Topic:Disease
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.
Neurologic signs and neuropathology associated with a case of equine infectious anemia. Neurologic signs and neuropathologic lesions associated with a case of equine infectious anemia in a 7 year old Quarter-horse mare were studied. Clinical signs included depression, disorientation, circling, knuckling at the fetlock and hypermetria. The neuropathologic lesions were characterized by a granulomatous ependymitis, subependymal encephalitis, choroiditis and hydrocephalus. These lesions were associated with signs of neurologic dysfunction which were the cause of the prominent clinical features.
Some studies on equine strains of Escherichia coli. A detailed study was made of 194 equine strains of E. coli, involving biochemical and serological characters. In these, the equine strains closely resembled E. coli from other sources, and shared antigenic characters with strains isolated from different animal species.
Changes in the sustentaculum tali associated with distension of the tarsal sheath (thoroughpin). Results of the clinical and radiographic examination of 8 lame horses with tarsal sheath distension are described. In chronic cases pathological exostoses were identified radiographically in the sustentaculum tali and were demonstrated at post mortem in 4 of the horses which were destroyed. The prognosis and the feasibility of treatment are discussed in the light of these changes and the associated damage found at post mortem in the deep flexor tendon and its sheath. Trauma to the hock was known to have occurred in half the cases and was suspected in the others.
Tricuspid atresia in a foal. An Arabian crossbred foal was examined because of a suspected congenital cardiac anomaly. There was a grade V/V crescendo-decresendo holosystolic murmur and thrill in the left 4th intercostal space. The foal was slightly cyanotic and polycythemic. Electrocardiography suggested left ventricular hypertrophy. Angiography and cardiac and vascular pressure recordings led to a diagnosis of pulmonic stenosis. The foal died after cardiac bypass and corrective surgery. Postmortem examination revealed an enlarged right atrium, atresia of the tricuspid orifice, a large, fenestrated patent foramen ovale, ...
Metastatic phycomycosis in a horse. Extensive subcutaneous phycomycosis of the lower hindlimb developed over a period of 8 months in a Thoroughbred filly. There was no response to treatments such as trichlorphon, sodium iodide, or etisazole. Extension of the limb lesion over the following 3 months was associated with an enlarged inguinal lymph node, which was removed. Characteristic phycomycotic lesions were observed in the node, and a fungus having the morphologic features of Hyphomyces destruens was isolated from both the limb and nodal lesions.
Splenectomy in the horse. Splenectomy was successfully performed on 2 aged horses to facilitate experimental studies of Babesia equi infection. Resection of part of the 17th rib provided the most acceptable approach and avoided many complications encountered on removing part of the 16th rib.
Priapism after sedation, neuroleptanalgesia and anaesthesia in the horse. The paper reports 6 cases of priapism with subsequent protrusion and paresis after neuroleptanalgesia and anaesthesia in horses. Five were ultimately treated by amputation of the penis but the sixth horse is responding satisfactorily to conservative treatment at the time of writing. Causative factors, preventive measures and possible methods of treatment are discussed.
[Effectiveness of coumaphos against chorioptes bovis in a horse with foot-mange (author’s transl)]. A horse with foot-mange failed to recover following a number of courses of treatment with coumaphos. Mites isolated from this horse were tested in vitro for their sensitivity to coumaphos and lindane. The mites were resistant to coumaphos and sensitive to lindane. Following treatment with lindane, the horse recovered within four weeks.
Ameloblastic ondontoma in a foal. A 4 month old foal with right sided maxillary enlargement and considerable upper airway obstruction had an ameloblastic odontoma in the right maxillary sinus. This odontogenic tumour, probably congenital in nature, had extensively distorted the structure and contours of the sinus, and displaced the adjacent turbinates and nasal septum.
Serological response in mares affected by contagious equine metritis 1977. A serum agglutination and antiglobulin test is described for the detection of antibodies to the contagious equine metritis organism. A provisional interpretation of the test is proposed and using this interpretation the results of 66 such tests are discussed.
Congenital occipitoatlantoaxial malformations in the horse. From a clinical, radiological and morphological study of 9 horses with congenital malformations of the occiput, atlas and axis, and from a study of 2 reported cases, 3 diseases were defined: A. Familial occipitalisation of the atlas with atlantalisation of the axis in Arabian horses (7 cases in this report and the case reported by Leipold, et al., 1974). These horses had congenital atlantooccipital fusion, hypoplasia of the atlas and dens, malformation of the axis and modification of the atlantoaxial joint. B. Congenital asymmetrical occipitoatlantoaxial malformation (2 cases in this report). ...
Induction of a cell membrane antigen by equine infectious anemia virus. Equine fibroblasts persistently infected with equine infectious anemia virus acquire a new cell membrane antigen demonstrable by indirect radioimmunoassay, using infected horse serum as an antibody source.
