Topic:Disease Diagnosis
Disease diagnosis in horses involves the identification and characterization of illnesses through various diagnostic methods and tools. This process is essential for effective veterinary care and management of equine health. Techniques used in diagnosing diseases in horses include clinical examinations, laboratory tests, imaging modalities such as ultrasonography and radiography, and molecular diagnostics. Blood tests are frequently utilized to assess parameters such as complete blood count and biochemical profiles, which can indicate underlying health issues. Additionally, advancements in genetic testing and biomarker identification have enhanced the ability to detect specific diseases early. This page aggregates peer-reviewed research studies and scholarly articles that explore diagnostic methodologies, their applications, and their impact on equine health management.
Failure to propagate equine infectious anemia virus in mosquitoes and Culicoides variipennis. Laboratory-colonized mosquitoes, Culex tarsalis, aedes aegypti, Culiseta inornata, and Anopheles free-borni, and the biting gnat, Culicoides variipennis, were exposed to equine infectious anemia virus. Exposure to the virus was by intrathoracic inoculation for mosquitoes and by oral ingestion of an infective blood meal through a membrane for C variipennis. After various intervals, groups of 15 to 20 insects were homogenized and inoculated into susceptible ponies. Positive immunodiffusion test results were used as criterion for equine infectious anemia infection in ponies. Virus was not detecte...
Further characterization of Listeria monocytogenes serotype 5. Fifteen strains of Listeria monocytogenes serotype 5 were characteriized for carbohydrate utilization, enzymic reactions, and other differential criteria. Hemolytic patterns were tested on ovine, bovine, equine, human and lapine blood agars. Results were compared with those of previously reported strains of L. monocytogens serotype 5.
Measurement of neutralizing antibody to equid herpesvirus 1 by single radial hemolysis. Antibody to equid herpesvirus 1, which mediates single radial hemolysis, is that responsible for neutralization. Hemagglutination inhibition antibody is not necessarily involved in neutralization or hemolysis.
A case of spermatic arteriovenous anastomosis in the horse. A large anastomosis of the spermatic artery and vein is described. This was found while surgically removing an abdominal testis. Before surgery the animal wanted to rear after exercise and could not stand on 3 legs for any length of time while being shod. This unusual behaviour disappeared after removal of the mass. The performance and conformation of the horse has also greatly improved.
Cardiopathological observations on histopathogenesis of wandering pacemaker in horses. Histopathololgical observations were performed on the heart and cardiac nervous system of 5 horses affected with wandering pacemaker. The histopathological lesions common to all the animals were as follows: (1) Focal fibrosis in the atrial myocardium just beneath the subendocardium and/or in the endo- and subendocardium, and existence of atrial Purkinje-like fibers within the fibrotic lesions, (2) Microvascular altetation, characterized by edematous-loosening and/or fibrous swelling of the walls of the small and minute arteries, in both the atria, (3) Edema in the intracadiac nerves of both th...
[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.
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.
Survival of 59Fe-labeled erythrocytes in cross-transfused equine blood. Whole blood containing 59Fe-labeled erythrocytes (RBC) and unlabeled serum was transfused from a donor horse on 2 occasions into each of 6 recipient horses. Survival of transfused cells was monitored in the recipients as a function of time after transfusion by measuring RBC radioactivity in the recipients. After the 1st transfusion, RBC concentration of 59Fe remained at 60% to 100% of the transfused dose for 4 days, after which radioactivity values dropped to less than 10% of the dose by 6 days in 3 horses. In the 3 other horses, RBC radioactivity dropped immediately after transfusion, reachin...
