Calcitonin gene-related peptide concentration in cerebrospinal fluid and serum in horses affected by trigeminal-mediated headshaking. Trigeminal-mediated headshaking (TMHS) in horses shares clinical features with human trigeminal neuralgia (HTN). Increased levels of the neuropeptide calcitonin gene-related peptide (CGRP) have been found in the blood and cerebrospinal fluid (CSF) of HTN patients. Inhibition of CGRP in humans has shown promise for pain relief. Data on CGRP in horses affected by TMHS are currently lacking but if quantifiable and validated, could assist in developing new diagnostic and more rational therapeutic approaches. Objective: This study aimed to quantify and correlate CGRP concentrations in the serum and...

Synovial chemokine and cytokine profiles in horses with and without systemic Borrelia burgdorferi infection. Lyme arthritis, a well-documented subtype of arthritis in humans and dogs, is caused by Borrelia burgdorferi and spread primarily through ticks (Ixodes spp.). While Lyme disease in horses is known to cause a variety of clinical signs, its involvement in the development of equine arthritis is controversial. As climate change enables tick populations to expand, more horses could be exposed to B. burgdorferi; therefore, a greater understanding of how Lyme disease affects joints is critical to preserving soundness. Objective: To determine if systemic, naturally occurring Lyme disease had a discern...
Descriptive epidemiology of long-term injuries in jump racing Thoroughbreds in Great Britain. Race-related injuries in horse racing, especially those requiring extended recovery, are a welfare concern and threaten the sport's social licence.

Clinical signs, clinical pathology and outcomes in horses infected naturally with equine encephalosis virus. Equine encephalosis (EE) is caused by an Orbivirus from the family Sedoreoviridae and is thus similar to African horse sickness (AHS) and Bluetongue viruses (BTV). These viruses are transmitted by Culicoides midges. Equine encephalosis can infect horses, donkeys and zebras sub-clinically while only horses develop clinical disease. The vector's distribution is climate-dependent with evidence for circulation in Southern Africa, the Middle East and India. Global warming could facilitate the expansion of this distribution and consequently the potential spread into Europe should not be overlooked. ...
Bridging hosts: Domestic horse density and Hendra virus spillover risk in a changing landscape. Anthropogenic climatic and landscape change can drive behavioural shifts in wildlife and thus lead to increased risk of pathogen exposure for humans and domestic animals. While spillover research often focuses on the reservoir hosts or ongoing transmission in humans, livestock and companion animals can play important roles as bridging and amplifying hosts, facilitating the emergence of highly pathogenic diseases. Objective: To investigate the distribution and density of domestic horses in the context of their role as bridge hosts for Hendra virus and build models to study zoonotic emergence. M...
The horse cardiac transcriptome: Moving towards a molecular understanding of atrial fibrillation.
