Nielsen MK, Baptiste KE, Tolliver SC, Collins SS, Lyons ET.Increasing levels of anthelmintic resistance in equine nematodes have led to recommendations of more sustainable anthelmintic treatment protocols with emphasis on parasite surveillance and diagnosis, rather than prophylactic calendar-based treatments. This requires knowledge of the diagnostic test performance of techniques for counts of eggs per gram of feces (EPG) as well as methods for culturing, counting and identifying third stage (L(3)) strongyle larvae per gram of feces (LPG). For horses, such information does not exist in the published literature. The aim of this study was to examine th...
Lyons ET, Tolliver SC, Kuzmina TA, Collins SS.Critical tests were performed in 2009 and 2010 in four 2-year-old horses naturally infected with internal parasites. The horses were from a herd (Farm MC) where reduced activity of ivermectin and moxidectin on small strongyles was demonstrated previously from EPG (eggs/gram of feces) data in field tests. Also, in critical tests in horses from the same herd, ivermectin was less effective on immature small strongyles in the lumen of the large intestine than when the drug was first marketed. The main interest in the present critical tests was to determine the efficacy of moxidectin (400 μg/kg) o...
Kim I, Cohen ND, Roussel A, Wang N.Gastric emptying studies are of great interest in human and veterinary medical research to evaluate effects of medications or diets for promoting gastrointestinal motility and to examine unintended side-effects of new or existing medications, diets, or procedures. Summarizing gastric emptying data is important to allow easier comparison between treatments or groups of subjects and comparisons of results among studies. The standard method for assessing gastric emptying is by using scintigraphy and summarizing the nonlinear emptying of the radioisotope. A popular model for fitting gastric emptyi...
Samper JC, Plough T.In the last decade, there has been a significant increase in the quality and commercial use of frozen equine semen. The emergence of new reproductive technologies, coupled with the high prices for an insemination dose from some stallions, the increasing costs of import and export and the marketing policies of stallion agents or owners in the sport horse industry has stimulated the fractionation of doses for insemination. Consequently, the sperm number and the volume of an insemination dose are significantly reduced. To deliver lower doses of sperm in lower volumes compared to the standard dose...
Serra M, Papakonstantinou S, Adamcova M, O'Brien PJ.The use of cardiac troponin (cTn), the 'gold-standard' biomarker of myocardial injury in humans, is growing in veterinary medicine and in animal safety studies, although there are differences in its application in animals. In this study six new assays for the marker were assessed in 619 animals of six different species (dog, cat, horse, cattle, rat and rabbit), in clinical and drug-safety studies. Healthy animals and clinical cases without cardiac disease served as controls. Several of the tested assays had poor analytic or diagnostic sensitivity and only one test was effective in all species ...

This device allowed recording of the extradural pressure profile and the transformation of pressure changes into an audible signal. Ex...
Frisbie DD, Lu Y, Kawcak CE, DiCarlo EF, Binette F, McIlwraith CW.Current autologous chondrocyte implantation (ACI) techniques require 2 surgical procedures: 1 for cell harvest and 1 for reimplantation of cultured cells. A 1-step procedure is more desirable. Objective: A 1-step surgical procedure using autologous cartilage fragments on a polydioxanone scaffold, or CAIS (cartilage autograft implantation system), in a clinically relevant defect (15-mm diameter) within equine femoral trochlea was compared with a 2-step ACI technique as well as with empty defects and defects with polydioxanone foam scaffolds alone. Methods: Controlled laboratory study. Methods: ...
Castagnetti C, Pirrone A, Mariella J, Mari G.The use of blood lactate concentration as an indicator of prognosis and disease severity has become a common practice in equine medicine, especially with the validation of handheld analyzers. However, few authors described lactate concentration in critically ill foals, and there are no published studies about the use of handheld analyzers in neonatal foals. In this study, for the first time in the equine neonate, we validated the Lactate Scout analyzer, both in healthy and in critically ill foals. The study also describes the normal range for blood lactate in 26 healthy neonatal foals during t...

