Abstract


Treatment failures and the more high cost of treatment of infections caused by resistant bacteria called to find other care alternatives. This study was initiated to evaluate the antibacterial activity of the aqueous extract from Hunteria ebunea stem bark on multi-resistant strains. The methods of diffusion in agar and liquid media were used for susceptibility testing and MIC and MBC determination. The tests were performed on four multi-resistant strains isolated from patients and three reference strains were used as control. The minimum inhibitory concentrations of the extracts ranged from 3,12 mg/mL and 50 mg/mL and minimum bactericidal concentrations between 25 mg/mL and 100 mg/mL. The results obtained show that all the bacterial strains are sensitive to aqueous total extract. This extract is bactericidal on S. aureus, E. coli and bacteriostatic on P. aeruginosa. This migth justify the use of Hunteria eburnea trunk back in the treatment of various infections in traditional settings.

Author Keywords: Hunteria eburnea, aqueous extract, MIC, MBC, Ivory Cost.


Abstract: (french)


Les coûts de plus en plus élevés des traitements des infections dues aux bactéries résistantes appellent à trouver d’autres alternatives de soins. La présente étude a été initiée dans le but d’évaluer l’activité antibactérienne de l’extrait aqueux de l’écorce de tronc de Hunteria eburnea sur des souches multi-résistantes. Les méthodes de la diffusion en milieu gélosé et en milieu liquide ont été utilisées pour le test de sensibilité et la détermination de la CMI et de la CMB. Les différents tests ont été effectués sur quatre souches multi-résistantes isolées chez des malades et trois souches de référence. Les concentrations minimales inhibitrices des extraits varient entre 3,12 mg/ml et 50 mg/ml et les concentrations minimales bactéricides entre 25 mg/mL et 100 mg/ml. Les résultats obtenus montrent que toutes les souches bactériennes sont sensibles à l’extrait total aqueux. Cet extrait est bactéricide sur S.aureus, E.coli et bactériostatique sur P.aeruginosa. Ceci pourrait justifier l’utilisation de l’écorce de tronc de Hunteria eburnea dans le traitement de diverses infections en milieux traditionnels.
