Synovitis and/or sepsis at 5 days post-admission and involvement of Staphylococcus spp. decreases long-term athletic function. Methods: Retrospective study. Methods: Records over 4 years of adult horses with synovial sepsis were reviewed. A two-tailed Fisher's exact test, Mann-Whitney U test or t-test was used to examine whether v...
The goal of this work was the development of suitable (real-time) RT-PCR techniques for fast and sensitive diagnosis of EAV and for molecular-epidemiological characterisation of viral strains, as an alternative to virus isolation. To this purpose two conventional RT-PCR methods and one real-time RT-PCR were adapted to detect the broadest possible spectrum of viral strains. Several dilutions with Bucyrus strain showed a 100-fold higher sensitivity of real-time RT-PCR and heminested RT-PCR compared to simple RT-PCR. Making use of 11 cell culture supernatants of different EAV isolates and 7 semen...
Ferreira CMC, Simões BD, Marques EAS, Carbas RJC, da Silva LFM.Despite technological advancements in various industries, the equine sector still relies on old methods like horseshoeing. Although traditional, the industry is dynamic and well-funded. Therefore, there is a need to modernize these methods with more reliable and less invasive solutions for attaching horseshoes to horse hooves. There are currently several commercial adhesive solutions in the market specifically tailored to this application. In this work, the mechanical properties of two acrylic adhesives were characterized under quasi-static conditions. In the characterization process, tensile,...
Fritz SA, Charnas S, Ensley S.Blue green algae cyanotoxins have become increasingly more prevalent due to environmental, industrial, and agricultural changes that promote their growth into harmful algal blooms. Animals are usually exposed via water used for drinking or bathing, though specific cases related to equines are very limited. The toxic dose for horses has not been determined, and currently only experimental data in other animals can be relied upon to aid in case interpretation and treatment. Treatment is mostly limited to supportive care, and preventative control methods to limit exposures are more likely to aid ...
Fowler MA.In 1853, Rosa Bonheur first exhibited what would become her most widely celebrated work: . Although the work's modern setting and animal-focused subject matter do not obviously characterize it as an instance of classical reception, the artist claimed that it was inspired by the Parthenon frieze. A significant amount of feminist and queer scholarship has been dedicated to Rosa Bonheur's life, career, and art practices, all of which reveal the complex ways in which the artist negotiated the gender norms of 19th-century France. These ranged from her decision never to marry, instead living in hous...

Knowing how climatic and biotic factors affect sugar content in grasses is important for decision-making by those involved in the management of equines. Objective: (1) To characterise equine owners' knowledge and perceptions of the factors affecting sugar content in grasses to inform in the management of grasses and equines. (2) To identify associations between pre-existing horse-related experience and level of knowledge about equine nutrition and health conditions. Methods: A questionnaire was ...
Daniels S, Martin S, Harris P, Moore-Colyer M.The in vitro gas production system (GPS), developed to estimate degradation of ruminant feedstuffs, has been adapted for equine use. This study aimed to characterise the bacterial community profile and metabolome of donor faeces and faecal inoculum within the GPS when fermenting the same diet as faecal donors. Six Welsh ponies on identical diets were faecal donors with samples collected for microbiome profiling and system inoculation. Gas production (manual pressure transducer technique) was performed for 156 h with 2 replicate bottles from each donor harvested at 8,20,28 and 36 h. Faecal an...
Chwirot A, Niedźwiedź A, Stygar D, Siwińska N, Paszkowska M, Niżański W, Napierkowska S, Migdał P, Kublicka A, Marynowska M, Matczuk A....This study investigated the presence of antibodies to human adenovirus type 36 (HAdV-D36) in horses with different metabolic statuses, including normal, overweight, and those diagnosed with equine metabolic syndrome (EMS). A total of 151 serum samples were tested, of which 47.6% were positive for anti-HAdV-D36 antibodies. Although the horses were confirmed to be susceptible to HAdV-D36 infection, there was no significant correlation between infection and blood glucose or cholesterol levels. However, the triglyceride levels showed significant differences-they were particularly elevated in the s...

