Evaluation of the immunochromatographic NG-test Carba5 for rapid identification of carbapenemase in non-fermenters.
2019
The immunochromatographic assay NG-Test Carba 5 (NG-Biotech) was evaluated with a collection of 107 carbapenemase-producing nonfermenters (CP-NF) (55 Pseudomonas spp., 51 Acinetobacter spp., and 1 Achromobacter xylosoxidans isolate) and 61 carbapenemase-negative isolates. All KPC, VIM, and NDM carbapenemase producers tested were accurately detected. Of the 16 IMP variants tested, 6 (37.5%) variants were not detected. Considering the epidemiology of CP-NFs in France, the NG-Test Carba 5 would detect 89.4% of CP Pseudomonas spp. but only 12.9% of CP Acinetobacter spp.
