Introduction: The use of herbal extracts is increasing because of the increase in bacterial resistance to conventional antibiotics. Plantago major is frequently used in traditional medicine because of its medicinal properties. The aim of the current study was to assess the antibacterial efficacy of an ethanolic extract of P. major leaves against Pseudomonas aeruginosa isolated from burn infections. Methodology: One hundred and twenty burn samples were collected from hospitalized patients at the Burn Hospital in Duhok city. The bacterium was identified using Gram stain, colony morphology, biochemical tests and selective differential media. Antibacterial activity of P. major leaves was assessed by using an ethanolic extract in serial dilutions of 100, 75, 50, 25, and 10 % and disc diffusion assay. Antibiotic susceptibility testing was also performed by disk diffusion using Muller-Hinton agar medium. Results: Different concentrations of the ethanolic extract of P. major leaves exhibited different zones of inhibition against P. aeruginosa from 9.93 mm to 22.18 mm in diameter. The inhibition zone increased as the concentration of the extract increased. The 100% ethanolic extract had the greatest inhibitory effect, inhibiting bacteria in the zone of 22.18 mm diameter. This bacterium showed a high level of resistance to the antibiotics used. Conclusions: This study demonstrated that herbal extracts could be used as a combination therapy with antibiotics and chemical drugs in the elimination of bacterial growth. Further investigations and future experiments, need to be carried out before recommending use of herbal extracts.

Background: The use of herbal extracts is becoming more popular as a result of the rise in bacterial resistanceto conventional antibiotics. Plantago major is a commonherbal plant used in conventional medicine. It was well known to have a number of medicinal benefits. Aim: The currentstudy aimed to evaluate the antibacterial activityof aqueous extractof P. major leaves against Pseudomonas aeruginosa isolated from burn infections. Materials and Methods: One hundred and thirty five of P. aeruginosa were collected from hospitalized patients in Emergency hospital in Duhok city. The isolates were identified by routine methods. P. major leaves antibacterial activity were performed by using aqueous extract in serial dilutions with the concentrations of (100, 75, 50, 25, and 10 %) by agar well diffusion assay, also antibiotics susceptibility test were done by the disc diffusion method using Muller-Hinton agar medium. Results: Varied aqueous extractof P. major leaves concentrations showed differentinhibitory zones of P. aeruginosa. The inhibitory zone measured by the efficacy of the aqueous extract of P. major leaves on P. aeruginosa ranges fro m [6.8-16.4] mm in diameter.The zone of inhibition grew as extract concentration increased; P. aeruginosa was most inhibited by an extract conc entration of [100%] ethanolic extract, which exhibited a [16.4 mm] inhibition zone. Additionaly, the bacteria display ed a high level of resistance to the utilized antibiotics. Conclusion: The results of this study show that the replacement of chemical drugs with herbal extract could be effective in the elimination of bacterial growth.
