Topic:Veterinary Care
Veterinary care in horses encompasses the medical and preventive measures taken to maintain and improve the health and well-being of equine patients. It includes a wide range of practices such as routine health examinations, vaccinations, dental care, parasite control, and management of injuries and diseases. 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.
Risk factors for Thoroughbred racehorse fatality in flat starts in Victoria, Australia (1989-2004). Research into risk factors specific for fatality in flat racing should be focused at a regional level as the risk factors may differ among countries and even regions within countries. Objective: To identify risk factors for fatality of Thoroughbred racehorses in flat starts on all racecourses in Victoria, Australia between 1989 and 2004. Methods: Fatalities comprised all horses that died during or immediately after a flat race or official flat trial, and all horses that were subjected to euthanasia within 24 h of an event in which an injury was sustained. The retrospective study involved 283 c...
Assessment of mild hindlimb lameness during over ground locomotion using linear discriminant analysis of inertial sensor data. Hindlimb lameness is common and can be difficult to diagnose or quantify in evaluating response to nerve blocks. An objective measure of lameness can also be used to evaluate the effectiveness of the treatment's contribution to evidence-based medicine. The inertial sensor system can be used to capture 6 degree of freedom movement during over ground locomotion and here was used to quantify tuber coxae movement in nonlame and lame horses. Objective: Tuber coxae movement is useful for discriminating between nonlame and lame horses. Objective: To measure left and right tuber coxae movement in lame...
Concurrent atypical myopathy and equine dysautonomia in two horses. This report concerns 2 horses that suffered typical clinical signs of atypical myopathy (AM) and equine grass sickness (EGS) concurrently. Clinical details and pathological lesions of the cases are described. EGS and AM are relatively rare diseases and the concurrency of the diseases in the same animals is therefore considered unlikely to be a coincidence. However, it is not suggested that the evidence shows a common aetiology but rather the existence of common predisposing causes.
Epidemiology of training and racing injuries. The management and prevention of racehorse injuries have been
studied for many years but it is only in the last decade that
quantitative epidemiological techniques have been applied to
racehorse injury and fatality (Estberg et al. 1995, 1996, 1998a,b;

Decreased radiopharmaceutical uptake (photopenia) in delayed phase scintigraphic images in three horses. Decreased radiopharmaceutical uptake, photopenia, in delayed phase scintigraphic images is recognized in people but has only been reported rarely in horses. We describe three horses with septic osteitis, bone sequestrum formation, or distal limb thrombosis that had photopenia of the affected extremity. Photopenia may indicate the presence of ischemia and can be used to facilitate clinical decision making and prognosis assessment
Molecular diagnosis of equid summer sores. Equine cutaneous habronemosis, also known as "summer sores", is a parasitic infection caused by larvae of Habronema microstoma and Habronema muscae (Nematoda, Spirurida) released by dung-inhabiting fly vectors on abraded skin, skin wounds or muco-cutaneous transition sites. Larvae induce a local inflammatory reaction characterised by itching, granulomatous, ulcerated and, often non-healing, lesions. The diagnosis of summer sores may be unreliable mainly because of the limits of clinical and microscopic examination. The applicability of a semi-nested PCR assay developed for the diagnosis of gas...
Outbreak of Q fever associated with a horse-boarding ranch, Colorado, 2005. Coxiella burnetii is a bacterium located worldwide that can cause Q fever when inhaled. We describe an outbreak of Q fever associated with a horse-boarding ranch that had acquired two herds of goats. We conducted case finding and cohort studies among persons who boarded horses on the ranch and ranchers and among residents in the surrounding community, and conducted sampling of the goats and environment, to determine risk factors for infection and guide public health interventions. Sixty-six ranchers and persons who boarded horses on the ranch were interviewed; 62 (94%) were not professional ra...
Flow cytometric probing of mitochondrial function in equine peripheral blood mononuclear cells. The morphopathological picture of a subset of equine myopathies is compatible with a primary mitochondrial disease, but functional confirmation in vivo is still pending. The cationic dye JC-1 exhibits potential-dependent accumulation in mitochondria that is detectable by a fluorescence shift from green to orange. As a consequence, mitochondrial membrane potential can be optically measured by the orange/green fluorescence intensity ratio. A flow cytometric standardized analytic procedure of the mitochondrial function of equine peripheral blood mononuclear cells is proposed along with a critical...
Detection and quantification of low levels of benzoylecgonine in equine urine. Cocaine (COC) is a highly addictive plant alkaloid expressing strong psychostimulatory effect. It has no medical use in equine veterinary practice. The contamination of the environment with cocaine such as its presence on the US paper currency has been reported few times. There are anecdotal reports of low benzoylecgonine (BE) concentrations (usually much less than 100 ng/mL) being found in urine of race horses. In order to protect horsemen against harsh penalties associated with the presence of trace amounts of BE in horse urine as a result of environmental contamination, in February 2005 the...
Adenosine receptor modulation: potential implications in veterinary medicine. Adenosine is a purine nucleoside whose concentration increases during inflammation and hypoxia and the many roles of this molecule are becoming better understood. Increased reactivity to adenosine of the airways of asthmatic but not of normal subjects underlines the role of adenosine in airway inflammation. The identification and pharmacological characterisation of different adenosine receptors have stimulated the search for subtype-specific ligands able to modulate the effects of this molecule in a directed way. Several compounds of different chemical classes have been identified as having po...
Parasite control practices on Swedish horse farms. Virtually all horses are infected with helminth parasites. For some decades, the control of parasites of Swedish horses has been based on routine treatments with anthelmintics, often several times per year. Since anthelmintic resistance is becoming an increasing problem it is essential to develop more sustainable control strategies, which are adapted to different types of horse management. The aim of this study was to obtain information on practices used by Swedish horse owners for the control of endoparasites. Methods: A questionnaire with 26 questions about management practices and parasite ...
Comparative examination of percussional and echocardiographic determination of the cardiac dullness area in healthy horses. Since percussion started to be a method forgotten and not trusted by many practitioners, the aim of the study was to demonstrate whether this procedure could deliver exact data if done accurately and by a practised examiner. The trial presented here included 31 healthy warm-blooded horses. Percussion of the area of cardiac dullness and then echocardiographic imaging of the same region were performed. To obtain the relevant measurement points, the 4th and 5th intercostal spaces (ICS) were used on the left and the 4th ICS on the right side. On the left side, the dorsal border of cardiac dullness...
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...
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...
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. La langue semblait a...
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). Serum clinical chemistry results included increased aspartate transaminase, alkaline phosphatase, and gamma-glutamyltransferase activities. A presumptive diagnosis ...
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 ...
