Zinc silicate mineral-coated scaffold improved in vitro osteogenic differentiation of equine adipose-derived mesenchymal stem cells. In current study we aimed to coat the PLLA scaffold with zinc (Zn) silicate mineral nanoparticles. Then, using equine adipose-derived stem cells (ASCs) we intended to compare the osteogenic induction potency of Zn silicate mineral-coated PLLA scaffold with uncoated PLLA scaffold and tissue culture plastic (TCPS). Adipose tissues were collected from 3 horses, and isolation of ASCs was achieved by enzymatic digestion. PLLA scaffold was successfully prepared using a phase separation method and coated with Zn silicate mineral nanoparticles. The coating efficiency was then characterized by scanning...
Improved reliability of serological tools for the diagnosis of West Nile fever in horses within Europe. West Nile Fever is a zoonotic disease caused by a mosquito-borne flavivirus, WNV. By its clinical sensitivity to the disease, the horse is a useful sentinel of infection. Because of the virus' low-level, short-term viraemia in horses, the primary tools used to diagnose WNV are serological tests. Inter-laboratory proficiency tests (ILPTs) were held in 2010 and 2013 to evaluate WNV serological diagnostic tools suited for the European network of National Reference Laboratories (NRLs) for equine diseases. These ILPTs were designed to evaluate the laboratories' and methods' performances in detectin...
Surface glycan pattern of canine, equine, and ovine bone marrow-derived mesenchymal stem cells. The use of bone marrow-derived mesenchymal stem cells (MSCs) for clinical and experimental studies is increasing, but full characterization of MSCs in veterinary species is hindered by the variability in species-specific cell surface marker expression and antibody cross reactivity. Recent studies demonstrated that the glycans in the glycocalyx of MSCs are promising candidates as cell biomarkers. In the present study, we analyzed the glycocalyx of canine MSCs (cMSCs), ovine MSCs (oMSCs), and equine MSCs (eMSCs) using a cell microarray procedure in which MSCs were spotted on microarray slides an...
Perceptions of Equid Well Being Well-Being in South Dakota. In South Dakota, the status of equid well being is relatively unknown. This study sought to (a) gain understanding about the current perceptions of nonhuman animal well being in South Dakota, with an emphasis on horses and other equids; (b) determine the level of care equids are reportedly receiving and the perceived challenges to equine well being in South Dakota, and (c) determine if people from diverse geographical locations (east or west of the Missouri River) have similar views on the well being of equids in South Dakota. Respondents indicated the current level of equid well being in Sout...
Single nucleotide polymorphisms for DNA typing in the domestic horse. Genetic markers are important resources for individual identification and parentage assessment. Although short tandem repeats (STRs) have been the traditional DNA marker, technological advances have led to single nucleotide polymorphisms (SNPs) becoming an attractive alternative. SNPs can be highly multiplexed and automatically scored, which allows for easier standardization and sharing among laboratories. Equine parentage is currently assessed using STRs. We obtained a publicly available SNP dataset of 729 horses representing 32 diverse breeds. A proposed set of 101 SNPs was analyzed for DNA ...

Objective: To investigate the level of agreement between board-certified veterinary internists when performing neurologic examinations in horses. Methods: Ninety-seven horses admitted to the Veterinary Teaching Hospital at The Ohio State University from December 1997 to June 1998. Methods: A prospective epidemiologic research design was used. Horses enrolled in...
Equine Assisted Interventions (EAIs): Methodological Considerations for Stress Assessment in Horses. Equine assisted interventions (EAIs) are recently facing an increasing popularity, and are characterized by a wide diversity of practices. However, information on the welfare of animals involved in this kind of activity is often lacking. Horses are highly susceptible to work stressors related to physical constraints and/or to the need to control emotions while interacting with humans. Considerations of the emotional state of horses involved in EAIs have multiple valences: for the safety of humans and animals involved, for the quality and efficacy of interventions, as well as for ethical reason...
Low plasma cortisol and fecal cortisol metabolite measures as indicators of compromised welfare in domestic horses (Equus caballus). The hypothalamic-pituitary-adrenal (HPA) axis response to chronic stress is far from straight forward, particularly with regards to animal welfare. There are reports of no effect as well as both decreases and increases in cortisol after chronic stressors. Therefore, the first aim of the present study was to determine how measures of compromised welfare, such as chronic pain and haematological anomalies, related to cortisol levels in domestic horses (Equus caballus). Domestic horses are an informative model to investigate the impact of chronic stress (due to environment, pain, work, housing con...
Combination of optical coherence tomography and near infrared spectroscopy enhances determination of articular cartilage composition and structure. Conventional arthroscopic evaluation of articular cartilage is subjective and poorly reproducible. Therefore, implementation of quantitative diagnostic techniques, such as near infrared spectroscopy (NIRS) and optical coherence tomography (OCT), is essential. Locations (n = 44) with various cartilage conditions were selected from mature equine fetlock joints (n = 5). These locations and their surroundings were measured with NIRS and OCT (n = 530). As a reference, cartilage proteoglycan (PG) and collagen contents, and collagen network organization were determined using quantitative ...
