Francisella sp. (Family Francisellaceae) causing mortality in Norwegian cod (Gadus morhua) farming
Based on sequence data, culturing temperatures and pathogenicity for cod, it is suggested that this Francisella sp. Expand
Occurrence of Francisella piscicida in farmed and wild Atlantic cod, Gadus morhua L., in Norway.
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. Expand
Risk assessment of the environmental impact of Norwegian Atlantic salmon farming
This data indicates that discharge levels in the North Sea are decreasing with age, but the pace of decline is still slow compared with that in the Baltic. Expand
Paranucleospora theridion n. gen., n. sp. (Microsporidia, Enterocytozoonidae) with a Life Cycle in the Salmon Louse (Lepeophtheirus salmonis, Copepoda) and Atlantic Salmon (Salmo salar)
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. Expand
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
Aims:  This study was conducted to clarify the taxonomic status of Francisella sp. strain Ehime‐1, a fish pathogen, in relation to the fish pathogens F. piscicida and F. philomiragia subsp.Expand
Diseases of farmed Atlantic salmon Salmo salar associated with infections by the microsporidian Paranucleospora theridion.
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. Expand
New species in the genus Francisella (Gammaproteobacteria; Francisellaceae); Francisella piscicida sp. nov. isolated from cod (Gadus morhua)
All characteristics taken together support the establishment of GM2212 as a novel species, for which the name Francisella piscicida sp. Expand
Temporal changes in infections with some pathogens associated with gill disease in farmed Atlantic salmon (Salmo salar L)
It is suggested that D. lepeophtherii infections both may be responsible for GD, and cause runting in farmed salmon populations, and high densities of the microsporidian parasite Paranucleospora theridion in the gills coincide with gill disease, making P. theridia a possible primary source to this condition. Expand
Potential disease interaction reinforced: double-virus-infected escaped farmed Atlantic salmon,Salmo salar L., recaptured in a nearby river
It is shown that double-virus-infected escaped salmon ascend a river close to the likely source farms, reinforcing the potential for spread of viruses to wild salmonids. Expand
The marine myxosporean Sigmomyxa sphaerica (Thélohan, 1895) gen. n., comb. n. (syn. Myxidium sphaericum) from garfish (Belone belone (L.)) uses the polychaete Nereis pelagica L. as invertebrate host
This is the fifth elucidated two-host life cycle of a marine myxozoan and S. sphaerica is closest related to Ellipsomyxa spp. Expand
