Veterinary care also involves diagnostic procedures, surgical interventions, and therapeutic treatments tailored to the specific needs of horses. This page gathers peer-reviewed research studies and scholarly articles that explore various aspects of equine veterinary care, including advancements in diagnostic techniques, treatment protocols, and health management strategies to support the well-being and performance of horses.
Surgical management of complete diaphyseal third metacarpal and metatarsal bone fractures: clinical outcome in 10 mature horses and 11 foals. Osteosynthesis of third metacarpal (McIII) and third metatarsal (MtIII) bone fractures in horses is a surgical challenge and complications surrounding the repair are common. Retrospective studies evaluating surgical repair, complications and outcome are necessary to increase knowledge and improve success of long bone fracture repair in the horse. Objective: To evaluate clinical findings, surgical repair, post operative complications and outcome of 10 mature horses and 11 foals with McIII or MtIII fractures that were treated with open reduction and internal fixation (ORIF). Methods: Medical rec...
Lactobacillus equicursoris sp. nov., isolated from the faeces of a thoroughbred racehorse. We previously isolated five strains of putative lactobacilli from the faeces of a thoroughbred horse (a 4-year-old male). Of the five strains, four were identified as members of existing Lactobacillus species; however, sequence analysis of the 16S rRNA gene revealed that the fifth isolate, DI70(T), showed approximately 97 % identity (1325/1366 bp) with the type strain of Lactobacillus delbrueckii. Therefore, we considered the possibility that DI70(T) represents a novel species of the genus Lactobacillus. Cells of strain DI70(T) were Gram-stain-positive, catalase-negative, non-spore-forming, no...

Methods: University Referral Hospital. Methods: Retrospective study. Methods: Forty-four horses/foals admitted between 1986 and 2006 with a diagnosis of diaphragmatic hernia made either at exploratory laparotomy or necropsy. Methods: None. Results: Information from the medical records included history, clinical examination findings a...
Comparative study of the characteristics and properties of tendinocytes derived from three tendons in the equine forelimb. The aim of this study was to determine the characteristic differences in tendinocytes derived from tendons in the equine forelimb, superficial digital flexor tendon (SDFT), deep digital flexor tendon (DDFT) and common digital extensor tendon (CDET), in morphology, proliferation, collagen production ability and ability for synthesis of matrix metalloproteinases (MMPs). Significant differences were observed in cell number in vivo. The cellular number was largest in the SDFT and smallest in the CDET. The values of in vitro proliferation ratios and ability for synthesis of collagen and MMPs were l...
Streptomyces atriruber sp. nov. and Streptomyces silaceus sp. nov., two novel species of equine origin. Two actinomycete strains, NRRL B-24165(T) and NRRL B-24166(T), isolated from lesions on equine placentas in Kentucky, USA, were analysed using a polyphasic taxonomic approach. On the basis of phylogenetic analysis of 16S rRNA gene sequences, morphological observations and the presence of ll-diaminopimelic acid as the diagnostic diamino acid in whole-cell hydrolysates, the new isolates clearly belonged to the genus Streptomyces. Analyses of the phylogenetic positions of strains NRRL B-24165(T) and NRRL B-24166(T) based on 16S rRNA gene sequences of all recognized species of the genus Streptomyc...
Effects of dobutamine on cardiac index and arterial blood pressure in isoflurane-anaesthetized horses under clinical conditions. Volatile agent-induced hypotension may contribute to anaesthetic-related morbidity and mortality in horses. Dobutamine is commonly used to support arterial blood pressure (ABP) but little is known about its cardiovascular effects under clinical conditions. The aim of this clinical study was to elucidate the relationship between cardiovascular function and dobutamine infusion in isoflurane-anaesthetized horses. Forty-four horses anaesthetized for a variety of surgical procedures were studied. Premedication with acepromazine, methadone and detomidine was followed by induction of anaesthesia with...
Visual laterality in the domestic horse (Equus caballus) interacting with humans. Most horses have a side on which they are easier to handle and a direction they favour when working on a circle, and recent studies have suggested a correlation between emotion and visual laterality when horses observe inanimate objects. As such lateralisation could provide important clues regarding the horse's cognitive processes, we investigated whether horses also show laterality in association with people. We gave horses the choice of entering a chute to left or right, with and without the passive, non-interactive presence of a person unknown to them. The left eye was preferred for scannin...
