Equine Grass Sickness: Exciting times ahead for this difficult and devastating disease of horses

Research update has brought many research scientists from different institutions and equine charities together

Moredun, which celebrates its Centenary in 2020, has been involved in EGS research over its entire history and is home to the Equine Grass Sickness Fund. The original research started when the disease caused the deaths of many working horses on farms in the 1920s. One hundred years later and the cause of this devastating disease remains elusive, but the consensus is that it is likely to be multi-factorial. There are no treatments or vaccines to prevent disease and around 80 percent of horses contracting the disease do not survive. The disease has a strong association with geography, being more prevalent in the east side of the UK, compared to the west, with Aberdeenshire being the county suffering the most cases annually in the UK. It also has a seasonal pattern and is most common in the spring and early summer and in young, adult equines.

The research update has brought many research scientists from different institutions and equine charities together and it is now available to download. With grateful thanks to the Moredun Foundation, EGSF, British Horse Society and World Horse Welfare for their generosity in funding this research update, Kate Thomson of the Equine Grass Sickness Fund said: “The booklet highlights the vital role that horse owners play in reporting EGS cases, helping us understand the incidence and risk factors associated with the disease.” Roly Owers from WHW said “Equine Grass Sickness is a truly horrible disease that all too often impacts World Horse Welfare directly, with one of our Rescue and Rehoming Centres being in Aberdeenshire and another in Norfolk, both areas with a high EGS prevalence. It is a disease that has been known about for decades yet there is still so much we don’t know about it. So we are pleased to support this publication bringing together the latest information about this pernicious and stubbornly mysterious disease and to work with EGSF in their determination to increase our understanding of it and to find a cure for it.”

But this is just the start! To breathe fresh thinking and approaches into EGS research, Moredun, with partners across many related disciplines such as microbiology, immunology, soil science, plant science, fungal biology, genetics, molecular biology and bioinformatics, have applied to the EGSF to fund a full-time Research Fellow for three years. The main aims of the Fellowship will be to set up a national database and sample biobank with the assistance of a UK wide network of vet ambassadors and horse owners. This will assist greatly in research going forward and will be an important resource available to all EGS researchers. The Fellow will also investigate novel strands of research using the latest technologies, with the assistance of a support network of senior researchers and fellows.

Dr Beth Wells, Moredun explained, “It has been a very exciting time bringing together a truly multi-disciplinary team to work together to provide a fresh look at this devastating disease. The Fellowship will provide a dedicated scientist to set up the national database and sample biobank working with vets and horse owners. The Fellow will also overview EGS research and, working with a highly experienced mentoring team of scientists, will take forward new ideas and research strands.”

Sylvia Ormiston, stud manager at Balmoral Estate added, “I am so excited to hear of the new angles that the Moredun are approaching EGS research with. As a Stud manager and pony owner I know only too well of the damage this dreadful disease can do and I am happy to support the research in any way I can. Together we hopefully make some progress to try and beat this baffling disease.”

Exciting times are indeed ahead for EGS research, by opening up channels and forming an inter-disciplinary, collaborative network, it is hoped to provide answers and solutions to this difficult and devastating disease.
