Epidemiology of Salmonid Rickettsial Septicemia (SRS) in Farmed Salmon: The Role of Sea Lice Infestations in Mortality Risk

Journal of Fish Diseases, Volume 49, Issue 5, May 2026.
ABSTRACT Piscirickettsia salmonis, the causal agent of salmonid rickettsial septicemia (SRS), is the main pathogen affecting farmed salmonids in Chile. Outbreaks of SRS lead to substantial economic losses for producers. Many determinants related to SRS outcomes are still poorly understood.