Rovira S, Muñoz A.Echocardiographic values need to be established for each age and breed to be applied to equine medicine. The present research aims to describe echocardiographic measurements in Spanish fillies and colts of different age, to compare these values with those previously described for other equine breeds and to determine whether there is an influence of gender on echocardiographic measurements. Seventy unsedated and healthy Spanish foals of both sexes (39 females and 31 males) were divided into five age groups: A (22-60 days; n=15), B (61-90 days; n=13), C (91-180 days; n=18), D (181-270 days; n=12...
Schwint ON, Ueti MW, Palmer GH, Kappmeyer LS, Hines MT, Cordes RT, Knowles DP, Scoles GA.Antimicrobial treatment of persistent infection to eliminate transmission risk represents a specific challenge requiring compelling evidence of complete pathogen clearance. The limited repertoire of antimicrobial agents targeted at protozoal parasites magnifies this challenge. Using Babesia caballi as both a model and a specific apicomplexan pathogen for which evidence of the elimination of transmission risk is required for international animal movement, we tested whether a high-dose regimen of imidocarb dipropionate cleared infection from persistently infected asymptomatic horses and/or elimi...
Fachal MV, Furlan M, Clark R, Card CE, Chedrese PJ.The objective of this investigation was to clone and express the elk and horse common alpha-subunit and FSH beta-subunit cDNAs, and to produce recombinant FSH from both species in vitro. The RNAs extracted from elk and horse pituitary glands were reverse-transcribed and amplified by polymerase chain reaction. The cDNAs corresponding to both subunits of elk and horse were cloned into the expression vector pBudCE4.1 and transfected into CRL-9096 cells. Expression of both genes was determined in the transfected cells by Northern and Western blot analysis. Recombinant elk and horse FSH secreted in...
Haarhuis JC, Muijtjens AM, Scherpbier AJ, van Beukelen P.Interest in the areas of food animals (FA) and veterinary public health (VPH) appears to be declining among prospective students of veterinary medicine. To address the expected shortage of veterinarians in these areas, the Utrecht Faculty of Veterinary Medicine has developed an admissions procedure to select undergraduates whose aptitude and interests are suited to these areas. A study using expert meetings, open interviews, and document analysis identified personal characteristics that distinguished veterinarians working in the areas of FA and VPH from their colleagues who specialized in comp...
Koch TG, Berg LC, Betts DH.This paper provides a bird's-eye perspective of the general principles of stem-cell therapy and tissue engineering; it relates comparative knowledge in this area to the current and future status of equine regenerative medicine.The understanding of equine stem cell biology, biofactors, and scaffolds, and their potential therapeutic use in horses are rudimentary at present. Mesenchymal stem cell isolation has been proclaimed from several equine tissues in the past few years. Based on the criteria of the International Society for Cellular Therapy, most of these cells are more correctly referred t...
Lee S, Kyaw MT, Harada K, Kusakabe KT, Igase M, Sasaki N.Generally, most mesenchymal stem cells (MSCs) have lower pluripotency and limited differentiation potential than embryonic stem cells (ESCs). However, a small subpopulation of MSCs, called multilineage differentiating stress-enduring (MUSE) cells, exhibit pluripotency. MUSE cells express stage-specific embryonic antigen 3 (SSEA-3), a sphingoglycolipid. Here, we isolated and investigated the pluripotency of SSEA-3-positive MSCs (MUSE cells). Six thoroughbred horses were used as test subjects. MSCs were harvested from the bone marrow of the thoracic vertebrae under ultrasound guidance. Harvested...
Turcotte GK, O'Sullivan TL, Spence KL, Winder CB, Greer AL.Horses may travel for a variety of reasons, leading to potential exposure to pathogens. Typically, these movements are bidirectional with horses returning to their home facility, therefore also risking pathogen exposure to resident horses at home facilities. The Canadian National Farm and Facility Level Biosecurity Standard for the Equine Sector was designed to outline best practices for managing biosecurity at equestrian facilities, however, there is a gap between the implementation of these recommendations and the day-to-day operations of equestrian facilities. This study aimed to explore th...
