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.
Susceptibility of horses to Mycobacterium paratuberculosis. The susceptibility of horses to Mycobacterium paratuberculosis was studied. A total of 8 colts was used: 2 colts were exposed intravenously and 1 colt used as a contact control was placed with them; 2 colts were exposed intragastrically; 1 colt was administered killed M. paratuberculosis intravenously; and the remaining 2 colts were used as normal controls and were housed separately. Colts administered live bacilli intravenously began losing weight 84 days after exposure, and shortly thereafter they had clinical signs of disease, consisting of loss of body weight and rough coat. The exposed co...
Production of antibody to homologous -fetoprotein in rabbits, rats and horses by immunization with human -fetoprotein. The production of antibody to homologous alpha fetoprotein (AFP) in rabbits, rats, and horses by immunication with human AFP is reported. The antigens were administered subcutaneously 5 times at intervals of 7-10 days. Rabbits and dogs received 1 mg of human AFP/ml of the homologous pooled newborn serum with each injection while the rats received 1/2 of the dose. The horses received 5 mg/ml/injection. 2 weeks after the last injection, antisera were collected and immunologic assays were performed by the Ouchterlony method and the reversed version of the Mancini method. High titered antibodies w...
Development of an equine herpesvirus in two cell culture systems: light and electron microscopy. Development of equine herpesvirus strain 82A was studied in cells from primary horse kidney (HOK) cultures and an equine dermis (ED) cell strain. HOK and ED cells are equally susceptible to the 82A virus infection and yield about the same amount of infectious virus. Intranuclear inclusions were present in both cell systems, but a ring-shaped syncytial formation was observed only in infected ED cells. Ultrastructural studies revealed the presence of dense granules 30 nm in diameter and characteristic star-like clusters of granules in the infected HOK cells, but these granules were rarely seen i...
Lead and zinc poisoning and the interaction between Pb and Zn poisoning in the foal. Groups of young growing horses were fed toxic amounts of lead only, zinc only and the same amounts of lead and zinc together. Those fed Pb only developed pharyngeal and laryngeal paralysis ("roaring") whereas those fed Zn only and Pb and Zn together developed the same clinical syndrome which included swelling at the epiphyseal region of the long bones, stiffness and lameness. Anemia and decreased weight gains were most pronounced in animals fed Zn for the longest periods. Animals fed Pb only did not become anemic and weight loss did not occur until after there was an interference in swallowing...
Equine infectious anemia: activity of liquid antigen extracts in the agar-gel immunodiffusion and complement-fixation tests. Twenty-nine lots of acetone-ether extracted liquid antigen were prepared from the pulp of 11 spleens collected from horses at the acute phase of experimental infection. The lots prepared from the highly reactive pulp resulted in general in a liquid antigen of greater activity than those extracted from weakly reactive pulps. Some variations in activity between lots of antigen prepared from the same spleen were also observed. No matter what the results, given a wide enough variation, all results were reproducible. The procedure permitted production of a greater number of antigen test doses from ...
