Summary of documented, immunoreactive antigens of P. salmonis.

Reference	Immunoreactive antigens of Piscirickettsia salmonis
Kuzyk et al. (71)	6 immunoreactive Ag (2 carbohydrates). Low humoral response in salmonids infected with these Ag
Barnes et al. (72)	6 immunoreactive Ag (2 carbohydrates, 4 proteins). One of the proteins homologous to Hsp60 of Rickettsia tsutsugamushi
Jones et al. (73)	9 protein bands and several non-protein bands were detected by immunoblot. Antigenic homogeneity observed among geographically diverse strains
Jamett et al. (74)	Developed and tested 6 monoclonal antibodies against P. salmonis
