Topic:Equine Diseases
Equine diseases encompass a wide range of health conditions that can affect horses, including infectious diseases, metabolic disorders, and genetic conditions. These diseases can impact the overall health, performance, and well-being of horses. Common equine diseases include equine influenza, equine herpesvirus, laminitis, and equine metabolic syndrome. Diagnosis and management of these diseases often require a combination of clinical evaluation, laboratory testing, and appropriate treatment strategies. This page gathers peer-reviewed research studies and scholarly articles that explore the etiology, pathophysiology, diagnosis, and treatment options for various equine diseases, providing valuable insights for veterinarians and researchers in the field.
The legal responsibilities of the veterinary surgeon arising from advances in equine cardiology and in the prescription of drugs for racehorses. The paper examines the responsibilities of the veterinary surgeon in relation to the advances more recently made in the field of equine cardiology. Notwithstanding such advances it is stated that the normal established legal principles apply, in particular in relation to the preparation of certificates, namely that the veterinary surgeon must be sufficiently expert to give the opinion sought, that he must make himself fully aware of the purpose for which the certificate is required and that he must make clear the nature and limitations of any examination carried out.
The value of arterial blood pressure measurement in assessing the prognosis in equine colic. Indirect arterial blood pressure was determined on 33 horses prior to surgical intervention for the diagnosis and/or correction of acute abdominal disorders and a relationship between low systolic blood pressure and non-survival was established. It is suggested that blood pressure determination should be used to augment other methods of clinical and laboratory examination in cases of equine colic.
[Fibrinogen level in clinically healthy horses]. Various sets of horses were examined in view of the necessity of widening the range of biochemical substances for diagnostic purposes in the field of veterinary medicine. The aim of the investigations was to obtain basic information on fibrinogen level and its variability. The average value stated was 280 mg% s = 89, sx = 12, V% = 32). The fibrinogen level in horses of the pronounced oxidation type was lower than in those with reduced metabolism, the difference being connected with the speed of sedimentation of erythrocytes. Repeated examination of a part of the set of horses (n = 10) on three...
Diagnosis and treatment of “verminous aneurysm” formation in the horse. The clinical manifestations, diagnosis and differential diagnosis of "verminous aneurysm" formation at the root of the cranial mesenteric artery and coeliac artery resulting from Strongylus vulgaris larvae migration are described. Forty-nine of 57 cases were successfully treated with low molecular weight dextran (dextran 70).
Chromatographic separations of alphavirus strains by hydroxylapatite. Hydroxylapatite column chromatography methods were developed to characterize selected alphavirus populations. Different conditions of pH and phosphate molarity were required to obtain satisfactory elution profiles and separations for Western equine encephalomyelitis virus strains, compared with Eastern equine encephalomyelitis virus and Semliki Forest virus strains. Raising the pH of the buffers effected earlier elutions of all viruses. Selection of phosphate gradients with more gentle slopes and adjustment to the proper pH effected better separations of virus subpopulations. Elution profiles ...
[Strongyloides westeri Ihle, 1917 (Nematoda: Strongyloididae). I. Parasitological features of natural infection (author’s transl)]. Patent S. westeri infection is particularly common in unweaned foals (61.2 per cent). It is much less common in foals which have been weaned (15.4 per cent). Examination of the faeces of ten artificially reared foals (free from worms) did not supply any evidence of possible prenatal (intra-uterine) helminth infection. In one Shetland pony mare, larvae of S. westeri were found to be present in the milk on the tenth, twenty-fourth and thirty-second day after parturition. Larvae were not detected in the milk of the other mares but all foals showed patent S. westeri infection within from thirteen ...
Effects of storage on the methaemoglobin content of equine blood. Equine blood containing different levels of methaemoglobin was stored under varying conditions and the methaemoglobin content was monitored during the storage period. Only under aerobic storage at 4 degrees C did the methaemoglobin content of all samples appear to remain stable.
Ischemic myelopathy caused by fibrocartilaginous emboli in a horse. A horse that suddenly became recumbent had a focal ischemic infarct of the spinal cord between C6 and C7. The infarct was attributed to multiple fibrocartilaginous emboli. Adherence of fibrocartilaginous debris to the outer surface of the dura was interpreted as evidence that intervertebral disc degeneration and displacement of the nucleus pulposus had occurred and that the emboli arose from the disc.
National individual identification of horses. Methods of equine identification including signalment, blood typing tattooing and freeze marking are discussed. A new system of individually identifying horses with an unalterable freeze mark is proposed. Unalterable numerical and alphabetical symbols have been developed to apply a registration number to the animal.
An outbreak of Swainsona poisoning in horses. On 6 properties in south-western Queensland an outbreak of nervous disease occurred horses due to ingestion of Swainsonia (Darling pea). Loss of condition, depression, hyperaesthesia and hyperexcitability were seen in affected horses. At autopsy of 2 horses generalised c ytoplasmic vacuolation was seen in the neurones of the central nervous system and in the liver, adrenal and thyroid. The clinical and pathological features were similar to those described in horses suffering from Swainsona poisoning in Australia and Astragalus and Oxytropis in North America.
[Pathogenesis of equine infectious anemia (with reference to similar chronic viral infection)]. 1. Equine infectious anemia (EIA) is an immunologically-medicated disease. Immune complexes formed in blood and tissues are responsible for most symptoms and lesions (anemia, splenomegaly, lymphadenopathy, glomerulonephritis, etc.). In addition, a state of cellular hypersensitivity of the delayed type is involved in the pathogenesis. 2. Periodical attacks of pyrexia and clinical illness in the presence of immunity are caused by antigenically-modified variants of virus. By means of immunosuppressive treatments similar relapses of fever associated with the appearance of new virus variants can be...
[Results obtained using various types of suture material in laparotomy and the treatment of umbilical hernia in horses (author’s transl)]. Comparative studies were done on healing of the wound following laparotomy through the ventral wall of the abdomen (paramedian incision or in the linea alba) in seventy horses and following surgical treatment of umbilical hernia in eighty-five (young) horses, in which perlon, (chromic) catgut, stainless steel wire and polyglycollic acid were used as suture material. Though with some reserve, as the study was concerned with the comparison of findings in clinical cases in which a number of conditions may vary, it is concluded that steel wire and polyglycollic acid are preferable to perlon and (c...
Esophageal patch grafting as a treatment for esophageal stricture in a horse. Esophageal patch grafting, using the sternocephalicus muscle, was used for treatment of cervical esophageal stricture in a mare. The mare was maintained during the initial healing phase by total parenteral nutrition.
Dystrophic myodegeneration in adult horses. Five horses with histories of colic developed signs of myocardial failure and skeletal muscle disease. Necropsy revealed pale areas in the cervical, pectoral, pelvic, and cardiac musculature; histologically, the lesions were indicative of dystrophic myodegeneration. Serum vitamin E concentrations were normal in 2 of the horses but serum selenium concentrations were normal in 2 of the horses, but serum selenium concentrations were low when compared with values obtained from clinically normal horses.
[Cyathostominosis: a form of severe strongylidosis (author’s transl)]. A form of strongyle infection in young horses and ponies, observed during the period from November to May, is described. Large numbers of larvae of Cyathostominae in the fourth or early fifth stage of development are found to be present in the (often watery) faeces. This excretion of larvae is not affected by treatment with anthelmintics. A large number of these patients die from the sequelae of verminous enteritis.
