Ellen Beate Tysvær (left) is doing her BSc in biosciences at Department of Biosciences, UiO. She received a fellowship from UiO:Life Sciences to work as a summer student in the MicroPath group. She is working on a project isolating extracellular vesicles from E. coli expressing outer membrane proteins from the fish bacterial pathogen Yersinia ruckeri and testing them as a vaccine against the disease yersiniosis in aquaculture. Ellen-Beate is supervised by our PhD student Verena Mertes (right) in the laboratory.

MSc Rebekka Rolfsnes, an employee of the Norwegian start-up biotech company Adjutec Pharma, started her PhD with us the first of April 2022. We are glad to have Rebekka back in the group after she did her MSc thesis with us in 2020 on bacterial fish vaccines. Rebekka will do her PhD on the project entitled: The novel antimicrobial resistance breaker APC247 – studies on mechanism of action (MoA) and resistance development to a putative dual SBL/MBL inhibitor. The project is funded by the Norwegian Research Council.

With the help of Fabio Antenucci, Klaus Qvortup and Michael Johnson we performed cryoEM imaging of bacterial extracellular vesicles from the fish pathogen Yersinia ruckeri. The vesicles were isolated by Verena Mertes from the Y. ruckeri ompA mutant. The cryoEM was performed at CFIM - Core facility for Intergrated Microscopy at University of Copenhagen.
