摘要：
The optimal method for surveillance of carbapenem-resistant Acinetobacter spp. (CRAB) is unknown. A collection of CRAB strains (n = 42), carbapenem-susceptible strains (CSAB), and non-Acinetobacter strains (n = 18) was used to evaluate six laboratory surveillance methods: MacConkey (MAC), MAC + 1 mu g/ml imipenem (MAC-IPM), minimal salts agar + 1 % acetate (MSA), MSA with IPM disk (MSA-IPM), CHROMagarKPC, and CHROMagar Acinetobacter with CR102 (CHROMAcineto). CHROMAcineto was 100 % sensitive and specific. CHROMagarKPC and MAC-IPM were highly sensitive (> 95 %), but their specificity was substantially hampered by the breakthrough growth of CSAB. MSA was unsuitable for CRAB detection. CHROMAcineto is a promising medium for CRAB detection and warrants further clinical evaluation.
