In addition to known primary antimicrobial resistance genes and associated regulatory elements, namely oqxAB for CIP20, the arn/pmr operons for CST6 and blaKPC3 for IPM21, we identified 35 non-essential chromosomal genes/operons involved in CST resistance (Table 1), and single chromosomal genes involved in resistance to CIP and IPM (Table 2). Here, CASZ1 is linked to hereditary sensory and autonomic neuropathy.
