Disease diagnosis in horses involves the identification and characterization of illnesses through various diagnostic methods and tools. This process is essential for effective veterinary care and management of equine health. Techniques used in diagnosing diseases in horses include clinical examinations, laboratory tests, imaging modalities such as ultrasonography and radiography, and molecular diagnostics. Blood tests are frequently utilized to assess parameters such as complete blood count and biochemical profiles, which can indicate underlying health issues. Additionally, advancements in genetic testing and biomarker identification have enhanced the ability to detect specific diseases early. This page aggregates peer-reviewed research studies and scholarly articles that explore diagnostic methodologies, their applications, and their impact on equine health management.
Goulden BE.Any condition which leads to a diminution in the size or alteration of the shape of the lumen of the respiratory tract in the horse may result in the production of abnormal respiratory noises at exercise.
McConnel MB, Katada M, McConnell S, Moore R.Electron microscopy was used to demonstrate the presence of viral particles in primary cultures of leukocytes taken from a horse after SC inoculation with the Wyoming strain of equine infectious anemia virus. Unlike previous studies, the exposure virus was not passaged through cell culture prior to horse inoculation. Cultures were begun approximately 1 week before and 1 week after the 1st pyrexic period after inoculation. In both samples, viral particles and cytoplasmic alterations were observed resembling those previously reported in equine infectious anemia virus and other retravirus-infecte...
Firth EC.The signs observed in 6 cases of peripheral vestibular disease included incoordination, head tilt and nystagmus. The intensity of the signs varied greatly with duration of the disease, and in 3 cases facial paralysis was also present. Tympanosclerosis was demonstrable in all cases subject to radiology. Trauma was the causative factor in most cases. The causes of, and relationships between, vestibular dysfunction and concomitant facial paralysis are discussed. The exact etiology of the tympanosclerosis is unknown.
Rohner K, Demuth D.We report cases of adverse reactions, some of which serious, of four frequently used therapeutic substances in several animal species. In order to avoid similar cases we discuss special measures or alternative therapies.
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...
Makrai L, Dénes B, Hajtós I, Fodor L, Varga J.Two hundred and twelve Rhodococcus equi strains were isolated from soil, nasal and rectal swabs of horses and immunocompromised human patients in Hungary and serotyped using Prescott's serotyping system. One hundred and forty-seven strains (69.3%) belonged to serotype 1, 22 strains (10.4%) to serotype 2, 6 strains (2.8%) to serotype 3 and 1 strain (0.5%) to serotype 4. Serotypes 5, 6 and 7 were not found and 36 strains (17%) could not be typed. Serotype 1 (72%) was the type most commonly isolated from clinical samples of foals or from the soil of horse facilities. Six out of 8 R. equi strains ...
Rogger P, Herrmann N, Ottiger H.The registration of adverse events after the use of immunological veterinary medicinal products (VMP) is the aim of the vaccinovigilance reporting system in Switzerland. Adverse events comprise suspected adverse reactions and lack of expected efficacy. Since the Institute of virology and immunology (IVI) is the competent authority for the regulation of immunological VMP in Switzerland, the reporting system is administrated by the IVI. In 2018, 162 reports concerning authorized immunological VMP were received. While most of the reports were submitted by the marketing authorization holders (79%)...
Austin RJ, Dies KH.The protozoan, Klossiella equi was found in the kidneys of an aged Shetland mare raised in the Fredericton area of New Brunswick. This is the first published report of K. equi in a horse in Canada. The microscopic appearance of the parasite in the kidney is described. A brief discussion of other conditions seen in the horse is also presented.
Wissdorf H, Nautrup CP.The cavity, that belongs to the glans clitoridis and that has to be removed in accord with the regulations and rules for the import of horses of CEM carrier states, has not been taken up in the NAV (1983). Conform to the statements of the clinical physicians and to the declarations of the American literature the nomenclature "Sinus clitoridis" is proposed for the international use.
Kopp E, Mayr B, Schleger W.The expression of nucleolus organizer region (NOR) activity in diploid cells was investigated in a model mammalian hybrid system, the hinny (female ass x male horse), by sequential Ag-NOR and chromomycin A3/distamycin A/DAPI (CDD) staining ion lectin-stimulated peripheral blood lymphocytes. In the majority of cases we found non-expression of the horse-derived NOR chromosomes in the hinny. However, in one case there was strong NOR expression on horse-derived chromosome no. 1.
Hanson RR, Nixon AJ, Gronwall R, Meyer D, Pendergast J.Postoperative abdominal fluid changes were compared in 2 groups of horses; those undergoing double small-colon resection and anastomosis (n = 10) and those undergoing exploratory celiotomy alone (n = 5). Peritoneal fluid was collected before surgery and on postoperative days 1, 3, 5, and 7. Total and differential nucleated cell counts, RBC numbers, and total protein and fibrinogen concentrations were evaluated. In both groups, all values were significantly higher than normal on the first postoperative day (after small-colon resection and anastomoses, WBC = 130,350 +/- 23,310 cells/microliters,...
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...
