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.
Ultrasonography as an adjunct to pregnancy assessments in the mare. Ultrasonographic detection of pregnancy was performed in 952 Thoroughbred mares. Characteristic images were obtained between 12 and 55 days after breeding. Twins in the same uterine horn as well as twins in opposite horns were imaged, and for the first few months of gestation appeared similar to single pregnancies. Growth curves as a function of time were developed, utilizing horizontal diameters of the blastocysts versus breeding dates. Comparisons between horizontal and vertical diameters demonstrated no appreciable differences when observed as a group. Growth curves derived from twins did n...
Purification and characterization of epimeric estradiol dehydrogenases (17 alpha and 17 beta) from equine placenta. Estradiol 17 alpha-dehydrogenase (EC 1.1.1.148) and estradiol 17 beta-dehydrogenase (EC 1.1.1.62) from horse placenta have been purified to homogeneity. Both enzymes are localized in the microsomal fraction and are solubilized in 1.5% sodium cholate. The 17 alpha- and 17 beta-dehydrogenases are separated by selective elution from hydroxylapatite with 0.5 and 1.0 M potassium phosphate, respectively. Subsequent purification is achieved by two affinity-absorption steps using reactive blue 2-agarose and estriol hemisuccinate-Sepharose. Homogeneous estradiol 17 alpha-dehydrogenase has a specific ac...
Urolithiasis in the horse – a review of 13 cases. The presenting signs, treatment and postoperative progress of 13 horses with vesical and urethral calculi are reviewed. Single, discrete stones were present in 10 animals in which the results of treatment were generally good. In three horses with sabulous cystic deposits, urolithiasis was associated with bladder paralysis and the response to treatment was poor.
[Anesthesia in the horse]. The paper describes the problems of injection anaesthesia in the horse. Different commonly used methods, drugs and drug combinations are explained. Their actions and side-effects are compared and discussed.
[Nutrition and skin diseases in the horse]. Skin diseases of the horse can be produced or enhanced through nutrient deficiency, intestinal formation of detrimental substances, photosensitizing compounds and by intake of allergenes. An exact case history regarding feeding is useful for evaluation of every skin abnormality.
[Hypophyseal adenocarcinoma in a horse. A case study]. The paper presents the case-history of a 5-year-old pony suffering from an adenocarcinoma which proceeded from the pars intermedia of the pituitary gland. Neurological and patho-morphological findings are reported.
Suppressor lymphocyte activity in normal and immunodeficient horses. Equine lymphocytes incubated with Con A and isolated on discontinuous BSA density gradients suppressed mixed lymphocyte reactions in a cell dose- and Con A dose-dependent manner. Suppressor lymphocytes were radiosensitive, even after the initial Con A incubation phase was completed. Suppressor activity was consistently demonstrated using peripheral blood mononuclear leukocytes from normal horses, but was absent in thymus cells and variably present in lymph node cells. Suppressor lymphocytes were present in horses with selective IgM deficiency, and within neoplastic lymph nodes from a horse wit...
Three cases of obstruction of the small colon by a foreign body. This report describes fatal obstruction of the small colon of three horses. The obstructions were caused by irregularly shaped enteroliths of which the centres contained a foreign body, namely a guy-rope, a piece of baling twine , and a fishing-line, respectively. The diagnosis was made by post-mortem examination.
Comparison of ELY-2.1 with blood group and ELY-1 markers in the horse. The distribution of ELY-2 was compared to the distribution of blood group factors Aa, Ab, Ac, Ae, Ca, Da, Db, Dc, Dd, De, Df, Dh, Dk, Ka, Pa, Pb, X, Qa, Qc, Ua, and W in 2465 American Standardbred horses and to ELY-1 in 193 American Standardbred horses. The distribution patterns were different in each case. The segregation of ELY-2.1 and factors at the A, C, D, K, P, Q, U and T (W) blood group loci and at the ELA locus indicated that ELY-2.1 is not a product of any of those loci. No segregation data were available for the ELY-1 locus. Family studies indicated that the gene for ELY-2.1 is not s...
Adrenergic receptors in the urethra and prostate of the horse. The presence and types of alpha and beta adrenergic receptors in the urethra and prostate of the horse were studied in vitro using adrenergic agonist and antagonist drugs. The existence of these receptors was shown. This finding was based on the observation that the contractile action was mediated by adrenergic receptors of alpha-1 type, although in the prostate alpha-2 type receptors also participated. Relaxation in both tissues was controlled by receptors of the beta-2 type.
Hyaluronic acid concentration in synovial fluid from normal and arthritic joints of horses. A method previously described was used to determine the hyaluronic acid concentration in synovia from normal and arthritic horse joints. The concentration of hyaluronic acid in the synovia from arthritic joints was found to be significantly lower than the concentration in fluid from normal joints.
