Abstract:
Vegetal compounds are known for their therapeutic actions in correlation with their antioxidant activity so that in recent
times the interest in their properties has greatly increased.
The phytocomplex obtained by combining the Zingiber officinale extract, Piper nigrum and Piper cubeba oil is
distributed and recommended in European space as a multi-benefit nutritional supplement for swine, poultry, cattle,
horses and others. As the individual properties of the three compounds are known, we aimed to test the antimicrobial
activity of the phytocomplex on various Gram negative pathogens.
In the time-kill assay, in vitro inhibitory effects were visible after 15 minutes of contact and total inhibition of the
species Samonella enteritidis, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa was obtained after 24
hours.
The results obtained in vitro showed a very good antimicrobial activity which clearly contributes to the overall
beneficial effects of the Zingiber officinale extract, Piper nigrum and Piper cubeba oil phytocomplex.
