RESUMO
A 2-year national genomic screening in the Czech Republic identified a notable prevalence of the New Delhi metallo-ß-lactamase 5 (NDM-5)-producing Escherichia coli sequence type 38 (ST38) in the city of Brno. Forty-two ST38 E. coli isolates harbored the blaNDM-5 gene on the chromosome. Virulence factors confirmed the persistence of these isolates through biofilm formation. Single Nucleotide Polymorphisms (SNPs)-based phylogeny and CRISPR assay typing showed minimal genomic variations, implying a clonally driven outbreak. Results suggest that this high-risk clone may impose a nationwide problem.
