Zusammenfassung:Objective To analyze the clinical characteristics of intestinal infection caused by Aeromonas and their drug susceptibility. Methods The data of 52 patients infected with Aeromonas were analyzed retrospectively. Aeromonas strains were identified with Vitek II Compact. Drug susceptibility was determined by disk diffusion methods. Cefoxitin combined with ceftazidime, aztreonam, cefotaxime and ceftriaxone were used to detect inducible expression of AmpC beta -lactamase. Results Abdominal pain, watery diarrhea, tenesmus occurred in 75.0%, 48.1%, and 38.0% of the patients, respectively. White blood cell tests were positive in 50.0% patients' stools. 52 strains of Aeromonas were isolated, including 38 strains of Aeromonas hydrophila, 13 strains of Aeromonas sobria, and 1 strain of Aeromonas veronii. All strains were sensitive to carbapenems, the second, third generation of cephalosporins, monobactam, fluoroquinolone, aminoglycosides. The susceptibility rates to chloramphenicol, trimethoprim-sulfamethoxazole, cefoxi
