摘要: Ce travail vise l’etude de l’activite antibacterienne l’huile essentielle (HE) Pelargoniumx asperum et la bacteriocine, nisine seul en combinaison vis-a-vis six bacteries dont quatre sont multiresistantes d’origine clinique. L’activite in vitro a ete evaluee par methode diffusion sur gelose. La concentration minimale inhibitrice (CMI) est aussi determinee pour HE. Les resultats ont revele une activite significative exercee HE Staphylococcus aureus (ATCC 43300), Escherichia coli avec des diametres d’inhibition 36,00 ; 22,50 40,00 mm, respectivement. Cependant, l’HE Pelargonium montre superieure rapport nisine. valeurs CMI rapportees dans cette etude comprises entre 1,98–3,96 μl/ml. combinaisons realisees un effet additif 25922) (50 % + 50 nisine). Par contre, nous avons enregistre synergie Klebsiella pneumoniae (75 25 nisine) contre Pseudomonas aeruginosa les trois testees. obtenus permettent dire que possede ainsi sa pourrait representer bonne alternative lutte l’antibioresistance.
