Comparative evaluation of experimental challenge by intraperitoneal injection and cohabitation of Atlantic salmon (Salmo salar L) after vaccination against Piscirickettsia salmonis (EM90‐like)

Journal of Fish Diseases, Volume 42, Issue 12, Page 1713-1730, December 2019., 2019
Abstract The Chilean aquaculture has been challenged for years by piscirickettsiosis. A common prophylactic measurement to try to reduce the impact from this disease is vaccination, but the development of vaccines that induce satisfactory protection of the fish in the field has so far not been successful.

Effects of Increased Water Salinity and Temperature on the Development of Rainbow Trout Fry Syndrome (RTFS) Caused by Flavobacterium psychrophilum

Journal of Fish Diseases, Volume 49, Issue 2, February 2026.
ABSTRACT Flavobacterium psychrophilum, the etiological agent of Rainbow Trout Fry Syndrome (RTFS) and Bacterial Coldwater Disease (BCWD), causes varying degrees of disease and mortality in salmonid aquaculture worldwide. Because its treatment relies on the use of antimicrobials, alternative interventions are of environmental and economic interest.
