The study included 57 synovial fluid samples from horses with presumed synovial infection and a control group consisting of 31 synovial fluid samples originating from clinically normal horses and horses with aseptic synovial inflammation. All samples were analysed by 16S PCR with reverse line blot (RLB) hybridisation. Synovial fluid samples were cultured using conventional agar plate methods (APM) and/or blood cultur...
Identification and seasonal distribution of airborne fungi in three horse stables in Italy. Fungal agents are responsible for a variety of respiratory diseases both in humans and animals. The nature and seasonal variations of fungi have been investigated in many environments with wide ranging results. The aims of the present report were (i) to evaluate the quality and magnitude of exposure to airborne fungi in three differently structured equine stalls (open air, partially and completely enclosed buildings) during a one-year period, using an air sampling technique and (ii) to compare the distribution and frequency of fungal species, with regards to these different environments. Air s...
[Farmer’s lung disease caused by straw or hay? Case report]. A young woman was admitted to Akranes Regional Hospital because of dyspnea, fatigue and fever. She was found to have bilateral pneumonia but etiology was not found. She was treated with antibiotics with good resolution and was discharged after eight days from the hospital. Four weeks later she noticed rapidly progressive dyspnea and was found to be hypoxemic, and to have restrictive spirometry and diffuse interstitial changes on chest radiography. Computerized tomography of the lungs showed diffuse ground glass changes. Transbronchial biopsies from the lungs showed numerous small granulomas. S...
Fracture, luxation, and chronic septic arthritis of the temporomandibular joint in a juvenile horse. This case report describes chronic sepsis of the right temporomandibular joint in a juvenile horse. Diagnostic work-up included physical examination, radiography, and computed tomography. Humane euthanasia was indicated due to the chronicity of the condition, prognosis, and financial constraints.
Fertility in the mare after repeated transvaginal ultrasound-guided aspirations. Ovum pick-up (OPU) by transvaginal ultrasound guided aspiration (TUGA) is a procedure applied in equine-assisted reproduction programs such as oocyte transfer and in vitro embryo production. Despite a large number of studies reporting that it is a repeatable and safe technique, little information is available about the effect of repeated punctures on fertility of mares. Moreover, even if flushing follicles improves the oocyte recovery rate, to our knowledge the efficiency of flushing estrous and diestrous follicles has not been evaluated. The aims of the present study were (1) evaluate if repe...
Linear kinematics at take-off in horses jumping the wall in an international Puissance competition. Sagittal plane SVHS video recordings (50 Hz) were made of horses jumping the wall at an international Puissance competition. Video sequences were manually digitized and six kinematic variables at take-off were analyzed. Nine horses started the competition with the fence height at 1.80 m, and two horses attempted the fence in the fifth and final round with the fence height at 2.27 m. For successful performances, fence height was correlated with the following take-off variables: vertical velocity of the centre of mass (r = 0.45, p = 0.03); height of centre of mass (r = 0.44, p = 0.04); distance ...
Chip fractures from the distal lateral trochlear ridge of the talus of a quarter horse gelding: a veterinary medicine clinical report. An eighteen-month old quarter horse gelding was diagnosed with chip fractures from the distal lateral trochlear ridge of the talus. The horse presented with the symptom of persistent synovitis. The diagnosis was based on radiographic evidence. The horse was treated initially with arthroscopic surgery. He was given a non-steroidal anti-inflammatory agent, and a chondroprotective agent to prevent further damage to, and aid in the healing of, the damaged joint.
Sex reversal syndrome (64,XY; SRY-positive) in a mare demonstrating masculine behaviour. A 5-year-old Thoroughbred mare was subjected to cytogenetic and molecular analysis because of infertility and masculine behaviour. Chromosome studies, including painting with the whole X chromosome specific probe, revealed a male chromosome complement (64,XY). The PCR amplification of the SRY and ZFY genes showed the presence of both those genes, while the endocrinological study demonstrated a high level of testosterone (9.7 nmol/l). Sequencing of the SRY gene (1121 bp), comprising also 5'- and 3'-UTRs, did not reveal any differences when compared with the sequence of normal stallions. It was ...
Natural infection of a horse with Fascioloides magna. A 25-year-old Quarterhorse mare was euthanized for a variety of medical reasons. At necropsy, 7 liver flukes, identified as Fascioloides magna, were recovered from the liver. This is the first report of F. magna in a horse.
[Verrucous pastern dermatitis syndrome in heavy draught horses. Part II: Clinical findings]. In the present field study the skin of the feet of 37 heavy draught horses of different breeds showing verrucous pastern dermatitis was examined clinically. Included were the degree of severity of the disease and the prevalence of anatomically normal structures associated with the skin: fetlock tufts of hair ("feathering"), ergots, chestnuts, bulges in the pastern region, cannon circumference. Each horse was examined for Chorioptes sp. skin mites. Information was also collected on the development of the skin alterations and housing conditions and feeding. These individual data were correlated ...

