A team of researchers led by Tim Mair, CVS Equine Veterinary Director and Specialist in both Equine Internal Medicine and Equine Soft Tissue Surgery at Bell Equine Veterinary Clinic, will review 100 cases of colitis in adult horses and 100 controls referred to seven equine veterinary hospitals in the UK: five CVS equine veterinary hospitals as well as Rossdales Equine Hospital and University of Liverpool’s equine hospital.
A set of diagnostic tests on blood and faeces will be performed in these cases.
The laboratory tests will include: small redworm serology, culture and PCR of faeces for Salmonella spp, PCR of faeces for Clostridioides difficile and Clostridium perfringens, ELISA of faeces for toxins of C.difficile and C.perfringens, PCR of faeces for coronavirus.
The clinical features, laboratory results, treatments and outcomes will also be recorded.
Tim said: “Acute colitis accounts for around 5% of admissions to referral hospitals.
"And of those who are referred with it, half will not survive but there is very limited evidence available.
"So it’s vital that we build our evidence-base of this life-threatening condition.
"We hope that the outcomes of our new study will lead to a greater understanding of the causes and better inform veterinary treatment of colitis in UK adult horses.”
The Colitis in Adult Horses study is supported by a research grant from CVS, and funding for the small redworm ELISA will be given from Austin Davis Biologics.
The study started at the beginning of 2024 and the first horses have been recruited.
The results of the study are expected to be published in 2025.
