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...
Kot K, Tischner M.The aim of the experiment was to determine the effect of a year-to-year prolonged daylength on the patterns of equine reproductive activity and results of embryo recovery. Experiments using Konik Polski mares were conducted over four reproduction seasons. Five mares were exposed to a regimen of artificially prolonged daylength (APD) and another five mares in a control group were kept under conditions of natural daylight. Both the control and experimental groups were examined for appearance of estrus, ovulation and also for the state of their coats. A single stallion was used for breeding all o...
Anderson DR, Woo SL, Kwan MK, Gershuni DH.Recent studies have shown that the meniscus is highly anisotropic in tension and that its compressive creep behavior can be modeled using biphasic theory. In this study, an alternative approach is used, where viscoelastic shear properties of the meniscal fibrocartilage are measured to determine the anisotropy and inhomogeneity of this tissue with respect to specimen location and fiber orientation. Medial menisci were obtained from eight skeletally-mature horses. Nine test specimens were taken from the circumferential midsubstance of each meniscus, at three circumferential and three axial posit...

However, reference values for oxygenation and biochemical parameters in newborn foals remain limited. Objective: This study aimed to assess the oxygenation status of healthy Mangalarga Marchador foals from birth to 24 h postpartum by evaluating blood gas analysis, Apgar scores, and biochemical and hematological parameters. Methods: Thirty healthy Mangalarga Marchador foals were evaluated. Blood samples were collected from the umbilical artery at birth (T0) and from the dorsal metatarsal artery at 15 ...
Bailey CS, Beachler TM, Mochel JP, Wulf LW, Yaeger M, Kundu D, Withowski K, Papich MG.Despite their widespread clinical use, there is limited pharmacokinetic data for many equine intrauterine antimicrobials. This study aimed to measure the concentration of gentamicin and penicillin in the uterine fluid of mares following infusion of either a standard (PPGent) or long-acting (LA-PPGent) compounded formulation. We hypothesized that both formulations would result in therapeutic concentrations, with total concentrations sustained for longer using the long-acting formulation. Mares were administered 2400 mg of procaine penicillin and 200 mg of gentamicin via a single intrauterin...
Rigby C, Prutton A.Recruitment and retention of equine veterinarians presents an ongoing challenge for employers. Recent research has highlighted factors that contribute to attrition across the profession, but further understanding of the specific challenges faced in the equine sector is needed. This study builds on existing research by exploring the relative impact of different factors on veterinarians' decisions to leave equine clinical practice. Methods: Veterinarians who had left equine clinical practice in the UK within the previous 10 years were invited to participate in an anonymous online survey. The par...
Alves LSS, Hasuda AL, Giordano LGP, Frederico I, Dos Santos IH, Pereira PFV, Lisbôa JAN, Flaiban KKMDC.This study investigated isolation of equine neutrophils and the assessment of their antioxidant function using the nitroblue tetrazolium (NBT) reduction test, an indicator of reactive oxygen species (ROS) activation. The objective was to test the viability of neutrophils isolated from equine whole blood and their ability to undergo respiratory burst, comparing the results with whole blood. The hypothesis tested was that isolation of equine neutrophils allows for effective functional evaluation, even after isolation process, with no significant differences between whole blood and isolated cells...
Beasley B.The overall objective of therapeutic farriery for equine tendon and ligament injuries is to provide a biomechanical environment conducive to healing by limiting excessive strain on the injured structure. With an understanding of equine limb anatomy and the pathophysiology of tendon/ligament injuries, the rationale used in therapeutic farriery for soft tissue injuries of the distal limb is quite logical. Through therapeutic farriery, foot manipulation is used to reduce the tension on the injured tendon(s) or ligament(s).
