a Tobramycin-resistant E. coli (DA69068-70), b tetracycline-resistant S. Typhimurium (DA69071-73), c cefepime-resistant S. Typhimurium (DA69074-76), and d piperacillin-tazobactam resistant E. coli (DA69077-79). For each antibiotic and strain, three independent clones were examined (see Table 1). Determination of copy numbers was based on 1 biological and 1 technical replicates (n = 1).
