Veterinary care also involves diagnostic procedures, surgical interventions, and therapeutic treatments tailored to the specific needs of horses. This page gathers peer-reviewed research studies and scholarly articles that explore various aspects of equine veterinary care, including advancements in diagnostic techniques, treatment protocols, and health management strategies to support the well-being and performance of horses.
Analysis of risk factors associated with antibiotic-resistant Escherichia coli. Antimicrobial-resistant bacteria represent a major threat to human and animal health. We compared equine fecal samples (n=264) from 138 horses from hospital and nonhospital (livery stable and riding school) premises in North West England to determine the prevalence of Escherichia coli, Salmonella, and Campylobacter and rates of antimicrobial-resistant E. coli strains. Campylobacter jejuni was detected only in hospitalized horses (1.1%), and no Salmonella was identified. Data analysis of the horses' management and veterinary treatments (Tx) identified risk factors associated with shedding of an...
A method to minimise error in 2D-DLT reconstruction of non-planar markers filmed with a moving camera. This article describes a method that allows estimating, with the 2D version of the direct linear transformation (DLT), the actual 2D coordinates of a point when the latter is not strictly in the calibration plane. Markers placed in vertical line, above, below and in the centre of a horizontal calibration plane were filmed by a moving camera. Without correction, strong errors (up to 64.5%) were noticed for markers out of the calibration plane. After correction, calculated coordinates were consistent with actual values (error < 0.55%). The method was then applied to slip distance measuremen...

Methods: Prospective clinical trial. Methods: 21 horses with DIT or TMT joint-associated hind limb lameness and 5 nonlame horses. Methods: 11 horses (group 1) underwent lameness, force-plate, and radiographic examinations; following intra-articular analgesia, lameness and force-plate examinations were repeated. Nonlame horses were used for force-plate data acquisition only. Following localization of lameness to the DIT ...
Ileal impaction in 245 horses: 1995-2007. The objective of this study was to identify parameters that would assist in determining the probability of a successful outcome with medical management versus surgical intervention in horses with ileal impaction. Medical records of 245 horses admitted for ileal impaction were reviewed and placed into 2 groups: medical (med) and surgical (sx) treatment. Persistence of abdominal pain, gastric reflux, frequency of analgesic administration, and 1-year survival were evaluated. There were no differences in signalment, abdominal pain, or heart rate among groups; however, significantly more sx horses ...
Costochondral junction osteomyelitis in 3 septic foals. The costochondral junction constitutes a potential site of infection in septic foals and it could be favored by thoracic trauma. Standard radiographs and ultrasonography are useful tools for diagnosis of this condition and ultrasound-guided needle aspiration could permit the definitive confirmation of infection. La jonction costochondrale constitue un site potentiel d’infection chez le poulain septicémique et le développement de l’infection pourrait être favorisée par un traumatisme costal. Les radiographies standards et l’échographie sont des aides diagnostiques et l’aspiration ...
Case report: squamous cell carcinoma of the urinary bladder in a horse. A 14-year-old Hanoverian gelding was evaluated after a 10-week history of occasional straining during urination and dark red urine production after exercise. Physical examination findings were within normal limits. After 2 weeks of clinical signs, ultrasonography had found no abnormalities in the kidneys or bladder. A freely voided urine sample revealed an elevated protein concentration (500 mg/dL; reference range: <100 mg/dL) and few red blood cells. Vitamin C supplementation was suggested to acidify the urine, as was provision of a salt block to encourage water intake.
Sacroiliac injuries in horses. This article reviews the pathology, diagnosis, and treatment of sacroiliac joint injuries. These injuries can be acute or chronic and can involve soft tissue structures surrounding the joint or the bony structures of the joint. The several diagnostic modalities for sacroiliac injuries vary in usefulness and accessibility. Treatment of sacroiliac problems is usually supportive and nonspecific and includes the use of antiinflammatory medications and an appropriate exercise regimen. The prognosis depends on the cause, but severe injuries can limit a horse's future athletic activity.
Prevalence and intensity of gastro-intestinal helminths in horses in the Sudano-Guinean climatic zone of Cameroon. It is important to understand the biology and health impact of parasites affecting horses in the Western highlands of Cameroon. Objective: to evaluate the prevalence and intensity of infection of gastrointestinal helminths in these animals. Methods: A total of 894 horses (367 males and 527 females), and aged ≤1 to ≥7 years old were examined. A parasitological investigation of faeces was carried out using two techniques: concentration method of Full Born Willis (flotation in saturated solution of sodium chloride) and Mc Master Technique. Conclusions: From the results the overall prevalence ...
