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.
Warfarin anticoagulation in the horse. The hematologic and clinical effects of anticoagulation with warfarin were documented in 4 horses. All of the animals had thrombophlebitis (external jugular vein). Measures of coagulation were monitored, with a prothrombin time of 1.5 to 2.5 x base-line value being used as the effective range of anticoagulation. Recanalization was achieved in 2 of 4 cases. Hemorrhage, both subcutaneous and through a surgical incision, was a complication. Vitamin K1, an antidote to warfarin toxicosis, was administered intravenously to reverse anticoagulation and to control hemorrhage.
Anthelmintic efficiency of fenbendazole in equines. A single oral dose of fenbendazole (FBZ) at 10mg/kg body mass was given to 5 donkeys. A further 5 donkeys were dosed with a medicated lick (1 mg FBZ/g lick) until the oral consumption was 10mg/kg body mass. In both trials FBZ was highly effective against adults of the following genera: Cyathostomum, Cylicocyelus, Cylicostephanus, Cylicodontophorus, Poteriostomum, Cabellonema, Craterostomum and Triodontophorus; similarly high efficiency was obtained against the following species: Habronema majus, Habronema musca, Strongylus vulgaris and Oxyuris equi and worms identified as belonging to the subf...
Equine pyelonephritis and unilateral nephrectomy. The clinical and laboratory findings of illness in a 2-year-old Thoroughbred filly are described. The treatment employed, including unilateral nephrectomy, and the macro- and microscopic findings in the diseases kidney are presented and this rare case is discussed briefly.
Recovery of peripheral chemoreceptor function after denervation in ponies. Resting ventilation (PaCO2) and ventilatory responses to acute hypoxia and to intravenous NaCN were assessed over a 4-yr period following cutting of the carotid sinus nerves and stripping the adventitia of the aortic arch. The data indicated essentially complete loss of peripheral chemoreceptor function immediately after surgery and hypoventilation during normoxia (delta PaCO2 = +8.7 Torr). There was a time-dependent, partial recovery of peripheral chemoreceptor function between 2 and 22 mo after surgery. Approximately 10% of the ventilatory response to iv NaCN returned, and 30-40% of the norm...
Criteria for development of animal models of diseases of the respiratory system: the comparative approach in respiratory disease model development. Advances in the understanding of human respiratory disease can come from careful clinical studies of the diseases as they occur in man, but such studies are naturally limited in terms of experimental manipulation. In the last 2 decades, an increasingly complex plethora of experimental respiratory disease models has been developed and utilized by investigators, but relatively less attention has been paid to the naturally occurring pulmonary diseases of animals as potential models. This paper is aimed at presenting selected examples of spontaneous pulmonary disease in animals that may serve as e...
In vitro susceptibility of Haemophilus equigenitalis, the causative organism of contagious equine metritis 1977, to antimicrobial agents. The in vitro susceptibility of recent clinical isolates of Haemophilus equigenitalis to various antimicrobial agents was determined by the disk diffusion test and the World Health Organization-International Collaborative Study agar dilution procedure. Ampicillin and tetracycline were the most active drugs. All strains were susceptible to beta-lactam antibiotics, chloramphenicol, trimethoprim-sulfamethoxazole, nalidixic acid, nitrofurantoin (Furadantin), and bacitracin. All but two strains were resistant to streptomycin, whereas all strains were susceptible to the other aminocyclitol antibodies...
Rectal prolapse in the horse. Eleven horses with rectal prolapses were examined at Purdue University. Nine of the 11 prolapses were corrected by submucosal resection. Four of those were treated by a modified submucosal resection that apposes mucosa as well as submucosa. Follow-up of 8 cases, at intervals ranging from 4 months to 6 years, established that rectal prolapse did not recur following the resection.
