ESBL + AmpC screen ID

Intended Use

Current susceptibility tests are not accurate enough for surveillance of ESBL and AmpC producing pathogens. Laboratories testing ESBL and AmpC, need to be aware, that some of these organisms may test false positive for ESBL, using CLSI methodology.

  • Simple to test
  • Easy to interpret
  • Long shelflife
  • After opening, room temperature storage (≤ 25°C)
  • High sensitivity and specificity

Combined disk test
Apply one tablet of:
A = Cefotaxime (CEFOTAXIME)
B = Cefotaxime+Clavulanate (CEFOTAXIME+CLAVULANATE)
C = Cefotaxime+Cloxacillin (CEFOTAXIME+CLOXACILLIN)
D = Cefotaxime+Clavulanate+Cloxacillin (CEFOTAXIME+CLAVULANATE+CLOXACILLIN)
on an inoculated Mueller Hinton agar plate (McFarland 0.5).

Interpretation

Neither ESβL nor AmpC: All zones within 2 mm of each other. CTXCC = Cefotaxime + Clavulanate + Cloxacillin Note : “-“ means that the difference is irrelevant for the mechanism (i.e. the difference between CTXCC compared to CTX30 is irrelevant for the detection of ESBL).


In strains possessing both chromosomal (Enterobacter, Cit. freundii etc.) or plasmidic AmpC beta lactamases and ESBLs, Boronic acid or Cloxacillin, are used as inhibitors of the AmpC betalactamase.