Examination of the depth of the equine hard palate. Equine behavioral problems and loss of optimum performance have been associated with musculoskeletal injury and, more recently, dental disease. Injuries to a horse's tongue and bars of the mandible due to bitting have been documented. However, another point of contact of the bit, the hard palate, has thus far been virtually ignored. The objective of the study was to determine if there was a significant range associated with the depth of the equine hard palate and if this range was associated with a certain breed, age, or sex of the horse. Oral examinations were performed on 52 horses and a mea...
Essential considerations for equine oral examination, diagnosis, and treatment. Equine dentistry should no longer be thought of as art over science. To be an effective equine dental clinician requires considerable investment in knowledge beyond the basic veterinary degree. It requires current scientific dental knowledge and adherence to the fundamental principles of medicine, dentistry, and surgery. Knowledge and principles will provide clinicians with the necessary information to make more evidence-based decisions as the scientific literature continues to evolve. Diagnosis and therapy should be seen as journeys with a destination, keeping in mind the values of the Hippoc...
Development and laboratory evaluation of two lateral flow devices for the detection of vesicular stomatitis virus in clinical samples. Two lateral flow devices (LFD) for the detection of vesicular stomatitis (VS) virus (VSV), types Indiana (VSV-IND) and New Jersey (VSV-NJ) were developed using monoclonal antibodies C1 and F25VSVNJ-45 to the respective VSV serotypes. The performance of the LFDs was evaluated in the laboratory on suspensions of vesicular epithelia and cell culture passage derived supernatants of VSV. The collection of test samples included 105 positive for VSV-IND (92 vesicular epithelial suspensions and 13 cell culture antigens; encompassing 93 samples of subtype 1 [VSV-IND-1], 9 of subtype 2 [VSV-IND-2] and 3...
The danger of having all your eggs in one basket–winter crash of the re-introduced Przewalski’s horses in the Mongolian Gobi. Large mammals re-introduced into harsh and unpredictable environments are vulnerable to stochastic effects, particularly in times of global climate change. The Mongolian Gobi is home to several rare large ungulates such as re-introduced Przewalski's horses (Equus ferus przewalskii) and Asiatic wild asses (Equus hemionus), but also to a millennium-old semi-nomadic livestock herding culture.The Gobi is prone to large inter-annual environmental fluctuations, but the winter 2009/2010 was particularly severe. Millions of livestock died and the Przewalski's horse population in the Gobi crashed. We u...
Computed tomographic appearance of equine sinonasal neoplasia. The computed tomography (CT) features of tumors involving the nasal cavity and/or paranasal sinuses of 15 horses were reviewed. The 15 tumors included five neuroendocrine tumors/neuroblastomas, two undifferentiated carcinomas, two myxosarcomas, and one each of nasal adenocarcinoma, hemangiosarcoma, chondroblastic osteosarcoma, anaplastic sarcoma, myxoma, and ossifying fibroma. All tumors except the ossifying fibroma were iso- or hypoattenuating relative to masseter muscle. Thirteen of the fifteen tumors exhibited moderate or marked osteolysis of adjacent cortical bone and 14/15 were characteri...
Heritability estimates for racing performance in Japanese Thoroughbred racehorses using linear and non-linear model analyses. This study evaluated the differences between linear and non-linear modelled heritability estimates of racing performance based on lifetime earnings (LE) and lifetime ranking (LR) in Japanese Thoroughbred racehorses. The heritability estimate (h(2) = 0.25) obtained from a non-linear model based on formal Japan Racing Association ranking was much higher than that obtained from a linear model based on the original trait phenotype (h(2) = 0.11). The linear models showed slightly higher heritability estimates under the trait categorizations than under the original phenotypes, while the non-linear c...
Human-animal relationships: from daily life to animal-assisted therapies. Humans have a long history of relationship with domestic animals and nowadays pets often act as "social substitutes" through bonding. There is some evidence that pet presence at home may induce well being in people and the development of social skills in children. Animal assisted therapies aim at developing these skills in patients on the basis of human animal interactions. Experimental data obtained on animal models suggest that this is indeed a promising line. There is however a lack of clear scientific data that would help defines what the most appropriate procedures or species may be. Impr...
A clinical case of dourine in an outbreak in Italy. In May 2011, dourine was reported in Italy following the declaration of a positive result observed in a stallion undergoing routine testing for stud purposes. Clinical signs, anatomo-histopathological findings and laboratory results that resulted in the confirmation of diagnosis of dourine in a clinically affected mare, which was the likely source of infection in the stallion, are described.
