The apparent absence of the bacterium in wild populations of cod in the northern parts of Norway and its widespread occurrence in wild cod from southern part of Norway is believed to relate to differences in seawater temperatures.

It is suggested that P. theridion should be given status as a new species in a new genus based on characteristics of the morphology, unique development involving a vertebrate fish as well as a crustacean ectoparasite host, and the results of the phylogenetic analyses.
Elevation of Francisella philomiragia subsp. noatunensis Mikalsen et al. (2007) to Francisella noatunensis comb. nov. [syn. Francisella piscicida Ottem et al. (2008) syn. nov.] and characterization…

Quantification of pathogens associated with PGI, PD, HSMI and CMS diagnoses showed that P. theridion levels are high in southern Norway, and may therefore play a role in susceptibility and disease development, however, among the different diagnoses, fish with P GI are particularly heavily infected with P.Theridion.

Evidence is presented for the association of a novel species of Chlamydiales with epitheliocystis in Atlantic salmon and a new member of the family Simkaniaceae is proposed for inclusion in the candidate genus Syngnamydia.
Potential disease interaction reinforced: double-virus-infected escaped farmed Atlantic salmon,Salmo salar L., recaptured in a nearby river
