Molecular Characterization of Producing Extended-Spectrum ß-Lactamase and MCR-1 from Sick Pigs in a Greek Slaughterhouse.

The first prospective surveillance of ESBL and colistin-resistant recovered from sick pigs from a slaughterhouse in Central Greece aimed to investigate the spread of relevant genetic elements. In February 2021, 25 isolates were subjected to antimicrobial susceptibility testing using disk diffusion and broth microdilution techniques. PCR screening was conducted to identify ESBLs and genes.
