Phenotypic and genomic characterization of linezolid non-susceptibility in poultry-derived multidrug-resistant Enterococcus spp. from Hungary
Ákos Jerzsele
BackgroundLinezolid is a critically important oxazolidinone in human medicine, and the emergence of linezolid non-susceptibility in food-animal–associated enterococci raises One Health concerns across the food chain, animal reservoirs, and environmental circulation.MethodsWe analyzed poultry-derived Enterococcus spp. from healthy broiler chicken and turkey farms across seven Hungarian regions. From a total collection of 969 isolates, a resistance-enriched analytical subset (n = 218) underwent br
