Title

The Antibacterial Effects of Plantago Minor, Calendula Officinalis and Eucalyptus Polycarpa Extracts Againts Mycobacterium Tuberculosis Invitro

English Abstract

Bacgraound and Objectives: Despite the availability of effective anti tubercle chemotherapy for more than 50 years and major advances in the biology of Mycobacterium tuberculosis, tuberculosis remains the leading cause of adult mortality attributable to a single pathogen. Nowadays, one of the basic problems of tuberculosis treatment is drug resistance. This study was done determine the antibacterial effects of the watery and ethanolic extracts include; Plantago minor, Calendula officinalis and Eucalyptus polycarpa as a natural and herbal antimicrobial substances againts Mycobacterium tuberculosis invitro by assessing minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). Methods: Microorganisms; we used of standard strains of Mycobacterium tuberculosis (C: ATCC 35808 and H37RV : ATCC 25618) and clinical isolates of Mycobacterium tuberculosis that obtained from thetuberculosis patients, These strains were identified as Mycobacterium tuberculosis complex by PCR targeting the insertion sequence IS6110. In this experiment –clinical trail, cold maceration methods by ethanol (70%) and water was use for extraction of Calendula officinalis flowers and Plantago minor leaves and Eucalyptus polycarpa leaves. We used of serial dilution in tube methods in Middlebrook 7H9 Broth for evaluation (MIC) of the extracts. Then we used of Lowenstein– Jensen (LJ) medium supplemented with pyruvate for evaluation (MBC) of the extracts. Resuls: In this study we observed MIC of watery(W) and ethanolic(E) extracts of Plantago minor : 3.9 µg/ml (W), 15.7 µg/ml (E), Calendula officinalis: 125 µg/ml(W), 3.9 µg/ml (E) and Eucalyptus polycarpa: 31.2 µg/ml (W), 125 µg/ml (E) respectively, and results of MBC included; Plantago minor 3.9 µg/ml (W), 31.2 µg/ml and Calendula officinalis: 250 µg/ml (W), 7.8 µg/ml (E) and Eucalyptus polycarpa 125 µg/ml (W), 250 µg/ml (E) respectively. Conclusion: We observed the best antibacterial effects againts Mycobacterium tuberculosis about watery extract of Plantago minor and Ethanolic extract of Calendula officinalis, it seems these extracts Can be use as antibacterial agents against multiple drug resistance tuberculosis cases (MDR-TB).
