Application of a novel amplicon-based sequencing approach reveals the diversity of the Bacillus cereus group in stored raw and pasteurized milk
Porcellato, Davide; Aspholm, Marina; Skeie, Siv Borghild; Mellegård, Hilde (Peer reviewed; Journal article, 2018)Members of the Bacillus cereus sensu lato (B. cereus group) are spore-forming organisms commonly associated with spoilage of milk and dairy products. Previous studies have shown, by using 16S marker gene sequencing, ... -
Biochemical and mutational analysis of spore cortex-lytic enzymes in the food spoiler Bacillus licheniformis
Aspholm, Marina; Kollerud, Kristian K; Høgberg Hansen, Helge C; Granum, Per Einar; Christie, Graham; Lindbäck, Toril (Journal article; Peer reviewed, 2019)Bacillus licheniformis is frequently associated with food spoilage due to its ability to form highly resistant endospores. The present study reveals that B. licheniformis spore peptidoglycan shares a similar structure to ... -
Commensal E. coli Stx2 lysogens produce high levels of phages after spontaneous prophage induction.
Iversen, Hildegunn; L'Abee-Lund, Trine Marie; Aspholm, Marina; Arnesen, Lotte Pia Stenfors; Lindbäck, Toril (Journal article; Peer reviewed, 2015) -
Enterohaemorrhagic E. coli O103:H25 modulates expression of LEE-encoded virulence genes in response to direct cell-cell contact with the gut commensal Bacteroides thetaiotaomicron
Kijewski, Anne Cecilie Riihonen (Master thesis, 2015-08-03)Enterohemorrhagic Escherichia coli (EHEC) is a foodborne pathogen of the colon that causes disease with varying severity. Symptoms range from mild diarrhea to hemolytic uremic syndrome (HUS), which at worst can be fatal. ... -
Genome-wide transcriptional profiling of Clostridium species during sporulation
Jelsness, Paulius (Master thesis, 2016-11-22)Dormancy strategies utilized by bacteria contribute to their survival under adverse conditions, as well as persistence and transmission between hosts. The formation of endospores produces some of the most resilient forms ... -
High diversity in the regulatory region of Shiga toxin encoding bacteriophages
Fagerlund, Annette; Aspholm, Marina; Wegrzyn, Grzegorz; Lindbäck, Toril (Peer reviewed; Journal article, 2022)Background: Enterohemorrhagic Escherichia coli (EHEC) is an emerging health challenge worldwide and outbreaks caused by this pathogen poses a serious public health concern. Shiga toxin (Stx) is the major virulence factor ... -
Microbial interactions : effects on virulence in Enterohaemorrhagic Escherichia coli (EHEC)
Iversen, Hildegunn (PhD Thesis;2015:51, Doctoral thesis, 2017-07-13)Enterohaemorrhagic Escherichia coli (EHEC) is an emerging food borne pathogen associated with a number of outbreaks worldwide, and is a serious public health threat. The symptoms of the disease can range from mild diarrhoea ... -
