Outbreaks of equine grass sickness in Hungary. Equine grass sickness (EGS) occurs mainly in Great Britain, but has once been reported in Hungary. The stud which was affected by EGS in 2001 had no new cases until 2009/10, when 11 of 60 and five of 12 one- to three-year-old colts died or were euthanased due to EGS. Following a few hours in the high-risk field during the winter of 2010/11 further four cases of acute EGS were noted among these horses. The affected horses showed somewhat different clinical signs compared with the cases reported in Great Britain. Histopathological findings in these horses were consistent with EGS. In most examin...
Contagious equine metritis eradicated from Japan. Contagious equine metritis (CEM), a contagious venereal disease of horses, invaded Japan in 1980 and spread in the Thoroughbred population of the Hidaka-Iburi district of Hokkaido. To eradicate CEM, we ran a program aimed at detecting Taylorella equigenitalis, the causal agent, in carrier horses by using the PCR test, followed by culling or treatment. In 2001, the first year of the program, 12,356 Thoroughbred racing stallions and mares were tested and 11 carriers were found. Four, two, one, and one carrier mares were detected in 2002, 2003, 2004, and 2005, respectively, by application of the ...
Mating behavior increases workload of the heart in Thoroughbred stallions. To evaluate the influence of mating behavior on cardiac function, changes in heart rate (HR), electrocardiogram (ECG), hematocrit (Hct) and serum concentration of alpha-atrial natriuretic peptide (alpha-ANP) were evaluated in 10 clinically sound Thoroughbred stallions before and after mating behavior. The stallions were submitted twice to experimental pseudomating in the same month in 2009 and 2010. Measurements and blood samples were collected at a stable before mating (baseline) and at a covering yard before and after mating. ECG was recorded by a Holter-ECG system. Arrhythmias were detected...
Thromboelastography in healthy, sick non-septic and septic neonatal foals.

Additionally, to compare TEG variables, haematological values and conventional coagulation profiles from healthy, sick non-septic, and septic foals. Methods: Prospective study. Methods: The study group comprised 18 healthy, 15 sick non-septic and 17 septic foals. Two citrated (3.2%; 1 : 9 anticoagulant : blood ratio) blood samples were submitted for haemostatic evaluation using a TEG analyser ...
Neuro-ophthalmology in horses. A complete neuro-ophthalmologic assessment is relatively simple, requires minimal instrumentation and should be performed as part of every complete ophthalmic and neurologic examination. This article has summarized the tests that comprise and the species-specific details of the complete neuro-ophthalmologic of the equine patient. Selected causes of sudden blindness in the horse were summarized and some common neuro-ophthalmic conditions with significant ophthalmic consequences, such as facial nerve paralysis, were discussed. Split-lid tarsorrhaphies, which are indicated but rarely used in case...
Lesions of the equine neck resulting in lameness or poor performance. Lesions of the neck are an uncommon primary cause of pain resulting in either lameness or poor performance but should be considered if local analgesic techniques of the limbs fail to abolish lameness or if there are clinical signs directly referable to the neck such as pain, abnormal neck posture, stiffness, or patchy sweating. Accurate diagnosis requires careful clinical examination, exclusion of other causes of lameness or poor performance, and accurate interpretation of diagnostic imaging findings.
Purchase examinations and importation requirements for European performance horses and their semen entering the United States. A comprehensive purchase examination is expected by American clients intent on importing a horse from a foreign country. American veterinarians may be involved in performing purchase examinations in foreign countries or, more often, interpreting findings from foreign veterinarians for their American clients. Exportation and importation requirements for horses and semen vary from country to country. Detailed knowledge of the requirements by all involved veterinarians is essential for efficient and successful international equine travel.
Toxins and adverse drug reactions affecting the equine nervous system. This article provides an overview of the more common toxins and adverse drug reactions, along with more rare toxins and reactions (Table 1), that result in neurologic dysfunction in horses. A wide variety of symptoms, treatments, and outcomes are seen with toxic neurologic disease in horses. An in-depth history and thorough physical examination are needed to determine if a toxin or adverse drug reaction is responsible for the clinical signs. Once a toxin or adverse drug reaction is identified, the specific antidote, if available, and supportive care should be administered promptly.
Evaluation and management of the recumbent adult horse. Evaluation and management of recumbent horses are challenging. Familiarity with disorders that can result in recumbency will facilitate more rapid diagnosis and more appropriate formulation of a prognosis. With rapid and appropriate diagnosis, appropriate treatment can be pursued and, with good nursing care, can result in a favorable outcome.
Treatment of equine sarcoid in seven Cape mountain zebra (Equus zebra zebra). Equine sarcoid has been diagnosed in endangered Cape mountain zebra (Equus zebra zebra) in at least two game reserves in South Africa, with prevalence as high as 53% in Bontebok National Park. Seven Cape mountain zebras with sarcoids were treated with either surgical excision, 5-fluorouracil, allogenous vaccine, or a combination of 5-fluorouracil and allogenous vaccine. One of the two sarcoids on one of the 5-fluorouracil-treated zebras was left untreated. The microscopic features of the tumors evaluated showed either all or most of the typical epidermal and dermal histologic features of equin...
