Haptoglobin baseline value in jennies and the effect of ovariectomy on its serum concentration. The study was conducted to determine the baseline concentration of serum haptoglobin (Hp) in jennies during the breeding and nonbreeding season and to evaluate the effects of ovariectomy on serum Hp concentrations in jennies. Eighteen adult jennies were divided in three groups: nine jennies (OVA) were ovariectomized using laparoscopic surgery, six jennies (LAP) were exploratory examined by laparoscopic surgery, and three jennies were used as a control group. Blood samples were collected from the animals at Day -6, -2, -1, 0, 1, 2, 5, 8, 15, 22, 29 and 36 of surgery. Serum samples were analyzed...
Equine insect bite hypersensitivity: what do we know? Insect bite hypersensitivity (IBH) is an allergic dermatitis of the horse caused by bites of insects of the genus Culicoides and is currently the best characterized allergic disease of horses. This article reviews knowledge of the immunopathogenesis of IBH, with a particular focus on the causative allergens. Whereas so far hardly any research has been done on the role of antigen presenting cells in the pathogenesis of IBH, recent studies suggest that IBH is characterized by an imbalance between a T helper 2 (Th2) and regulatory T cell (T(reg)) immune response, as shown both locally in the skin...
Do you know your equine practice clients? A healthy group of loyal clients is of the utmost importance for a healthy practice.Knowing the clients’ expectations and making every effort to exceed them when clients meet with the veterinarian or visit the clinic will result in continued client satisfaction. Clients will show loyalty to a veterinarian when they perceive that the care provided to them suits them and their animal and exceeds their expectations.
Ambulatory equine practice management. The horse owner not only expects outstanding care for their horse; they also recognize and appreciate a well-run equine practice. They expect their veterinarian to show up on time for appointments; they expect to receive decipherable invoices and statements on a regular basis and they appreciate an assistant who enhances the services that their veterinarian provides. A well-managed ambulatory equine practice supports the ideals of both high standards of care and mobility. In fact, a poorly managed practice will ultimately impact the care that an equine veterinarian attempts to provide the hors...
Local anesthesia and hydro-distension to facilitate cystic calculus removal in horses. To report a technique for improving surgical access to the bladder for removal of cystic calculi in male horses. Methods: Retrospective case series. Methods: Geldings (8) with cystic calculi. Methods: After catheterization of the bladder through the penis, 100 mL 2% lidocaine hydrochloride solution was instilled. After 10 minutes, the bladder was distended with sterile, warmed Hartmann's solution to a pressure of ≈ 40 cm H(2) O, using gravity feed. This was left in place until abdominal access was gained at surgery, then the fluid siphoned off via the catheter. Results: Calculi were 3-11 cm ...
Lameness and performance evaluation in ambulatory practice. Lameness and performance evaluation can be one of the most rewarding aspects of equine veterinary practice. There is a misconception that it depends on new sophisticated and expensive diagnostic modalities, when the reality is that knowing where and when to use these modalities form the real art of equine lameness practice. The most expensive ultrasound machine in the world is not very diagnostic if applied to the wrong limb. The art of lameness practice is vested in knowledge of horsemanship, an understanding of anatomy and function, and inquiring senses to sort out what the horse and his han...
Endoscopic-assisted electrohydraulic shockwave lithotripsy in standing sedated horses. To report use of transendoscopic electrohydraulic shockwave lithotripsy for fragmentation of urinary calculi in horses. Methods: Case series. Methods: Male horses (n = 21). Methods: Fragmentation of cystic calculi (median, 6 cm diameter; range, 4-11 cm diameter) was achieved by transurethral endoscopy in standing sedated horses using an electrohydraulic shockwave fiber introduced through the biopsy channel of an endoscope. The fiber was advanced until it contacted the calculus. Repeated activation of the fiber was used to disrupt the calculus into fragments <1 cm diameter. Visibility within...

To describe and measure histologic features of midcarpal joint cartilage defects in Thoroughbreds and evaluate the influence of early conditioning exercise on defect development. Methods: 24 midcarpal joints from twelve 18-month-old Thoroughbreds. Methods: Midcarpal joints from 12 horses (6 exercised spontaneously at pasture only and 6 given additional conditioning exercise beginning at a mean age of 3 weeks were evaluated. Gross cartilage defects were assessed histologically. Third and radial carpal bones were categorized with regard to the presence or absence of calcified cartilage (CC) abno...
