Genomic characterization of vancomycin-resistant enterococci in Norwegian poultry.

PMID 40465609 · 2025

The study identified vanA and narAB genes on pVEF-like plasmids in vancomycin-resistant Enterococcus faecium and E. hirae isolates from Norwegian poultry, along with additional resistance genes such as ermB, tetM, and aac(6')-Ii.

Determination of epidemiological cut-off values for Narasin, Salinomycin, Lasalocid and Monensin in Enterococcus faecium.

PMID 40740068 · 2025

The study determined epidemiological cut-off values (ECOFFs) for narasin, salinomycin, lasalocid, and monensin in Enterococcus faecium. The presence of the narAB genes was associated with resistance to narasin and salinomycin.
