Robinson NE, Derksen FJ, Olszewski MA, Buechner-Maxwell VA.Present evidence suggests that chronic obstructive pulmonary disease (COPD) of horses is a delayed hypersensitivity response to inhaled antigens, particularly the thermophilic moulds and actinomycetes that grow in damp hay. Within several hours of exposing COPD-susceptible horses to such hay, neutrophils invade the lung and accumulate in the lumens of airways, particularly bronchioles. The inflammatory response is accompanied by increased levels of histamine in bronchoalveolar lavage fluid, increased plasma levels of the inflammatory mediators thromboxane and 15-hydroxyeicosatetraenoic acid (1...
Oelrichs PB, Calanasan CA, MacLeod JK, Seawright AA, Ng JC.Regular ingestion of Eupatorium adenophorum [Ageratina adenophora (Spreng.)] or Crofton weed causes chronic pulmonary disease in horses mainly in Australia, New Zealand, and the Himalayas. The disease is characterized by pulmonary interstitial fibrosis, emphysema, alveolar epithelisation and reduced tolerance to exercise. Horses apparently are the only animals affected and there are numerous reports of farms losing all their horses. The disorder was produced experimentally in horse feeding trials, and it was shown that characteristic lesions occurred in the lungs. In studies with laboratory an...
Lees P, McKellar Q, May SA, Ludwig B.The pharmacokinetics and pharmacodynamics of the nonsteroidal anti-inflammatory drug (NSAID) carprofen have been evaluated in 6 horses using a model of acute non-immune inflammation. Following intravenous administration of 0.7 mg racemic carprofen/kg bwt, mean values for pharmacokinetic parameters were 18.1 h (elimination half-life); 0.25 l/kg (volume of distribution, Vd[area]); 58.9 ml/min (clearance); and 57.9 micrograms/ml.h (area under plasma concentration time curve). Mean exudate:plasma concentration ratios exceeded 1.0 at all sampling times between 2 and 48 h. Swelling at the site of ac...
The Horserace Betting Levy Board formulates codes of practice for the control of contagious equine metritis and other equine bacterial venereal diseases, and equine viral arteritis and equid herpesvirus 1. This year's codes have just been published and the code of practice for EVA, reproduced below, has been substantially amended following the recent outbreak in the UK. The code is intended for use by veterinary surgeons and breeders of thoroughbred and non-thoroughbred horses. The HBLB states that its recommendations represent the minimum measures necessary to monitor for the presence of equi...
House JA.AHS is a noncontagious vector-borne disease of Equidae caused by Orbiviruses. Species susceptibility in decreasing order is horses, mules, donkeys, and zebras. The main vectors of AHS are culicoides. The disease is endemic in sub-Saharan Africa, but epizootics have occurred outside of this area on several occasions. The most recent outbreaks outside of the endemic area were in Spain, Morocco, and Portugal between 1987 and 1990. AHS causes mortality up to 95% and is classically divided into four clinical forms: the pulmonary, cardiac, mixed, and horse fever forms. Pathologic changes are subcuta...
Santschi EM, Slone DE, Frank WM.During a 28 month period, 82 horses with clinical signs of abdominal pain were examined for left dorsal displacement of the large colon (LDDLC) using percutaneous ultrasound. Left dorsal displacement of the large colon was diagnosed when a gas echo dorsal to the spleen obliterated the dorsal splenic border, or when the colon was observed lateral to the spleen. In 42 horses, ultrasound confirmed a diagnosis of LDDLC and 40 horses had no evidence of LDDLC. There were five false negative results and no false positives. In four horses with LDDLC, the colon was displaced between the spleen and body...
van der Kolk JH, van der Wijden MW, Jongejan F.Equine granulocytic ehrlichiosis (EGE) has been observed in the U.S.A., Brazil, Germany, Sweden, Switzerland and possibly in Great Britain. The causative agent is rickettsia Ehrlichia equi, identified for the first time in 1969. The clinical features of the disease are anorexia, fever, depression, (limb) oedema, icterus, ataxia, petechiae and orchitis. Hematologic changes are leukopenia, thrombocytopenia, anemia and cytoplasmic inclusion bodies in the neutrophils and eosinophils. Vasculitis may be observed at autopsy. Following a positive hematological diagnosis (Giemsa stained blood smear) of...
