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.
Marginal pulmonary atelectasis a symptom of viral infection in horses and bovines. No abstract available
Hepatic midzonal necrosis in a pig fed aflatoxin and a horse fed moldy hay. A 35-kg Duroc pig died 3 days after eating a ration containing aflatoxin B1, B2, G1, and G2. It had hemorrhagic enteritis and extensive midzonal necrosis in the liver. A 13-year-old Quarterhorse that died 2 days after eating moldy hay had hemorrhagic enteritis, fatty degeneration of the myocardium and renal tubules, and extensive total midzonal necrosis of the liver.
Osteochondrosis of the equine stifle. Two cases of osteochondrosis are presented. Lesions involving the lateral trochlear ridge of the femur are demonstrated on conventional radiographs and double-contrast arthrograms. A radiographic suggestion of osteochondrosis lesions in the patella is noted. Post mortem examination of one case confirmed the presence of partially free cartilaginous flaps. Reference is made to familial tendency to osteochondrosis in man, dog, pig and horse. The significance of rapid growth rate in the pathogenesis of the condition is also discussed.
Globidium leuckarti infection in a horse with diarrhoea. The history, clinical signs and post mortem findings in a case of Globidium leuckarti infection in a horse with chronic diarrhoea are described. The limited literature concerning this infection is reviewed, with particular reference to pathogenicity.
Cardiac Arrhythmias in the horse. Electrocardiograms were obtained from normal horses and from horses with cardiac or other organic disease that affected the cardiac rhythm. Tracings were obtained from a base-apex bipolar monitor lead, with the negative electrode attached to the skin in the right jugular furrow and the positive electrode attached to the skin on the ventral medline, beneath the apex of the heart. Each arrhythmia was discussed relative to importance and probable cause.
Immunotherapy in two foals with combined immunodeficiency, resulting in graft versus host reaction. Immunotherapy was attempted in 2 Arabian foals with combined immunodeficiency. One foal was given a transplant of bone marrow from a selected full sibling, and 1 foal was given a fetal thymus transplant. Both foals died. Genetic evidence was obtained for survival of the transplanted tissues in both cases; however, a graft versus host reaction developed in the foal given the fetal thymus transplant.
Selective immunoglobulin M deficiency in foals. Selective immunoglobulin M deficiency was diagnosed in 5 foals, on the basis of reduced serum immunoglobulin M concentrations (more than 2 standard deviations below the normal mean). All 5 foals had clinical signs or lesions involving the respiratory tract. Lkebsiella sp was isolated from joint fluids, bronchial lymph nodes, or tracheal washings from the 3 foals in which such samples were available for microbiologic evaluation.
Portal vein anomaly and hepatic encephalopathy in a horse. Periodic episodes of diffuse central nervous system disease occurred in a yearling Thoroughbred gelding that had a history of frequent respiratory tract disease and stunted growth. Hepatic encephalopathy was diagnosed on the basis of history, clinical signs, prolonged bromsulphalein clearance, and increased blood ammonia content. Because of the poor prognosis and recurrent clinical signs the horse was euthanatized. Necropsy revealed an arteriovenous anomaly and thrombosis of the portal vein. Histologically, there was diffuse primary astrocytosis of the brain.
Navicular disease in the horse: risk factors, radiographic changes, and response to therapy. In a retrospective study, 74 horses met defined historical and clinical features indicative of navicular disease. Most of the affected horses were 4 to 9 years old. Males had a greater risk of navicular disease than females, geldings had a greater risk than stallions, and Quarter Horses had a greater risk than other breeds. Diagnostic radiographic changes were found in 42 of 70 horses examined. The distribution of diagnostic radiographic changes between the right and left fron feet was equal. There was no correlation between the finding of diagnostic radiographic changes and the horse's respon...
Recent advances in equine reproduction. Mares rarely ovulate in winter; ovulation is induced by increase in daylight length. Ova accumulate in the oviducts of unserved mares. During pregnancy, corpora lutea accumulate; all regress together at mid pregnancy. Plasma progesterone levels rise and oestrogen levels fall towards the end of pregnancy. Methods are available for early termination of pregnancy and for induction of parturition. Pregnancy can be diagnosed efficiently by rectal examination, and by immunological assay of pregnant mare serum gonadotrophin. Service at the foal heat is associated with an increased prevalence of early...
A general survey of tumours in the horse. Published figures from veterinary schools indicate that tumours may account for about 1 to 3 per cent of surgical cases. In this paper an account is given of clinical and pathological aspects of the tumours that are most likely to be encountered in practice, either as visibly or palpably detectable masses of tissue, or as internal tumours responsible for clinical signs. Amongst the common and important tumours dealt with, the most prominent are "equine sarcoid", squamous-cell carcinoma (of eye region and of glans penis), granulosa-cell tumours and melanomas. Well over a hundred references prov...
