Immune-relevant genes expressed in rainbow trout following immunisation with a live vaccine against Ichthyophthirius multifiliis.

Rainbow trout Oncorhynchus mykiss were immunised by intra-peritoneal injection using a live vaccine based on Ichthyophthirius multifiliis (Ich) theronts, which previously has shown protection against white spot disease. Samples were taken pre-vaccination and on Day 1, 7, 21 and 28 post-immunisation (p.i.