Gas and particle concentrations in horse stables with individual boxes as a function of the bedding material and the mucking regimen. The aim of this study was to compare different types of bedding and mucking regimens used in horse stables on the generation of airborne particulate matter <10 microm (PM10) and 3 biogenic gases (carbon dioxide, nitrous oxide, and especially ammonia). Three separate experiments were undertaken. The experiments were carried out in an enclosed stable (9.7 m long, 8.7 m wide, and 3.5 m high) that had 5 single boxes housing 4 horses. The measuring instruments were set up in the middle of one side of the stable. In Exp. 1, 3 types of bedding material (wheat straw, straw pellets, and wood shavings) ...
Equine pericardium collagen wound dressing in the treatment of the neuropathic diabetic foot wound: a pilot study. Treatment of diabetic foot wounds remains a major health-care issue, with diabetic foot ulcers representing the most common causal pathway to lower-extremity amputation. Although several investigations have examined topical collagen-based dressings, none have specifically looked at equine pericardium. We, therefore, evaluated the effect of the equine pericardium dressing on neuropathic foot wounds. Methods: Twenty-three consecutive patients with 34 neuropathic foot wounds were evaluated as part of a pilot study. An equine pericardium dressing was applied in a standard manner, and the patients ...
Pneumocephalus secondary to removal of an osteoma from the paranasal sinuses of a horse. A 2-year-old Quarter Horse was evaluated because of a progressive left-sided facial deformity and unilateral nasal and ocular discharge. Results: Physical examination revealed convexity of the left frontonasal region, left-sided nasal and ocular discharge, and decreased air flow through the left nares. Radiography and computed tomography revealed an extensively mineralized mass occupying most of the left paranasal sinuses. Results: The mass was surgically debulked, but complete removal was precluded because the mass was tightly adhered to the frontal and maxillary bones. Results of histologic ...
Treatment of acute epistaxis secondary to guttural pouch mycosis with transarterial nitinol vascular occlusion plugs in three equids. 2 horses and 1 pony were evaluated for right-sided (1 horse and the pony) and left-sided (1 horse) acute epistaxis of 1 day's to 1 month's duration. Results: Endoscopic examination of the 3 equids revealed that the hemorrhage originated from the right maxillary artery in 2 equids and from the left internal carotid artery in the third. Mycosis of the auditory tube diverticulum (guttural pouch) was detected in all 3 equids. Results: All 3 equids underwent surgery, and transarterial nitinol intravascular plugs were placed to occlude affected blood vessels. All equids survived for a long period (i...
[The occurrence of the hindgut ciliate Blepharocorys curvigula (Ciliophora: Blepharocorythidae) from horses (Equus caballus Linnaeus, 1758) in the vicinity of Izmir]. Blepharocorys curvigula Gassovsky, 1919 found in the intestine of domestic horses (Equus caballus Linnaeus, 1758), living in the vicinity of Izmir was investigated. It was seen in nine of the thirteen horses examined (69%). This study reports the presence of Blepharocorys curvigula in the intestine of Equids for the first time in Turkey. Specimens were found to be similar to the original descriptions on the basis of morphological characters and biometric data.
Further Development of an Equine Cell Line that can be Propagated over 100 Times. Cell lines originating from horses are necessary for isolation and propagation of equine herpesviruses (EHV). Although we established an equine-derived cell line, FHK-Tcl3, propagation ceased after fewer than 40 passages. In this study, FHK-Tcl3 cell propagation continued beyond 40 passages, achieving over 100 passages. FHK-Tcl3 cells were then cloned by limiting dilution at the 100th passage. Cloned cells were termed FHK-Tcl3.1. FHK-Tcl3.1 cells grew well and were propagated every 3 to 4 days by splitting 1:5. In addition, EHV-1, -2 and -4 showed a clear cytopathic effect (CPE) in FHK-Tcl3.1 ...
Survey of the occurrence of equine deep digital flexor tendon contraction (clubfoot) in the main thoroughbred breeding area in Japan. At 114 ranches in the Hidaka District of Hokkaido, a total of 1,118 Thoroughbred foals that were born from January to June 2003 were examined at different times from May to September of the same year to ascertain the occurrence of clubfoot. Clubfoot was seen in a total of 179 foals (16%) at 89 ranches (78%). Also, 124 of the 179 foals (69.3%) had clubfoot of grade II or higher, and it was found that grade I was likely to be overlooked or rapidly advance. In the present study, the occurrence of clubfoot was higher than expected in the investigated region. Hence, it is necessary to establish acc...
