Abstract

Abstract : Purpose. : The global spread and increasing clinical impact of carbapenemase‐producing bacteria are alarming. Rapid diagnostic techniques for carbapenemase detection are of the utmost importance to prevent delays in efficient antibiotic therapy and the control of spread in hospitals. Recently, multiplex immunochromatographic lateral flow tests (ICTs) for the fast detection of carbapenemase‐producers have become commercially available. We evaluated a novel multiplex ICT for the rapid detection of OXA‐48, KPC, NDM and VIM carbapenemases. Methodology. : One hundred well‐characterized multidrug‐resistant Enterobacteriaceae were analysed by RESIST‐4 (Coris, BioConcept, Gembloux, Belgium). The reference standard included confirmation at the molecular level at the German National Reference Laboratory for multidrug‐resistant Gram‐negative bacteria (Ruhr‐University Bochum, Germany). Results/Key findings. : The tested ICT was highly reliable, showing 100 % sensitivity and 100 % specificity. Conclusion. : As it is fast, easy to perform and has few technical requirements, the ICT represents a good opportunity to improve turnaround times and patient care for the clinical microbiology laboratory.
