Veterinary medicine for horses encompasses the study and application of medical practices to diagnose, treat, and prevent diseases in equine species. This field involves a comprehensive understanding of equine anatomy, physiology, pathology, and pharmacology. Veterinary practitioners employ a range of diagnostic tools and therapeutic interventions to address health issues in horses, including lameness, gastrointestinal disorders, respiratory conditions, and infectious diseases. Preventative care, such as vaccination and deworming programs, is also a significant aspect of equine veterinary medicine. This page gathers peer-reviewed research studies and scholarly articles that explore various aspects of veterinary medicine as it pertains to horses, including advancements in diagnostic techniques, treatment protocols, and preventive health strategies.
Eddy GA, Martin DH, Reeves WC, Johnson KM.A series of field studies using strain TC-83 attenuated Venezuelan equine encephalomyelitis vaccine in horses was made to determine the rate of seroconversions, the postvaccination viremia, and the possibility of adverse reactions to the vaccine. The rate of seroconversions varied from 50% in one study to 91 and 100% in two others. The highest level of viremia measured was 7 x 10(3) to 8 x 10(3) plaqueforming units per ml. No adverse reactions to the vaccine were observed in any horses, including 42 pregnant mares and their resulting foals.
Momose A, Tsuji T.When sulpyrine and aminopyrine are administered to the horse, unchanged aminopyrine and its metabolites, 4-methylaminoantipyrine and 4-aminoantipyrine, are detected in the urine by means of thin-layer chromatography (TLC) and gas liquid chromatography. Further identification of aminopyrine and these metabolites was carried out by the gas chromatography-mass spectrometry (GC-MS) method. The procedures for separation and identification are as follows : The excretions were adjusted to pH 9 with ammonium hydroxide and extracted with chloroform. The extract was separated by TLC. The spots were loca...
Milne FJ.FOR MANY YEARS, concern has been expressed at the wastage of young Thoroughbreds at the racetrack. This concern even manifested itself in the publication of a book (1) which referred to the prevailing practice of prematurely start-ing the racing career of the Thoroughbred long before it had attained sufficient maturity to engage in stiff, damaging competition. This is not a fault of the Thoroughbred industry alone, because in certain parts of the U.S.A., Quarter Horses less than two years of age are already racing. We could swing to the opposite extreme, of course, to the pleasure horse world ...
Denny HR.Brucella abortus infection in horses is important not only as a clinical entity but also as a potential source of infection for man and other animals. A review of the current knowledge of this disease in the horses is therefore thought to be useful. The incidence of infection in horses has been the subject of many surveys. Most authors used the serum agglutination test as an indication of infection. The majority of surveys were carried out in about 1930 and these showed a wide range in the proportion of positive reactors from 0.5 to 40 percent. Several factors would account for this: variation...
Franken P, van den Hoven R, Sasse HH, Koeman JP, Goedegebuure SD.The case of a three-year-old mare is reported, in which clinical examination revealed the presence of haemorrhagic diathesis as a result of disseminated intravascular coagulation. The animal also showed severe lameness which was due to involvement of the long bones. The diagnosis was only established after death.
Guthrie AJ, Killeen VM, Mülders MS, Grosskopf JF.The ratio of the cardiopulmonary blood volume to stroke volume is called the cardiopulmonary flow index (CPFI). The CPFI can be determined indirectly from the simultaneous recording of a radiocardiogram and an electrocardiogram. The CPFI and cardiac output were measured simultaneously in horses (n = 10) that were diagnosed as having cardiac disease. The diseased subjects were probably all exposed to feed contaminated with the ionophore, salinomycin, and all showed clinical signs indicative of chronic toxic myocarditis. The results obtained from these subjects were compared with those from cont...
Morlock M, Nassutt R, Bonin V.INTRODUCTION:: Cohesive bandages are applied to the legs of racehorses and horses with limb injuries for protection (prevention of abrasion) and support (reduction of movement at the fetlock joint). The support capacity of all commercially available bandages has been questioned. Consequently, the protection aspect of bandaging and the negative side effects, which can be caused by bandaging (eg pressure induced ischemia with subsequent necrosis), were emphasized. High pressures underneath bandages were shown to cause reduced blood flow. Pressures underneath certain types of bandages were shown ...
Valdez H, Adams OR.After preliminary studies on cadavers, a surgical approach was developed for removal of the medial meniscus, offering maximal exposure and minimal trauma to the articular surfaces of the medial tibial plateau and femoral condyle. Medial meniscectomy was then performed on 10 clinically normal horses that had been given general anesthesia. Nine horses were euthanatized at intervals of 1 to 6 months, and the joints were evaluated grossly and histologically. (One horse will be examined 1 year after surgery). Medial meniscus tears were diagnosed in 5 horses; medial meniscectomy was done on 4 horses...
