Equine diseases encompass a wide range of health conditions that can affect horses, including infectious diseases, metabolic disorders, and genetic conditions. These diseases can impact the overall health, performance, and well-being of horses. Common equine diseases include equine influenza, equine herpesvirus, laminitis, and equine metabolic syndrome. Diagnosis and management of these diseases often require a combination of clinical evaluation, laboratory testing, and appropriate treatment strategies. This page gathers peer-reviewed research studies and scholarly articles that explore the etiology, pathophysiology, diagnosis, and treatment options for various equine diseases, providing valuable insights for veterinarians and researchers in the field.
Irwin DH, Howell DW."Cube colic" is described and vain attempts to cause the problem on an experimental basis are recorded. It is concluded that not all horses are susceptible to cube colic and if colic occurs in horses being fed on cubes, it is not necessarily due to feeding of cubes. Nomenclature of bowel disorders is considered.
Kero T, Kuussaari J.The purpose of this communication is to report the first diagnosed case of spinal ataxia in the horse in Finland. The horse was atactic and had a wobbling gait. Especially in turning and backing the rear legs tended to swing outwards. Macroscopical studies revealed malformation of the cervical vertebral articular facets and narrowing of the cervical vertebral canal. The vertebral malformation caused the degeneration of the spinal cord, through the compression of the cord. In this paper the macroscopial and microscopical findings are discussed and compared with the findings of other authors.
Bester RC, Coetzer JA.A case of granulomatous enteritis in a 2 year-old Thoroughbred colt is reported. Clinically the horse showed chronic wasting and subcutaneous oedema of the ventral parts of the body and legs. Grossly the wall of the jejunum and ileum was uniformly thickened. Microscopically the lamina propria, submucosa and the tunica muscalaris of the small intestine were infiltrated with lymphocytes, plasma cells, epithelioid cells and occasional multinucleated giant cells. The granulomatous reaction was most marked in the muscular layers of the gut wall.
Bennett D.The gross and histological features of multiple bone infection in two foals are described. In both cases the lesions were confined to the region of the growth plate. Bone and, in some cases, growth plate cartilage destruction has occurred associated with an extensive inflammatory cell infiltration. The significance of the pathological observation is discussed in relation to the pathogenesis of bone infection in the foal.
Bishop WJ.GG is a useful sedative and anaesthetic agent in horses. Used
alone, or in conjunction with barbiturates, it produces a un-
iformly smooth recovery from anaesthesia.
The need to infuse large volumes to obtain the desired effect is
a disadvantage ofthis agent. Few critical studies have been made
on the short and long term effects of administration of GG to
horses. Its pharmacology and clinical use are described and
indicate that it is a safe and useful drug.
Kisailus EC, Kabat EA.The specificity of Bandeiraea simplicifolia lectin I (BS I) has been studied by competitive-binding assays (CBA) using tritium-labeled human B and hog A substances. Blood-group B substances isolated from horse gastric mucosae and from human ovarian-cyst fluids were much better inhibitors of binding of tritiated blood-group B substance to insoluble BS I-Sepharose 2B than were human blood-group A substances from saliva and ovarian-cyst fluid. A and B active blood-group substances showed the same range of potency in inhibiting binding of tritium-labeled hog A substance to BS I-Sepharose 2B. CBA w...
Piccinno M, Rizzo A, Cariello G, Sciorsci RL.In this study, the Authors investigated the modulatory effect of three single doses (10, 10, and 10 M) of neostigmine on the spontaneous contractility of equine pre-ovulatory follicles in an isolated organ bath, to establish the relationship between this acetylcholinesterase inhibitor and ovulation, in the mare. The results indicate that neostigmine increases pre-ovulatory contractility in equine follicles at each dose, but in a different manner. Indeed, the rise in contractility induced by neostigmine at 10 M and 10 M was phasic, while at 10 M it was tonic. The data obtained indicate poss...
