Methods: We collected 121 of clinical isolates of Enterobacter, including 87 isolates Enterobacter cloacae, 34 isolates Enterobacter aerogenes, all of the isolates were detected by cefoxitin three-dimension test, drug resistance phenotypes estimation, cloxacillin disc synergy test and cloxacillin-potentiated disc diffusion test respectively to find high-level AmpC β-lactamase isolates, drug resistance phenotypes estimation were also used to detected high induction producing AmpC β-lactamases isolates, meanwhile, we took three-dimension test as standard method, and compared to other methods, then calculated the coincidence rates, sensitivities and specificities of them.
