Histological and bacteriological changes in intestine of beluga (Huso huso) following ex vivo exposure to bacterial strains
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
In the present study the intestinal sac method (ex vivo) was used to evaluate the interactions between lactic acid bacteria and staphylococci in the gastrointestinal (GI) tract of beluga (Huso huso). The distal intestine (DI) of beluga was exposed ex vivo to Staphylococcus aureus, Leuconostoc mesenteroides and Lactobacillus plantarum. Histological changes following bacterial exposure were assessed ...
Do stocking densities affect the gut microbiota of gibel carp (Carassius auratus gibelio) cultured in ponds?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
The aim of the present study was to evaluate the intestinal microbial communities of gibel carp (Carassius auratus gibelio) cultivated in two beach ponds at different stocking densities. The two ponds were both ~3.33 hm2 in acreage and ~1.5 m in depth. The stocking densities included one intensive with 2 fish m–3 while the other treated as semi-intensive with 1 fish m–3. The gut microbiota (both ...
Evaluation of prebiotic and probiotic effects on the intestinal gut microbiota and histology of Atlantic salmon (Salmo salar L.)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
In the present study the impact on gut microbiology and indigenous gut histology of Atlantic salmon (Salmo salar L.) was investigated following feeding of a control and a prebiotic (EWOS prebiosal®) diet and ex vivo exposure to saline or the probiotic bacterium Carnobacterium divergens. The results showed that ex vivo exposure of C. divergens at 108 CFU ml-1 did not cause cell damage to the intestine ...
Evaluation of probiotic strain Bacillus subtilis C-3102 as a feed supplement for koi carp (Cyprinus carpio)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
In this study, the effects of dietary probiotic Bacillus subtilis C-3102 (Calsporin®) on the growth performance, predominant intestinal microbiota, expression of cytokines genes in three organs (liver, intestine and kidney) and
protection against Aeromonas hydrophila infection of koi carp were investigated. Fish were fed two different diets, 1-control diet (non-supplemented) and 2-experimental diet ...
Description of the processes in the value chain and risk assessment of decomposition substances and oxidation products in fish Oils. Opinion of Steering Committee of the Norwegian Scientific Committee for Food Safety
(Research report; Forskningsrapport, 2011-10-19)
The Norwegian Scientific Committee for Food Safety (VKM) has been asked by the Norwegian Food Safety Authority to perform a health risk assessment on decomposition substances and oxidation products in fish oils intended for human consumption except pharmaceuticals. Seal and/or krill oil intended for human consumption might be included but in separate chapters. EU’s hygiene regulations for the ...