Buckman PN, Brinker BA, Kapeller LE, Komáromy AM.To determine the accuracy of the EYEMATE-SC suprachoroidal tracer for telemetric tonometry in canine and equine globes. Methods: The EYEMATE-SC sensor (7.8 mm × 3.8 mm × 1 mm) was implanted in the suprachoroidal space of four freshly enucleated normal canine and two normal equine eyes. The anterior chambers were cannulated and connected to a reservoir of Plasma-Lyte A and a manometer. Starting at a manometric IOP of 5 mmHg, the pressure was progressively increased to 80 mmHg by raising the reservoir. At each setpoint (5, 10, 15, 20, 25, 30, 35, 40, 50, 60, 70, and 80 mmHg), t...
Sousa JA, Miranda LM, Coutinho DJB, Costa TF, Costa SP, Freitas ÚS, Costa FB, Machado RZ, Nogueira RMS, Costa APD.The hemoprotozoan Trypanosoma evansi is a parasite that infects mammals, causing an infection known as trypanosomiasis. There is no report of T. evansi in horses in the State of Maranhão, highlighting the need to assess exposure and infection by the parasite and generate data for its monitoring. The objectives of this study were to identify T. evansi in blood samples from horses, investigate its occurrence in horses in this region, and analyze the associated risk factors. Three hundred blood samples were collected for parasitological (blood smear), serological (indirect enzyme-linked immunoso...
Legg KA, Cochrane DJ, Gee EK, Chin YY, Rogers CW.Thoroughbred race-riding requires jockeys to attenuate horse movement and maintain postural stability whilst galloping at high speeds. This study aimed to investigate the head movement of jockeys in relation to race-riding experience. Accelerometer and heart rate data were collected from twelve apprentice and two senior jockeys during 85 exercise rides and 82 trial rides. Mean head displacements were determined for each jockey by double integrating the filtered acceleration data. A mixed effect multivariable linear regression model was used to investigate the relationship between jockey experi...
Kloster H, Stormo C, Haaland AH, Stuen S, Kjelland V. ticks play a crucial role as carriers of diseases, transmitting pathogens to vertebrate hosts, including horses. This study aimed to investigate the seroprevalence of IgG antibodies against sensu lato (s. l.), , and tick-borne encephalitis virus (TBE-virus) in equine sera collected in southern Norway. In total, sera from 331 horses stabled in four counties (Agder, Vestfold and Telemark, Vestland, and Viken) were analyzed by immunoblot. In total, 66% of the horses were IgG-seropositive for antibodies against one or multiple tick-borne pathogens. The highest seroprevalence was detected against...
Souto PC, Santos MR, Orozco AMO, Bento LD, Ramirez-Lopez CJ, Girardi FM, Machado JCA, de Oliveira LL, da Fonseca LA.We aimed to develop a species-specific ELISA for qualitatively and quantitatively determining serum amyloid A (SAA) in horses. Current methods for measuring SAA in horses utilize ELISA or immunoturbidimetric tests designed for human SAA, which are not specific to horses. Mice and rabbits were used to generate polyclonal antibodies against equine SAA. The study examined serum samples from 32 horses with acute inflammatory disease (SG) and 25 clinically healthy horses. Furthermore, the SAAeq kinetics were observed in three horses from the SG group at three different timepoints. The SAA-ELISA est...
Hellige M, Geburek F.A number of indications exist that necessitate radiologic examination of the equine cervical spine. Different neurologic and pain-associated clinical signs within the scope of lameness or poor performance may be associated to pathologies of the cervical spine. Moreover, the number of requests for radiographic examinations of the cervical spine, for example as part of the pre-purchase examination, has increased significantly in recent years. However, the interpretation of radiographs represents a challenge, particularly in the case of clinically sound horses, as it often necessitates the resolu...

Germann JA, O'Sullivan TL, Greer AL, Spence KL.This study aimed to describe implementation of biosecurity practices by Ontario horse owners and investigate whether biosecurity implementation was associated with horse-owner demographic characteristics and personality traits. Unassigned: A cross-sectional questionnaire was administered to a convenience sample of horse owners in Ontario to collect data on demographics, personality traits, risk comprehension, and biosecurity practices. Hierarchical cluster analysis was used to identify clusters of participants with shared personality traits, and univariable associations between clusters and de...
