Discovery of a novel integron-borne aminoglycoside resistance gene present in clinical pathogens by screening environmental bacterial communities
Böhm, Maria-Elisabeth; Razavi, Mohammad; Marathe, Nachiket; Flach, Carl-Fredrik; Larsson, D. G. Joakim (Peer reviewed; Journal article, 2020)Background New antibiotic resistance determinants are generally discovered too late, long after they have irreversibly emerged in pathogens and spread widely. Early discovery of resistance genes, before or soon after their ... -
Genomic characterization of multidrug-resistant Bacillus toyonensis strain 4HC1 isolated from marine plastic in Norway
Radisic, Vera; Marathe, Nachiket (Peer reviewed; Journal article, 2021)Bacillus toyonensis is widespread in nature.

Identification and reconstruction of novel antibiotic resistance genes from metagenomes
Berglund, Fanny; Osterlund, Tobias; Boulund, Fredrik; Marathe, Nachiket; Larsson, D.G. Joakim; Kristiansson, Erik (Journal article; Peer reviewed, 2019)Background Environmental and commensal bacteria maintain a diverse and largely unknown collection of antibiotic resistance genes (ARGs) that, over time, may be mobilized and transferred to pathogens. Metagenomics enables ... -
Knockout of Targeted Plasmid-Borne β-Lactamase Genes in an Extended-Spectrum-β-Lactamase-Producing Escherichia coli Strain: Impact on Resistance and Proteomic Profile
Jaén-Luchoro, Daniel; Karlsson, Roger; Busquets, Antonio; Iglesias, Beatriz Piñeiro; Karami, Nahid; Marathe, Nachiket; Moore, Edward RB (Peer reviewed; Journal article, 2023)Resistance to β-lactams is known to be multifactorial, although the underlying mechanisms are not well established. The aim of our study was to develop a system for assessing the phenotypic and proteomic responses of ... -
Long-term investigation of the ‘soft flesh’ condition in Northeast Atlantic mackerel induced by the myxosporean parasite Kudoa thyrsites (Cnidaria, Myxozoa): Temporal trends and new molecular epidemiological observations
Giulietti, Lucilla; Karlsbakk, Egil Erlingsson; Cipriani, Paolo; Bao Dominguez, Miguel; Storesund, Julia Endresen; Marathe, Nachiket; Levsen, Arne (Peer reviewed; Journal article, 2022)Northeast Atlantic (NEA) mackerel (Scomber scombrus, Scombridae) represents an economically important target for the Norwegian pelagic fishing industry. Despite the commercial significance of NEA mackerel, little is known ... -
Marine plastics from Norwegian west coast carry potentially virulent fish pathogens and opportunistic human pathogens harboring new variants of antibiotic resistance genes
Radisic, Vera; Nimje, Priyank Sharad; Bienfait, André Marcel; Marathe, Nachiket (Peer reviewed; Journal article, 2020)To our best knowledge this is the first study characterizing fish pathogens isolated from marine plastics from the West coast of Norway for their potential for pathogenicity using whole genome sequencing.
