Figure 1 AMR patterns of clinically important Aeromonas isolates by sources and species. (A) AMR profiling of clinical Aeromonas isolates from top six specimen sources. (B) AMR profiling of three clinically important Aeromonas species. A. hydrophila: Aeromonas hydrophila complex; A. veronii: Aeromonas veronii complex; A. caviae: Aeromonas caviae complex. Asterisks indicate statistical significance as p values were less than 0.05.

Abbreviations: TZP, piperacillin/tazobactam; CAZ, ceftazidime; CRO, ceftriaxone; FEP, cefepime; ATM, aztreonam; IMP, imipenem; MEM, meropenem; GEN, gentamicin; CIP, ciprofloxacin; LEV, levofloxacin; SXT, trimethoprim-sulfamethoxazole.

(A) A. hydrophila: Aeromonas hydrophila complex; (B) A. caviae: Aeromonas caviae complex; (C) A. veronii: Aeromonas veronii complex.
