Salmonid Rickettsial Septicemia (SRS) was first reported in Chile in the year 1989 on farmed Coho Salmon. Later the disease was observed on Atlantic salmon and up to 90% mortality was reported. SRS is present in North America and Europe.

SRS is caused by the gram negative bacterium Piscirickettsia salmonis, which is obligate intracellular.

The disease was originally predominant in Coho salmon but it is now recognized to cause serious losses in all farmed salmonid fish species including Atlantic salmon, Rainbow (steelhead) trout, Chinook salmon, Pink salmon and Masu salmon.

Salmonid Rickettsial Septicemia (SRS) Immunofluorescent test from Ango is an immuno-diagnostic assay for the detection of Piscirickettsia salmonis in fish tissue and fluid samples. The test high specificity and sensibility are ideal for the correct, rapid and opportune diagnosis of the disease.