Zamboulis DE, Thorpe CT.The high stresses and strains experienced by the superficial digital flexor tendon (SDFT) make it prone to age-related injury. The SDFT exhibits cellular and structural specializations, localized to the interfascicular matrix (IFM), enabling it to resist its extreme mechanical environment. With aging, these specializations are lost, impacting the ability of the tendon to withstand repeated loading. Within the IFM, there is loss of mechanical properties and organization accompanying cell senescence and a decreased resolution of inflammation. Developing therapeutics to reverse these changes may,...
Sosa-Portugal S, Dale L, Devaney J, Sharp A, Malalana F, Timofte D.The "ESKAPE" bacteria include a group of organisms known for their multidrug resistance and potential association with nosocomial infections in human and veterinary hospitals.

Schwochow D, Alameddine A, Spörndly-Nees E, Montigny M, Naboulsi R, Jansson A, Niazi A, Lindgren G.Racing without protective shoes is common in the Swedish harness racing industry, as it can enhance horses' performance on the track. Trainers typically decide whether a horse will race barefoot based on practical experience rather than objective measures. However, this practice can sometimes lead to excessive hoof wear, posing potential welfare concerns for racing horses. Gene expression differences may help reveal the underlying genetic mechanisms associated with different phenotypic traits. To explore an objective measure for assessing which horses are best suited for barefoot racing, we co...
Wilson FE, Mair TS, Freeman SL.Referral treatment costs and insurance status impact treatment decisions for colic. Objective: To evaluate changes in the cost of referral treatment for colic, and insurance cover and premiums in the United Kingdom between 2018 and 2023. Methods: Cross sectional study. Methods: Thirty UK equine referral hospitals were contacted in January 2024 and asked about their colic caseload and costs of the last three cases across six categories (surgical +/- resection, euthanasia before, during or after surgery, and medical treatment), using similar methodology to a 2018 study. Data are reported as mean...
Giessen EJM, Stas EKL, Grinwis GCM, Veraa S.A 3-month-old Friesian colt presented with severe, progressive distal limb lameness in two limbs. Radiographic and postmortem full-body CT imaging revealed severe articular deforming osteolysis and osteoproliferation at the dorsodistal navicular bone margin and the adjacent distal phalanx proximo-palmar/proximo-plantar margin in two limbs, with the remainder of the distal interphalangeal joint being unaffected. Multiple other joints showed small osteolytic subchondral defects. Postmortem histopathological examination confirmed focal joint disease of both distal interphalangeal joints, without ...
Mirzaei A, Hajimohammadi A.Sixty-one horses were included in this study and classified into three groups based on the severity of colic, assessed by heart rate, oral mucous membrane color, and abdominal distension. The groups consisted of a strangulating colic (SC) group (n=21), a non-strangulating colic (NC) group (n=20), and a control group (n=20) of randomly selected healthy horses without colic. Serum concentrations of tumor necrosis factor α (TNFα), haptoglobin (Hp), nitric oxide (NO), malondialdehyde (MDA), zinc, iron, and copper were measured in all horses. Receiver operating characteristic (ROC) analysis was c...
Maeda Y, Kanno C, Sugiyama M, Yamamoto R, Sato S, Ando R, Noda R, Kawaguchi H, Takahashi F.A 17-year-old Thoroughbred stallion died suddenly after grazing. Necropsy revealed massive hemorrhage in the pericardial sac, suggesting cardiac tamponade. Aortic perforation was observed at the aortic origin, and hemorrhage was observed in and around the epicardium. Superficial observation of the aortic lumen revealed a transverse tear of the aortic wall at the bases of the right semilunar valve and septal semilunar valve. Fibro-osseous changes with calcification were histopathologically observed at the site of the rupture. A nodular goiter was observed in the left thyroid gland. The horse di...

Burns JJ, Stull J, John E, Doyle A.For horses presenting for colic to a referral hospital in Atlantic Canada, we aimed to describe clinical findings, diagnosis, treatment, and outcome for draft breeds; identify associations between clinical findings, diagnosis, treatment, and outcome for draft compared to nondraft breeds; and identify the overall impact of draft breed on mortality. Unassigned: A retrospective review of equine colic cases presenting to the Atlantic Veterinary College (2004 to 2023). Logistic regression models were used to assess associations between parameters and draft breed and mortality. Unassigned: A total o...