Watanabe R, Furuta H, Ueno Y, Nukada T, Niwa H, Shinyashiki N, Kano R.Trichophyton bullosum is a zoophilic dermatophyte that has been rarely isolated from horses and humans in Africa and Europe. This is the first reported isolation of T. bullosum from a horse with dermatophytosis in Japan. The isolate from a skin lesion formed a cream-colored and waxy colony that was slightly elevated in the center. Sequencing of the internal transcribe spacer region of the isolate revealed that it was 100% identical to that of T. bullosum.
Terkawi MA, Alhasan H, Ueno A, Ratthanophart J, Luo Y, Cao S, Kamyingkird K, Aboulaila M, Youn-Kyoung G, Nishikawa Y, Yokoyama N, Xuan X, Igarashi I.A recombinant C-terminal antigen derived from Babesia caballi 48-kDa rhoptry protein (rBc48/CT) was made for the development of a serologically diagnostic test. Antiserum raised against the rBc48/CT reacted specifically with the corresponding native protein by Western blotting and the indirect fluorescent antibody test (IFAT). Next, an indirect enzyme-linked immunosorbent assay (Bc48/CT-ELISA) and an immunochromatographic test based on the Bc48/CT (Bc48/CT-ICT) were constructed and employed for the detection of an antibody to B. caballi in a variety of equine sera. The results of Bc48/CT-ELISA...
Tew WP, Hackett RP.Synovial fluids from 72 equine joints were examined for the presence of cartilage debris, and these findings were compared to findings from visual inspection of the articular cartilage surfaces at necropsy. Synovial fluids from 25 joints with visual cartilage damage contained one or more large particles of articular cartilage. Cartilage fragments were not found in synovial fluids from 42 of the 47 apparently normal joints; thus, a correlation may exist between cartilage debris in the synovial fluid and lesions of the articular surfaces.
Hekmati P, Schels H.Surgical correction of corneal opacities in horses has rarely been documented in detail and is still reported to be in the experimental stage. For this reason, studies of lamellar keratoplasty were conducted on the equine eye using a modified trephine with an adjustable inside quard for grafting of identical discs from the donor and the recipient cornea. Fourteen transplantations, seven with homografts and seven with heterografts, 15 and 9 mm in diameter, were performed. Sharp-edged, vertical, and regular outlined wound margins of the graft and host are essential for good adaptation and healin...
Wood AL, Spradbrow PB.Fetal equine fibroblasts exposed to bovine papillomavirus became transformed by the criteria of morphological alterations and the acquisition of an increased life span, although they failed to grow in soft agar. Papillomavirus genome persisted in the transformed fibroblasts and was apparently not integrated with the cellular genome. These findings support the notion that bovine papillomaviruses are involved in the production of equine sarcoids.
Gysens L, Depuydt E, Patruno M, Haspeslagh M, Spaas JH, Martens A.Sarcoids are the most common equine skin tumours Although they do not metastasize, they can be locally aggressive and cause significant clinical symptoms in affected horses. Despite being common, very little is known about the host immune response and the biological mechanisms underlying persistence and recurrence of equine sarcoids. The latter reflects the need for further research in this field. This in-vitro study used sarcoid explants from horses with naturally occurring sarcoids (n = 12) to evaluate the induction of a humoral immune response directed against equine sarcoid-derived bovin...
Anderson GF.The equine hoof and foot are the most commonly affected anatomic sites of lameness encountered during purchase examination of the performance horse. This article presents a thorough, systematic approach to the clinical evaluation of the hoof and foot relevant to the pre-purchase examination. Normal and abnormal conditions are discussed with reference to their potential effects on future performance and soundness. Proper trimming, balancing, and shoeing principles are emphasized.
Dzongowska-Dzongu T, Kotoński B, Hutny J.Alpha-1,4 leads to 1,4-glucosyltransferase preparations from horse muscles and serum were studied. The enzyme proteins from both tissues are very similar. Both proteins have a molecular weight of 240 000 and consist of four subunits of 60 000 daltons each. pH 5,0 is optimal for the activity. Only substrates with alpha-1, 4-linkages can serve as glucosyl donors for transferase reactions. Km values for both enzymes differ very slightly. At low substrate concentrations the hydrolytic activity can be found in addition to transferase reactions. At the concentration of the substrate higher than 40 m...
