Immune parameters in the intestine of wild and reared unvaccinated and vaccinated Atlantic salmon (Salmo salar L.).

摘要: Abstract Forming a barrier to the outside world, gut mucosa faces challenge of absorbing nutrients and fluids while initiating immune reactions towards potential pathogens. As continuation our previous publication focusing on regional intestinal morphology in wild caught post smolt spawning Atlantic salmon, we here investigate selected parameters compare wild, reared unvaccinated vaccinated smolts. We observed highest transcript levels for most immune-related genes smolts followed by finally smolts, indicating that farming conditions like commercial feed vaccination might contribute more alerted system gut. In all groups, higher transcripts were second segment mid-intestine posterior segment. life stages investigated here, found no indication previously suggested population T cells expressing MHC class II nor RAG1 expression.
