What is it?
Piscirickettsia salmonis is a bacterium that causes piscirickettsiosis. This disease can cause high mortality in salmon that live in a marine environment. It is a pathogen of concern for many international fish health regulatory authorities, and it is common to test fish for this bacterium as part of export certification testing.
P. salmonis is a unique bacterium because it invades and replicates inside of the host fish’s cells. Unlike most other bacteria, which are cultured in the laboratory on agar plates, P. salmonis must be grown in tissue culture (see image below). This makes it different and sometimes more difficult to test for than most fish bacterial pathogens.
