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.
McGuire TC, Poppie MJ.A severe combined immunodeficiency disorder was demonstrated in two Arabian foals which were full siblings. The defect in the B-lymphocyte system was shown by hypogammaglobulinemia, lymphopenia, and absence of germinal centers. The almost total absence of thymic tissue in one foal and the lack of thymic dependent lymphocytes in the spleens of both foals demonstrate a T-lymphocyte defect. In a retrospective study of total available Arabian foal cases, 4 of 15 had evidence of immunodeficiency.
Palozzo A, Celani G, Guerri G, Straticò P, Varasano V, Petrizzi L.Segmental posthetomy, also referred to as circumcision, reefing or posthioplasty, consists of removing a circumferential segment of the internal preputial lamina (internal preputial fold) followed by end-to-end anastomosis of skin edges. The purpose of this case series is to describe the successful outcome of segmental posthetomy for treating different diseases involving the internal or/and external preputial fold, while restoring the normal telescopic function. In this paper, we report the first case of complete degloving injury of the equine penis in the literature (case 1) and describe thre...
Ross KA, Kolb DS, Macedo A, Anderson M, Klein C.This study tested the hypothesis that the presence of prostaglandin E2 in seminal plasma would aid in the transport of phenolsulfonphthalein (PSP) across the uterotubal junction. Five mares in estrus were inseminated during estrus with PSP dissolved in phosphate-buffered saline and during the subsequent estrus with PSP added to a standard insemination dose. Serum and urine samples were obtained at hours 0, 1, 2, and 3 following treatment and examined for the presence of PSP. Phenolsulfonphthalein could not be detected in any of the urine samples collected from mares following either treatment....
Schumacher J, DeGraves F, Cesar F, Duran S.A local anaesthetic agent capable of temporarily resolving lameness after being administered perineurally would be helpful because rapid return of lameness would allow for other analgesic techniques to be performed within a short period of time. Objective: To determine if a 3% solution of ketamine hydrochloride (HCl), administered around the palmar nerves at the level of the base of the proximal sesamoid bones, can improve naturally occurring lameness that can be improved or abolished with a basilar sesamoid nerve block performed using lidocaine HCl and to compare the change in gait produced u...
Hifumi T, Tanaka T, Sato M, Akioka K, Fujimata C, Miyoshi N.Alveolar echinococcosis in slaughtered horses remains a public health issue. This study aimed to develop a Recombinase polymerase amplification (RPA) assay targeting the mitochondrial NADH dehydrogenase subunit 5 () gene of for the rapid detection of equine alveolar echinococcosis. Thirty-six hepatic solid nodules obtained from each horse ( = 36) were evaluated based on histopathological examination and -targeted PCR and then submitted to the RPA assay. The results of the developed RPA assay were 94.4% consistent with those of PCR and Cohen's kappa coefficient value was 0.89 statistically,...
Grădinaru DA, Stirbu C, Păltineanu D, Mironescu D, Manolescu N.The Wyoming strain of equine infectious anemia virus was adapted to cell cultures by 7 passages in horse leukocytes and 14 passages in fetal equine dermal and kidney cells. The virus was made evident by electron microscopy and immunodiffusion tests with antigens prepared from culture fluids.
Bracamonte JL, Duke-Novakovski T.This study evaluated the use of an articulating automated suturing device for laparoscopic closure of the nephrosplenic space in standing horses. Closure of the nephrosplenic space was performed in 4 horses using an automated suturing device. Second-look laparoscopy was performed at 5 weeks. A smooth fibrous adhesion formed between the spleen, the perirenal fascia, and the nephrosplenic ligament in 3 of the 4 horses in which the nephrosplenic space was closed using the automated suturing device. In 1 horse, closure of the nephrosplenic space was not possible due to constant breakage of the end...
Fidel JL.Although the diagnosis of cancer is relatively uncommon in horses, tumors do occur in this species. Surgery, radiation, and chemotherapy are traditional cancer treatments in all species. In equine patients, surgery has often been the only treatment offered; however, not all tumors can be controlled with surgery alone. In small animal oncology, newer and better therapies are in demand and available. Radiation therapy is often used to control or palliate tumors locally, especially to satisfy clients who demand sophisticated treatments. The large size of equine patients can make radiation therapy...
Moll HD, Howard RD, May KA, Cheramie HS.Two adult Quarter Horse geldings were evaluated for signs of abdominal pain. Both horses had signs of depression and distended small intestines on abdominal palpation per rectum. Abdominal exploratory surgery was performed on both horses. In each instance, small intestine was found to be strangulated by components of the spermatic cord. Both horses were euthanatized because of a poor prognosis. Although not commonly observed, incarceration of intestine by components of the spermatic cord should be considered as a cause of small intestine strangulation in male horses. Early recognition of this ...
