Reliable direct identification was obtained in 14 of the 27 (51.8%) urinary source bacteraemias. There was 100% agreement between the lateral flow and antibiogram in the detection of ESBL and carbapenemases.the protocol for the direct identification and rapid detection of ESBL and carbapenemases-producing strains from urine samples is a reliable and useful tool.6 p.application/pdfengcc by (c) Zboromyrska, Yuliya et al, 2022http://creativecommons.org/licenses/by/3.0/es/Infeccions del tracte urinariBacteris patògensUrinary tract infectionsPathogenic bacteriainfo:eu-repo/semantics/article2023-05-02info:eu-repo/semantics/openAccess931528035625226
