However, a few carbapenem-resistant enterobacterial isolates have been reported; resistance may be caused by production of carbapenemases (2) or by combined mechanisms of an outer membrane permeability defect and extended-spectrum [beta]-lactamases or cephalosporinase (3-6). Possible mechanisms for ceftazidime resistance among gram-negative bacilli are alterations in outer membrane proteins, overproduction of cephalosporinase, or production of an extended-spectrum [beta]-lactamase (ESBL). A synergy image, signature of the presence of an ESBL, could not be observed between clavulanic acid and cefepime or ceftazidime disks on a routine antibiogram (Figure 3A) unless cloxacillin-containing plates that inhibit cephalosporinase activity were used (Figure 3B). |