Benoit P, Barrey E, Regnault JC, Brochet JL.The purpose of this study was to compare the damping effect of 16 types of shoeing by measuring hoof acceleration parameters on two trotting horses. At impact, maximal deceleration had extreme values such as 188 m/s2 (+/- 55) for the most damping combination (p < 0.01) and 746 m/s2 (+/- 14) for the steel shoe (mean = 551 m/s2 +/- 125). After the shock, the hoof was exposed to a mean vibrating acceleration at 418 Hz (+/- 84) which was progressively damped in 37.3 ms (+/- 10.5). According to these results, the damping ability of different farriery products significantly reduces (p < 0.05) shocks...
Habel RE, Budras KD.Analyses of the fibers in the prepubic tendon of the horse and ruminants have shown that it is composed of the crossed and uncrossed tendons of origin of the pectineus muscles, the pelvic tendons of the rectus and obliquus abdominis muscles, and the tendons of origin of the cranial parts of the gracilis muscles. Pelvic attachments of the linea alba and the yellow abdominal tunic are incorporated in it. It is not a transverse ligament, and it is not homologous to the human superior (cranial) pubic ligament. The dog differs in 4 respects: (1) the pectineus tendons do not cross, but each originat...
Evans DR.In reporting the results of the medical examination for purchase, the veterinarian should not make an evaluation as to the animal's suitability for the purpose intended but should rather reveal all of the abnormal and undesirable findings and give his or her opinion as to the effect these findings will have on the performance of the horse for the purpose intended. A written report should be provided, and any factors that have had an influence on the opinion rendered should be a part of the report. A record of all procedures performed, the results of these procedures, the names and addresses of...
Ball BA, Wilker C, Daels PF, Burns PJ.Administration of progesterone in poly(d-,l-lactide) microspheres was used to maintain pregnancy in mares after luteolysis was induced by treatment with prostaglandin F2 alpha at day 14 of pregnancy. Mares were given vehicle only (control, n = 6) or 0.75 g (n = 7), 1.5 g (n = 8), or 2.25 g (n = 5) of microencapsulated progesterone at days 12 and 22 of pregnancy. Serum progesterone concentrations were determined daily, and pregnancy was evaluated by transrectal ultrasonography on alternate days. Significantly (P less than 0.05) more mares given 1.5 or 2.25 g of progesterone (6 of 8 and 4 of 5 m...
Watson TD, Murphy D, Love S.The background, clinical signs, blood biochemistry and management of 18 cases of equine hyperlipaemia are described. Eleven of the animals were Shetland ponies, four were Welsh mountain ponies or their crosses, one was a fell pony and two were riding ponies of mixed breeding. Their average age was nine years. Fourteen of the cases were mares, of which nine were in foal and two were lactating; the remainder were geldings. Underlying or concurrent diseases were identified in only six animals, but in one other animal the hyperlipaemia appeared to have been precipitated by stress, and in another b...
Bickhardt K, Carstensen CA.The Reflotron-CK test was evaluated with blood samples of healthy and diseased pigs, sheep, cattle, horses and dogs in relation to the standard CK-NAC test (UV-method). The precision within the series on the day of blood sampling was better than VK = 7.5% (coefficient of variation) with both methods. The day to day precision was estimated by using deep frozen plasma and was in the same order of magnitude with the Reflotron-CK and the UV-method (CV less than 10%). While fresh whole blood of sheep, cattle, horses and dogs respectively should be applied directly onto the dry reagent carrier with ...
Gift LJ, DeBowes RM, Clem MF, Rashmir-Raven A, Nyrop KA.The medical records of 20 horses admitted to the veterinary medical center with a diagnosis of brachygnathia over a 10-year period (1979 to 1989) were reviewed. The study included 18 foals and 2 adult horses. Males were affected 5.7 times more frequently than females. The amount of disparity between the mandible and premaxilla varied between 0.75 and 3 cm. Sixteen foals were treated surgically with the temporary application of premaxillary tension band devices. Thirteen of the 16 surgical cases were available for follow-up evaluation. All of the surgically treated animals had improved incisive...
Yovich JV, Gould DH, LeCouteur RA.The distribution and morphology of fibrous astrocytes in the cervical spinal cord of normal horses and horses with chronic compressive myelopathy were demonstrated using immunohistochemical staining for glial fibrillary acidic protein. In the spinal cord from normal horses, astrocytes with stellate cell bodies and short processes were irregularly distributed in grey matter. In the white matter, their cell bodies were small and angular in areas adjacent to grey matter and larger and more stellate-shaped in the subpial area. Astrocyte processes were fine, and evenly distributed in a predominantl...
