Topic:Disease Management
Disease management in horses encompasses the strategies and practices employed to prevent, control, and treat diseases affecting equine populations. This field involves understanding the etiology, transmission, and clinical presentation of various equine diseases, as well as implementing biosecurity measures and therapeutic interventions. Common diseases in horses include equine influenza, strangles, and equine herpesvirus. Effective disease management relies on accurate diagnosis, vaccination protocols, and the use of antimicrobials and other treatments. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, challenges, and advancements in managing diseases in equine health.
Antimicrobial selection and dosage in the treatment of equine bacterial infections. The success of antimicrobial therapy depends on administration of an agent to which the pathogenic microorganisms are susceptible at the concentrations attained at the site of infection. The route of administration, size of the dose and dosing interval must be appropriate for the drug preparation selected. With penicillins in particular, dosage can be tailored to the severity of the infection and quantitative susceptibility of the microorganism. This approach cannot be applied to aminoglycosides because their relatively narrow margin of safety limits the amount which can be administered. In se...
Equine degenerative myeloencephalopathy: a vitamin E deficiency that may be familial. Two horse farms, on which there was a high incidence of proven and suspected equine degenerative myeloencephalopathy (EDM), were studied. Symmetric ataxia and paresis, along with laryngeal adductor, cervicofacial, local cervical, and cutaneous trunci hyporeflexia, characterized the syndrome. Serum vitamin E concentration reflected a deficient state in affected and unaffected horses on both farms when compared with selected reference groups and with published values. A high incidence of the disease was evident in offspring of two particular sires on one farm. Vitamin E supplementation resulted ...
Observations on tracheal mucociliary clearance in horses. The rate of movement up the mucociliary escalator of Technetium99m tagged to macroaggregated albumin was measured in 7 normal horses and 8 with respiratory disease. The activity at 2 sites in the neck, separated by 12-15 cm, was measured using a hand held scintillation counter and rate meter. In normal horses the Technetium complex moved as a bolus up the neck with a mean rate of 1.58 cm/min. In the horses with respiratory disease the Technetium complex was less likely to move as a discrete bolus and in three horses it was not possible to measure the transport rate. The remainder had a mean tr...
Effects of cromolyn in horses with chronic obstructive pulmonary disease. The effect of disodium cromoglycate (cromolyn) in preventing the pulmonary dysfunction caused by the inhalation of barn and hay dust was studied in 5 horses with confirmed chronic obstructive pulmonary disease (COPD). The horses were studied before (Con) and after exposure to hay and dust allergens (Expos) and after pretreatment with cromolyn followed by exposure (Cr-Expos). There was a significant reduction in PaO2 from 86.8 +/- 8.3 to 73.1 +/- 8.8 when the horses were exposed to hay and dust allergens. The PaO2 after pretreatment with cromolyn and exposures was 78.1 +/- 5.5. There were no si...
Evaluation and management of respiratory disease in the horse. Respiratory disease is one of the commonest medical reasons for referring a horse to the Royal Veterinary College, with coughing the main presenting sign. Investigation requires the taking of a detailed history, clinical examination, the use of appropriate diagnostic aids and noting response to medication and management changes. On arrival the horse is stabled in a minimal dust environment, remaining there until discharge. The use of a dust-free box frequently produces a favourable response without the use of medication which in itself is diagnostic. The problem of a horse which is asymptomati...
Observations on the epidemiology and control of Strongylus vulgaris infections. The epidemiology and control of helminth infections in the horse were studied in four small grazing experiments between 1981 and 1984 at the University of Utrecht. At autopsy in November or December negligible Strongylus vulgaris burdens were found in the cranial mesenteric artery of four groups of ponies, which had been treated with an anthelmintic in July and subsequently transferred to a clean pasture. Considerable arterial S. vulgaris burdens were seen in three groups of ponies which were treated with an anthelmintic in July without a move to clean pasture, and in another group of ponies i...
Epizootic vesicular stomatitis in Colorado, 1982: epidemiologic studies along the northern Colorado front range. Epidemiologic evaluations were made of farm personnel on vesicular stomatitis-affected premises along the front range of the Rocky Mountains in Colorado during the 1982 epizootic. A similar antibody prevalence was noted to that of veterinarians and research and regulatory personnel who were involved with the same epizootic. Risk of infection resulted from intimate physical contact with infected horses or cows. Incidence and infection rates in horses were 45%; rates in cows were much lower, only 5%. Some epidemiologic clues were gained by a detailed study of an equine ranch. The pasture was inc...
Plasma endotoxin levels in horses subjected to carbohydrate induced laminitis. Thirteen (65 per cent) of 20 horses subjected to carbohydrate overload developed Obel Grade 3 lameness within 56 h. Increases in plasma endotoxin from control levels of less than 0.1 ng/litre to values ranging from 2.4 to 81.53 ng/litre were measured in 11 (85 per cent) of 13 horses during the onset of Obel Grade 3 lameness. Obel Grade 3 lameness was associated with rises in plasma Gram-negative endotoxin levels in 11 (92 per cent) of 12 horses. Two peak increases separated by 16 h were verified in five (45 per cent) of 11 horses that exhibited both endotoxaemia and Obel Grade 3 lameness. The ...
[Management of chronic obstructive lung diseases]. In 183 cases of chronic obstructive pulmonary disease (COB, COPD) grades I to IV horses were treated with bronchospasmolytic and secretolytic drugs, corticosteroids, mass infusions of physiological saline solution and with combinations of these treatments. The long-term effects of the above described methods of treatment based on questionnaire with the owners will be discussed. The results are to be considered successful if there is no evidence of irreversible alterations of the lungs, and if the horse is kept away from dust as much as possible.
Observations and management of fractures of the proximal phalanx in young Thoroughbreds. A retrospective study of 119 cases of fracture of the proximal phalanx is described. The short incomplete sagittal fracture (split pastern) was most common and carried a good prognosis for a return to racing following conservative treatment. Longer incomplete fractures also had a good prognosis but complete fractures, either through the lateral cortex of the proximal phalanx or through the bone into the proximal interphalangeal joint, required internal fixation. Careful assessment of these and comminuted fractures was essential before surgery was undertaken. Most comminuted fractures were trea...
Maternal behavior. Parturition in mares is rapid and is followed by a brief period of sensitivity to imprinting on a foal. There is large individual variation in normal maternal style, but normal mothers actively defend their foal, remain near the foal when it is sleeping, tolerate or assist nursing, and do not injure their own foal. Disturbance of a mare and foal during the early imprinting period can predispose a mare to rejection of her foal; therefore, it should be avoided. There are a variety of forms of foal rejection and numerous etiologies. Therefore, each case should be evaluated individually.
