A comparative analysis of lactic acid bacteria isolated from honeybee gut and flowers, with focus on phylogeny and plasmid profiling
Linjordet, Marte S. (Master thesis, 2016-08-10)Apis mellifera (honeybee) are of huge value as they are the most important pollinator worldwide. Declines in honeybee populations have made the honeybee subject to much scientific research. Lactic acid bacteria (LAB) have ... -
A comparative analysis on phylogeny, genetics and selected phenotypes of lactic acid bacteria isolated from gut microbiota of honey bee versus flowers
Gallefoss, Ingvild (Master thesis, 2016-08-10)From the bee gut samples 190 bacteria isolates were obtained. Purified plasmid DNA extracts were screened for plasmids on an agarose gel by electrophoresis to determine their plasmid profiles. The purpose of the plasmid ... -
Bacteriocin-based treatment of Staphylococcus haemolyticus biofilm
Brønner, Mikkel (Master thesis, 2020)Antibiotics have long been used to treat infections caused by pathogenic and multidrugresistant (MDR) bacteria. However, an increasing number of bacteria, including pathogenic bacteria, have developed resistance against ... -
Bacteriocins : from discovery to characterization and applications
Oftedal, Thomas Førland (PhD thesis;2023:74, Doctoral thesis, 2023)Multidrug resistant bacteria have become a major concern in both human and veterinary medicine. Due to the waning efficacy of many antibiotics, new antimicrobial agents are needed. Bacteriocins are ribosomally ... -
Characterization of Lactic Acid Bacteria from infants gut with antimicrobial activity against Lactobacillus rhamnosus GG
Andersen, Amanda Morken (Master thesis, 2018)There are major individual differences in how the probiotic strain Lactobacillus rhamnosus GG (LGG) colonizes the intestine of infants. Understanding these differences will be of great importance in relation to the use of ... -
Co-immunoprecipitation with the multi-peptide bacteriocin GarKS immunity protein
Oftedal, Thomas Førland (Master thesis, 2019)Garvicin KS (GarKS) is a bacteriocin recently discovered in Lactococcus garvieae belonging to a novel group of multi-peptide bacteriocins, whose receptor and mode of action is unknown. In this thesis heterologous expression ... -
Cost of resistance : stress tolerance and gene expression in wild type and mutant strains of Staphylococcus haemolyticus LMGT4071
Solberg, Kristin Kleivan (Master thesis, 2022)Several studies have shown that a bacteria’s development of resistance to an antimicrobial substance often comes with a cost related to their general fitness and adaptation to environmental changes. Further research is ... -
Dynamics of PML bodies during epidermal cell division in mice
Olstad, Ingrid (Master thesis, 2016-08-10)The tumor suppressor protein promyelocytic leukemia (PML) is the most common fusion partner to the retinoic acid receptor alpha (RARA) in acute promyelocytic leukemia (APL) patients. The two therapeutic drugs arsenic ... -
Identification of RseP as a receptor for hybrid bacteriocin H1 in emerging pathogen Staphylococcus haemolyticus
Bartkiewicz, Karolina Teresa (Master thesis, 2020)Staphylococcus haemolyticus is an emerging pathogen which may transfer multi-drug resistance genes to highly virulent Staphylococcus species. S. haemolyticus is a biofilm-producing bacterium and one of the most frequent ... -
Identifying coevolution of class IIa bacteriocin and their immunity protein
Kroken, Gard (Master thesis, 2018)Class IIa bacteriocins are Antimicrobial peptides found in many lactic acid bacteria. Here they serve as a weapon against competing bacteria by causing cell leakage through pore-formation in the membrane. An immunity protein ... -
Immunotherapeutic targeting of tumor-associated macrophages
Haack, Beatrice (Master thesis, 2018)The development of CAR T cell technology allows for MHC-independent recognition of a native target antigen by T cells. In august 2017, the first CD19-specific CAR T cell therapy was approved in the U.S. for the treatment ... -
In vivo assessment of the gene encoding the membrane bound protease Eep, in virulence
Edwin, Oliver (Master thesis, 2019)The increasing prevalence of antimicrobial resistance and the lack of innovation in developing new antibiotics has only emphasised the need to develop new antimicrobials. Therefore, research has focused on antimicrobials ... -
Inosine-independent roles of human Endonuclease V
Solbakk, Hannah Winther (Master thesis, 2020)Endonuclease V (EndoV) is a highly conserved enzyme with specificity for inosines in nucleic acids. The bacterial EndoVs are active both on DNA and RNA, whereas the human (h) homolog (hEndoV) cleaves only at inosines in ... -
iPSC-/ESC-derived hepatic stellate cells in 2D and 3D
Melsonchandrakumar, Felixkumar (Master thesis, 2022)Liver Fibrosis is a major concern for the world as it causes chronic inflammation which again induces an unhealthy and abnormal healing response. Most common causes to liver fibrosis are alcohol consumption, non-alcoholic ... -
Isolation and characterization of wide host range vibriophages for therapeutic use in aquaculture
Larsen, Ingrid Sofie Siqveland (Master thesis, 2017)The aquaculture industry is one of the fastest growing food-producing sectors in the world, but the industry is struggling with huge losses due to bacterial infections. Several species of Vibrio are ubiquitous to marine ... -
Lysophosphatidic acid (LPA) regulation of collective cell migration
Sangnæs, Sofie Persdatter (Master thesis, 2021)The human body is covered by a protective barrier, the skin. The skin is daily subjected to cuts and bruises, wounds that are normally healed without scars. However, sometimes the wound healing process of the skin fails, ... -
Metabolite toxicity and DNA damage in maple syrup urine disease
Lien, Andrea Fredrikstad (Master thesis, 2017)Maple Syrup Urine Disease (MSUD) is a metabolic disease where the branched-chain amino acids (BCAAs) and their corresponding branched-chain α-keto acids (BCKAs) accumulates in the cells, because they have a defective ... -
Modulation of gut microbiota by pre/probiotics and the potential health promoting outcomes for the host
Umu, Özgün Candan Onarman (PhD Thesis;2016:42, Doctoral thesis, 2020-11-19)Gut microbiota is considered an organ that co-develops with the host throughout its life. The composition and metabolic activities of gut microbiota are subjected to a complex interplay of the host genetics and environmental ... -
