Novel approach to amoebic gill disease in salmon could benefit humans
Amoebic gill disease is a major disease of farmed Atlantic salmon.

Scientists to repurpose drugs used to treat human parasitic diseases.

Researchers at the University of Glasgow are developing a novel approach to the treatment of amoebic gill disease that could drive down the cost of drugs currently used to treat parasitic diseases in humans.

Caused by the parasite Neoparamoeba perurans, amoebic gill disease (AGD) is major disease of farmed Atrlantic salmon, resulting in severe economic losses across the world. The parasite causes proliferative gill disease, with symptoms including increased mucus on the gills, swollen tissue and breathing difficulties.

In the study, scientists propose to repurpose drugs used to treat human parasitic diseases, such as sleeping sickness, Chagas disease and leishmaniasis, to manage AGD in Atlantic salmon.

Using the University's 'drug discovery pipeline', researchers propose to test the potency of these drugs against Neoparamoeba perurans. The team will then test a candidate drug for activity against ADG in Atlantic salmon at a marine trial site in Ireland.

Researchers hope that by opening new markets for these drugs, it will drive down the cost of parasitic treatment in humans, particularly in the developing world where unaffordable healthcare can lead to millions of unnecessary deaths.

Study co-author Dr Martin Llewellyn, said: “This project is a great opportunity to understand some of the science behind symbiosis, develop a much-needed drug for salmon aquaculture and also hopefully have a beneficial impact on the treatment of diseases that impact the lives of hundreds of millions of people in the tropics.”

Funded by the BBSRC, the project will involve a collaboration with the Marine Institute, Ireland and Dalhousie University, Canada.

Equine Disease Surveillance report released for Q4 2025

News Story 1
 The latest Equine Disease Surveillance report has been released, with details on equine disease from Q4 of 2025.

The report, produced by Equine Infectious Disease Surveillance, includes advice on rule changes for equine influenza vaccination.

Statistics and maps detail recent outbreaks of equine herpes virus, equine influenza, equine strangles and equine grass sickness. A series of laboratory reports provides data on virology, bacteriology, parasitology and toxicosis.

This issue also features a case study of orthoflavivus-associated neurological disease in a horse in the UK.

NSA webinar explores sheep tailing and castration

The National Sheep Association (NSA) is to host a free webinar on the castration and tail docking of lambs.

The webinar, 'Understanding the tailing and castration consultation: A guide for sheep farmers', will be hosted online on Monday, 2 March 2026 at 7.30pm.

It comes during a government consultation into the methods used for these procedures. Farmers are encouraged to engage before the consultation period closes on Monday, 9 March 2026.

The webinar offers clear and actionable guidance to support farmers to contribute meaningfully to the consultation and prepare for potential changes.

On the panel will be former SVS president Kate Hovers, farmer and vet Ann Van Eetvelt and SRUC professor in Animal Health and Veterinary Sciences Cathy Dwyer. Each panel member will utilise their own specialism and expertise to evaluate risks and outcomes to sheep farming.

Find out more about the webinar on the NSA website.
