Escherichia coli novel sequence type 11873 harbours a new CTX-M-15-carrying multidrug resistance type 1/2 hybrid IncC plasmid.

Objective: The aim of the current study was to determine the genomic map of the resistance genes of two CTX-M-15-carrying Escherichia coli strains belonging to novel sequence type (ST) 11873. Complete, closed genome sequences of the E. coli strains were obtained by applying a combination of short-read Illumina and long-read Oxford Nanopore-based sequencing.

Emergence and dissemination of epidemic-causing OXA-244 carbapenemase-producing Escherichia coli ST38 through hospital sewage in Norway, 2020-2022.

Background: Population-based sewage surveillance has emerged as a promising approach for studying the prevalence of antibiotic resistance in pathogens.

Aim: To determine the temporal prevalence of cefotaxime-resistant Escherichia coli in sewage from five sewage treatment plants located in Bergen city, to determine whether ESBL- and carbapenemase-producing E. coli are consistently disseminated in the receiving environment through sewage.

Tigecycline-resistant Klebsiella pneumoniae strains from sewage in Norway carry heavy-metal resistance genes encoding conjugative plasmids.

Objectives: Tigecycline is a last-resort antibiotic used for treatment of infections with carbapenem-resistant Klebsiella pneumoniae. The aim of the study was to understand the genetic mechanism of resistance and the genetic context of resistance genes in two tigecycline-resistant K. pneumoniae strains isolated from sewage in Bergen, Norway.

Exploring the biosynthetic gene clusters in Brevibacterium: a comparative genomic analysis of diversity and distribution.

Exploring Brevibacterium strains from various ecosystems may lead to the discovery of new antibiotic-producing strains. Brevibacterium sp. H-BE7, a strain isolated from marine sediments from Northern Patagonia, Chile, had its genome sequenced to study the biosynthetic potential to produce novel natural products within the Brevibacterium genus.
