Omental leiomyoma in a male adult horse. A well-circumscribed mass 70 x 35 x 28 cm in size and 41 kg in weight was detected at necropsy in a male adult horse within the omentum major without any association to the gastrointestinal tract. The tumor consisted of multiple white-to-yellow lobules and displayed a firm consistency. In addition, multiple cysts filled with blood-like fluid, and multifocal areas of necrosis were observed. Histologically, the mass consisted of slightly pleomorphic spindloid-shaped cells arranged in interlacing bundles containing elongated nuclei with blunt ends. The majority of tumor cells revealed a positive ...
A single subcutaneous administration of buserelin induces ovulation in the mare: field data. The aim of the present study, was to evaluate whether a single subcutaneous administration of the GnRH analogue buserelin could induce ovulation in the mare during the breeding season. Two studies were carried out under field conditions. In Experiment 1, 90 cycles of trotter mares aged 2-7 years, were assigned to a buserelin group (Bus1) or to a control group (Control), in the presence of a >/=35 mm pre-ovulatory follicle, with uterine oedema and a relaxed cervix. Ten mares were assigned to the two groups for 32 cycles in Bus1 and 52 cycles in Control, two mares received only Bus1 for three...
Comparative study of doramectin and fipronil in the treatment of equine chorioptic mange. In equids, chorioptic mange is a common dermatitis for which there are no licensed medications in the uk. Doramectin and fipronil are licensed for the control of ectoparasites in other species and were evaluated for the treatment of 17 cases of chorioptic mange in 13 equids. Equids were included if clinical findings were indicative of chorioptic mange, chorioptes mites were positively identified and concurrent disease that could affect response to disease was not evident. A random number table was used to allocate subjects to receive doramectin (group D, eight animals) or fipronil (group F, ni...
Glossitis and tongue trauma subsequent to administration of an oral medication, using an udder infusion cannula, in a horse. A 10-year-old gelding was presented with a tongue that had swelled immediately after oral administration of oxfendazole, using an udder infusion cannula. The tongue appeared to have been punctured inadvertently. The horse recovered after treatment with intravenous fluid, antibiotics, and anti-inflammatory drugs. Administering oral medication by this method should be discouraged. Un cheval hongre âgé de 10 ans a été présenté avec une langue devenue tuméfiée immédiatement après l’administration orale d’oxfendazole à l’aide d’une canule à infusion du pis.

Use of matrix metalloproteinases 2 and 9 and white blood cell counts in monitoring the treatment and predicting the survival of horses with septic arthritis. Thirty-nine samples of synovial fluid were collected from the joints of 32 horses with suspected septic arthritis and 39 samples were collected from horses euthanased for non-orthopaedic conditions. The white blood cell counts (WBCC) were determined and the pro and active forms of matrix metalloproteinases (MMPs) 2 and 9 were measured by gelatin zymography and image analysis in each sample. The initial measurements of the ratio of proMMP9:proMMp2 and WBCC were good prognostic indicators of the survival of the horses. There was no significant relationship between the interval between the injury...
Abortion in a thoroughbred mare associated with an infection with avirulent Rhodococcus equi. An eight-year-old thoroughbred mare with no previous history of illness aborted a fetus at 196 days of gestation, and its internal tissues were examined immunohistologically and bacteriologically. The placenta was not examined, but specimens of the intrauterine fluids and the dam's faeces were collected four days after the abortion and examined bacteriologically. No significant histological lesions were found in the fetus but the amnion and the umbilical cord were oedematous and had petechial haemorrhages. Rhodococcus equi was isolated in pure culture from the lung, heart and stomach contents ...
Molecular diagnosis of certain nematode infections can save life and beauty, and preserve breeds of socially relevant and sporting animals. The recognition that the health and welfare of some humans are improved through contact and relationships with animals is now established. Two commonly recognized assistance animals are dogs and horses. Both provide therapeutic benefits to humans with some physical and mental illnesses and both assist people with disabilities. Moreover, the public and scientific attention to the health and conservation of many animal breeds is also increasing worldwide. In the past few years, two potentially life-threatening nematode infections that can induce tumours or tumour-like masses in canids and equids...
Dose to persons assisting voluntarily during X-ray examinations of large animals. Pet owners often assist voluntarily while their pets are being X-rayed during a medical examination. Medical staff members occupationally exposed to radiation are monitored regularly, as they wear personal dosemeters, whereas no dose measurements are carried out on voluntarily assisting persons, as measurements are both cost- and time-intensive. However, the dose limits prescribed in the German radiation protection regulations have to be observed for these volunteers as well. To assist the legislator in deciding whether the German regulation should be changed so that in future the dose of volu...
Pelger-Huët anomaly in an Arabian horse. A 9-year-old Arabian mare was evaluated for a 7-day history of malaise. Results of a CBC included a leukocyte concentration within the reference interval (8.4 x 10(3)/microL, reference interval 6.0-14.0 x 10(3)/microL) with an apparent degenerative left shift (segmented neutrophils 1.2 x 10(3)/microL, reference interval 2.5-7.5 x 10(3)/microL; hyposegmented neutrophils 1.8 x 10(3)/microL, reference interval 0.0-0.2 x 10(3)/microL).

