Implication

Investigation reveals co-selection of antimicrobial resistance genes in Klebsiella pneumoniae and Serratia marcescens isolates, highlighting urgent genomic surveillance needs.

Key Points

Findings indicate the presence of 70 resistance-related genes in clinical isolates from three ICU patients, emphasizing the threat of multidrug-resistant bacteria.
Nineteen identified plasmids contained critical genes including blaKPC-2, suggesting significant antimicrobial resistance mechanisms in play during the COVID-19 outbreak.
Whole-genome sequencing revealed distinct gene clusters indicating co-localization of resistance genes, pointing to a worrying trend in antibiotic resistance.
Genomic surveillance is critical in resource-limited healthcare settings to combat the rise of antimicrobial resistance exacerbated by the COVID-19 pandemic.
