ABSTRACT: Piscirickettsia salmonis was isolated from cell culture using differential centrifugation and purified on a 30% Percol gradient. The purity of the preparation was assessed by transmission electron microscopy and phage-like particles were found to be associated with some of the P. salmonis isolates examined. This is believed to be the first report of a phage associated with rickettsia from fish.
