The species ''Piscirickettsia salmonis'' is a fish pathogen and causes

It lives in cells of infected hosts and cannot be cultured on artificial media.
''Piscirickettsia salmonis'' is nonmotile, whereas the other five genera are motile by using a single
flagellum
A flagellum (; ) is a hairlike appendage that protrudes from certain plant and animal sperm cells, and from a wide range of microorganisms to provide motility. Many protists with flagella are termed as flagellates.
