol extracts, the findings demonstrate that there is no statistical significance in the inhibitory activity impact of varying concentra-tions of 70% ethanol extracts of all plants extract against bacterial isolates (P. value >= 0.05). The outcomes of the ethanol extracts of the used plant un-der study demonstrated that the herbal extract can be a superior antimicro-bial potential than the result of the commercial broad spectrum antimicro-bial agent utilized. C. myrrha extract was potent antimicrobial activity against all diverse bacterial species.
