• Rapid detection of OXA-48-like, KPC, NDM, and VIM carbapenemases in Enterobacterales by a new multiplex immunochromatographic test.

Abstract
The rapid detection of carbapenemase-producing Gram-negative bacteria is indispensable to optimize treatment and avoid the further spread of these organisms. While phenotypic tests are time-consuming and PCR is expensive and not available in many routine laboratories, immunochromatographic tests (ICT) can provide rapid results at moderate cost. The aim of this study was to determine the performance of the new ICT RESIST-4 O.K.N.V. K-SeT (Coris BioConcept, Gembloux, Belgium) which can detect the four most prevalent carbapenemases: OXA-48-like, KPC, NDM, and VIM. Additionally, we analyzed the impact of different culture conditions on the sensitivity. The new ICT was challenged with 169 carbapenem-resistant isolates. Of these, 125 were carbapenemase producers: 43 OXA-48-like, 15 KPC, 29 NDM, and 43 VIM. The ICT correctly detected 129 of the 130 carbapenemases resulting in a sensitivity of 99.2% and specificity of 100% when tested from Mueller-Hinton agar (MHA). The sensitivity of the assay increased to 100% when performed from zinc-supplemented MHA and sheep blood agar (SBA) or when the inoculum was harvested from the inhibition zone of an ertapenem disk. All carbapenemase-negative carbapenem-resistant bacteria tested negative and no cross-reaction was observed. The new ICT is an excellent test for rapid diagnostic of carbapenemase-producing Gram-negatives in the routine laboratory. It is easy to handle and provides rapid results with a high sensitivity. For best results, we recommend to obtain the inoculum from a medium with sufficient zinc or from the inhibition zone of an ertapenem disk.

• Detection of carbapenemases-producing Enterobacteriaceae in positive blood culture using Immunochromatographic RESIST-4 O.K.N.V assay.

Cointe A, Bonacorsi S, Truong J, Hobson C, Doit C, Monjault A, Bidet P, Birgy A.

Antimicrob Agents Chemother. 2018 Sep 24. pii: AAC.01828-18. doi: 10.1128/AAC.01828-18.

Abstract
We evaluated the performances of the RESIST-4.O.K.N.V assay (Coris®) on 98 isolates to detect OXA-48-like, KPC-, NDM- and VIM-type carbapenemases directly on positive human blood cultures. OXA-48-like and KPC-type isolates were correctly detected but detection of NDM and VIM-type was weak and variable. We show that repeating the test on a 4-hour subculture improves the detection of NDM- and VIM-type to 100%.
