The study of diseases in horses encompasses a wide range of conditions affecting equine health, including infectious diseases, metabolic disorders, and genetic abnormalities. These diseases can impact various systems within the horse, such as respiratory, gastrointestinal, and musculoskeletal systems, and can lead to significant health challenges. Research in this area focuses on understanding the pathophysiology, diagnosis, prevention, and treatment of equine diseases. Common diseases studied include equine influenza, equine herpesvirus, and laminitis. This page provides access to peer-reviewed research studies and scholarly articles that explore the etiology, clinical presentation, and management strategies of diseases in horses, contributing to the advancement of equine veterinary medicine.
Rossdale PD, Pattle RE, Mahaffey LW.A SYNDROME in newborn thoroughbred foals, characterized by irregular respiration, convulsions, and lung pathology, has been described already1, and its resemblance to the respiratory distress syndrome of the newborn human noted. This latter condition is associated with the absence of the surface active lung lining complex, or lung surfactant2; this absence can be investigated by observation of bubbles obtained from the lung3. From normal lungs bubbles of very low surface tension which show great stability in air-saturated water can be obtained4,5. The present case demonstrates the common facto...
Wijnberg ID, Back W, van der Kolk JH.This paper describes a case of unilateral stringhalt present for 18 months in the right hind limb of a 4-year-old Warmblood gelding. The only abnormalities detected by electromyography (EMG) were a prolonged insertion activity, fibrillation potentials, and positive waves at rest and enhanced EMG activity in the right lateral digital extensor muscle on muscle contraction. This was interpreted as denervation and hyperirritability of this muscle. Both similarities and differences with Australian stringhalt could be found. As described for horses suffering from Australian stringhalt, phenytoin sod...
Kübleck E.The pathology of a horse is described, in which thoracic trauma with costal fracture and a small diaphragmatic defect later led to entrapment of small intestine in the thorax.
Watson ED, Stokes CR.Immunoglobulins A, G and M were localised by immunoperoxidase staining of endometrial sections from ovariectomised mares. Treatment with progesterone or oestradiol-17 beta did not significantly affect numbers of cells secreting any of the isotypes. Mares with persistent endometritis did not have significantly greater numbers of endometrial plasma cells than genitally-normal mares.
Anderson WI, King JM, Rothwell JT.Segmental atresia of the transverse colon was observed at necropsy in a neonatal foal. The dorsal and ventral components of the large colon were fused, and ended blindly. The small colon was collapsed and completely closed at its cranial end. The right and left dorsal and ventral colons were fused into one blind-ended tube. Histologically, eosinophilic intranuclear inclusion bodies demonstrative of Equine Rhinopneumonitis were present in the thymus.
Meinecke B.The present study comprises 31 mares, that showed a permanent unilateral enlargement of the ovary. In 29 patients the ovary in question was removed by a flanc laparotomy in the standing animal. In the histopathologic examination a granulosa cell tumor was diagnosed in 23 cases, a fibroma twice and a teratoma, hematoma, leiomyoma and a cystic ovary each once. Due to the endocrine activity of the granulosa cell tumor, the clinical picture was characterized by changed behaviour and atrophy of the contralateral ovary. Clinically the ovarial blastomas (teratoma, leiomyoma, fibroma) could not be dif...
Allen AL.Postmortem radiography can be a valuable supplement to traditional necropsy. This article provides examples where postmortem radiographs have been useful in diagnosing and documenting lesions in animals, and have helped demonstrate important principles of the pathology and the pathogenesis of lesions identified at necropsy. This article also discusses additional circumstances where the application of postmortem radiography might be worthwhile.
McClure JJ.Although relatively little is known about autoimmunity and autoimmune mechanisms specifically in horses, the similarities between clinical syndromes with identifiable effector mechanisms in horses and other species suggest that comparable mechanisms may be applicable. Our understanding of equine autoimmunity undoubtedly will benefit from the extensive study of autoimmunity in other species.
van der Gaag I, van Bruinessen-Kapsenberg EG, Dik KJ, Kroneman J.A two-month-old female foal with duodenal stenosis is described. The foal was in poor condition and showed an abnormal stable behaviour. She stood preferably with her head stretched out and reposing on the mare's back or on the stable ridge. Salivation was an important symptom. Clinical and radiological examination of the oral cavity, the pharynx, and the oesophagus showed no abnormalities, except for the antiperistaltic wave along the oesophagus. Because of her bad condition the filly was euthanized. At post mortem examination, apart from leukoplakia, an erosive ulcerative inflammation was fo...
Mariën T, Adriaenssen A, Segers L.A modified colon tray to perform large colon evacuations in horses was designed. A funnel-shaped accessory was constructed to create a mechanical separation between the sterile and nonsterile part of the tray. Sterile hooks were used to make a temporary and stabile colostomy. Thirty horses with surgical correction of nonstrangulating large colon obstruction underwent a large colon evacuation with this modified tray. The surgical procedure was uncomplicated and resulted in a positive outcome in 29 horses. This less labour-intensive way to evacuate the large colon results in minor contamination ...
Sonea IM, Bowker RM, Robinson NE, Holland RE.The lungs of neonatal foals contain many nerves immunoreactive for substance P and calcitonin gene-related peptide. These nerves are closely associated with the epithelium, bronchial and pulmonary vessels and the airway smooth muscle of all intrathoracic airways, including non-cartilaginous bronchioles. Activation of sensory nerves in the respiratory epithelium could thus potentially affect, via local axon reflexes, vascular and respiratory smooth muscle in neonatal equine airways. Nerves immunoreactive for these peptides are much more widely distributed within the lung than in adult horses; t...