Risk factors for influenza infection in vaccinated racehorses: lessons from an outbreak in Newmarket, UK in 2003. Between March and May 2003, clinical equine influenza was confirmed among vaccinated racehorses in Newmarket, UK. A particular feature was that 2-year-old horses were apparently less susceptible than older animals. Statistical analyses comparing infected and non-infected animals showed the unusual, apparently counter-intuitive inverse age effect was principally explained by more recent vaccination among younger animals, despite broadly equivalent antibody levels between age groups. There was novel evidence for sexual dimorphism in susceptibility to infection and data supported the hypothesis t...
West Nile virus outbreak detection using syndromic monitoring in horses. Recent outbreaks of West Nile virus-associated (WNV) diseases, both in the old World and Americas, underline the importance for early warning systems that rapidly identify emerging and re-emerging diseases and thus help in their control. Traditional approaches of disease monitoring become less reliable and increasingly costly when used for rare health-related events, such as WNV outbreaks in southern France. The objective of this work was to discuss methodological issues related to syndromic monitoring of WNV-associated disease in Camargue horses by veterinary practitioners. Tracking cases of ...
Evaluation of a turbidimetric immunoassay for measurement of plasma IgG concentration in foals. To validate a turbidimetric immunoassay (TIA) for measurement of plasma IgG concentrations in foals. Methods: 36 foals. Methods: Blood samples were collected from foals before suckling and at 12 and 24 to 36 hours after birth. Plasma IgG concentrations were determined via a commercial single radial immunodiffusion (RID) assay. By use of goat anti-equine IgG antiserum and a spectrophotometer, a TIA was developed to measure plasma and serum IgG concentrations; the percentage light transmission was calibrated against RID assay-determined IgG concentrations. Assay repeatability and effects of seri...
Validation of quantitative polymerase chain reaction assays for measuring cytokine expression in equine macrophages. The study of the equine immune system and inflammatory responses, by measuring cytokine expression, can provide important insight into disease pathogenesis in the horse. A set of quantitative real-time polymerase chain reaction (QPCR) assays for the equine cytokines IL-1alpha, IL-1beta, IL-6, IL-8 and TNF-alpha were validated using QPCR primers and probes which were generated for the equine IL-1alpha, IL-1beta, IL-6, IL-8, TNF-alpha and 18S genes. Amplification efficiency, intra-assay and inter-assay variation were determined using 10-fold dilutions of plasmid for each gene. Under these condit...

Equine’s Cushing’s Disease: A Clinical Update. The Department of Pharmacology at the North Carolina State University College of Veterinary Medicine is currently conducting stability studies of oral suspensions of pergolide for the treatment of Cushing's disease. While those results are not available at this time, this paper summarizes the results of a literature search on possible clinical treatments for equine Cushing's and is intended to provide insight into the pathophysiology of the disease. Pharmacological options for treatment of equine Cushing's are discussed.
Tail docking in horses: a review of the issues. Routinely performed painful procedures are of increasing interest and, in 2001 (Royal Order, May 17), Belgium prohibited docking in several vertebrates including horses. In 2004, opponents to this decision submitted a Bill (Doc51 0969/001) to Parliament, intending to obtain derogation for Belgian draught horses, which were traditionally docked. The Animal Welfare Council of Belgium, an official body advising the Minister of Public Health, was asked to evaluate this complex question, including biological, ethical and socio-economic aspects, on the basis of the available peer-reviewed studies. I...
Influence of fatty acid composition in mammalian erythrocytes on cellular aggregation. The rheologic properties of red blood cells (RBC) are determined by humoral and cellular factors. Fatty acid composition of the RBC phospholipid bilayer is one factor influencing membrane fluidity this could affect RBC aggregation because of a higher bias of RBC deformability. The present investigation was performed to investigate a possible relationship between fatty acid composition and erythrocyte aggregation using animals with high RBC aggregation (horse and pig) and animals with immeasurable RBC aggregation (sheep). Horse and pig showed similar distribution of the four major components pa...

Equine laminitis: ultrastructural lesions detected 24-30 hours after induction with oligofructose. The pathology of equine laminitis has been well-documented 48 h after dosing with oligofructose when clinical lameness and lamellar disintegration is well advanced. Further analysis of the earliest lesions, by collecting lamellar samples at the first sign of foot lameness after oligofructose dosing is required in order to increase understanding of the disease. Objective: To investigate lamellar epidermal hemidesmosome damage and basement membrane dysadhesion by transmission electron microscopy (TEM). Methods: Eight clinically normal, mature Standardbred horses were divided randomly into 2 grou...
Interleukin-6 and tumour necrosis factor in synovial fluid from horses with carpal joint pathology. The carpal joints are common sites of traumatic arthritis and osteoarthritis (OA) in athletic horses. The pro-inflammatory cytokines interleukin (IL)-6 and tumour necrosis factor (TNF) may be of great importance in the development of intra-articular lesions. The aim of the present study was to investigate possible associations between synovial fluid levels of bioactive IL-6 and TNF and different types of joint lesions seen in traumatic arthritis and OA. Synovial fluid was collected from horses with carpal lameness immediately before arthroscopic surgery. Articular cartilage, synovial membranes...
Phylogeny of trichostome ciliates (Ciliophora, Litostomatea) endosymbiotic in the Yakut horse (Equus caballus). Ciliates of the subclass Trichostomatia inhabit the fermentative regions of the digestive tract of herbivores. Most available small subunit ribosomal RNA (SSrRNA) gene sequences of trichostomes are from species isolated from the rumen of cattle or sheep and from marsupials. No ciliate species endosymbiotic in horses has yet been analyzed. We have sequenced the SSrRNA genes of five ciliate species, isolated from the cecum and colon of four Yakut horses: Cycloposthium edentatum, Cycloposthium ishikawai, Tripalmaria dogieli, Cochliatoxum periachtum, and Paraisotricha colpoidea. Based on their mor...
