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.
Heitmann J, Kirchhoff H, Chercheletzi C, Jonas E, Deegen E.Acholeplasmas were detected in five of 96 feces samples from clinically normal horses. Three of the five strains isolated were identified as A. equifetale, one as A. hippikon, and one was serologically identical with the Acholeplasma strain 881.
Miller RI, Campbell RS.During a clinical study of equine phycomycosis in tropical northern Australia 3 specific forms of phycomycosis were identified. Of 266 cases diagnosed in 5 different laboratories, hyphomycosis caused by Hyphomyces destruens was responsible for 76.7%, basidiobolomycosis caused by Basidiobolus haptosporus for 18.0%, and entomophthoramycosis caused by Conidiobolus coronatus for 5.3%. Most cases of hyphomycosis were observed between March and July, that is after the monsoonal wet summer, but were calculated from clinical histories to originate in the wet season between November and May. Basidiobol...
McIlwraith CW.The postoperative management of the surgical colic patient varies according to the complications experienced. Many of these complications can be related to the time at which surgery is performed
relative to commencement of the problem, the condition of the patient at the time of surgery, the particular condition, and, last but not
least, the surgeon's performance. Some of the points have been discussed elsewhere in the symposium. The maintenance of asepsis, attention to minimizing trauma to the bowel, and appropriate attention
to visceral and parietal closures are all important principles. ...
Cranley JJ.A survey of 1141 horses and ponies, for the presence of hydatid infection, was carried out at an export meat plant near Bristol. Lesions were attributed carefully by morphological, histological and immunological examinations and assessed by flame cell activity. All available detail concerning the animals was recorded. The surveys in the literature were assessed for the criteria on which their figures were based and were compared with the findings of this present survey. Attention was drawn to the apparent discord between the results of some surveys and others.
Buchanan AM, Davis DC, Pedersen NC, Beaman BL.L-phase (CWD) broth and plate media were used in parallel with conventional microbiological media during a 3-year period for culturing synovial and pleural fluids of animals. Two kinds of recoveries were obtained where parallel conventional methods were negative: (1) parent or normal bacteria, in very low numbers; and (2) Type B CWD variants in equally low numbers. Organisms in group 1 were: Streptococcus zooepidemicus from horses (2x); beta-hemolytic streptococci, Lancefield Gp. G (2x); Staphylococcus aureus; Actinobacillus, and Actinomyces viscosus. Group 2 consisted of Bacteroides sp., Prop...
Issel CJ, Adams WV.A horse whose serum reacted equivocally in the agar gel immunodiffusion (AGID) test for equine infectious anemia was studied over a 3-year period. The horse remained afebrile and virus was detected in only 1 of 6 horse inoculation tests. The intensity of AGID test reactions increased temporarily following this evidence for virus. Although the AGID test reaction was equivocal and 5 of the 6 transmission attempts failed, the 1 successful transmission proved the horse was infected.
Frauenfelder HC, Blevins WE, Page EH.Twelve periocular fibrous connective tissue sarcomas in 11 horses were treated with 222Rn. Follow-up periods ranged from 1 to 6 years; the overall nonrecurrence rate at 12 months after therapy was 92%. Two lesions recurred 2 years after treatment, and 1 after 3 years. One of the former lesions has not recurred after a 2nd 222Rn treatment.
Grossman BS, Brobst DF, Kramer JW, Bayly WM, Reed SM.The urine urea nitrogen/plasma urea nitrogen ratio (Uun/Pun), urine creatinine/plasma creatinine ratio (Ucr/Pcr), urine osmolality/plasma osmolality ratio (Uosm/Posm), and fractional excretion of filtered sodium (FENa) were evaluated in 16 horses with acute azotemia to ascertain the significance of each index in the differentiation of prerenal azotemia from renal azotemia. Renal azotemia was diagnosed when renal biopsy or postmortem histologic examination demonstrated evidence of organic renal disease or when azotemia was found in the presence of isosthenuria. The diagnosis of prerenal azotemi...
Modransky P, Welker B, Ryan J.A fourth tarsal bone fracture was treated conservatively in an adult draft horse. Seven months after the injury, the horse had no evidence of lameness and was able to compete in athletic events. It has been suggested that conservative management of these fractures be considered for brood animals or animals used for less strenuous activities. The outcome of this case suggests that fourth tarsal bone fractures can be successfully treated in athletic animals with conservative management.
Smyth DA, Baptiste KE, Cruz AM, Naylor JM.A 6-year-old, 420-kg quarter horse gelding was presented with a 2-month history of difficulty swallowing and dyspnea. The horse was diagnosed with a right guttural pouch empyema with many large chondroids. Two surgeries were required to completely remove all the chondroids from what proved to be a primary distension of the guttural pouch lateral compartment.
Ketzner KM, Stewart AA, Byron CR, Stewart M, Gaughan EM, Vanharreveld PD, Lillich JD.Describe the use of a phalangeal cast as treatment for wounds in the pastern and foot region of horses. Secondly, to evaluate the healing and soundness of horses treated with phalangeal casts. Methods: Retrospective study of 49 horses. Procedures Medical records of 49 horses that were treated with a phalangeal cast for 50 cases of wounds in the pastern and foot region at equine referral hospitals from 1995 to 2006 were reviewed and follow-up information was obtained. Results: Treatment consisted of wound debridement, lavage, wound closure (28 wounds), cast application and antibiotics (84%). At...
Gehlen H, Loschelder J, Walther M.Euthanasia represents a procedure with high responsibility for veterinarians in equine practice. The procedure should avoid pain and suffering for the horse and be carried out with the least possible stress for the patient and its owner. The presented study investigated the emotional impact of a horse's euthanasia procedure on the owner in order to enable development of future recommendations in improving the management of this procedure in horses. Methods: Questionnaires concerning euthanasia of a horse for horse owners and veterinarians, respectively were developed and sent by mail or publis...
Freeman DE, Bauck AG.Repeat celiotomy can be lifesaving in horses with a surgically treatable postoperative obstruction, although guidelines for its use are lacking, except for uncontrollable postoperative pain. Overdiagnosis of ileus as the cause of postoperative obstruction could delay a second surgery so the disease progresses beyond a manageable level of severity. Although many horses respond favorably to repeat celiotomy, complications can be severe and life threatening, such as incisional infection and adhesions. Repeat celiotomy does not seem to exacerbate postoperative ileus, despite additional surgical ma...