Sharshar A, Hammad A, Salem M, El-Sunsafty M.This study was carried out to evaluate a rectal pull-back one-stage technique, which is a modification of the one-stage Goetz technique, for treating third-degree perineal laceration or rectovestibular fistula. Methods: This study was performed on 12 mares, ten of whom suffered from third-grade perineal laceration, and two suffered from rectovestibular fistula and were included in this study.

Kuzmina TA, Königová A, Burcáková L, Syrota Y, Babják M, Várady M.Strongylids and parascarids are the most widespread equine parasites worldwide; however, up-to-date data from Slovakia remain limited. This work bridges that gap by examining the prevalence and level of gastrointestinal helminth infections in Slovak horses. In the study, 392 fecal samples from horses on 24 farms were analyzed using the McMaster method with a sensitivity of 50 eggs per gram (EPG) for detecting nematode eggs and a double-centrifugation/combined sedimentation-flotation protocol for detecting Anoplocephala spp. eggs. Information on the age and breed of horses, management condition...
Cloteau C, Delcourt V, Loup B, Chabot B, Pescher M, Susdorf E, Kaabia Z, Garcia P, Popot MA, Le Bizec B, Dervilly G, Bailly-Chouriberry L.Biomarker identification by mass spectrometry represents a key step in the workflow of nontargeted metabolomic studies. Given the complexity of the data, this step, which must be carried out by a trained specialist, is time-consuming, and the biomarkers discovered are not always identified. While this stage is not an obstacle to the development of new screening and classification tools, it is nonetheless crucial to a better understanding of the results obtained. For this reason, the aim of this study was to perform structural elucidation of candidate biomarkers, which had previously been displ...
Riahi Z, Naeini AT, Zare R.Dareshuri horses are the predominant breed in Fars Province, Iran. Although disorders affecting their maxillary cheek teeth and maxillary sinuses are relatively common, limited fundamental data are available on the dimensions and relationships of these structures at different ages. Given the significant anatomical changes in the heads of young horses as they mature, this study aimed to evaluate age-related changes in the position and anatomical relationships of individual maxillary cheek teeth within the rostral and caudal maxillary sinuses (RMS and CMS, respectively), as well as changes in th...
Olakojo TA, Akinniyi OO, Dansu EO, Adeoye AO, Adah O, Nwufoh OC, Adeoye BO, Oridupa OA, Saba AB.Dexamethasone is a common drug used in equine medicine, but when administered inappropriately, it can lead to serious health complications. There is a dearth of data on horse caregivers' knowledge, attitudes, and practices regarding dexamethasone use in Nigeria. Understanding current dexamethasone usage patterns is necessary for developing educational interventions which will then improve equine welfare. This study aimed to assess the knowledge, attitudes, and practices (KAP) of horse caregivers regarding dexamethasone use in Ibadan, Nigeria. A cross-sectional study was conducted amongst a tot...

Smith R, Perkins L, Pinchbeck G, Ireland J.The decisions made by horse owners on behalf of their animal, including decisions to involve a veterinarian, play an important role in the management of pain. This study explored horse owners' experiences to understand how they conceptualised chronic pain within the context of their horse-human relationship, what led them to seek veterinary involvement, and how veterinary interactions shaped their perceptions of pain and its management. An ethnographic approach using constructivist grounded theory methods was adopted. This paper draws upon field notes generated through 200 h of observation und...
Hain AM, Tretow M, Bienert-Zeit A.Outside of Iceland, the Icelandic horse is prone to the development of Equine Odontoclastic Tooth Resorption and Hypercementosis (EOTRH). The aim of this study was to determine the radiographic prevalence and clinical signs of EOTRH in elderly horses (≥15 years) in Iceland. The rostral oral cavity of 170 horses (aged 15-30 years) was examined clinically. In addition, husbandry and nutritional management history was recorded by use of a questionnaire. Radiographs (2-4 views) of 188 horses were evaluated, findings were categorized by numerical staging of the condition and collated with clinica...
Studzińska M, Klockiewicz M, Szczepaniak K, Demkowska-Kutrzepa M, Roczeń-Karczmarz M, Tomczuk K.The resistance of strongyles to pyrantel pamoate has been reported in publications worldwide. There is no data on its efficacy in horses in Poland. Therefore, the aim of this study was to evaluate the effectiveness of pyrantel pamoate to control strongyle invasions in young horses. The study involved horses of both sexes, aged 1 to 2 years, and was conducted in two seasons (spring and the end of summer). Feces were collected 24 hours before and 14 days after deworming, and they were then examined using McMaster's and combined sedimentation-flotation methods. Results revealed that in spring, th...