Lai CS, Wong ASY, Wong KS, Wan TSM, Ho ENM.In the screening of prohibited substances (PS) in horse biological samples with gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/mass spectrometry (LC/MS) for doping control, an enormous number of chromatograms are generated. Reviewing these chromatograms to identify suspicious findings requires an extensive manual effort. Recent advancements in Artificial Intelligence (AI) enable its use to classify images into different categories. This can potentially be utilized to perform first-line analysis of chromatograms, which are usually displayed as images, by classifying them...
Roth SP, Liso G, Brehm W, Wagner B, Schnabel CL, Troillet A.The anti-inflammatory and regenerative effects of autologous conditioned serum (ACS) in joint-associated disorders are presumably mediated by the biomolecules it contains, such as cytokines and chemokines.

Tarillion M, Hertzsch R, Richter A.Since 28.01.2022, veterinary medicinal products must be used in accordance with the conditions of authorization (Regulation (EU) 2019/6, Article 106). This entails further restrictions on therapeutic freedom, e. g., with regard to dose deviations. To date, there is no data available in equine medicine on the scope of off-label use as any use deviating from the expert information for antibiotics, on the basis of which the feasibility of implementing the new regulations in Germany can be assessed.To collect data on the off-label use of antibiotics, a Germany-wide anonymous online survey was th...
Hellige M, Geburek F.Diagnostic imaging is an important part of the diagnostic approach in equine spinal ataxia especially with the cervical spine being commonly involved. The spinal cord may be affected by a variety of conditions including cervical vertebral malformations, osteoarthritis of the articular process joints or less commonly neoplasia. Advanced imaging techniques such as myelography are more accurate in diagnosing spinal cord compression and may be performed under general anesthesia in neutral, flexed and extended positions of the cervical spine. The use of ultrasound is non-invasive and allows ultraso...
Bonow S, Hernlund E, Eriksson S, Strandberg E, Gelinder Viklund Å.Sweden has a strong tradition of insuring horses for veterinary costs, and orthopedic diagnoses are the most common for insurance claims. The aim of this study was to investigate differences in prevalence and risk of orthopedic diagnoses for Swedish warmblood (SWB) horses classified as jumping (J) or dressage (D) horses. Also, other factors that may influence orthopedic health were investigated, i.e., sex, birth cohort, and participation in young horse tests and competition. The data consisted of 15,619 insured SWB horses born between 2010 and 2020. Horses were classified as J or D horses acco...
Pluim M, Reynolds A, McClure S.High-power laser therapy and extracorporeal shock wave therapy (ESWT) can be safely used to treat tendon and ligament injuries in horses, and the potential beneficial effects have been described. The power of low level lasers is not sufficient for treatment of tendon and ligament injuries in horses. ESWT is used more often to treat tendon and ligament injuries than it is for any other type of condition in horses, but there is limited supporting scientific evidence. Further research should focus on establishing dosage and treatment protocols for both laser therapy and ESWT in horses with clinic...

It provides an overview of current trends and future dire...
Tay A, McMaster M.Equine tendon lacerations are not uncommon secondary to traumatic wounds and degloving lacerations. These wounds are often contaminated and, therefore, basic principles of wound assessment and management are critical to identify the extent of an injury. Ancillary tools to aid physical examination include radiography, ultrasonography, and synoviocentesis (eg, if involving a joint and/or tendon sheath). Prolonged convalescence period, continued external coaptation, and controlled exercise are mainstays of treatment following tenorrhaphy. A poor prognosis for return to full athletic function is e...
