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.
Ectopic ureter in the horse: Three cases and a review of the literature. Ureterovesicular anastomosis resulted in resolution of the clinical signs of urinary incontinence in three horses with unilateral ectopic ureter. Follow-up of two of the horses ten months and three years later indicated no further urinary tract problems; the third horse died four days after surgery from intestinal infarction.Diagnosis can be readily confirmed by antegrade or retrograde ureterography, or endoscopic visualization of the ectopic ureteral openings. Nephrectomy appears indicated in cases of unilateral ectopic ureter with associated ipsilateral urinary tract infection or hydronephro...
Equine infectious anemia: prospects for control. Equine infectious anemia has been managed in most countries by the imposition of testing and quarantine regulations. In the United States, about 700,000 of the more than 7,000,000 horses are tested annually. As long as the status of greater than 90% of the horse population remains unknown and horses are transported and congregate in a relatively unrestricted manner, EIA will continue to exact its toll. Therefore, it is incumbent on the scientific community to continue to develop and refine practical and sensitive diagnostic tests for EIA which will be used in an expanding market, to reduce the...
Neonatal viral diarrhoeas. Diarrhoea continues to be one of the more common and
important causes of economic loss in young animals (Anon
1978). Virus particles identified as rotaviruses, coronaviruses,
calci-like viruses, astroviruses, parvoviruses, and several others
have been detected by direct electron microscopy of ultracen-
trifuged samples of diarrhoeic faeces from young animals and
human infants over the past 20 years. Despite numerous stud-
ies on the many aetiological agents associated with neonatal
viral diarrhoea in recent years (Tzipori 1985), the challenge
for today’s new veterinary graduate is s...
[The pattern of riding injuries]. During the period from 1.1. to 31.12.1988, 104 patients with injuries resulting from riding or other forms of direct contact with horses were examined and treated in a casualty department in the County of Vejle. Antecedent data from these patients were collected. The majority of injuries occurred on falling from the horse and involved particularly the upper part of the body. The commonest injuries were bruises which did not require special treatment. The relationships between concussion, fracture of the humerus and fracture of the clavicle and riding were investigated by odds ratio. Much fewer...
Field efficacy of ivermectin, fenbendazole and pyrantel embonate paste anthelmintics in horses. Three anthelmintic pastes were compared in terms of their ability to suppress the output of parasite eggs in the faeces of 108 grazing horses at four sites in Britain; the horses were treated once with either ivermectin, fenbendazole or pyrantel. At each site, the horses grazed together throughout the trials which took place during the summers of 1985 and 1986. The median periods before parasite eggs reappeared in faeces were 70 days for ivermectin, 14 days for fenbendazole and 39 days for pyrantel embonate. Geometric mean faecal egg counts in the groups treated with ivermectin and pyrantel we...
A computer-derived protocol to aid in selecting medical versus surgical treatment of horses with abdominal pain. In order to determine which variables are useful in identifying horses with abdominal pain requiring surgery, data were analysed from 219 horses presented at one veterinary teaching hospital. Using multiple stepwise discriminant analysis with a recursive partitioning algorithm, we obtained a decision tree that identifies surgical and non-surgical patients. The prevalence of surgical patients was 79 per cent in this population. The sensitivity, specificity, and positive and negative predictive values of this decision tree were 99 per cent, 55 per cent, 90 per cent and 99 per cent respectively. ...
Cantharidin content of two species of Oklahoma blister beetles associated with toxicosis in horses. Cantharidin content of male and female Epicauta occidentalis and E conferta was determined. Aspects of the life cycle of blister beetles, taxonomy, pheromonal and adaptive functions of cantharidin relative to the medico-legal aspects of cantharidin poisoning, prevention and control in horses are discussed.
Potential of infra-red thermography for the detection of summer seasonal recurrent dermatitis (sweet itch) in horses. The feasibility of using infra-red thermography for early and out of season detection of summer seasonal recurrent dermatitis (sweet itch) was tested on 13 sensitive and six insensitive horses in Israel. In summer (June, July and September) six affected mares and two unaffected sensitive mares (one of them a pony) were clearly 'warmer' in the affected zones than three insensitive mares. In winter (February and March) unaffected sensitive horses could be differentiated from insensitive mares by the warm areas detected in the affected zones. Small numbers of Culicoides imicola bites may have bee...
Cross-protective immunity between equine encephalomyelitis viruses in equids. Eighteen equids were inoculated with eastern equine encephalomyelitis (EEE) and 18 equids with western equine encephalomyelitis (WEE) viruses to produce EEE virus- and WEE virus-immunized equids. Twelve surviving EEE virus-seropositive equids, 15 surviving WEE virus-seropositive equids, and 10 nonimmunized, seronegative equids (controls) were subsequently inoculated with an equine pathogenic (epizootic) strain of Venezuelan equine encephalomyelitis (VEE) virus to determine cross-protective immunity. Challenge infection produced 90% mortality in control (nonimmunized) equids, and 40% mortality ...
Management of rectal injuries. Diagnosis, evaluation, and management of the various grades of rectal tears is discussed. Surgical techniques, which include direct closure, diverting colostomies, and placement of temporary rectal liners, are detailed. Also, rectal prolapses and various methods of repair are outlined.
Effectiveness of oxibendazole against benzimidazole-resistant strongyles in horses. Twenty-eight horses with a residual burden of strongyle eggs in the faces after treatment with mebendazole (MBZ) paste were treated with a suspension of either MBZ or oxibendazole (OBZ). Fecal samples were collected before and 14 days after these treatments. The number of strongyle eggs/g (epg) of feces for each horse was estimated using the Cornell-McMaster dilution and the Cornell-Wisconsin double centrifugation procedures. The epg for each horse was transformed using log (x + 1) and in an analysis of variance of the reduction in egg count for each horse on the logarithmic scale, there was a...
Large colon resection. With large colon resection and anastomosis, up to 95 per cent of the length of the large colon has been successfully removed. A hand-sewn end-to-end anastomosis is effective for lesions in the left dorsal colon and pelvic flexure. Transection and a side-to-side anastomosis with stapling equipment is most effective for extensive resections (greater than 50 per cent). Horses with extensive colon resection (95 per cent) have permanent deficiencies of water absorption and digestion of cellulose and protein. Fermentative capacity is reduced, owing to decreased particulate matter retention time in t...
