The colonisation of Czech travellers and expatriates living in the Czech Republic by colistin-resistant Enterobacteriaceae and whole genome characterisation of E. coli isolates harbouring the mcr-1 genes on a plasmid or chromosome: A cross-sectional study

Popis výsledku v původním jazyce

Background: Travellers were recognized as risk cohort that can be colonized by mcr-1-mediated colistin resistant Enterobacteriaceae. We aimed to investigate the carriage of mcr-mediated colistin resistance in Enterobacteriaceae in Czech travellers or expatriates residing temporarily in the Czech Republic. Methods: Between August 2018 and September 2019, the stool samples were cultured in Enterobacteriaceae enrichment broth. The enriched cultures were tested for the presence of mcr-1-8 genes and inoculated onto selective agar with colistin. A minimal inhibitory concentration of colistin was determined by using the broth microdilution method. Colistin resistant Enterobacteriaceae isolates were tested for the presence of mcr-1-8 genes and mcr-positive isolates were characterised by whole genome sequencing. Results: From 177 stool samples, 15 Enterobacteriaceae isolates were cultured (7.9%); two E. coli isolates carried mcr-1 gene (1.1%). In E. coli sequence type (ST) 156, the mcr-1 gene was located in an ISApl1-mcr-1-orf-ISApl1 (Tn6330) and incorporated into the chromosome; in E. coli ST23 isolate, the mcr-1 gene was harboured by the plasmid IncX4. Both, mcr-1 positive E. coli were multidrug resistant and, in addition, one isolate was an extended-spectrum β-lactamase (ESBL) producer (blaCTX-M-27). Conclusion: Czech travellers, or expatriates in the Czech Republic, can be colonized by multidrug resistant Enterobacteriaceae harbouring the mcr-1 gene.