Amari M, Brioschi FA, Auletta L, Ravasio G.Radiofrequency ablation (RFA) and pulsed radiofrequency (PRF) are non-pharmacological techniques employed in humans for chronic pain, but their veterinary application is unexplored. This pilot study evaluated clinical effects of RFA and PRF in twenty-four horses with chronic distal forelimb lameness. Ultrasound-guided RFA (N = 8; 60-90 °C, 2-8 min) or PRF (N = 16; 42 °C; 12 min) was applied to palmar digital nerves. Lameness was scored (American Association of Equine Practitioners scale) at baseline and monthly for six months (T1-T6). At T2, partial- and non-responders in both groups receive...
Willette J, Guinn A, Munsterman A.Impactions of the jejunum are rarely described in the literature. The current case series describes six cases of adult horses with jejunal impactions with feed material diagnosed by exploratory celiotomy. Horses underwent exploratory celiotomy based off of their degree of pain despite medical management and concerns for a primary strangulating small intestinal lesion. All jejunal impactions were relieved via manual decompression of the impaction into the cecum. None of the cases underwent a resection or anastomosis at the site of impaction. All horses were treated with gastroprotectants (omepr...
Dörner C, Lagos N, Oyaneder L, Menarim BC, Ramírez-Toloza G.Osteoarthritis (OA) is an inflammatory joint disease and the leading cause of musculoskeletal disability affecting human and veterinary patients. New therapeutics halting inflammation while preserving joint homeostasis remain a critical need. Voltage-gated sodium (NaV) channels regulate the pro-inflammatory response of macrophages in the synovium, the central driver of joint homeostasis. Neosaxitoxin (NeoSTX) is a phycotoxin that blocks NaV channels, conferring a unique potential to regulate joint inflammation. This study evaluated the safety of intra-articular administration of NeoSTX in hors...
Kovarikova S, Blahova J, Steffenova V, Vaskova N, Jahn P.Currently, there is relatively little published information on the urine protein-to-creatinine (UPC) ratio in horses, a parameter commonly used in dogs and cats. The aim of this study was to determine the reference range of UPC in urine samples of apparently healthy horses and to assess the influence of age and sex. Urinalysis and the determination of urinary protein and creatinine concentrations and ratios were performed. A total of 118 urine samples from apparently healthy horses were included in the study: 10 from foals younger than 6 months and 108 from horses older than 1 year. The median...
Equestrian sports play a significant economic role in the horse industry. In recent years, numerous equine viruses have emerged, among which are equine Pegiviruses and the re-emerging Equine coronavirus (ECoV). These viruses are distributed globally and primarily cause subclinical infections with unknown morbidity, even if ECoV can occasionally induce febrile and diarrheic episodes. To broaden the data on the Italian equine population, a study was conducted to assess their prevalence in two distinct horse populations belonging to the Carabinieri Corps (CC) and the Italian Army (IA) of the Ital...

Shimizu Y, Sugai-Bannai M, Tanabe H, Saito K, Ito H, Tokushige H, Kamiya K, Hirano-Kodaira M, Yamada M, Leung GN.Somapacitan is the second generation of recombinant human growth hormone (rhGH) medication that retains the pharmacological effects of rhGH but exhibits a longer duration of action due to its reversible albumin-binding in the body. In general, the use of all recombinant growth hormone (rGH) analogues is banned by the human and animal sports regulatory authorities due to their anabolic and lipolytic effects. However, little is known about the elimination kinetics and biological effects of the newly introduced long-acting rhGH, somapacitan, in horses. This paper describes the administration stud...
Bacon EK, Parnell D, Muscatello G, McElroy J, Velie BD.The ongoing discussion surrounding the well-being of retired racehorses underscores the importance of implementing effective rehoming strategies that prioritise animal welfare.
