Effectiveness of a proteoliposome‑based vaccine against salmonid rickettsial septicaemia in Oncorhynchus mykiss
Salmonid rickettsial septicaemia (SRS) is a contagious disease caused by Piscirickettsia salmonis, an intracellular bacterium. SRS causes an estimated economic loss of $700 million USD to the Chilean industry annually. Vaccination and antibiotic therapy are the primary prophylactic and control measu...
