Minimally invasive detection of Piscirickettsia salmonis in cultivated salmonids via the PCR

Article Abstract:

A nonlethal method of detecting Piscirickettsia salmonis in cultivated salmonids has been developed. P. salmonis is an intracellular pathogen that has been identified as the cause of infectious diseases affecting salmonid fisheries in Chile. The procedure which employs polymerase chain reaction is directed toward a region of the rRNA operon that is more variable than the region studied by Mauel. Its use quickly demonstrated the existence of a new strain of P. salmonis in rainbow trout from Chile.

Isolates of piscirickettsia salmonis from Scotland and Ireland show evidence of clonal diversity

Article Abstract:

The main reason for salmonid rickettsial septicemia is the Piscirickettsia salmonis which leads to severe mortalities in the aquaculture of Chilean salmonid and it is also becoming an aspect that draws a lot of concern in Ireland and Scotland also since this problem is increasing there also. The experiments are conducted on the organisms like rickettsia all over the world.