Wang B, Duan W, Zhao J, Bai D.Once a mare experiences parturition abnormalities, the outcome between a live foal and a stillborn can change rapidly. Automated detection of mare parturition and timely human intervention is crucial to reducing risks during mare and foal parturition. This paper addresses the challenges of manual monitoring of parturition in large-scale equine facilities due to the unpredictability of mare parturition timing, proposing an algorithm for detecting mare parturition through a balanced multi-scale feature fusion based on an improved Libra RCNN. Initially, a ResNet101 backbone network incorporating ...
Chapman M, Fenner K, Thomas MJW.Equestrianism has an opportunity to learn lessons relating to safer human-horse interactions from those who no longer have a voice, by drawing data from the investigation of horse-related human fatalities and participating in accident analysis. Many human-horse related injuries and fatalities are not examined in equestrianism for the purpose of developing safer future risk mitigation practice, often due to the philosophy that horse sport is simply dangerous. This study analysed data from the Australian National Coronial Information System (NCIS) relating to fatalities involving human-horse int...
Dufourni A, Demeyere M, Vera L, van Loon G, Decloedt A.This study aimed to compare two-dimensional, M-mode, color, pulsed-wave Doppler (PWD) and continuous-wave Doppler (CWD) echocardiography, and PWD ultrasonography of the caudal common carotid artery (CCA) in horses with aortic regurgitation (AR). Methods: Warmblood horses without (n = 20) and with mild, moderate, and severe AR (n = 60) were included in the study.

Groups were compared using analysis of varianc...
Firshman AM, Valberg SJ.Type 1 Polysaccharide Storage Myopathy (PSSM1) is an autosomal dominant glycogen storage disorder affecting more than 20 breeds of horses that can present with a variety of signs, including exertional rhabdomyolysis (ER). It is diagnosed by genetic testing or muscle biopsies containing muscle fibers with abnormal amylase-resistant polysaccharide. Type 2 PSSM has recently been subdivided. PSSM2-ER is a glycogen storage disorder identified in Quarter Horses that causes ER and is diagnosed by muscle biopsy as its genetic basis is unknown. Both PSSM1 and PSSM2-ER respond well to a low nonstructura...
Brady FA, McDonell J.This case study aims to problematise concepts of equine and human co-relational agency in the context of 'mis-re-presentations' in the Australian media of harms experienced by the Anglo Arab stallion, Cambridge, following his development of laminitis and his consequent confinement at a leading national Equestrian centre. Autoethnographic narrative is used to retrospectively and selectively narrate the evolving relationship between Cambridge and his owners, farrier, and treating veterinarians within the dominant housing and veterinary practices and welfare paradigms in equestrian culture of 199...
Błaszczak A, Stefaniuk-Szmukier M, Długosz B, Musiał AD, Olczak K, Ropka-Molik K. The Hucul horse breed formed in the region of the Eastern Carpathians, likely through the natural crossbreeding of oriental horses. After World War II, their population significantly decreased, leading to the breeding being based on only 14 female lines, whose founders often had unknown origins. To preserve the breed's unique characteristics, it is now part of a Genetic Resources Conservation Program, which prioritizes the maintenance of genetic diversity. This study aims to clarify the maternal relatedness of founder mares and assess genetic diversity using mitochondrial DNA (mtDNA). The hy...
Brandenberger O, Kalinovskiy A, Körner J, Genn H, Burger R, Leser S.The use of Bio-Electro-Magnetic-Energy-Regulation (BEMER) therapy during general anesthesia has not previously been reported in horses. This randomized, investigator-blinded, placebo-controlled trial evaluates equine cardiopulmonary function and recovery quality after BEMER therapy application for 15 min in 100 horses during general anesthesia using isoflurane for pars-plana vitrectomy surgery as treatment for recurrent uveitis. Visually identical blankets were used in the two groups (1:1 ratio), one with a functional BEMER module and the other with a placebo module. Arterial blood pressure, b...