Veterinary Vaccines and Their Importance to Animal Health and Public Health. Veterinary vaccines have had, and continue to have, a major role in protecting animal health and public health, reducing animal suffering, enabling efficient production of food animals to feed the burgeoning human population, and greatly reducing the need for antibiotics to treat food and companion animals. Prominent examples include rabies vaccines and rinderpest vaccines. Rabies vaccines for domestic animals and wildlife have nearly eliminated human rabies in developed countries. Thanks to the Global Rinderpest Eradication Program which involves vaccination, trade restrictions, and surveilla...
Effect of embryo age and recipient asynchrony on pregnancy rates in a commercial equine embryo transfer program. In the present study, 809 uterine flushes and 454 embryo transfers performed in mares over a 4-yr interval were examined to evaluate the effects of: (1) the day of embryo collection on recovery rates; (2) the degree of synchrony between donor and recipient mares on pregnancy rates; (3) the recipient day post ovulation on pregnancy rates; and (4) the age of the embryo at recovery on pregnancy rates at 60 days. Uterine flushes were performed on Days 6, 7, 8, 9, and 10 (Day 0 = ovulation) and embryos were transferred to recipients with degrees of synchrony varying between +1 to -6 (recipient ovul...
Association between circulating angiotensin-converting enzyme and exercise-induced pulmonary haemorrhage in Thoroughbred racehorses. Exercise-induced pulmonary haemorrhage has an impact on racehorse performance. Although endoscopic diagnosis (with or without the aid of bronchoalveolar lavage) is considered to be the standard diagnostic method for this condition, the use of biomarkers that could aid in quantifying risk and severity of the condition would represent an advance in equine sport medicine. This preliminary research investigated the use of angiotensin-converting enzyme (ACE) activity in plasma of racehorses and demonstrated that ACE activity is increased in horses with higher degrees of haemorrhage and is a promisi...
Distal aortic aneurysm presumed to be secondary to an infected umbilical artery in a foal. A 3-month-old female Warmblood foal was presented after displaying signs of colic with pyrexia for 5 days. Results: The foal continued to show signs of colic, frequently passed urine, and was pyrexic with an elevated white blood cell count. The umbilical stalk was thickened but there was no evidence of purulent material. Exploratory laparotomy revealed an enlarged left umbilical artery remnant tightly adhered to the bladder wall. The left umbilical artery continued to an aneurysm involving the distal aorta. The foal was subject to euthanasia and post-mortem examination confirmed a spherical ao...
Three-dimensional ultrasound imaging of the equine fetus. The objective was to assess the optimal procedure for real-time, three-dimensional (3D) ultrasound (US) imaging for assessing the equine fetus during the first half of gestation and the possibility of using 3D US imaging of the equine fetus in clinical applications. Seventeen pregnant mares were examined by 3D US between Days 35 and 180 of gestation. Abdominal and endo-vaginal real-time 3D transducers used in human medicine were used for transrectal and transvaginal examinations, respectively. Images were recorded by both 3D stationary and real-time movies. In a comparison of four methods, tra...
Lactate production and measurement in critically ill horses. Blood lactate concentration can be easily measured by practitioners using inexpensive point-of-care meters. Anaerobic tissue metabolism resulting from inadequate oxygen delivery (DO2) is the most important cause of an increase in blood lactate concentration in equine patients. However,hyperlactatemia also occurs under conditions of apparently adequate DO2, usually in association with sepsis and an intense inflammatory reaction. Numerous mechanisms have been proposed for aerobic hyperlactatemia, including increased Na+/K+-ATPase activity in response to inflammatory mediators; inhibition of pyru...
Cytokines tumor necrosis factor-α and interferon-γ participate in modulation of the equine corpus luteum as autocrine and paracrine factors. Knowledge on the regulation of corpus luteum (CL) function in the mare is scarce. In this study, the presence of cytokines tumor necrosis factor alpha (TNF) and interferon gamma (IFNG), and their receptors (TNFRI, TNFRII and IFNRI), was investigated in equine CL throughout the luteal phase. The effects of TNF and IFNG on secretory function and viability of luteal cells were defined in vitro. Cytokine ligands and receptors were present in steroidogenic and endothelial cells. Protein expression for TNF was greater in mid-phase and regressing CL, while TNFRI was increased in regressing CL and TNF...
Conservative management of a transverse fracture of the distal phalanx in a Quarter Horse. A 7-year-old Quarter Horse gelding was evaluated because of sudden onset of severe left forelimb lameness of 4 days' duration. Results: Clinical evaluation and diagnostic perineural analgesia localized the lameness to the distal portion of the left forelimb. Radiography revealed a transverse fracture of the distal phalanx of the left forelimb. Results: The horse was treated conservatively with stall rest and stabilization of the hoof with fiberglass cast material and an elevated heel support. These treatments improved the lameness considerably. Over the following 4 months, the horse was exerci...
