Project description:To obtain the site-by-site methylation landscape of the infectious spleen and kidney necrosis virus (ISKNV) genome, whole-genome bisulfite sequencing (WGBS) was performed on an ISKNV strain from 3 duplicate samples.
Project description:Infectious pancreatic necrosis (IPN) is a serious viral disease that causes significant economic losses in salmon aquaculture. To characterize the host-pathogen relationship in IPN, we analysed transcriptional profiles of salmon head kidney (SHK-1) cells infected with infectious pancreatic necrosis virus (IPNV) at three timepoints over six days (at 1, 3 & 6 days post infection. The transcriptome was investigated using the TRAITS / SGP 16950-feature Atlantic salmon cDNA microarray, which is enriched for genes with functions related to the immune response.
Project description:Oral immunization of trout against infectious pancreatic necrosis virus (IPNV) have been recently reported by using a DNA vector coding the viral capsid VP2 gene encapsulated in alginate microspheres. We report here an study of the transcripts in head kidney and pyloric ceca 7 days after oral vaccination of rainbow trout by using a newly designed rainbow trout 60-mer oligo microarray focused in their immune-related genes.

We report here an study of the transcripts in head kidney and pyloric ceca 7 days after oral vaccination of rainbow trout by using a newly designed rainbow trout 60-mer oligo microarray focused in their immune-related genes. Trout were obtained from 4 different farms, one group of trout was defined as belonging to one of the farms. Each of the trout 4 groups were divided into two subgroups of 6 trout for each subgroup. Subgroup I was orally vaccinated with 10 M-BM-5l of suspension of the vaccine microspheres each containing 10 M-BM-5g of pcDNA-VP2 diluted in 10M-BM-5l of PBS, while subgroup II received similar microspheres suspension but pcDNA. Head kidney and pyloric ceca were collected from each subgroup and RNA was extracted.
