Isolates of Piscirickettsia salmonis from Scotland and Ireland show evidence of clonal diversity.
Salmonid rickettsial septicemia, caused by Piscirickettsia salmonis, causes major mortalities in Chilean salmonid aquaculture and is an increasing problem in Atlantic salmon in Ireland and Scotland. Analysis of 16S-to-23S internal transcribed sequences and 16S ribosomal DNA (rDNA) shows that Irish isolates of P. salmonis form two new groups of the organism while Scottish isolates cluster together with Norwegian and Canadian isolates from Atlantic salmon.