Verna M, Amitrano FN, Boeder ZJ.To assess the clinical impact of the cricoarytenoideus dorsalis (CAD) myectomy in the short- and long-term postoperative abduction grade in racehorses. Unassigned: Records from horses presented for surgical treatment of recurrent laryngeal neuropathy from January 2019 through December 2023 were divided into 2 groups: horses that received standard prosthetic laryngoplasty and horses that received a complete myectomy of the CAD (modified myectomy laryngoplasty). Outcomes were compared through endoscopic evaluation after anesthetic recovery, both short term (7 to 10 days) and long term (80 to 90 ...
Wilson KE, Davis JL.Adverse drug events (ADEs) are any harms caused by medical interventions used for treatment, prevention, or diagnosis. These events can happen due to human error or as unintended, harmful reactions to drugs when given at normal therapeutic doses. This review focuses on common ADEs associated with drugs frequently used in equine practice. Recognizing and understanding the manifestations of ADEs can help with early detection and more effective management, ultimately leading to better outcomes for equine patients. Additionally, knowledge of the potential harmful effects of drugs also aids in appr...
Pilati N, Pressanto MC, Palumbo Piccionello A, De Angelis Corvi F, Beccati F.The term overriding spinous processes (ORSPs), commonly known as "kissing spine syndrome," refers to a skeletal abnormality in horses that is characterized by the narrowing (<4 mm) of the interspinous space and touching or overlapping of the spinous processes (SPs). This condition primarily affects the mid- and caudal thoracic vertebrae; however, ORSP can also affect the lumbar SPs. In the veterinary community, kissing spine is widely recognized as a common condition in sport horses, as it is often associated with chronic back pain and contributes to poor performance. Despite its significant c...
Kozłowska N, Borowska M, Jasiński T, Wierzbicka M, Domino M.In human medicine, computer-aided diagnosis (CAD) is increasingly employed for screening, identifying, and monitoring early endoscopic signs of various diseases. However, its potential-despite proven benefits in human healthcare-remains largely underexplored in equine veterinary medicine. This study aimed to quantify endoscopic signs of pharyngeal lymphoid hyperplasia (PLH) as digital data and to assess their effectiveness in CAD of PLH in comparison and in combination with clinical data reflecting respiratory tract disease. Endoscopic images of the pharynx were collected from 70 horses clinic...
Chaimbeul SF, Rodrigues NNP, Thurston DD, Scoggin KE, Janes J, Jacobs CA, MacLeod JN, Stone AV, Menarim BC.Synovitis resolution is critical for joint homeostasis and prevents the progression of osteoarthritis (OA). Treatments like NSAIDs and intra-articular corticosteroids relieve symptoms by blocking pro-inflammatory mediators, but also impair the production of pro-resolving mediators, contributing to the likelihood of chronic synovitis. PPARγ signaling is an essential mechanism of synovitis resolution, which is decreased in OA tissues. To evaluate the potential of PPARγ agonists to promote pro-resolving pathways, equine macrophages cultured in autologous, normal, or inflamed synovial fluid ( = ...

Lugo T, Myers S, Nguyen TA.In vitro models have revolutionized our understanding of biological pathways and mechanisms, offering a viable alternative to direct patient testing. However, there is a significant lack of models for different animals, particularly equine models. This study presents a novel primary cell culture extracted from a 3-year-old horse diagnosed with multisystemic eosinophilic epitheliotropic disease. Tissue samples were collected from lymph nodes at various locations. Growth curves of extracted primary cells were analyzed and the optimal conditions were assessed. Biomarkers, such as CD31, ZO-1, CD79...
Allen TS, Johnson S.The physical stresses on equine athletes are unique and differ across various disciplines. Recognizing these differences is essential for early detection of injuries and effective management of the competition horse's health. Equine sports medicine involves specific challenges and risks that can be reduced through proper care, careful attention to technique, and a deep understanding of the demands of each sport. Proper training, regular monitoring, and sport-specific expertise are crucial in preventing injuries and ensuring optimal performance. By focusing on these aspects, veterinarians and t...