Charbonnel A, Lavoie JP, Juette T, St-Sauveur VG, Denis S, Gagnon CA, Leclère M.The control of equine respiratory infections is a biosecurity challenge. Respiratory viruses are often rapidly detected using quantitative polymerase chain reaction (qPCR) on nasal swabs. In the past, some laboratories developed handmade techniques to increase the amount of nasal secretions collected, without comparing them with nasal swabs when qPCR replaced the use of viral culture. The objectives of this study were to compare nasal swabs and handmade foam cubes for i) the detection of a common equine herpesvirus (EHV-5) by qPCR, and ii) their tolerability. Forty-five polyester swabs and foa...
Chapman M, Fenner K, Thomas MJW, Thompson K.With the growth of the equestrian industry, risk exposure and the obligation to maintain the health, safety, and welfare of humans and horses remain front and centre. As there has been no apparent reduction in non-fatal human horse-related injuries, we asked industry stakeholders to discuss their current management and risk mitigation practices and highlight potential barriers to improving these processes. Semi-structured interviews were conducted with 20 stakeholders from Australian equestrian work- ( = 9) and non-work- ( = 11) related organisations to determine the potential benefits and fea...
Suganuma K, Fujita G, Macalanda AMC, Regilme MAF, Izumida H, Inoue N, Acosta TJ.Horseflies are pests that cause discomfort from blood-sucking and disease transmission, and economic losses in the equine industry. This study evaluated the efficacy of horsecloth impregnated with icaridin in reducing horsefly attacks and deterring horseflies. Repellent activities were evaluated under three conditions: treatment 1 (no horsecloth), 2 (horsecloth without icaridin), and 3 (horsecloth impregnated with icaridin), using three native Hokkaido horses (Dosanko) and three mixed-breed horses (Dosanko and Haflinger) in July 2023 at a riding horse club in Hokkaido, Japan. Treatment 3 signi...
Merkies K, Trudel K.Horses employ a range of subtle to overt behaviours to communicate their current affective state. Humans who are more cognisant of their own bodily sensations may be more attuned to recognising affective states in horses () thereby promoting positive human-horse interactions. This study investigated human ability to categorise human-horse interactions depicted in media relative to equine behaviour experts and compared participant scores to their level of interoception. Using an online survey, participants (n = 534) categorised 31 photographs and videos as (overt) positive, likely (subtle) posi...
Neville EK, Neville CC, Hicks H.The size, strength, and unpredictability of horses, makes any interaction a potential situation for minor to severe injury. Despite this, horses continue to be popular for work and recreational activities. There have been five recent Australian publications that have examined various aspects of horse-related trauma, but none have been conducted in regional New South Wales (NSW). This study aims to report on the pattern of horse-related trauma that met the Institute of Trauma Injury Management's (ITIM) Trauma Registry criteria for people who presented to the emergency department at a regional N...
Vázquez Bringas FJ, Porcar LB, Franco SF, Martinez CM, Lasheras AR, Moraiz AV.Transrectal palpation (TP) is a basic skill in equine practice. Traditional TP learning methods include instructor-assisted TP in live animals, but this approach presents animal welfare concerns, especially when it needs to be used with large numbers of students. The main objective of this study is to compare two learning methods of TP: traditional methodology with live horses (LH) and alternative methodology using a cadaver with its flanks dissected (CDV). Twenty students with no previous equine TP experience were randomly assigned to two groups: LH ( = 10) and CDV ( = 10). Both groups receiv...
Costa Kamura BD, Albertino LG, Cavallari RR, Queiroz de Souza L, Rodrigues LT, Barros de Sousa Pereira I, Rocha NS, Takahira RK, Briscola Pereira WA....Africanized crossbred bees (Apis mellifera) originated in Brazil in 1957, and since then, the number of accidents involving humans and animals has significantly increased. Although they are considered clinical emergencies, there are few reports describing the clinical and pathological aspects of bee envenomation in horses. In this context, this report aims to describe the clinical and pathological features of bee toxicity after massive bee envenomation in three horses. The horses were referred to the veterinary hospital the day following the attack, and after clinical and laboratory examinatio...
