Article Abstract

Whole plasmid sequencing (WPS) using Nanopore long read sequencing has emerged as a cost-effective alternative for dideoxy sequencing methods. De novo sequence assembly for large plasmids, however, are not always successful and may produce large assembly gaps. Here we streamlined a reference-guided alignment of WPS nanopore reads using galaxy platform. The process is straightforward and facilitate introduction of WPS as an alternative for researchers who are more used to dideoxy sequencing platform. We demonstrate that our procedure can assemble nanopore sequence reads with different quality datasets and identify variations from reference sequence.

Plasmids facilitate antimicrobial resistance (AMR) gene spread via horizontal gene transfer, yet the mobility of genes in wastewater treatment plant (WWTP) resistomes remains unclear. We sequenced 173 circularised plasmids transferred from WWTP effluent into Escherichia coli and characterised their genetic content. Multiple multidrug-resistant plasmids were identified, with a significant number of mega-plasmids (>100 kb).

Plasmids are fundamental to molecular biology and biotechnology, playing a crucial role in bacterial evolution. Some plasmids are linked to complex cellular dynamics, including pathogenicity islands, antibiotic resistance, and gene mobilization. This study reports the isolation and sequencing of two cryptic plasmids with different electrophoretic mobilities from the Escherichia coli clinical isolate O55.

The genomes of 43 distinct lactococcal strains were reconstructed by a combination of long- and short-read sequencing, resolving the plasmid complement and methylome of these strains. The genomes comprised 43 chromosomes of approximately 2.5 Mb each and 269 plasmids ranging from 2 to 211 kb (at an average occurrence of 6 per strain).

Listeria monocytogenes is pervasive in agricultural environments and difficult to eradicate from food-processing facilities. Consequently, various foods become contaminated, posing health risks to immunocompromised individuals. This surveillance study aimed to enhance the understanding of the genetic diversity, virulence, plasmid content, sanitizer tolerance, and antibiotic resistance of L.

Aim: To investigate the phenotypic and genomic features of three multidrug-resistant (MDR) clinical mucoid and non-mucoid uropathogenic Escherichia coli (UPEC) strains to understand their antimicrobial resistance, biofilm formation, and virulence in urinary tract infections (UTIs).

Methods And Results: The UPEC strains A5, A10, and A15 were isolated from two UTI patients. Phenotypic assays included colony morphology, antibiotic susceptibility, motility, and biofilm formation.
