Topic:Disease Treatment
Disease treatment in horses encompasses a range of medical interventions and management strategies aimed at addressing various health conditions affecting equine species. These treatments can include pharmacological approaches, such as the administration of antibiotics, anti-inflammatory drugs, and antiparasitic medications, as well as non-pharmacological methods like physical therapy, dietary adjustments, and surgical procedures. The selection of appropriate treatments depends on the specific disease, its severity, and the individual needs of the horse. This topic brings together peer-reviewed research studies and scholarly articles that explore the efficacy, safety, and advancements in therapeutic options for equine diseases, providing insights into best practices and emerging trends in equine veterinary medicine.
Treatment of guttural pouch mycosis. Seventeen cases of guttural pouch mycosis (including two bilaterally affected cases) were diagnosed in a three year period. The presenting signs were, in order of frequency, epistaxis at rest, nasal catarrh, pharyngeal paralysis, ipsilateral laryngeal hemiplegia, swelling of the submandibular/parotid region, extension of the head and neck and dyspnoea. Ligation of the origin of the internal carotid and occipital arteries was attempted in 10 of the cases exhibiting epistaxis. Bilateral ligation was performed on one animal with an untoward sequelae. Where surgery was successfully completed furth...
Implantation of a permanent transvenous pacing catheter in a horse with complete heart block and syncope. A permanent, transvenous, atrioventricular, sequential pacing system was implanted successfully in a 7-year-old Quarter Horse gelding with complete heart block. The transvenous atrial and ventricular electrodes were placed in their respective positions in the heart, using real-time, 2-dimensional echocardiography. The horse was able to return successfully to competition as a show horse.
Immunity and potential of vaccination. This article will focus on current information available on the equine immune response to helminth parasites as it relates to acquired resistance, hypersensitivity reactions, and vaccine development.
Large strongyles. Recent advances. This review cites recent advances in the knowledge pertaining to infections of large strongyles in equids. Emphasis is placed on Strongylus vulgaris and attention is focused on pathogenesis of clinical manifestations of infections and treatment and control, including chemotherapy of migrating larvae and drug resistance.
Anthelmintics and drug resistance. Equine anthelmintics and the resistance of nematode parasites to anthelmintics are reviewed. Recommendations are made for effective treatment of these parasites and for procedures that can be performed to minimize the problem in the future.
Parasitic skin diseases. In this discussion of parasitic skin diseases of horses, details on life cycles are given to aid the understanding and development of control strategies.
Shoeing principles for the management of navicular disease in horses. Navicular disease was diagnosed in 36 horses. Each horse was treated, using shoeing as the only major means of treatment. Phenylbutazone was used initially for 10 days after shoeing. Shoeing was designed to correct preexisting problems, enhance physiologic function of the foot, and ease breakover of the foot. The horses were evaluated over a period ranging from 12 to 54 months. The lameness improved in all horses. Thirty-one of the 36 horses treated were not lame when last evaluated. Shoeing was most effective when performed within 8 months of the first signs of lameness. Also, horses used for...
Epidemiology and control of parasites in northern temperate regions. The serious and widespread problem of drug resistance has forced a re-thinking of basic philosophy regarding control of equine parasites. It has illustrated the dangers of total reliance on chemical control and stimulated the use of alternate strategies. Two new approaches are described. Prophylactic treatments in the spring and summer provide effective strongyle and colic control with less selection pressure for drug resistance. A nonchemical approach of pasture cleaning twice a week offers the same advantages with the added bonus of a 50 per cent increase in grazing area.
Other parasites. Recent advances. This article briefly reviews new information on trichostrongylid stomach worms, spirurid stomach worms, tapeworms, threadworms, pinworms, intestinal protozoa, lungworms, eye worms, and numerous other aberrant parasites as it relates to prevalence, pathogenesis of diseases, and treatments.
Ascarids. Recent advances. P. equorum is a common and ubiquitous parasite that persists for many years in stables and on pasture in spite of good hygiene and anthelmintic control programs. Foals are usually infected early in life. During the migratory phase of the infection, clinical signs include coughing and a nasal discharge followed by depression and unthriftiness as the worms mature in the gut. Some foals die as a result of intestinal impaction or rupture. Patency is established around 3 months of age, and fecal egg counts may rise to very high levels. From 6 months of age onwards, the ascarid burden diminishes as ...
Protozoal diseases. The clinical and pathologic findings of and therapy for such protozoal diseases as equine protozoal myeloencephalitis, toxoplasmosis, sarcocystosis, pneumocytosis, cryptosporidiosis, giardiasis, besnoitiosis, and klossiellosis are discussed. Emphasis is placed on disorders that occur with greater frequency in North America and on emerging protozoal diseases affecting horses.
