Immersion Challenge of Atlantic Salmon (Salmo salar) yolk sac fry with Yersinia ruckeri.
Drågen, Martha Kristine Rindarøy (Master thesis, 2020)De siste årene har forskning som omhandler interaksjoner mellom vert og bakterier gått fra å hovedsaklig fokusere på de negative sidene, til å også inkludere gunstige funksjoner som for eksempel bidrag til fordøyelsen, ... -
The impact of phage treatment on bacterial community structure is minor compared to antibiotics
Gundersen, Madeleine S.; Fiedler, Alexander Willi; Bakke, Ingrid; Vadstein, Olav (Peer reviewed; Journal article, 2023)Phage treatment is suggested as an alternative to antibiotics; however, there is limited knowledge of how phage treatment impacts resident bacterial community structure. When phages induce bacterial lysis, resources become ... -
Janthinobacterium Strains Isolated from Rearing Systems for Atlantic Salmon Fry Growth Characteristics, Violacein Production and Evolution of the Violacein Operon
Mølmen, Nora Persen (Master thesis, 2021)Janthinobacterium lividum er tidligere isolert fra amfibieskinn og menneskehud. Arten er kjent for å produsere det lilla pigmentet violacein, som har vist seg å ha antifungale, antibakterielle, antivirale og antitumorale ... -
The microbiota of yolk sac fry of Atlantic salmon: Development, disturbances, and role in host protection
Fiedler, Alexander Willi (Doctoral theses at NTNU;2023:349, Doctoral thesis, 2023)Norsk sammendrag Bakterier finnes overalt rundt oss og på hver plante, menneske eller overflate. Disse bakteriene kaller vi for «mikrobiomen», før eksempel kaller vi bakteriene som bor i tarmen vår vår «tarm mikrobiom». Denne ... -
Phage therapy minimally affects the water microbiota in an Atlantic salmon (Salmo salar) rearing system while still preventing infection
Fiedler, Alexander Willi; Gundersen, Madeleine S.; Vo, Toan Phuc; Almaas, Eivind; Vadstein, Olav; Bakke, Ingrid (Peer reviewed; Journal article, 2023)Excessive usage of antibiotics threatens the bacterial diversity in the microbiota of animals. An alternative to antibiotics that has been suggested to not disturb the microbiota is (bacterio)phage therapy. In this study, ... -
The stability and composition of the gut and skin microbiota of Atlantic salmon throughout the yolk sac stage
Fiedler, Alexander Willi; Drågen, Martha Kristine Rindarøy; Degré Lorentsen, Eirik; Vadstein, Olav; Bakke, Ingrid (Peer reviewed; Journal article, 2023)The bacterial colonization of newly hatched fish is important for the larval development and health. Still, little is known about the ontogeny of the early microbiota of fish. Here, we conducted two independent experiments ...
