NanoMLST: A High‐Throughput Bacterial Multi‐Locus Sequence Typing Workflow Using Oxford Nanopore Next‐Generation Sequencing for ESKAPE + E Pathogens

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
NanoMLST is a workflow suggested as a viable alternative to high‐throughput ST determination for ESKAPE + E pathogens using ONT next‐generation sequencing. ABSTRACT Multi‐Locus Sequence Typing (MLST) is a key method for allocation of Sequence Types (STs) for bacterial isolates. Traditionally, this is performed by the Sanger sequencing method, which can

Detection of blaNDM‐1 and blaIMP‐1 Metallo‐β‐Lactamases in Meropenem‐Resistant Clinical Escherichia coli Isolates Using Modified Carbapenem Inactivation Method (mCIM) and PCR Techniques

Journal of Clinical Laboratory Analysis, Volume 39, Issue 21, November 2025.
This study examines the prevalence of blaNDM‐1 and blaIMP‐1 metallo‐β‐lactamase genes in meropenem‐resistant Escherichia coli isolates using mCIM and PCR. The results indicate a higher prevalence of blaNDM‐1 and suggest the presence of alternative resistance mechanisms in some strains, emphasizing the need for further research on antimicrobial ...