A new clinical approach: use of blood-derived stem cells (BDSCs) for superficial digital flexor tendon injuries in horses. In this study, we present an innovative therapy using stem cells that were obtained from the peripheral blood of racehorses affected by uninduced superficial digital flexor tendon (SDFT) injuries. Methods: Blood-derived stem cells (BDSCs) were generated from the blood samples of three horses in the presence of macrophage colony-stimulating factor (M-CSF). The racehorses received a single autologous BDSC treatment, which resulted in the successful repair of the tendons injuries. Results: The results demonstrated that the BDSCs injection into the damaged tendon stimulated the regeneration of nor...
Effect of sample storage on blood crossmatching in horses. Blood samples banked for up to 1 month are typically used to perform pretransfusion testing in humans and small animals, but this has not been validated using blood from horses. Objective: Compatibility of equine blood samples is repeatable using fresh samples, and reproducible using donor blood samples stored for up to 4 weeks. Methods: Six healthy adult horses. Methods: Randomized, blinded experimental study. Immunologic compatibility of the blood of all horses was assessed using a major and minor saline agglutination and hemolysin crossmatch using blood samples refrigerated for 0-4 weeks an...

The aim of this study was to compare sensitivity of ultrasound and optical coherence tomography (OCT) techniques for the evaluation of the integrity of spontaneously repaired horse cartilage. Articular surfaces of horse intercarpal joints, featuring both intact tissue and spontaneously healed chondral or osteochondral defects, were imaged ex vivo with arthroscopic ultrasound and laboratory OCT devices. Quantitative ultrasound (integrated reflection coefficient (IRC), apparent integrated backscattering coefficient (AIB) and ultrasound roughness index (URI)) and optical parameters (optical refle...
Genetic mapping of recurrent exertional rhabdomyolysis in a population of North American Thoroughbreds. Recurrent exertional rhabdomyolysis is a heritable disorder that results in painful skeletal muscle cramping with exercise in up to 10% of all Thoroughbred racehorses. Here, we report a genome-wide association study with 48 282 SNPs analyzed among 48 case and 37 control Thoroughbreds. The most significant SNPs spanned approximately 13 Mb on ECA16, and the P-value of the most significant SNP after correcting for population structure was 8.0 × 10(-6) . This region on ECA16 was further evaluated by genotyping 247 SNPs in both the initial population and a second population of 34 case and 98 contr...
Seroprevalence of Neospora spp. in horses in South of Iran. Neospora caninum, an apicomplexan protozoan parasite, is recognized as a major cause of abortion in cattle. However, limited information is presently available on the seroprevalence of Neospora antibodies in horses worldwide. The aim of the present study is to determine serological prevalence of Neospora infection in horses in Iran. Blood samples were obtained from 200 horses and tested for serum antibodies against Neospora spp. by the Neospora modified direct agglutination test (N-MAT). Antibodies were found in 64 (32%) horses being tested with titers of 1:80. This is the first serological su...
Innovative approach to investigating the microstructure of calcified tissues using specular reflectance Fourier transform-infrared microspectroscopy and discriminant analysis. Although bone fracture has become a serious global health issue, current clinical assessments of fracture risk based on bone mineral density are unable to accurately predict whether an individual is likely to suffer a fracture. There is increasing recognition that the chemical structure and composition, or microstructure, of mineralized tissues has an important role to play in determining the fracture resistance of bone. The objective of this preliminary study was to evaluate the use of specular reflectance Fourier transform infrared (SR FT-IR) microspectroscopy in conjunction with discriminan...
Reliability of high- and low-field magnetic resonance imaging systems for detection of cartilage and bone lesions in the equine cadaver fetlock. To determine the reliability of 2 magnetic resonance imaging (MRI) systems for detection of cartilage and bone lesions of the equine fetlock. Objective: To test the hypotheses that lesions in cartilage, subchondral and trabecular bone of the equine fetlock verified using histopathology can be detected on high- and low-field MR images with a low incidence of false positive or negative results; that low-field images are less reliable than high-field images for detection of cartilage lesions; and that combining results of interpretation from different pulse sequences increases detection of cartil...