Aversive conditioning of periodic spontaneous erection adversely affects sexual behavior and semen in stallions. Periodic spontaneous erection and penile movements known as masturbation (SEAM) occur normally at approximately 90 min intervals in awake equids. SEAM in horses has traditionally been misunderstood by many horsemen as aberrant behavior that should be eliminated. Accordingly, it is not uncommon for trainers of performance stallions or managers of breeding stallions to punish SEAM in an attempt to eliminate the behavior. Previous clinical observations and preliminary unsystematic trials had suggested that attempts to stop stallion SEAM may lead to an increase rather than a decrease in SEAM, and ...
Temporal folate status during lactation in mares and growth in foals. To identify changes in folate status of mares and foals during lactation and growth, respectively. Methods: 20 Thoroughbred mares and foals. Methods: Pregnant mares, and following foaling the same mares with their foals, were maintained on mixed grass-legume pasture and fed either a traditional dietary supplement rich in sugar and starch (SS) or a dietary supplement high in fat and fiber (FF). Blood samples were collected monthly from mares and foals up to 6 months after foaling. Total folate concentration in feed and forage was determined. Analyses of plasma folate, RBC folate, plasma homocys...
Effect of a silicone-containing dressing on exuberant granulation tissue formation and wound repair in horses. To determine the effect of a silicone dressing on the rate and quality of repair of limb wounds and compare microvascular occlusion and apoptosis in wounds treated with the silicone dressing and those treated with a conventional dressing in horses. Methods: 5 horses. Methods: Horses received two 6.25-cm2 wounds on each metacarpus. Ten wounds were treated with a silicone dressing; the other 10 were treated with a control dressing. Quality of repair and wound size were evaluated at each bandage change. Time to healing and the number of excisions of exuberant granulation tissue were recorded. Bio...
Aspergillosis in mammals and birds: impact on veterinary medicine. Aspergillosis is relatively uncommon in mammals, but dogs, horses, cows and dolphins are susceptible. On the other hand, aspergillosis is a major cause of mortality in birds. This paper provides an overview of the manifestations of this disease in these animals. Treatment options are still lacking, but the increased incidence of the disease in humans has led to increased study, which may benefit both human and veterinary medicine.
Datura contamination of hay as the suspected cause of an extensive outbreak of impaction colic in horses. Datura poisoning of horses is extensively reviewed. An outbreak of intractable impaction colic affecting 18 of 83 horses was stopped by withdrawing dried tef hay contaminated with young Datura plants. The dried, botanically identified Datura stramonium and D. ferox contained respectively 0.15% mass/mass (m/m) hyoscyamine as well as 0.16% m/m hyoscine (scopolamine) and only hyoscine at a concentration of 0.11% m/m. Immature, unidentifiable plants resembling D. stramonium, contained 0.14% m/m and 0.12% m/m of the 2 respective tropane alkaloids. The outbreak was characterised by protracted and re...
Tracheal perforation managed by temporary tracheostomy in a horse. Tracheal trauma with resultant rupture is uncommonly reported in veterinary literature. We report the case of a 16-year-old Thoroughbred gelding that sustained a 1 cm longitudinal perforation of the dorsal tracheal membrane in the proximal cervical region. The horse subsequently developed dyspnoea due to acute upper respiratory obstruction secondary to severe emphysema of the guttural pouches. A temporary tracheostomy caudal to the site of tracheal perforation was performed under local anaesthesia. This procedure helped relieve the upper airway obstruction and aided resolution of the injury by...
Carpal collateral ligament desmopathy in three horses. The radiographic and ultrasonographic findings in three horses with severe damage to the collateral ligaments of the carpus, associated with degenerative joint disease, are described. The horses remained lame despite prolonged rest and medical management, primarily because of the progression of the joint disease. Ultrasonography was found to be an accurate method for diagnosing the injury to the ligaments and is recommended as part of a routine examination in suspected carpal injuries.
[The issue of continuity in ancient horse medicine: the treatment of diseases of the extremities described in the Kităb al-furŭsĭya wa-l-baytara by Muhammad ibn Ya’qŭb ibn ahĭ Hizăm al-Huttulĭ]. Since the late 9th century, scientific literature in Arabian language, based on the translation and compilation of works of the Classical, Persian and Indian culture considerably increased. This also applies to the field of veterinary medicine, as is illustrated by a number of hippological and hippiatric treatises. Affinities between texts on horse medicine in Antiquity and in Arabian literature have been mentioned by philologists, but the degree of dependence on classical texts could not be verified due to the lack of translations of the Arabian texts. In this respect, the oldest available te...
