Effect of Rosmarinus officinalis extract on pathogenic bacteria isolated from respiratory tract infection

Abstract

Nowadays, the prevalence of resistant bacteria is a result of the growing usage of antibiotics. The dearth of novel antimicrobial medications with less adverse effects than antibiotics is our problem. In conventional medicine, rosemary is a useful herb with numerous applications. In this research experiment, Rosmarinus officinalis was used to evaluate the antimicrobial effects on pathogens. The antibacterial properties of alcohol and aqueous extract were assessed using the well diffusion method on strains of Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Strepto.agalctiae, The minimum inhibitory concentration (MIC) of the extract on the growth of these bacteria was determined using the microplate method, and it was changed from 25 mg/ml to 100 mg/ml, These results imply that rosemary extract has an inhibiting impact on all strains, including Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, and Strepto. galactic. Additionally, as the concentration was increased, the extract's effect increased.
