Abstract
Massive use of antibiotics in breeding farm has contributed to the spread of multidrug resistant bacteria and poultry has been suggested as a reservoir for multidrug -resistant Escherichia coli strains. Many plant derived essential oils (EOs) exhibit biological activitymainly due to typical features of their components such as hydrophobicity, that allows partitioning with the lipids of the bacterial cell membrane interfering with the cell permeability and resulting in a bactericidal/bacteriostatic effect. Nanoemulsions (NEs) are colloidal dispersion in which main components are oil, emulsifying agents and aqueous phases. NEs were investigated to improving the delivery of active pharmaceutical or natural ingredients. In order to test the inhibiting activity on bacterial growth and biofilm production, NEs obtained from S. Montana essential oil has been tested against E. coli isolates from healthy poultry fecal samples characterized for antibiotic resistance and metal tolerance.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
