Antibiotics against bovine mastitis pathogens : resistance and novel targets
Nordraak, Anne Olsdatter Ohren (Master thesis, 2022)Bovine mastitis is the most frequent disease of dairy cattle and the major cause of antibiotic usage in dairy production. It causes impaired animal wellbeing, economical losses and food waste all over the world. This thesis ... -
Bruk av CRISPR interferens til å studere gener i Staphylococcus aureus som er viktige for interaksjon med bakterier i jurmikrobiotaen
Petersheim, Ingrid (Master thesis, 2022)Staphylococcus aureus er et av de hyppigste årsakene til utvikling av bovin mastitt, som er en av de mest utfordrende sykdommene hos melkekyr på verdensbasis. Mastitt forårsaker problemer som redusert helsetilstand hos ... -
Bruk av CRISPR-interferens til å identifisere gener involvert i toleranse mot antibiotika i Staphylococcus aureus
Frøynes, Anette Heidal (Master thesis, 2020)Staphylococcus aureus, ofte kalt gule stafylokokker, er en svært viktig human bakteriell patogen. Bakterien forårsaker en rekke humane kliniske sykdommer som strekker seg fra lokaliserte, avgrensede hud- og bløtvevsinfeksjoner ... -
CAAX-proteiner og sekresjon av virulensfaktorer i Streptococcus pneumoniae
Heiland, Catharina Sørlie (Master thesis, 2018)CAAX amino-terminal protease familien (heretter omtalt som CAAX-proteiner), består av antatt membranbundne metallproteaser. Dette er proteiner som finnes i både eukaryote- og prokaryote celler, men deres funksjon i prokaryote ... -
Characterization of a novel cell wall binding domain of the fratricin CbpD from Streptococcus dysgalactiae
Allred, Jennie Ann (Master thesis, 2022)The Streptococcus genus contains a large variety of species across seven subgroups. The lesser-known Streptococcus dysgalactiae of the pyogenic group is both a human and an animal pathogen and is subsequently divided into ... -
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 ... -
Development of novel peptide-based antibiotics
Sæbø, Ingvill Pedersen (Master thesis, 2020)The discovery of antibiotics has drastically improved global health by curing previously untreatable infections. Due to persistent and prophylactic use of antibacterial drugs, both in humans, animals and agriculture, the ... -
Exploring the role of novel biofilm-associated genes in Staphylococcus aureus
Moe, Rebekka (Master thesis, 2022)Staphylococcus aureus er en opportunistisk humanpatogen bakterie med evnen til å forårsake en rekke alvorlige infeksjoner. Bakteriens suksess kan tilskrives dens mange varierte virulensfaktorer, inkludert dannelsen av ... -
Funksjonelle studier av SmdA : et nytt protein involvert i celledeling og varmetoleranse i Staphylococcus aureus
Knutsen, Tiril Mathiesen (Master thesis, 2022)Staphylococcus aureus er et av de viktigste patogenene å studere i sammenheng med infeksjonssykdommer i samfunnet, da det de seneste årene er observert en betydelig økning av resistente stammer mot antibiotika. For å kunne ... -
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 ... -
The impact of impaired biosynthesis of menaquinone on biofilm and macrocolony formation in Staphylococcus aureus
Olsen, Henriette Sætre (Master thesis, 2021)Staphylococcus aureus (S. aureus) is known to cause biofilm-associated infections in humans. Biofilms are surface associated microbial communities and is characterized as three-dimensional structures with cells embedded ... -
Karakterisering av Fusiformicin : et nytt antimikrobielt stoff med aktivitet mot Streptococcus pneumoniae
Sandegren, Vilde (Master thesis, 2022)Antibiotikaresistens regnes som et av de største problemene som verden står ovenfor i dag i forhold til global helse, matsikkerhet og utvikling. Det arbeides med å finne nye antibiotika med aktivitet mot bakterier som ... -
Molecular characterization of single tumor cells in breast cancer
Monrad, Julie Synøve Myre (Master thesis, 2021)Breast cancer is the most common cancer among women in Norway, with 3726 new cases and 598 deaths registered in 2019. The five-year relative survival rate has increased and is now at 92%. Breast cancer is one of the few ... -
Overuttrykk, rensing og karakterisering av fratrisinet CbpD fra Streptococcus dysgalactiae
Schultheiss, Anna Teigen (Master thesis, 2021)Streptococcus pneumoniae er en viktig humanpatogen. Mye forskning er derfor blitt utført på denne og nært beslektede streptokokker, men man har ikke like mye kunnskap om de mer perifere slektningene av denne bakterien, ... -
Screening and characterization of bacteriocins produced by lactic acid bacteria against Lactococcus garvieae
Holivololona, Lalaina (Master thesis, 2018)Infectious diseases caused by bacteria have ravaged humankind multiple times in history until the discovery of antibiotics. Now, several decades later, bacteria resistant to nearly all antibiotics have been reported due ... -