Barandalla M, Colleoni S, Perota A, Galli C, Lazzari G.The introduction of ovum pick-up, Intracytoplasmic Sperm Injection (ICSI) and in vitro embryo production in equine reproduction offers significant advantages, including overcoming infertility, high blastocyst yields, embryo cryopreservation, and preimplantation genetic testing (PGT) by collecting few cells extruded spontaneously during embryo growth using a mouth pipette. PGT enables embryo selection before transfer and is particularly useful in breeds with a preference for specific offspring genders, coat color, and detecting genetic diseases. Here, we present the first large-scale validation...

Methods: Seven racehorses that had a clinical history consistent with the presence of a humeral stress fracture were examined using humeral ultrasono...
Baptiste KE, Kyvsgaard NC, Ahmed MO, Damborg P, Dowling PM.Rifampin is an enigma among antimicrobials. Blood and tissue compartment concentrations are a "moving target" along the treatment course due to the complex pharmacodynamic interactions within the body. Rifampin concomitant therapies are for the prevention and treatment of Rhodococcus equi infection in foals, for nearly 40 years. The necessity of rifampin concomitant therapies is based on beliefs that both antimicrobials (e.g., rifampin plus macrolide) penetrate into pulmonary abscesses and intracellular compartments above R. equi minimum inhibitory concentrations (MICs), as well as better ef...
Sanigavatee K, Wonghanchao T, Poochipakorn C, Pongnarudech P, Suchairat T, Jitsopin S, Wanichayanon B, Sripiboon S, Chanda M.Long-distance road transport is known to be stressful for horses, with most research conducted in temperate climates. This study investigated horses' stress responses during long-distance transport before and after a jumping competition in a tropical environment. Ten healthy horses (aged 7.9 ± 1.9 years) were studied. Blood cortisol concentrations, haematology, and heart rate variability (HRV) were monitored during outbound (OTJ) and inbound journeys (INJ). Cortisol concentrations increased five minutes after unloading and remained elevated for up to 180 minutes in the OTJ (P < 0.05-0.001)...
Tually P, Currie G.The horse racing industry, like any sport, must contend with the effects of injuries on an athlete's performance and longevity. Catastrophic fractures linked to preexisting bone fatigue can be prevented with the use of imaging technology, such as the nuclear medicine bone scan. The accessibility and affordability of imaging for racehorses remain obstacles. The conventional role of bone scintigraphy has evolved with the advent of advanced techniques, including MRI, CT, and PET. Concurrently, SPECT has expanded the role of scintigraphy in the racehorse. This article explores the conventional and...

The mare exhibited acute limb swelling, fever, cutaneous ulceration, lymphatic dysfunction and unknown anemia. Comprehensive diagnostics, including bacterial culture, whole-genome sequencing, anti-elastin antibody (AEAb) ELISA, and diagnostic imaging, confirmed the pathogens causing cellulitis and secondary lymphangitis. AEAb levels were elevated, correlating with lymphatic degradation, while radiography...
Meistro F, Ralletti MV, Rinnovati R, Spadari A.Subtle locomotor asymmetries are common in horses and may go unnoticed during routine pre-race clinical inspections, particularly when based solely on subjective evaluation. This study aimed to describe vertical head and pelvic movement asymmetries in racehorses that passed official pre-race inspections at a traditional racing event. Twenty-four horses were analysed using a markerless AI-based gait analysis system while trotting in-hand and during lungeing in both directions. Asymmetry parameters (HDmin, HDmax, PDmin, and PDmax) were extracted from video recordings, with values ≥0.5 consider...
Kiełbik P, Witkowska-Piłaszewicz O.Iron is unquestionably an essential element of physical performance for horses, just as it is for many other animals, including humans. Although post-exercise equine iron deficiency is not a common problem, recent studies showed that equine athletes may be considered a model for human exercise physiology. Sports anemia among human athletes is a common nutritional issue and remains one reason for poor physical fitness. Thus, this study area needs comprehensive knowledge since iron homeostasis changes in equine athletes remain unrecognized. The current review aims to summarize studies describing...
Mellish M, Burns J, Elce Y, Stull JW.Donkeys (Equus asinus) in East Africa are recognised as working with poorly designed harnesses and carts.
