Antimicrobial Resistance and Molecular Characterization of Extended-Spectrum β-Lactamase-Producing Isolated from Ducks in South Korea.

Ducks are potential carriers of pathogenic bacteria, which are capable of transmitting zoonotic diseases to humans. The global spread of carrying extended-spectrum β-lactamase (ESBL) genes is a public health concern. This study investigated the prevalence of antimicrobial resistance in isolated from ducks in Korea and described the molecular characteristics of the ESBLs they produced.

Detection of oxazolidinone and phenicol resistant enterococcal isolates from duck feces and carcasses.

The heavy use or abuse of antimicrobials in food animals has caused an increase in antimicrobial resistance in enterococci of animal origin, which could get transmitted to those of human origin via the food chain. Since duck meat consumption has been on the rise in Korea, we conducted this study to provide information about the antimicrobial resistance of the enterococci obtained from healthy ducks and their carcasses. A total of 82 Enterococcus faecium and 174 E.
