Genetic Plurality of OXA/NDM-Encoding Features Characterized From Enterobacterales Recovered From Czech Hospitals

Original language description

The aim of this study was to characterize four Enterobacterales co-producing NDM- and OXA-48-like carbapenemases from Czech patients with travel history or/and previous hospitalization abroad. Klebsiella pneumoniae isolates belonged to &quot;high risk&quot; clones ST147, ST11, and ST15, while the Escherichia coli isolate was assigned to ST167. All isolates expressed resistance against most beta-lactams, including carbapenems, while retaining susceptibility to colistin. Furthermore, analysis of WGS data showed that all four isolates co-produced OXA-48- and NDM-type carbapenemases, in different combinations (Kpn47733: bla(NDM-)(5) + bla(OXA-)(181); Kpn50595: bla(NDM-)(1) + bla(OXA-)(181); Kpn51015: bla(NDM-)(1) + bla(OXA-)(244); Eco52418: bla(NDM-)(5) + bla(OXA-)(244)). In Kpn51015, the bla(OXA-)(244) was found on plasmid p51015_OXA-244, while the respective gene was localized in the chromosomal contig of E. coli Eco52418. On the other hand, bla(OXA-)(181) was identified on a ColKP3 plasmid in isolate Kpn47733, while a bla(OXA-)(181)-carrying plasmid being an IncX3-ColKP3 fusion was identified in Kpn50595. The bla(NDM-)(1) gene was found on two different plasmids, p51015_NDM-1 belonging to a novel IncH plasmid group and p51015_NDM-1 being an IncF(K)(1)-FIB replicon. Furthermore, the bla(NDM-)(5) was found in two IncFII plasmids exhibiting limited nucleotide similarity to each other. In both plasmids, the genetic environment of bla(NDM-)(5) was identical. Finally, in all four carbapenemase-producing isolates, a diverse number of additional replicons, some of these associated with important resistance determinants, like bla(CTX-M-)(15), arr-2 and ermB, were identified. In conclusion, this study reports the first description of OXA-244-producing Enterobacterales isolated from Czech hospitals. Additionally, our findings indicated the genetic plurality involved in the acquisition and dissemination of determinants encoding OXA/NDM carbapenemases.
