Molecular epidemiology of a multidrug-resistant outbreak in Tunisia (2022-2023) using whole-genome sequencing.

The prevalence of multidrug-resistant (MDR) is increasing globally, raising concerns for public health. In 2022, an outbreak of MDR was observed in Tunisia. We aimed to evaluate the genetic profile of isolates during the outbreak, including their clonal relationship, antimicrobial determinants and connection to international strains.
