"Horses" is a broad topic that encompasses various aspects of equine biology, behavior, and management. This category includes studies on the anatomy, physiology, and genetics of horses, as well as their behavior, nutrition, and care. Research in this area may also cover the historical and cultural significance of horses, their roles in agriculture, sport, and therapy, and the challenges associated with their conservation and welfare. The page aggregates peer-reviewed research articles and scholarly studies that explore the multifaceted relationships between humans and horses, examining both scientific and socio-economic perspectives.
Kidd JA, Lamas L, Henson FM.To report repair of a longitudinal scapular fracture in a horse. Methods: Case report. Methods: A 2-year-old Paint Horse colt. Methods: A longitudinal scapular fracture was surgically repaired using four 4.5 mm dynamic compression plates. Results: An acute longitudinal scapular fracture repaired surgically returned the horse to soundness within 6 months. Conclusions: Internal fixation of longitudinal scapular fracture is possible with multiple 3-5 hole dynamic compression plates. Conclusions: Longitudinal fractures of the scapula should be considered when there is lateral instability of the sh...
Roth TL, White KL, Thompson DL, Horohov DW.It has been proposed that PGE2 is an important immunosuppressant acting at the fetal-maternal interface during pregnancy. We have previously shown that horse conceptus-conditioned medium suppresses lymphocyte proliferation. This experiment was designed to determine if horse conceptus-derived immunosuppressive activity could be attributed to PGE2 production by the trophoblast tissue. Trophoblast tissue from 21-day-old conceptuses was cut into equal sections and cultured in the presence or absence of the prostaglandin inhibitor, indomethacin. Following culture, immunosuppressive activity and the...
CRAWFORD M.This disease has a very long history, with the earliest written description by Vegetius in the fourth century A.D. It has many names, such as periodic ophthalmia, recurrent ophthalmia, iridocyclitis, uveitis, moon-blindness, etc. Periodic ophthalmia is perhaps the name more generally used, but I prefer to use recurrent iridocyclitis because (a) there is no definite fixed period between the recurrent attacks and (b) because the essential lesion is iridocyclitis.
Ollis GW, Morin LA, Visser AL.Through collaborations with Alberta Health and Wellness; Alberta Agriculture, Food and Rural Development; Alberta Sustainable Resource Development; and Alberta Environment, a surveillance program was implemented to detect West Nile virus (WNV) in Alberta and to explore the distribution of the virus in mosquito pools, wild birds, humans, and horses. The surveillance in horses was to detect the presence of the virus in Alberta and to explore possibilities of reducing the risk of infection in both humans and horses. This report gives the frequency, distribution, clinical symptoms, and associated ...
Stack A, Schott HC.Adverse drug reactions to trimethoprim-sulphonamide combinations are common in many species, manifesting as gastrointestinal tract disorders, dermatopathies and blood dyscrasias. In this case series, neurological abnormalities in 4 horses being treated with trimethoprim-sulphonamide combinations at normal dosages and in one foal that received an overdose are described. The horses developed hypermetric gait, agitation and erratic behaviour. All signs resolved once medication was withdrawn, and no horse had residual deficits. No other cause for observed neurological deficits could be determined....
Rhiner T, Fettelschoss V, Schoster A, Birkmann K, Fettelschoss-Gabriel A.Previously, virus-like particle (VLP)-based self-vaccinations targeting interleukin (IL)-5 or IL-31 have been suggested to treat equine insect bite hypersensitivity (IBH), a seasonal recurrent allergic dermatitis in horses. The IL-5-targeting equine vaccine significantly reduced blood eosinophil counts in horses, similar to human monoclonal antibodies targeting IL-5 or the IL-5 receptor alpha (IL-5Rα). Previous studies in humans have also reported an additional effect on reduction of basophil counts. The aim of the present study was to evaluate whether an equine anti-IL-5 vaccine affected blo...
Fisher K, Dodam J, Bailey J, Thombs L, Hodgson D, Bukoski A.To compare PaO2 and PaCO2 in horses recovering from general anesthesia maintained with either apneustic anesthesia ventilation (AAV) or conventional mechanical ventilation (CMV). Methods: Randomized, crossover design. Methods: A total of 10 healthy adult horses from a university-owned herd. Methods: Dorsally recumbent horses were anesthetized with isoflurane in oxygen [inspired oxygen fraction = 0.3 initially, with subsequent titration to maintain PaO2 ≥ 85 mmHg (11.3 kPa)] and ventilated with AAV or CMV according to predefined criteria [10 mL kg-1 tidal volume, PaCO2 40-45 mmHg (5.3-6.0 kP...
Georgadze IA, Nozadze ZM.The hyperimmunization of horses with large doses of tetanus toxoid is accompanied by an increase in the levels of both specific antitoxic antibodies and autoantibodies to the tissue antigens of the liver, the spleen, the heart. The reverse relationship between the level of autoantibodies and the titer of antitoxin has been established. The authors suggest that the synthesis of autoantibodies is stimulated by the presence of antigen-antibody immune complexes in the circulating blood, as well as by the action of exo- and endopolyclonal stimulators.
Gretener P.On the basis of an examination carried out on 41 healthy horses, a correlation was established between the average breath stream strength (Vol./Time) during both inspiration and expiration and the breath volume per minute. In the range of breath volume between 45 and 200 liters per minute, it was found that there was a close linear correlation between the breath stream strength, both inspiratory and expiratory, and the breath volume per minute. Comparative examinations, carried out on 56 horses suffering from obstructive lung diseases, have shown that such diseases resulted in a reduction of t...