Russo AM, Ebermayer SE, Mancebo OA, Monzón CM.The fungus Curvularia verruculosa, which produces eumycotic mycetomas, was isolated from skin of horses with granulomatous lesions on the legs. The isolation was made in Sabouraud dextrose agar medium. The horses came from Comandante Fontana suburb, Formosa-Argentina. This finding would be the first report of Curvularia in horses in Argentina.
Hinrichs K, Frazer GS, deGannes RV, Richardson DW, Kenney RM.Serous cystadenoma was diagnosed by histologic examination of a large ovary removed from a 16-year-old Thoroughbred mare with normal estrous cycles. Palpation and ultrasound examination per rectum had revealed an excessive number of follicles in the right ovary. The ovulation fossa was palpable on the right ovary, and the left ovary appeared to have normal activity. Plasma testosterone values were high at the time of examination (0.15 ng/ml), but decreased to normal values (0.09 ng/ml) after removal of the cystadenoma.
Greiner S.The manuscript has the title: "Erkandtnus deren innerlichen Krankheiten des Pferds überhaupt". Through two take downs of the lectures of Ludwig Scotti, the founder of the first school for veterinarians in the German speaking part of Europe and its first teacher, the manuscript is identified as another take down. The first part of the manuscript, which is about internal medicine, in large passages is a literally translation of Lafosse's "Guide de Maréchal". In most passages the second part, which is about pharmacology, is a copy of the German translation of Claude Bourgelat's "Matière médic...
Kearns CF, Lenhart JA, McKeever KH.Erythropoietin (EPO) is the primary hormone of erythropoiesis. Administration of recombinant human erythropoietin (rhuEPO) to improve racing performance in the horse represents a new form of blood doping, which has been associated with increased mortality. While immunoassay kits have become plentiful, very few commercial hormone assays are made specifically for equine research. There is a strong degree of sequence homology reported for EPO among species, which has allowed antibodies designed for human EPO research to be used to determine EPO concentration in other species. The objective of the...
Hagedorn HW, Meiser H, Zankl H, Schulz R.The misuse of opiates in racehorses relates to their effect of increasing locomotor activity. Because methadone, a narcotic analgesic, has been suspected of use as a doping compound in the past, it was added to the list of banned drugs and should be considered in doping control. Because the literature fails to provide information on detection of methadone in blood or urine of horses, an enzyme-linked immunosorbent assay was developed to monitor this narcotic in equine body fluids. Combined with high-performance liquid chromatography, the immunoassay also served to confirm positives indicated b...
Lorenz J, Brounts SH.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.

Quieroz AO, Nehme-Russell NS, Brandão A, Jansen AM.'Mal de Cadeiras' is a disease which causes great mortality in horses in the Pantanal Matogrossense region, Brazil. The agent of this disease is Trypanosoma evansi, a kinetoplastid flagellate which belongs to the Trypanosomatidae family, classified into the Salivarian section. Transmission occurs mechanically by haematophagous Diptera, mainly by Stomoxys sp. and Tabanus sp. and vampire bats. Outbreaks of Mal de Cadeiras in horses result in economic losses, thus limiting their use in cattle raising. Ten isolates of T. evansi recently derived from coati (Nasua nasua, Carnivora, Procyonidae), hor...
Tomizawa N, Nishimura R, Sasaki N, Kadosawa T, Senba H, Hara S, Takeuchi A.Cervical myelography and survey radiography was performed on 12 light breed wobbling foals and a new radiographic measurement method was applied for more accurate diagnosis of cervical vertebral instability. Ratios of stenosis of the spinal canal on survey radiography and myelography using relative values in an individual foal were defined on radiograms of lateral flexed position of mid-cervical region, and coincidence between the ratios and histopathological lesions in the cervical spinal cord was investigated. Five of 6 foals had ratios of stenosis on myelography more than 40% at the interve...
McCoy AM, Goodrich LR.Annular ligament desmotomy is commonly performed in horses with chronic tenosynovitis. Previously reported tenoscopic techniques have limitations related to haemorrhage and awkward instrumentation. Radiofrequency (RF) energy affords precision and excellent haemostasis and may be a good alternative to sharp transection of the annular ligament in horses. Objective: To describe a technique for using a RF probe for tenoscopic-guided annular ligament desmotomy and to report the clinical outcome of horses in which it was performed. Methods: Cadaver specimens (n = 14) and live horses undergoing unrel...