Towards an inhalative in vivo application of immunomodulating gelatin nanoparticles in horse-related preformulation studies. Delivering active ingredients using biocompatible and biodegradable carriers such as gelatin nanoparticles (GNPs) to the lung constitutes a promising non-invasive route of administration. However, the pulmonary delivery of nanoparticle-based immunotherapy is still a field that requires more clarification. In this study, GNPs loaded with cytosine-phosphate-guanine oligodeoxynucleotides (CpG-ODN)-loaded and plain GNPs were aerosolised either by a conventional pressured metered dose inhaler (pMDI) or by active or passive vibrating-mesh (VM) nebulisers. GNP sizes after nebulisation by active and p...
Pyrethroid tolerance in the chewing louse Bovicola (Werneckiella) ocellatus. Equine pediculosis is a significant health and welfare issue, particularly in elderly and chronically debilitated animals. Currently infestation is controlled predominantly using topically applied pyrethroid insecticides, allowing limited scope for the rotation of drugs and increasing the risk of selection for resistance. Here the insecticidal efficacies of two pyrethroid-based products against the louse Bovicola (Werneckiella) ocellatus collected from donkeys were examined in vitro. The products were cypermethrin (Deosect™, Pfizer Ltd., 5% (w/v) cypermethrin, cutaneous spray) and permethrin...
Elimination half-life of intravenously administered equine cardiac troponin I in healthy ponies. To date, no information is available on the true biological elimination half-life (T(1/2) ) of cardiac troponin I (cTnI) in the equine species. Such data are required to better evaluate the optimal time to acquire the cTnI sample following acute myocardial injury. Objective: To determine the T(1/2) of equine cTnI. Methods: Four healthy ponies received i.v. injections of recombinant equine cTnI. Plasma cTnI concentrations were measured with a point-of-care cTnI analyser at multiple time points after injection. Standard pharmacokinetic analysis was performed to establish the T(1/2) of cTnI. Resu...
Whip use by jockeys in a sample of Australian Thoroughbred races–an observational study. The use of whips by jockeys is an issue. The current study viewed opportunistic high-speed footage of 15 race finishes frame-by-frame to examine the outcomes of arm and wrist actions (n = 350) on 40 horses viewed from the left of the field. Any actions fully or partially obscured by infrastructure or other horses were removed from the database, leaving a total of 104 non-contact sweeps and 134 strikes. For all instances of arm actions that resulted in fully visible whip strikes behind the saddle (n = 109), the outcomes noted were area struck, percentage of unpadded section making conta...
Reproduction in ambulatory practice. The value of providing equine reproductive services in ambulatory setting is well established. Ambulatory practice has been, and will most likely continue to be, the primary provider of equine reproductive veterinary services. The limitations for performing various reproductive procedures in an ambulatory setting are those imposed by the amount of equipment and supplies that must be brought to the patient, as well as those imposed when procedures require additional assistance. This is analogous to human medical care: the ambulance cannot substitute for a hospital but it can certainly provide s...
Proliferation of equine bone marrow-derived mesenchymal stem cells in gelatin/β-tricalcium phosphate sponges. A three dimensional scaffold is essential in mesenchymal stem cells (MSCs) delivery in cell-based therapy for facilitating cell adherence, migration, proliferation, and differentiation. The objectives of this study were to evaluate the possibility of β-tricalcium phosphate incorporated gelatin sponges (Gelatin/β-TCP sponge) as scaffolds for equine MSCs and to examine the effects of seeding density and seeding method on the proliferation of equine MSCs in the Gelatin/β-TCP sponges. Mononuclear cells and MSCs isolated from bone marrow were seeded into Gelatin/β-TCP sponges at different densi...
Equine wellness care in ambulatory practice. Clients want dependable veterinary care and to understand how the services will benefit and meet their horse’s needs. Wellness visits provide ambulatory practitioners with great opportunities to strengthen the doctor-client-patient bond; effective communication with clients during wellness visits, where new literature or facts can be presented, can offer opportunities for demonstrating the value of having the veterinarian maintain a primary role in disease control. The criteria for selecting vaccines, interpreting FECs, and diagnosing dental pathology require the continued need for veterinar...
