Metoder for påvisning av Listeria i mat og produksjonsmiljø – Faglig sluttrapport
Moen, Birgitte; Langsrud, Solveig; Fagerlund, Annette (Nofima rapportserie, Research report, 2024)Dagens referansemetode for påvisning av Listeria monocytogenes tar minimum to dager før man får et endelig svar. Dette reduserer mulighetene for å gjøre risikoreduserende tiltak. Prosjektet har kartlagt dagens kommersielle ... -
Microbial diversity and ecology of biofilms in food industry environments associated with Listeria monocytogenes persistence
Fagerlund, Annette; Langsrud, Solveig; Møretrø, Trond (Peer reviewed; Journal article, 2021)Contamination of food products with the foodborne pathogen Listeria monocytogenes may occur in the food processing environment. Many bacterial species co-exist in this environment and can interact in multispecies biofilms. ... -
MogR is a ubiquitous transcriptional repressor affecting motility, biofilm formation and virulence in Bacillus thuringiensis
Smith, Veronika; Josefsen, Malin; Lindbäck, Toril; Hegna, Ida Kristin; Finke, Sarah; Tourasse, Nicolas Jacques; Nielsen-LeRoux, Christina; Økstad, Ole Andreas; Fagerlund, Annette (Peer reviewed; Journal article, 2020)Flagellar motility is considered an important virulence factor in different pathogenic bacteria. In Listeria monocytogenes the transcriptional repressor MogR regulates motility in a temperature-dependent manner, directly ... -
Pervasive Listeria monocytogenes Is Common in the Norwegian Food System and Is Associated with Increased Prevalence of Stress Survival and Resistance Determinants
Fagerlund, Annette; Wagner, Eva; Møretrø, Trond; Heir, Even; Moen, Birgitte; Rychli, Kathrin; Langsrud, Solveig (Peer reviewed; Journal article, 2022)To investigate the diversity, distribution, persistence, and prevalence of stress survival and resistance genes of Listeria monocytogenes clones dominating in food processing environments in Norway, genome sequences from ... -
Surveillance of Listeria monocytogenes: Early detection, population dynamics and quasimetagenomic sequencing during selective enrichment
Wagner, Eva; Fagerlund, Annette; Langsrud, Solveig; Møretrø, Trond; Jensen, Merete Rusås; Moen, Birgitte (Peer reviewed; Journal article, 2021)In this study, we addressed different aspects regarding the implementation of quasimetagenomic sequencing as a hybrid surveillance method in combination with enrichment for early detection of Listeria monocytogenes in the ... -
The putative drug efflux systems of the Bacillus cereus group
Hassan, Karl A.; Fagerlund, Annette; Elbourne, Liam D.H.; Vörös, Aniko; Kroeger, Jasmin Kaori; Simm, Roger; Tourasse, Nicolas Jacques; Finke, Sarah; Henderson, Peter J.F.; Økstad, Ole Andreas Løchen; Paulsen, Ian T.; Kolstø, Anne-Brit (Peer reviewed; Journal article, 2017) -
Tolerance to quaternary ammonium compound disinfectants may enhance growth of Listeria monocytogenes in the food industry
Møretrø, Trond; Schirmer, Bjørn Christian; Heir, Even; Fagerlund, Annette; Hjemli, Pernille; Langsrud, Solveig (Journal article, 2016)The antibacterial effect of disinfectants is crucial for the control of Listeria monocytogenes in food processing environments. Tolerance of L. monocytogenes to sublethal levels of disinfectants based on quaternary ammonium ... -

Langsrud, Solveig; Fagerlund, Annette; Moen, Birgitte; Møretrø, Trond; Heir, Even (Research report, 2024)Denne veilederen er utarbeidet av forskerne Solveig Langsrud, Annette Fagerlund, Trond Møretrø, Even Heir og Birgitte i Moen i prosjektet PathoSeq og er basert på både praktisk kunnskap og forskning. Det er matprodusenter ... -
Whole room disinfection with hydrogen peroxide mist to control Listeria monocytogenes in food industry related environments
Møretrø, Trond; Fanebust, Helge; Fagerlund, Annette; Langsrud, Solveig (Journal article; Peer reviewed, 2019)Listeria monocytogenes surviving daily cleaning and disinfection is a challenge for many types of food industries. In this study, it was tested whether whole room disinfection (WRD) with H2O2 mist could kill L. monocytogenes ... -
Whole-Genome Sequencing Analysis of Listeria monocytogenes from Rural, Urban, and Farm Environments in Norway: Genetic Diversity, Persistence, and Relation to Clinical and Food Isolates
Fagerlund, Annette; Idland, Lene; Heir, Even; Møretrø, Trond; Aspholm, Marina Elisabeth; Lindbäck, Toril; Langsrud, Solveig (Peer reviewed; Journal article, 2022)Listeria monocytogenes is a ubiquitous environmental bacterium associated with a wide variety of natural and human-made environments, such as soil, vegetation, livestock, food processing environments, and urban areas. It ...
