Veterinary medicine for horses encompasses the study and application of medical practices to diagnose, treat, and prevent diseases in equine species. This field involves a comprehensive understanding of equine anatomy, physiology, pathology, and pharmacology. Veterinary practitioners employ a range of diagnostic tools and therapeutic interventions to address health issues in horses, including lameness, gastrointestinal disorders, respiratory conditions, and infectious diseases. Preventative care, such as vaccination and deworming programs, is also a significant aspect of equine veterinary medicine. This page gathers peer-reviewed research studies and scholarly articles that explore various aspects of veterinary medicine as it pertains to horses, including advancements in diagnostic techniques, treatment protocols, and preventive health strategies.
Haque RU.A technique for identifying and characterizing staphylococcal hemolysins by first separating them electrophoretically in barbital-buffered agar gel (pH 8.4) at 5 ma/cm for 2 hr and then determining their hemolytic activities by exposing them to human, horse, rabbit, and sheep erythrocytes is described. The alpha-hemolysin produced by a White variant of the Wood 46 strain of Staphylococcus aureus migrated 18 mm towards the cathode, and it lysed horse, rabbit, and sheep erythrocytes, whereas a Clear variant of the Wood 46 strain of S. aureus produced a lysin which migrated similarly to the alpha...
Rockey JH.Eight antigenically unique immunoglobulins have been identified in purified equine anti-p-azophenyl-beta-lactoside (Lac) antibody isolated from a single horse. The Fc fragments of the gammaGa-, gammaGb-, gammaGc-, and -gammaA-globulins have been shown to possess unique antigenic determinants. Common gammaG- and gammaA-Fc fragment antigenic determinants, which were absent from the 10Sgamma(1)- and gammaM-globulins, have also been observed. All antibody populations share two antigenically distinct light (B, L) chain variants. The association of anti-Lac antibody with the hapten p-(p-dimethylamin...
Friis NF, Bech J.Döhle bodies were observed in a horse suffering from a chronic pleurisy. The bodies were demonstrated in about 80 % of the neutro-phils in blood smears prepared during an acute flare-up of the disease. One to 4 bodies were found in each cell, situated in the periphery of the cytoplasm. The size of the bodies was 1–3 μ and the shape rodlike or oval. They stained blue with M-G-G. Blood smears were examined from 50 horses suffering from various diseases, but Döhle bodies could not be demonstrated in any of these cases. Döhle-Körperchen wurden bei einem Pferd mit chronischer Pleuritis beoba...
Ohnesorge VB, Deegen E, Jöchle W.Detomidine was used in this field trial effectively as a sedative and analgesic for laryngoscopic examinations in a total of 193 foals and 806 mature horses (Hanoverians). Detomidine was given either i.v. in foals 3 to 11 months old (20 micrograms/kg) and in mature horses (15 micrograms/kg), or i.m. in foals below 6 months of age (35 micrograms/kg). After i.v. administration, laryngoscopy was tolerated in more than 90% of all animals without additional use of a twitch, while in foals treated i.m. more than 70% required a twitch in order to enable this procedure. The effectiveness of detomidine...
Katkiewicz M, Witkowski L, Kita J.The aim of this study was to investigate the structure of lymphatic organs in foals which died due to Rhodococcus equi infection. The material for this study consisted of 9 foals, of both genders, various breeds, 6-14 weeks old. The routine histopathological examination and immunocytochemical reaction for cytokeratine-3 receptors revealed the disturbances in the thymus epithelial cells development. This was manifested by a complete lack of cells expressing cytokeratine-3 receptors, as well as absence of normal thymocytes differentiation. The supposed thymus epithelial cells were very few, expr...
Palmieri G, Panu R, Asole A, Branca A.The proprioceptive innervation of the external cremaster muscle of some domestic animals was studied. Muscle spindles and tendon organs with their well-known features were found, but this finding was uncommon and unexpected in the investigated animals. For this reason, we believe that there is no relationship between the presence of these proprioceptors and the cremasteric reflex.
Uldahl M, Bundgaard L, Dahl J, Clayton HM.This study addresses the presence and location of natural pigmentation, potentially pathological changes in pigment, interruptions of the natural lining (scars), roughness, and erosions/contusion (bruising) in and around the corners of the lips of 206 horses presented to a veterinarian for routine preventative dental treatment. After sedation, photographs were taken and later evaluated for the presence of lesions. During the photographic analysis, the Oral Commissure Assessment (OCA) protocol was developed to map precisely the areas of skin and mucosa around the corners of the lips, and the pr...
