Assessment of the potential threat of new and emerging systemic iridoviral diseases for fish and amphibians - SD0422

Summary Objective:
Assessment of the risk of introduction, spread and the likely consequences of systemic iridoviruses (ranaviruses) for European fish and amphibian populations and to provide advice to Defra and the European Commission on appropriate measures to prevent further incursions and spread.

Key Customer Purpose:
The project aims to assess the threat of systemic iridoviruses (ranaviruses) to farmed and wild freshwater fish and amphibian wildlife in the UK and elsewhere in the EU. A survey of disease in EU-produced and imported ornamental fish and in pet or wild amphibians will be conducted to gain knowledge of the current presence of ranaviruses and indicate the potential for the aquatic pet trade to be a route of introduction and spread. Applying epidemiological principles, a risk assessment model (RAM) will be developed to assess the potential pathways of spread and likely impact of those viruses showing greatest virulence in the experimental trials. Determine the susceptibility of major European fish and amphibian species to selected ranaviruses. CEFAS will test two of the fish species (Atlantic salmon and carp) and five amphibian species (common frog, green frog, smooth newt, natterjack toad and crested newt) to a panel of EU and non-EU ranaviruses under experimental challenge conditions.