Effects of denervation of the digit of the horse. A study was conducted in an effort to explain why digital necrosis sometimes follows neurectomy in the horse. Six horses were subjected to unilateral section of the medial and lateral palmar nerves. Arteriography was done on each digit prior to surgery. Terminally, arteriography was repeated. Sections of bone, nerve, artery, skin, coronary band, and deep flexor tendon were examined histologically. Changes in arterial pattern and bone quality were noted. During the study, 2 of the horses had clinical signs of digital necrosis. The composite findings suggested trauma or infection, or both, of th...
Aspects of genetics and disease in the horse. Dead or deformed foals produced by purebred parents represent an economic and emotional loss to the horse breeder. To avoid repeating production of such defective foals, the breeder may seek assistance in identifying the possible environmental or genetic causes for such animals. Only a few genetic diseases of the horse have been rigorously defined. Selected rare genetic diseases that prevent reproduction, cause the natural death or necessitate the humane destruction of a foal before it fulfills its intended purpose serve as examples for the definition of genetics of other deleterious diseases ...
Counselling for genetic diseases of horses. Dead or deformed foals produced by purebred parents represent an economic and emotional loss to the horse breeder. In order to avoid producing such defective foals in the future, the breeder may seek guidance in determining whether their origin is environmental or genetic. Only a few genetic diseases of horses have been rigorously defined. Selected, rare genetic diseases that prevent reproduction, cause the natural death, or necessitate the humane destruction of a foal before it fulfills its intended purpose serve as examples for collecting evidence to define the genetics of other deleterious ...
Efficacy of ivermectin (22,23-dihydroavermectin B1) against gastrointestinal parasites in ponies. The controlled test method was used to evaluate the antiparasitic efficacy of IM inoculated 22,23-dihydroavermectin B1 (ivermectin) against gastrointestinal parasites of horses (ponies). Parasite infections were naturally acquired in southern Louisiana. Dose levels of the drug tested were 0.2 mg/kg, 0.3 mg/kg, and 0.5 mg/kg. Ivermectin at all dose levels tested had an efficacy greater than 97% (P less than 0.05) against Gasterophilus intestinalis larvae, Trichostrongylus axei, Oxyuris equi larvae, Strongylus vulgaris, S edentatus, 15 species of small strongyles, and small strongyle larvae. Pon...
Correlation of dermal-epidermal laminar lesions of equine hoof with various disease conditions. Dermal and epidermal laminar lesions were correlated with acute intestinal, primary hepatic, septicemic, chronic laminar, and acute laminar diseases. Horses with acute intestinal disease had edema in the secondary dermal laminae. Those with hepatic disease had increased keratinization of the secondary epidermal laminae. Septicemia caused increased keratin formation in the primary and secondary epidermal laminae. Chronic laminitis caused architectural changes of the epidermal laminae characterized by hyperplasia and keratin formation of the basal epidermal layer. Horses with acute laminitis had...
Intra-articular corticosteroid therapy in the horse. Physiologic features of the equine diarthrodial joint and the effects of intra-articular corticosteroid therapy were investigated. It was concluded that intra-articular injection of corticosteroids may be beneficial when lesions are confined to soft tissues of the joint, excluding injuries involving joint laxity. Rest following therapy is important.
Multiple atrial dysrhythmias in a horse. A variety of atrial dysrhythmias including paroxysmal atrial tachycardia, atrial tachycardia with 2nd-grade atrioventricular block, atrial fibrillation, and atrial flutter developed in a 5-year-old Quarter Horse gelding. Quinidine and propranolol were not successful in restoring normal sinus rhythm. Sinus rhythm was re-established during digoxin therapy, but later reverted to atrial dysrhythmia. At necropsy, multiple, discrete pale areas were found on both atria and the interatrial myocardium. Histologic examination of these lesions demonstrated myocytolysis and replacement by fibrous connecti...
Bicipital bursitis in a mare. A case of bicipital bursitis in a six-year-old mare is described. The horse was presented with acute lameness, pyrexia and hot swelling over the right shoulder region. Although antibiotic treatment relieved these signs, a firm cold swelling remained which had to be removed by surgical resection and drainage.