Fidani M, Gamberini MC, Pasello E, Palazzoli F, Dimasi T, Montana M.A development of a rapid and sensitive LC-MS/MS method for the simultaneous detection of active ingredients of the euthanasic veterinarian drug Tanax mixture is described. The method proposed, with a retention time of few minutes (6 min) was developed for an equine serum sample with solid-phase extraction (S.P.E). This S.P.E. procedure has been revealed useful for the determination of very low concentrations of Tanax analytes (0.05-1 ng/ml). The method was validated in terms of specificity/selectivity, sensitivity, recovery and precision.
Büttner J, Brehm W, Gittel C.In horses, colic is associated with relatively high mortality rates. Identification of parameters associated with poor outcome may aid in providing a more accurate prognosis. This study aimed to assess the early prognostic value towards survival of the horse based on parameters of the clinical examination. Methods: In a retrospective study (2013-2017), results of the clinical examination of horses with colic were analyzed. Obtained parameters were categorized from physiologic up to different pathophysiologic manifestations. The risk of death was calculated as odds ratios in comparison to norma...
Binder H, Jakob C, Bucher P.Successful application of embryo transfer (ET) has become common practice in cattle, horses, sheep, goats and a variety of other species held in captivity. Yet in cattle only has the technique been established commercially. In 1994 more than 100,000 bovine embryos have been transferred in European countries. Important progress in transvaginal ovum pick up (OPU), in vitro production (IVP) and cryopreservation have further improved the applicability of ET. Direct transfer simplifies the procedure considerably allowing individual transfers and eliminating the need of synchronizing recipients. In ...
Lee JH, Lee T, Lee HK, Cho BW, Shin DH, Do KT, Sung S, Kwak W, Kim HJ, Kim H, Cho S, Park KD.Genetics is important for breeding and selection of horses but there is a lack of well-established horse-related browsers or databases. In order to better understand horses, more variants and other integrated information are needed. Thus, we construct a horse genomic variants database including expression and other information. Horse Single Nucleotide Polymorphism and Expression Database (HSDB) (http://snugenome2.snu.ac.kr/HSDB) provides the number of unexplored genomic variants still remaining to be identified in the horse genome including rare variants by using population genome sequences of...
Hill DW, Hyde WG, Kind AJ, Greulich D, Hopkins S.Aramine (metaraminol bitartrate) has been found in the possession of horse trainers and veterinarians who have been investigated for possible inappropriate drug administration to racing horses. Metaraminol (3-hydroxyphenylisopropanolamine) is a sympathomimetic amine that directly and indirectly affects adrenergic receptors, with alpha effects being predominant. Because it has the potential to affect the performance of a racing horse, its use is prohibited. In the present study, methods for the detection of metaraminol were developed. Metaraminol was found to be extracted with poor recovery ( 9...
Erickson GA, Maré CJ.Goat Venezuelan equine encephalomyelitis (VEE) antiserum and normal serum were conjugated and evaluated for staining sensitivity and specificity. Cross-staining with either eastern or western equine encephalomyelitis virus-infected cells did not occur. The baby hamster kidney (BHK-21) cell line when combined with highly specific VEE conjugate detected 100 medium suckling mouse intracerebral lethal doses (suckling mouse LD-50/IC) of the 1B subtype of VEE virus per milliliter of equine tissue suspension. Conjugated goat antiserum was assayed for sensitivity for detection of VEE virus-infected eq...
Brimijoin S, Mintz KP, Prendergast FG.Interactions between dansylarginine N-(3-ethyl-1,5-pentanediyl)amide (DAPA) and the cholinesterases were examined by the techniques of enzyme kinetics and fluorescence spectroscopy. When tested with partially purified enzyme preparations, DAPA was a potent inhibitor of butyrylcholinesterase (IC50 = 2 x 10(-7) M) but not of acetylcholinesterase (IC50 = 4 x 10(-4) M). For a detailed study of the effects of DAPA on butyrylcholinesterase (BuChE), the enzyme was purified to homogeneity from horse serum, with the aid of affinity chromatography on N-methyl acridinium. The kinetics of the inhibition o...
