Topic:Diagnosis
Diagnosis in horses involves the systematic identification of diseases and conditions affecting equine health. This process relies on a combination of clinical evaluations, laboratory tests, imaging techniques, and other diagnostic tools to assess the health status of horses. Veterinarians utilize these methods to identify symptoms, determine the underlying causes of health issues, and formulate appropriate treatment plans. Diagnostic procedures in equine medicine can include blood tests, ultrasound, radiography, endoscopy, and more specialized tests such as genetic screening or advanced imaging modalities like MRI and CT scans. This page aggregates peer-reviewed research studies and scholarly articles that explore various diagnostic techniques, their applications, and advancements in the field of equine veterinary medicine.
Effect of spasmolytic analgesic drugs on the motility patterns of the equine small intestine. The effect of acepromazine, Buscopan (Crown Chemicals), pethidine and methadone was evaluated in ponies prepared with Thiry-Vella (T-V) loops. Motility was assessed by electrophysiological means (bipolar electrodes and strain gauge transducers) and by the passage through the T-V loop of a fluid test meal. Results were obtained from 26 experiments in three ponies and compared with six control experiments, in which saline had been administered to the same ponies. Each pony acted as its own control in each experiment and pre and post treatment values for slow wave frequency, spiking activity, del...
Lesions of contagious equine metritis in mares. Twenty-three mares were infected with contagious equine metritis organism by intrauterine inoculation, and necropsied after intervals of two to 116 days. Severe diffuse subacute salpingitis was seen in one mare, and mild multifocal subacute salpingitis was common. Severe diffuse endometritis and cervicitis initially were acute and became more severe, subacute and predominantly plasmacytic by 14 days, then declined but persisted as mild diffuse or multifocal inflammation for the rest of the experimental period. Vaginitis arose in parallel but resolved after 70 days. There were no lesions in the...
Hyperventilation in ponies at the onset of and during steady-state exercise. We studied blood gases in ponies to assess the relationship of alveolar ventilation (VA) to pulmonary CO2 delivery during moderate treadmill exercise. In normal ponies for 1.8, 3, or 6 mph, respectively, partial pressure of CO2 in arterial blood (PaCO2) decreased maximally by 3.1, 4.4, and 5.7 Torr at 30-90 s of exercise and remained below rest by 1.4, 2.3, and 4.5 Torr during steady-state (4-8 min) exercise (P less than 0.01). Partial pressure of O2 in arterial blood (PaO2) and arterial pH, (pHa) also reflected hyperventilation. Mixed venus CO2 partial pressure (PVCO2) decreased 2.3 and 2.9 T...
Antibody responses of ponies to initial and challenge infections of Strongylus vulgaris. An indirect fluorescent antibody assay (IFA) was developed using Strongylus vulgaris third stage larvae (L3) as antigens. Observations using the IFA indicate that a species-specific antibody response to S. vulgaris L3 develops in S. vulgaris-infected ponies and that some surface L3 antigens are shared by adult worms. Sequential antibody levels against S. vulgaris were measured in strongyle-naive and in immune ponies following initial and challenge infections using the IFA and an indirect hemagglutination assay (IHA). Antibody levels measured by IFA increased faster following initial infections...
Extrinsic and intrinsic veins of the equine hoof wall. The extrinsic and intrinsic venous drainage of the equine hoof have previously been poorly described. There is also an absence of information about the venous organisation of both primary and secondary dermal lamellae of the hoof wall. The purpose of this study was to describe the normal venous pattern of the horse hoof, especially that associated with the dermal lamellae of the wall. The venous organisation of 46 pairs of hooves from clinically healthy horses was studied using standard plastic vascular corrosion casts and histological sections. A consistent pattern of venous organisation was ...
[Genetic research in the field of reproductive pathology and genetic prophylaxis in agricultural animals in the Socialist Republic of Romania]. The paper presents the results of some genetic studies accomplished in Romania in the field of pathology of reproduction in domestic animals (pseudohermaphroditism in horses, testicular hypoplasia in he-goats, intersexuality in pigs, freemartinism and genital infantilism in cattle). Also, the use of the cytogenetic test in genetic prophylaxis in pigs and cattle was shown. In addition, the methods for detecting genitors with undesirable genes were devised and perspectives for the development of hereditary hygiene discussed.
Case of equine goitre. A brief review of the literature on equine goitre is presented, together with a case of congenital goitre in a foal. This animal showed localised swelling of the neck, hyperextension of the lower limbs and initial difficulty in sucking. The goitre was removed surgically and the hyperextension successfully treated with surgical shoes and bandaging. The cause was probably iodine deficiency coupled with a goitrogen in the diet.
Animal model of human disease. Infantile X-linked agammaglobulinemia. Agammaglobulinemia in horses. This research explores X-linked agammaglobulinemia in horses, a severe immune deficiency found in various horse breeds, leading to clinical signs like pneumonia and arthritis. Lymphoid tissues show an absence of […]
Severe metabolic acidosis manifested as failure to adapt in a newborn Thoroughbred foal. The research paper discusses the case of a newborn Thoroughbred foal suffering from severe metabolic acidosis, which showed up as an inability to adapt, often referred by the term neonatal […]
Caecal rupture in parturient mares. The pathology of 4 cases of caecal rupture in foaling mares is described. One of these animals died suddenly, probably when rupture occurred, and 3 survived for 5 to 8 h and died from acute peritonitis.
The pathogenesis of this type of injury is discussed and it is suggested that rupture may arise from the pressure of a foetal hind foot against the caecum when distended by local tympany.
A study on the possible role of chymotrypsin in the aetiology of equine chronic obstructive pulmonary disease (COPD). The chymotrypsin activity of seven batches of Micropolyspora faeni and of five batches of Aspergillus fumigatus culture extracts, prepared for inhalation challenge in horses, was assayed and was found to range between 0.29 and 1.45 units/mg protein and 0.02 and 0.20 units/mg protein respectively. Horses affected with chronic obstructive pulmonary disease (COPD) were challenged with two batches of each antigen which had different chymotrypsin activities and no significant correlations were found between the degree of response to challenge and the chymotrypsin activity of the antigens. Inhalatio...