Mazur SE, Toribio RE.Complications in critically ill equine patients are often related to the underlying disease process but can also be a consequence of diagnostic and therapeutic interventions. Complications can be specific to the affected organ or body system; however, in critically ill patients, they frequently affect the vasculature, acid-base, electrolyte, and fluid balance, energy homeostasis, and coagulation, with systemic consequences. Infrequent monitoring, late detection, failure to adapt therapies, hematologic and biochemical abnormalities, coagulopathies, and systemic inflammation can all contribute t...
Cremer J, Ross J, Paranjape V.General anesthesia in equine patients is associated with a higher risk of mortality despite improved monitoring equipments and anesthetic techniques most likely due to their large body size, unique physiology and anatomy, behavioral tendencies, and therefore the challenging recovery. Larger body mass, increased age, higher American Society of Anesthesiologists (ASA) status, out-of-hours surgery, and longer duration of anesthesia have been identified as contributing factors increasing the risk of perioperative mortality in equine patients. Especially the recovery period remains a critical time ...
Phillips NAI, Hackett ES.Respiratory surgery and procedures typically focus on conditions of the upper airway that restrict airflow at rest or exercise. This article focuses on respiratory anatomy and common surgeries of the trachea and larynx in horses. The trachea serves as the airway conduit from the larynx to the bronchi. A variety of upper airway disorders can lead to obstruction and in these instances, tracheotomy is typically utilized to bypass these obstructions and maintain airway patency. Emergency and permanent tracheotomy procedures are discussed. Other common upper airway operations, such as laryngotomy, ...

Ralletti MV, Meistro F, Tarasconi MA, Mandrioli L, Renzi A, Rinnovati R, Spadari A.Extraskeletal chondromas (ESCs) are rare benign tumours composed of mature cartilage that typically develop in soft tissues. Their occurrence in horses is extremely uncommon and, to the authors' knowledge, no previous cases of lingual ESCs in equines have been reported. This report describes a two-year-old Quarter Horse colt presented with progressive dysphagia. Clinical examination revealed a solitary, multilobulated, firm-elastic mass located at the dorsal aboral portion (base) of the tongue. Diagnostic imaging ruled out bone involvement. The mass was surgically excised under general anaesth...
Meistro F, Ralletti MV, Rinnovati R, Spadari A.Subjective lameness evaluation during lungeing is routinely performed in equine practice, but its consistency remains limited, especially in cases of mild or complex asymmetry. Objective: This study aimed to assess the agreement between subjective gait evaluations and a markerless AI-based gait analysis system (OAI-MS) in traditional racehorses during lungeing. Intra- and inter-observer agreement of subjective evaluations was also investigated. Methods: 24 traditional racehorses were assessed during routine pre-race inspections (T0) while trotting on a soft surface. Two experienced equine clin...
Jelocnik M, Hall C, Dennis S, Mitchell K, Blishen A, Mashkour N, Anstey SI, Jenkins C, Jeffers K, El-Hage C, McMillan D, Gilkerson J.Infectious diseases significantly impact equine health and welfare, causing illness and death, and loss of productivity globally. One such disease is 'strangles', a highly contagious upper respiratory condition in horses caused by Streptococcus equi subspecies equi (SEE). Diagnostic methods for this pathogen include sensitive molecular assays and less reliable bacterial isolation and biochemical testing. However, the presence of closely related streptococci, such as Streptococcus equi subspecies zooepidemicus (SZOO), may confound diagnosis. Rapid assays for SEE are crucial for outbreak control...
Pan M, Malekipour F, Pivonka P, Morrice-West AV, Flegg JA, Whitton RC, Hitchens PL.Fractures of the distal limb in Thoroughbred racehorses primarily occur because of accumulation of bone microdamage from high-intensity training. Mathematical models of subchondral bone adaptation of the third metacarpal lateral condyles are capable of approximating existing data for Thoroughbred racehorses in training or at rest. To improve upon previous models, we added a dynamic resorption rate and microdamage accumulation and repair processes. Our ordinary differential equation model simulates the coupled processes of bone adaptation and microdamage accumulation, and is calibrated to data ...
Tommasa SD, Raspe S, Farí G, Imperante A, Brehm W.Tendon and ligament injuries in equine athletes pose significant challenges, often leading to prolonged recovery, reduced performance, and increased risk of reinjury. Current treatment strategies, including conservative and surgical approaches, have shown limited success in fully restoring tendon integrity. Autologous blood derivatives, such as autologous conditioned serum (ACS), have emerged as potential regenerative therapies. However, the clinical efficacy of ACS in the treatment of equine tendinopathies remains under investigation. Unassigned: This study aimed to compare the clinical outco...