Guttural pouch diseases causing neurologic dysfunction in the horse. The close relationship between guttural pouches, cranial nerves, and sympathetic structures make neurologic abnormalities due to diseases of the guttural pouches (especially mycosis) possible. Recognition of epistaxis or mucopurulent nasal discharge, together with signs of dysfunction of the cranial nerves in contact with the guttural pouches, are important key points in order to consider a comprehensive evaluation of these structures and further definitive diagnosis. Diseases of the guttural pouches can also cause signs such as dysphagia, abnormal soft palate positioning, laryngeal paralysis,...
A study of sub-occlusal secondary dentine thickness in overgrown equine cheek teeth. The presence of cheek tooth loss or defects, with subsequent overgrowth of the opposing teeth, is common in horses. Little is known about the factors that control the deposition of sub-occlusal secondary dentine (SO2D) in normal equine teeth, but these are likely to include stimulation of the occlusal surface. There appears to be no information on the possible alterations to this process when teeth develop overgrowths and, consequently, of the net effect on SO2D thickness caused by reduced stimulation of the occlusal surface and of absent/reduced normal occlusal wear (attrition). Knowledge of ...

Methods: Retrospective case series. Methods: Horses (n = 127) with suspected large colon displacement. Methods: Medical records (January 1998-September 2008) of horses admitted for colic were reviewed. Suspected large colon displacement was diagnosed from clinical examination and in some cases, subsequent surgical examination. Medically managed horses were exercised and administered intravenous fluids and analgesia. Horses with suspected left dorsal displacement (LDD) of the large...
Risk factors for equine laminitis: a systematic review with quality appraisal of published evidence. Epidemiological studies into the risk factors for naturally-occurring equine laminitis are limited. There are a small number of such studies, although the results are inconsistent and remain disputed. The reasons for the conflicting results remain unclear. The aim of this review was to critically evaluate previous research in order to identify publications which provide the best evidence of risk factors for naturally-occurring equine laminitis. A systematic review of English language publications was conducted using MEDLINE (1950-2010), CAB Direct (1910-2010) and IVIS (1997-2010). Additional p...
Standing laparoscopic peritoneal flap hernioplasty technique for preventing recurrence of acquired strangulating inguinal herniation in stallions. To describe a standing laparoscopic peritoneal flap hernioplasty (PFH) technique for closure of the vaginal ring, and to evaluate its effect on prevention of recurrent herniation in stallions, previously treated for acquired strangulating inguinal hernia (SIH). Methods: Case series. Methods: Stallions (n = 30) aged 3-15 that had previous acquired SIH. Methods: Bilateral standing laparoscopic PFH was performed on 30 stallions that had previous acquired SIH treated without castration. The vaginal rings were approached from 3 portals, 2 in the paralumbar fossa and a 3rd between the 17th and 18th ...
First application of axial speed of sound to follow up injured equine tendons. Ultrasonography is an established technique to follow up injured tendons, although the lesions' echogenicity tends to become normal before the tendon is ready to sustain the stresses imposed by exercise. Normalized axial speed of sound (SOS) has been found to correlate with an injured tendon's stiffness; therefore, the purpose of this study was to establish whether SOS would be a useful tool in tendon injury follow-up. Axial SOS was measured in 11 equine superficial digital flexor tendons during a 15-week follow-up period and compared with an ultrasonographic grading system. SOS significantly ...
Vertical head and trunk movement adaptations of sound horses trotting in a circle on a hard surface. Trotting a horse in circles is a standard and important part of the subjective equine lameness examination, yet objective data on this form of locomotion are sparse. The aim of this study was to investigate the effect of trotting in a circle on head and trunk movement symmetry. Vertical movements of the head, withers, os sacrum and left and right tuber coxae were measured using inertial sensors as 12 sound horses were trotted on a hard surface in a straight line and in a circle on both reins. Seven asymmetry measures and hip hike were calculated for each horse for at least nine strides of comp...
Stirrup forces during horse riding: a comparison between sitting and rising trot. Injuries of horses might be related to the force the rider exerts on the horse. To better understand the loading of the horse by a rider, a sensor was developed to measure the force exerted by the rider on the stirrups. In the study, five horses and 23 riders participated. Stirrup forces measured in sitting trot and rising trot were synchronised with rider movements measured from digital films and made dimensionless by dividing them by the bodyweight (BW) of the rider. A Fourier transform of the stirrup force data showed that the signals of both sitting and rising trot contained 2.4 and 4.8 Hz...
Abdominal computed radiography for the diagnosis of enterolithiasis in horses: 142 cases (2003?2007). To evaluate the sensitivity and specificity of abdominal computed radiography (CR) for the diagnosis of enterolithiasis in horses and to examine how these parameters are affected by the number and anatomic location of enteroliths and by gas distension of the gastrointestinal tract. Methods: Retrospective case series. Methods: Horses ? 1 year old that underwent abdominal CR and subsequent exploratory laparotomy or postmortem examination. Methods: 3 reviewers blinded to signalment, history, clinical signs, and diagnoses separately evaluated abdominal computed radiographs of horses included in th...
Influence of the uterine environment on the development of in vitro-produced equine embryos. The necessity for early interaction between the embryo and the oviductal and/or uterine environment in the horse is reflected by several striking differences between equine embryos that develop in vivo and those produced in vitro. Better understanding of the salient interactions may help to improve the efficiency of in vitro equine embryo production. In an initial experiment, cleavage-stage in vitro-produced (IVP) equine embryos were transferred into the uterus of recipient mares that had ovulated recently to determine whether premature placement in this in vivo environment would improve subse...