Enteroliths and other foreign bodies. This article focuses on obstructive diseases of the large intestine (large and small colons) caused by intraluminal bodies. Large intestinal obstructions from intraluminal bodies can be divided into the following categories: enteroliths or mineral concretions, bezoars (hair or plant material), and ingested foreign objects. Clinical presentation and treatment of obstructive diseases are presented in this article and are similar regardless of the cause.
Update on treatments for endotoxemia. Endotoxemia is a major cause of morbidity and mortality in horses affected by colic. This article briefly reviews the pathogenesis of endotoxemia in horses with colic, reviews current established treatments, and describes new advances in the treatment of endotoxemia.
New perspectives in equine gastric ulcer syndrome. Equine gastric ulcer syndrome (EGUS) is common in horses. A history of mild intermitted recurrent colic signs after eating is noted in many horses. Management of horses with abdominal pain caused by gastric ulcers is especially difficult, because non-steroidal anti-inflammatory agents, typically used to control abdominal pain, may exacerbate this condition. Effective pharmacologic agents are available to treat EGUS and eliminate abdominal pain, but more comprehensive measures of environmental and dietary management are needed to manage horses with EGUS and prevent recurrence. This article focu...
Coagulopathies in horses with colic. The most common coagulopathy in horses with colic is a hypercoagulable state associated with disseminated intravascular coagulation. The intensity of this coagulopathy depends on the severity and duration of the gastrointestinal lesion, with the ischemic and inflammatory problems and peritonitis being the most frequently affected by coagulopathies. Early initiation of prophylactic therapy significantly reduces the severe hypercoagulable state in horses with intestinal conditions which are recognized to be at high risk for disseminated intravascular coagulation. In addition to the systemic coag...
Inflammatory bowel disease in horses. This article discusses types of inflammatory bowel disease in horses, including pathologic findings and proposed causes. The diagnosis of inflammatory bowel disease is presented in detail, including minimum database, rectal palpation, abdominal ultrasound, abdominocentesis, biopsy procedures, and absorption tests. Treatment recommendations and prognosis are also discussed.
Acute diarrhea in hospitalized horses. The development of diarrhea among hospitalized horses is a major concern for equine veterinary hospitals and referral centers. It is a potential complication of hospitalization for surgical or medical procedures and can contribute to the morbidity and mortality of horses with gastrointestinal and non-gastrointestinal diseases. Unfortunately, it can be difficult to pinpoint the exact cause of acute diarrhea or colitis, and in most cases, the specific etiologic agent is presumptive or undetermined. This article discusses the major etiologic agents of diarrhea in hospitalized horses, considers fa...
Parasitism and colic. Equids are hosts to dozens of species of internal parasites that infect no other domestic animals. Virtually all horses, especially those exposed to pasture, experience some level of parasitism continuously. Despite pathologic evidence of parasitic damage in various organs and tissues, few parasitisms are manifested systemically in well-managed horses. Contrary to conventional wisdom, only three common parasitisms of horses are likely to be manifested as colic: Strongylus vulgaris, Parascaris equorum, and Anoplocephala perfoliata. This article discusses the life cycles, pathophysiology, manife...
Impactions of the small and large intestines. Impactions of the small and large intestines are frequently diagnosed as the cause of colic in horses. An impaction is an accumulation of dehydrated ingesta in a portion of the digestive tract, typically at sites where the intestinal diameter decreases. The specific pathogenesis for impactions is not fully understood, although risk factors have been identified for several types of impactions. Treatment for impactions includes withholding feed until the impaction passes, rehydrating the ingesta, and, if necessary, administering analgesic agents. In severe cases, surgery may be necessary to reli...
Prognosticating equine colic. Prognosticating survival in horses with colic is challenging because of the number of diseases and pathophysiologic processes that can cause the behavior. Although the treatment of horses with colic has improved dramatically over the years, case fatality can still be high because of the delay in recognizing the problem, the time delay inherent in receiving veterinary care, and the lack of effective treatment for the more severe diseases. Intensive case management and surgery for these horses may be expensive and emotionally draining for owners; therefore, providing an accurate prognosis is key...
