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.
Khosravi AR, Mahmoudi M.Between 1994 and 1998, a total of 790 feather, hair and skin specimens from a variety of animals with suspected dermatophytoses were studied, of which 248 (31.4%) yielded dermatophytes. The most frequent dermatophytes isolated were Microsporum canis (38.3%), Trichophyton verrucosum (31.8%), T. mentagrophytes (13.3%) and M. gypseum (7.7%). There was a significantly higher proportion of positive cultures from cats (54.8%) than dogs (8.2%), and M. canis was the most common species isolated (87.2 and 50% respectively). Trichophyton verrucosum was the most frequent causative agent of dermatophytose...
Palm F, Walter I, Budik S, Kolodziejek J, Nowotny N, Aurich C.After artificial insemination or mating an inflammatory response is induced by spermatozoa and components of the inseminate or ejaculate. In order to investigate the inflammatory reaction of the endometrium to different semen extenders, phosphate buffered saline (PBS), seminal plasma (SP), skim milk-based extender (SM) or egg yolk semen extender (EY) was inoculated into the uterus of oestrous mares (n=8) during four consecutive cycles in alternating order. Twelve hours after treatment, a uterine lavage was performed and an endometrial biopsy was taken. An additional biopsy was taken in the oes...
Miller CL, Todhunter R.Osteochondrosis affecting the acetabula in horses is rarely reported. Osteochondrosis dissecans in foals only a few weeks old is also an uncommon finding. Lesions compatible with osteochondrosis dissecans in the acetabulum were found to be the cause of a chronic coxofemoral lameness in a 3-week-old Arabian filly. The history, physical examination findings, joint fluid analysis, gross pathologic and histopathologic findings are described.
Hooper PT, Williamson MM.The most important clinical and pathological manifestation of Hendra virus infection in horses and humans is that of severe interstitial pneumonia caused by viral infection of small blood vessels. The virus is also capable of causing nervous disease. Hendra virus is not contagious in horses and is spread by close contact with body fluids, such as froth from infected lungs. Diagnosis should be based on the laboratory examination of blood, lung, kidney, spleen, and, if nervous signs are present, also of the brain. Evidence of infection with the more recently identified and related Nipah virus wa...
Meister D, Tschudi P, Hermann M, Lutz H.The QBC V hematology system was tested with respect to its application in veterinary medicine. PCV's and counts of total leukocytes, granulocytes, lympho/monocytes and platelets collected from 435 horses, dogs and cats were determined and compared with conventionally measured values. Precision and accuracy were found to be good for the majority of parameters. In the authors' opinion the QBC V hematology system is well suited for use in veterinary practice.
Bowling AT, Ewalt-Evans R.Family data are presented for a new allele (Aabdg) in the A system of horse erythrocyte alloantigens which includes factors Aa and Ab traditionally thought to be products of allelic genes. Evidence for incorrect assignment of the codominant factor Ae in the presence of Ab and Ac and the absence of Aa is discussed.
Kalinová Z, Cisláková L, Halánová M.Ehrlichiosis and anaplasmosis are zoonoses caused by bacteria from the family Anaplasmataceae, including human and animal pathogens. The human pathogens are Ehrlichia chaffeensis, the causative agent of human monocytic ehrlichiosis (HME), Anaplasma phagocytophilum, the pathogen causing human granulocytic anaplasmosis (HGA), E. ewingii and Neorickettsia sennetsu, granulocytotropic and monocytotropic Ehrlichia species, respectively. Ehrlichia spp. are small, gram-negative, obligate intracellular bacteria. They replicate in the cytoplasmic vacuoles of host cells, especially granulocytes and monoc...
Shaw FD, Morton H.The developing embryo/fetus bears antigens which are foreign to the mother and it could be expected that immune rejection of the conceptus would occur. One of the reasons why the fetus is not rejected is because a depression of the maternal immune response takes place during pregnancy. Serum from pregnant animals of several species has been shown to contain a factor, early pregnancy factor (EPF), which is immunosuppressive. EPF has been detected as early as six hours after mating and its detection could aid diagnosis of early pregnancy in all species.
Warren LK, Whelen A.The gruelling race schedules maintained by horses competing in chuckwagon racing raises concern for the horses' ability to recover quickly and continue to perform at a high level. The amount of bodyweight lost and the time required for recovery of this weight loss have been used to assess the level of stress imposed on horses competing in various multiple-day events. In this study, bodyweights were obtained from 40 Thoroughbred geldings (mean +/- s.e.; bodyweight 521.5 +/- 4.4 kg) before and after racing during a 5 day chuckwagon race meet. Body condition score (BCS) was determined on the firs...
Muñoz A, Riber C, Trigo P, Castejón F.Leukemia, i.e., the neoplasia of one or more cell lines of the bone marrow, although less common than in other species, it is also reported in horses. Leukemia can be classified according to the affected cells (myeloproliferative or lymphoproliferative disorders), evolution of clinical signs (acute or chronic) and the presence or lack of abnormal cells in peripheral blood (leukemic, subleukemic and aleukemic leukemia). The main myeloproliferative disorders in horses are malignant histiocytosis and myeloid leukemia, the latter being classified as monocytic and myelomonocytic, granulocytic, prim...
Stolk PW, Firth EC.Eight metatarsophalangeal (fetlock) joints were studied in anaesthetized young ponies. Pressure measurements were made in the joint and at various sites in the marrow cavity of the third metatarsal bone with simultaneous measurement of systemic arterial and venous blood pressures. Fetlock joint flexion was always associated with a statistically significant initial decrease in intra-articular pressure (p < 0.05) followed by a marked increase in pressure (p < 0.05). Subsequent extension was accompanied by a similar pressure pattern, although there appeared to be a hysteretic relationship. ...
Han H, Dong H, Chen Q, Gao Y, Li J, Li W, Dang R, Lei C.Testes produce sperm, and investigations into gene expression in the testes will enhance the understanding of the roles of testicular genes in male reproduction. Cryptorchidism, the failure of one or both testes to descend into the scrotal sac, is a common congenital malformation in horses. The major clinical consequence of this abnormality is impaired fertility. The aim of this study was to analyze the expression patterns of testicular genes and to identify the differentially expressed genes (DEGs) in testes between cryptorchid and normal horses. In this study, the gene expression patterns in...
Taylor D.Narrative format, in the form of an invented short story, is used to convey several essential truths in a didactic essay in Neuropsychiatry. Messages, in memorable form, emerge at several levels. Narrative format is essential in biographical medicine and it could be attractive to students at various levels of learning. There are great values and some dangers in biographical science.
Reef VB, Levitan CW, Spencer PA.Sixty-seven horses presented with atrial fibrillation (AF) from January 1, 1980 to August 1, 1986. All horses were evaluated for the type and severity of the underlying cardiac disease and the probable duration of the arrhythmia. Fifty-two (78%) of the horses were treated with quinidine sulfate and/or digoxin. The response to treatment was assessed in each horse. Horses were followed for periods extending from 8 months to 7 years. Standardbreds, young horses, and males predominated in the study group. There were more male horses (stallions and geldings) than mares. Most horses with AF had no e...
Witte W, Strommenger B, Stanek C, Cuny C.Methicillin-resistant Staphylococcus aureus of clonal lineage ST398 that exhibits related spa types and contains SCCmec elements of types IVa or V has been isolated from colonized and infected humans and companion animals (e.g., dog, pig, horse) in Germany and Austria. Of particular concern is the association of these cases with cases of nosocomial ventilator-associated pneumonia.
