Key Findings

The study identified several AMR genes and mutations in Salmonella enterica isolates from the broiler supply chain in Zimbabwe, including fosA7.2, qnrB19, aadA1, aph(3'')-Ib, aph(6)-Id, aac(3)-Id, fosA3, sul1, sul3, tetA, cmlA1, blaCMY-2, blaTEM-1B, blaCTX-M-14, and mutations in gyrA and parC. These genes and mutations confer resistance to various antibiotics, including fosfomycin, fluoroquinolones, aminoglycosides, sulfonamides, tetracyclines, chloramphenicol, and beta-lactams.
