Introduction Currently, the emergence of bacterial resistance poses a significant challenge to public health worldwide. With the widespread use of antimicrobial agents in recent years, the isolation of multidrug-resistant Escherichia coli has increased yearly, particularly among Extended Spectrum β-lactamases (ESBLs) producing strains, which can cause not only multi-site infections but…

Three samples of S. 4,[5],12:i:-, all isolated in 2010, harbored mcr-3.1. Two were from human stool and the other was from ready-to-eat frozen food. Phenotypic characterization confirmed that all three isolates were resistant to colistin, all with MIC and MBC of 8 µg/ml. WGS of H1-012, H1-014 and H1-120 were analyzed…

Bacterial isolate Adolfo Lutz Institute is a regional reference laboratory for Salmonella isolates from São Paulo, Brazil. Thus, all isolates received are submitted to classical serotyping, antimicrobial susceptibility testing, and molecular-typing by PFGE and next-generation sequencing. Isolate 288_18 was recovered from a blood sample from a patient with clinical symptoms…

Antimicrobial susceptibility data of S. sonnei in France Our review of S. sonnei antimicrobial susceptibility data obtained between 2005 and 2021 (based on 7121 isolates received and confirmed at the French National Reference Center for E. coli, Shigella and Salmonella, FNRC-ESS, Institut Pasteur) revealed a sharp increase in the percentage…

Sample dataset description To reconstruct the phylogeny of S. Enteritidis human isolates in a global context, 159 genomes of S. Enteritidis from different countries were selected and downloaded from our initial query of public data in addition to the 16 S. Enteritidis genomes our laboratory sequenced in the study. In…

Introduction Escherichia coli is a common Gram-negative opportunistic pathogen that causes invasive host infections through virulence factors such as flagella, toxin secretion, and adhesins. According to the source of the infection, pathogenic E. coli can be classified as intestinal (diarrheagenic) and extraintestinal (ExPEC). Uropathogenic E. coli (UPEC) is the most…

Introduction Klebsiella pneumoniae (K. pneumoniae) is an opportunistic pathogen and the leading cause of healthcare-associated infections.1 Multidrug-resistant (MDR) K. pneumoniae isolates are rapidly spreading, thus limiting the choice of antimicrobial agents for empiric treatment of infections caused by these microorganisms; hence, this is a public health challenge.2 Polymyxins are last-resort…
