The effect of full-limb flexion tests on static and dynamic muscle activity and locomotion asymmetry in owner-sound horses
Jonkhart M, Serra Bragança FM, Smit IH, Brommer H and Suskens JJM
Flexion tests are commonly used in equine locomotion examinations to identify underlying locomotor issues, yet their neuromuscular effects remain poorly understood. Response variability raises concerns about their clinical value in lameness assessments and pre-purchase evaluations.
Localisation and outcome of presumed thoracolumbar vertebral stress fracture in 35 UK Thoroughbred racehorses using nuclear scintigraphy
Chapple AR, Daglish J, Stover SM, Slipchenko N and Phillips KL
Stress fracture is an important cause of mortality and morbidity in racing Thoroughbreds. Nuclear scintigraphy is the imaging modality of choice for investigating unlocalised stress-related bone remodelling in horses. Stress fractures of the caudal lumbar vertebral column have been previously described in both racing Quarter horses and racing Thoroughbreds post-mortem. There is a lack of literature describing the imaging appearance of vertebral stress fractures in racehorses ante-mortem.

The horse cardiac transcriptome: Moving towards a molecular understanding of atrial fibrillation
Haugaard SL, Nissen SD, Schneider MJ, Birk JB, Carstensen H, Hopster-Iversen C, Altıntaş A, Barrès R, Kjøbsted R, Wojtaszewski JFP, Herum KM, Jespersen T and Buhl R
High recurrence rates after atrial fibrillation (AF) treatment may be driven by myocardial changes induced by the arrhythmia itself. Understanding the molecular mechanisms behind these changes is crucial for developing targeted therapies and improving outcomes.
A novel kirkovirus may be associated with equine gastrointestinal disease
Haywood LMB, Clark A, Hause B and Sheahan B
Many cases of equine enterocolitis are suspected to be infectious in nature, but no pathogen is identified in many cases.

Reliability, agreement and variability of a markerless computer vision algorithm for equine gait analysis under field conditions
Key K, Berg K, Kirkegaard J, Andresen KR and Skov Hansen S
Computer vision-based algorithms offer accessible alternatives for equine gait analysis but require thorough assessment under diverse conditions.
Quantitative assessment of gait alterations and variability in sulky-driven Standardbred trotters after a standardised exercise test
Aarts RM, Smit IH, Ferraz GC, Rhodin M, Serra Braganca FM and Hernlund E
Assessment of equine metabolic and locomotory responses to quantified levels of physical exercise is needed to support the creation of tailored protocols for optimal training adaptation. The locomotory response to exercise in horses is not fully understood.
Reining in strangles: Absence of disease in horses vaccinated with a DIVA-compatible recombinant fusion protein vaccine, Strangvac, following natural exposure to Streptococcus equi subspecies equi
Gröndahl G, Righetti F, Aspán A, Bjerketorp J, Frosth S, Frykberg L, Jacobsson K, Guss B, Paillot R, Flock JI, Henriques-Normark B and Waller AS
Strangles, caused by Streptococcus equi subspecies equi (S. equi), is a prevalent infectious disease of horses. This is the first report on the use of a new vaccine, Strangvac, in a natural outbreak of strangles.

Descriptive epidemiology of long-term injuries in jump racing Thoroughbreds in Great Britain
McDonald S, Verheyen KLP, Chang YM and Allen SE
Race-related injuries in horse racing, especially those requiring extended recovery, are a welfare concern and threaten the sport's social licence. Previous studies predominantly report on fatalities; however, serious non-fatal musculoskeletal injuries often end horses' racing careers or have a high recurrence risk. No recent studies have described or quantified long-term injuries (LTIs) in racing Thoroughbreds, which is essential to inform targeted risk prevention strategies.
Synovial chemokine and cytokine profiles in horses with and without systemic Borrelia burgdorferi infection
Clark KF, Lemcke RA, Gasiorowski JC and Wagner B
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.
Physiological and behavioural effects of continuous remifentanil-xylazine administration in donkeys
Damasceno KFA, Mouta AN, Alves LSA, Arcoverde KN, Aragão HR, Cavalcante JM and Veras de Paula V
Remifentanil and xylazine are used as continuous infusions to facilitate standing surgery in horses. Their use for this purpose has not been reported in donkeys.
Enhanced detection of equine strongyles: Insights from morphological and nemabiome metabarcoding approaches in northern Iran
Mohtasebi S, Ahn S, Karimi M, Saberi M, Gilleard JS and Poissant J
Strongyles pose significant health concerns for equids globally. Strongyles, comprising over 60 species, can lead to severe morbidity and mortality, with Strongylus vulgaris posing higher risks due to its migratory behaviour. Routine diagnostic methods, such as faecal egg counts, lack species-level resolution, while traditional morphological techniques require advanced expertise. DNA metabarcoding offers a high-throughput alternative.
Bridging hosts: Domestic horse density and Hendra virus spillover risk in a changing landscape
Linnegar B, Hoegh A, McCallum H and Peel AJ
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.
Clinical signs, clinical pathology and outcomes in horses infected naturally with equine encephalosis virus
Piketh G, Viljoen A and Eberhardt C
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.
Agreement of the performance of equine electrocardiogram recording devices for ECG complexity analysis
Alexeenko V, Anchan DS, Ter Woort F, Ribonnet C, van Erck E, Marr C and Jeevaratnam K
Non-linear equine electrocardiography (ECG) analysis is an actively developing study area which has the potential to lead to novel, artificial intelligence-based diagnostic tools in equine cardiology. As more ECG recording devices are becoming available, there is a need to ensure results are interchangeable regardless of the equipment used to record the equine ECG.
Field-applicable low-intensity exercise induces bronchodilation in horses with severe asthma
Mainguy-Seers S, Grondin SM and Lavoie JP
Airway dysfunction in severe equine asthma (SEA) often results in early retirement or euthanasia of affected horses. Exercise-induced bronchodilation occurs in horses with SEA after intense treadmill exercise, but the effects of a lighter, field-applicable, training regimen remain largely unexplored.
Beyond nocardioform: Transcriptionally active microbes and host responses in equine mucoid placentitis
van Heule M, Verstraete M, Norris JK, Graniczkowsa KB, Scoggin KE, Ali HE, Ball BA, De Spiegelaere W, Daels P, Weimer BC and Dini P
Nocardioform placentitis (NP) is an understudied form of equine placentitis historically attributed to nocardioform bacteria, yet it remains uncertain whether these organisms are the sole pathogens involved.
Agreement between veterinarians and three objective evaluation systems in naturally occurring equine lameness
McPeek JL, Menarim B, Sponseller B, McClendon M, Adam EN, Adams AA, Slone S and Page AE
Subjective lameness evaluations are critical components of equine musculoskeletal health assessments. Objective approaches can supplement diagnosis and may be preferred for specific cases and scientific purposes.
