Moritella viscosa

Moritella viscosa is one of the causative agents of winter ulcer. The disease affects both Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) and results in increased mortality rates as well as major economical losses due to downgrading fish at slaughter.

Data Downloads

This project is ongoing and data for this organism will be made available in due course.

The aim on this project will be to sequence the genomes of M. viscosa and A. wodanis. Since A. wodanis and A. salmonicida are closely related, and both important economic fish pathogens, this will provide an excellent comparator genome. Also this will allow the identification of genes that are potentially involved in virulence, and may highlight new targets for vaccine development. However, since we aim to look at the possible interactions between M. viscosa and A. wodanis the genomes will also support the biological program that will run alongside the genome sequencing.

Data Use Statement

This sequencing centre plans on publishing the completed and annotated sequences in a peer-reviewed journal as soon as possible. Permission of the principal investigator should be obtained before publishing analyses of the sequence/open reading frames/genes on a chromosome or genome scale. See our data sharing policy.
