The paper describes the within-host succession of carbapenemase types in E. coli isolates from a single patient, showing a shift from OXA-48-like to NDM-type resistance due to plasmid displacement.

This study identifies a novel hypervirulent extensively drug-resistant ST383 K. pneumoniae lineage in Lebanon carrying ICEKp5 and multiple resistance genes.

The paper uses whole-genome sequencing to analyze Mycobacterium tuberculosis complex isolates from Lebanon, identifying M. tuberculosis lineages and M. bovis clades.

This study identifies genetic and structural mechanisms of colistin resistance in Klebsiella pneumoniae, showing mutations and insertion sequences disrupt lipid A modification and regulatory networks.

This study characterizes multi-drug resistant Enterobacter and Klebsiella aerogenes isolates from Lebanon using whole-genome sequencing, identifying resistance mechanisms and plasmid profiles.

The paper analyzes non-synonymous mutations and polyproline regions in ORF3a of SARS-CoV-2 genomes to assess their impact on B-cell epitope formation and immune evasion.
