ANTIBACTERIAL ACTIVITY OF GOLDEN BERRY (PHYSALIS PERUVIANA) EXTRACT AGAINST ESCHERICHIA COLISPP. ISOLATES FROM MEATS IN ECUADOR
Keywords:Antibacterial activity, Goldenberry extracts, E coli, Meats
Objective: The resistance of pathogenic bacteria to multiple antimicrobials has become a real global threat in terms of food safety and public health. To Study of antibacterial activity of golden berry extracts against E. coli isolated from meats in Ecuador.
Methods: Two solvents (water and ethyl alcohol) were used as well as three parts of the Goldenberry (mature berries, semi-mature berries and leaves) for its transformation into extracts. The extracts obtained were used in tests of anti-E. coli activity, contrasting with Ampicillin and gentamicin by means of the disk difusión method.
Results: Extracts in ethyl alcohol from semi-ripe berries and leaves were more effective at inhibiting the development of E. coli, with A2B1 and A2B3 treatments being those with the best antibacterial effect with 35.3% and 50% respectively. These results were close to those obtained with the antibiotics under study.
Conclusion: The use of uvilla extracts could be a viable natural alternative to act against pathogens.