Pharmacokinetic disposition of dimethyl sulfoxide administered intravenously to horses. Dimethyl sulfoxide (DMSO) was administered IV to 6 Thoroughbred horses at 2 dosages: 1.0 g/kg and 0.1 g/kg. The pharmacokinetics seemed linear, with biological half-lives of 8.6 +/- 0.3 hours and 9.8 +/- 2.2 hours for the 1.0 g/kg and 0.1 g/kg dosages, respectively. This was further substantiated by mean residence times of 9.8 +/- 0.44 hours and 13.8 +/- 4.25 hours, areas under the curve of 12.55 +/- 1.42 mg/ml/hr and 1.63 +/- 0.49 mg/ml/hr, and the clearances of 0.081 +/- 0.009 L/kg/hr and 0.066 +/- 0.022 L/kg/hr for the large and small dosages, respectively. At 12 hours after 1.0 g/kg was ad...
[Effectiveness of ivermectin in Strongyloides westeri cases in foals]. Efficacy of Ivermectin in combating Strongyloides westeri infection of foal. The efficacy of Ivermectin and Mebendazol in combating spontaneous Strongyloides westeri infections in foals has been tested by examining faecal egg output reduction. Ivermectin as a paste formulation was given to sucking foals and pregnant mares in a single dosage of 200 micrograms/kg bodyweight by oral administration. A high efficacy of Ivermectin in combating patent Strongyloides westeri infection could be demonstrated; no side effects have been observed. Mebendazol at a dosage rate of 8 mg/kg did not yield satisfa...
Equine ehrlichial colitis (Potomac horse fever): recognition of the disease in Pennsylvania, New Jersey, New York, Ohio, Idaho, and Connecticut. Equine ehrlichial colitis (Potomac horse fever), a newly identified colitis of the horse, was first recognized in Maryland. In this report, we document occurrence of the disease in Pennsylvania, New Jersey, New York, Ohio, Idaho, and Connecticut. Enzootic areas were recognized by a characteristic pattern. Frequently there was a seasonal pattern and high prevalence of sporadic colitis in unstressed horses. The attack rate per farm generally was low. Horses on pasture, as well as those stabled, were affected. Clinical signs varied from fever and depression to severe diarrhea and laminitis. Occas...
Nosocomial infections and bacterial antibiotic resistance in a university equine hospital. A base-line study of bacteria isolated from horses admitted to the Veterinary Medical Teaching Hospital during a 6-month period was performed to determine the extent of multiresistant nosocomial infections caused by gram-negative aerobic bacteria other than Salmonella spp. Results of this study indicated that 21.9% of the 105 horses from which cultures and sensitivities were available had developed nosocomial gram-negative aerobic infections, with high rates of resistance to gentamicin, kanamycin, and trimethoprim sulfadiazine, three of the most often prescribed antibiotics in this hospital. I...
Correction of equine severe combined immunodeficiency by bone marrow transplantation. A 32-day-old horse with severe combined immunodeficiency was transplanted with equine bone marrow cells in an attempt to establish immunologic responsiveness. A histocompatible, mixed-leukocyte-culture-nonreactive, sex-matched, full sibling was used as the donor. Recipient total lymphocyte count, T and B lymphocyte numbers, and response of peripheral blood mononuclear cells to phytolectin stimulation increased by 14 days following transplantation. Circulating lymphocytes exceeded 1000 cells/microliter blood by 40 days posttransplantation, and by 170 days following transplantation, T and B lymp...
Surgical management of intussusception in the horse. During a 14 year period, 27 of 310 horses undergoing laparotomy because of abdominal pain were found to have an intussusception involving the small intestine (16 cases) or caecum (11 cases). The clinical signs, operative findings and techniques adopted to overcome the obstruction are described. An evaluation of possible predisposing factors provided further evidence of the important role of the tapeworm Anoplocephala perfoliata in initiating intussusception involving the ileum and caecum.
Surgical repair of a partial gastric rupture in a horse. RUPTURE of the stomach is a common complication of
gastric impaction and intestinal reflux or of gastric distention.
After rupture, the general condition of the horse deteriorates
and death follows within a few hours (Tennant, Wheat and
Meagher 1972; McIlwraith 1982).
Dietz and Wiesner (1982) state that partial rupture of the
stomach may result in severe blood loss with circulatory
collapse. In this report a partial rupture of the stomach was
surgically repaired during exploratory laparotomy.
