The study identified several AMR genes in Citrobacter freundii isolates, including bla TEM−1, bla CTX−M−9, aac(6')-Ib-cr, qnrS1, and various qnrB alleles such as qnrB9, qnrB13, qnrB16, qnrB17, qnrB76, qnrB77, and a newly discovered qnrB92. These genes were associated with resistance to multiple antibiotics, including beta-lactams, aminoglycosides, and quinolones.
