Considering the large number of the multiresistant bacterial strains and the increasing need in new antimicrobial formulation, the aim of this study was to evaluate the antipathogenic effect of E. caryophyllata essential oil on collection and recently isolated clinical strains of P. aeruginosa and S. aureus. Experimental assays were carried out by in vitro and in vivo tests. Qualitative and quantitative assessment of the antimicrobial activity was followed by the analysis of the essential oil influence on enzymatic soluble virulencefactors expression. The cytotoxic effect of the vegetal extract was quantified by usingHeLa cells. Nanosystem embedded essential oil was used to establish the in vivoantipathogenic effect on mice. Qualitative screening results revealed an early microbicidaleffect quantified by low minimum inhibitory concentration values. The in vivo studyshowed a stabiliziation of the essential oil biological activities when using nanosystemembedding, that could be used for the design of proper formulations for delivery systemswith antimicrobial effect.
