The study analyzed 515 E. coli isolates from pigs using whole genome sequencing to identify AMR genes and mutations. Key findings include the prevalence of blaTEM-1b, tet(A), and tetA(B) genes, along with various mutations in gyrA, parC, and parE that confer resistance to fluoroquinolones. The study highlights the effectiveness of WGS in predicting AMR phenotypes with high concordance to MIC results.
