Detection of Virulence Genes in Multidrug Resistant Enterococci Isolated from Feedlots Dairy and Beef Cattle: Implications for Human Health and Food Safety

BioMed Research International, 2019
The misuse/abuse of antibiotics in intensive animal rearing and communities led to the emergence of resistant isolates such as vancomycin-resistant enterococci (VREs) worldwide. This has become a major source of concern for the public health sector.

Copaiba oleoresin as a substitute for sodium lasalocid in high‐concentrate diets for lambs: growth performance, ingestive behavior, and metabolic and ruminal parameters

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The indiscriminate and excessive use of ionophore additives has been associated with the emergence of multi‐resistant pathogenic strains and the global spread of antibiotic resistance, raising serious public health concerns. Thus, plant biocompounds have been the focus of several studies aiming to replace ionophore additives in ...
