Abstract
Objective: To characterise four blaNDM-5-harbouring plasmids recovered in Enterobacterales isolated in Argentina.
Methods: DNA was sequenced by Illumina and Oxford Nanopore technologies, assembled using Unicycler, analysed using PlasmidFinder, MOB-Typer, IslandViewer4 and Resfinder, and visualised by Proksee and Clinker. blaNDM-5-harbouring plasmids were compared with deposited similar ones using PLSDB.
Results: two plasmids belonged to incompatibility group IncFII where blaNDM-5 was located in a previously described genetic context, immersed in an antimicrobial resistance island (ARI). Local IncFII plasmids displayed high similarity (≥ 90% shared hashes (sh)) with four deposited in PLSDB. The other two local plasmids belonged to the multi-replicon group IncFIB-HI1B, harbouring blaNDM-5 in a novel variant of the genetic context. Both multi-replicon plasmids, presented two ARI, one containing blaNDM-5 in addition to other ARM; and the second ARI carrying blaCTX-M-15 and a class 1 integron. Plasmids deposited in PLSDB showed low similarity to local multi-replicon plasmids. The most similar plasmids (n:5) displayed less than 60% sh showing the same Inc groups but lacking ARM.
Conclusion: This study broadens the limited understanding of blaNDM-5-harbouring plasmids in Latin America. Furthermore, it represents the first description of blaNDM-5 in a novel variant of the common genetic platform and its location in multi-replicon IncFIB-IncHI1B plasmids, which were not previously associated with any antimicrobial resistance marker (ARM).
期刊介绍:
The Journal of Global Antimicrobial Resistance (JGAR) is a quarterly online journal run by an international Editorial Board that focuses on the global spread of antibiotic-resistant microbes.
JGAR is a dedicated journal for all professionals working in research, health care, the environment and animal infection control, aiming to track the resistance threat worldwide and provides a single voice devoted to antimicrobial resistance (AMR).
Featuring peer-reviewed and up to date research articles, reviews, short notes and hot topics JGAR covers the key topics related to antibacterial, antiviral, antifungal and antiparasitic resistance.