Seroprevalence of Coxiella burnetii among domestic ruminants and horses in Poland. Coxiella burnetii is the causative agent of Q fever. The cases of the disease are recorded in various species, including domestic animals. The aim of this investigation was to estimate the seroprevalence of C. burnetii in ruminants including cattle, sheep, goats, and horses. Totally, 2082 serum samples from 936 goats, 933 cattle, 89 sheep, and 124 horses, including various horse breeds, were tested by ELISA or complement fixation test. The examination revealed that Polish horses are seronegative while in the populations of cattle and small ruminants, seropositive animals are presented. The per...
D-loop haplotype diversity in Brazilian horse breeds. The first horses were brought to Brazil by the colonizers after 1534. Over the centuries, these animals evolved and adapted to local environmental conditions usually unsuitable for exotic breeds, thereby originating locally adapted Brazilian breeds. The present work represents the first description of maternal genetic diversity in these horse breeds based on D-loop sequences. A D-Loop HSV-I fragment of 252 bp, from 141 horses belonging to ten Brazilian breeds / genetic groups (locally adapted and specialized breeds) were analysed. Thirty-five different haplotypes belonging to 18 haplogroups we...
Maximum permissible load for Kiso horses trotting over a short, straight course. This study aimed to determine the load-bearing capacity of trotting Kiso horses using gait analysis. Ten Kiso horses with a height at withers of 128 cm were included. Their riders were fitted with a marker (70 mm in diameter placed on their chest) recorded by two digital DVD cameras while trotting along a short, straight course. In total, eight tests were performed for each horse: the first with a 70 kg load; six with randomly loaded weights ranging 80-130 kg; and then a final test again with a 70 kg load. Three-dimensional movement of the marker was analyzed using a motion capture system...
Molecular analysis of alternative transcripts of equine AXL receptor tyrosine kinase gene. Since athletic performance is a most importance trait in horses, most research focused on physiological and physical studies of horse athletic abilities. In contrast, the molecular analysis as well as the regulatory pathway studies remain insufficient for evaluation and prediction of horse athletic abilities. In our previous study, we identified receptor tyrosine kinase () gene which was expressed as alternative spliced isoforms in skeletal muscle during exercise. In the present study, we validated two alternative splicing transcripts (named as for long form and for short form) in equine s...
Veterinary and Equine Science Students’ Interpretation of Horse Behaviour. Many veterinary and undergraduate equine science students have little previous horse handling experience and a poor understanding of horse behaviour; yet horses are one of the most unsafe animals with which veterinary students must work. It is essential for veterinary and equine students to learn how to interpret horse behaviour in order to understand demeanour and levels of arousal, and to optimise their own safety and the horses' welfare. The study utilised a qualitative research approach to investigate veterinary science and veterinary technology and undergraduate equine science students' i...
Veterinary student competence in equine lameness recognition and assessment: a mixed methods study. The development of perceptual skills is an important aspect of veterinary education. The authors investigated veterinary student competency in lameness evaluation at two stages, before (third year) and during (fourth/fifth year) clinical rotations. Students evaluated horses in videos, where horses were presented during trot on a straight line and in circles. Eye-tracking data were recorded during assessment on the straight line to follow student gaze. On completing the task, students filled in a structured questionnaire. Results showed that the experienced students outperformed inexperienced s...
Changes in the Total Fecal Bacterial Population in Individual Horses Maintained on a Restricted Diet Over 6 Weeks. Twelve mature (aged 5-16 years) horses and ponies of mixed breed and type were fed restricted (1.25% BM Dry matter) quantities of one of two fiber based diets formulated to be iso-caloric. Diet 1 comprised of 0.8% body mass (BM) of chaff based complete feed plus 0.45% BM low energy grass hay (the same hay used for both diets). Diet 2 comprised 0.1% BM of a nutrient balancer plus 1.15% BM grass hay. Fecal samples were collected at week 10 and week 16. DNA was extracted and the V1-V2 regions of 16SrDNA were 454-pyrosequenced to investigate the bacterial microbiome of the horse. The two most abun...
[Equine dentistry: Survey on Swiss horse owners]. The interest in equine dentistry has significantly increased in the last 15 years. On the part of the veterinarians as well as of the horse owners there is a strong attention to the topic. The aim of the questionnaire was to investigate amongst horse owners what their level of information and preferences about dental treatment are and how they are implemented. The questionnaire was translated into the three national languages and included 20 questions about level and sources of information, frequency of treatments and the horse owner's stance over sedation of the animals. With a return rate of...
Complete mitochondrial genomes of Triodontophorus serratus and Triodontophorus nipponicus, and their comparison with Triodontophorus brevicauda.

In the present study, the complete mitochondrial (mt) genome sequences of T. serratus and T. nipponicus have been determined. The mt genomes of T. serratus and T. nipponicus are circular molecules with 13,794 bp and 13,701 bp in size, respectively. These circular mt genomes encode 36 genes, including 12 protein-coding genes, two rRNA genes and 22 tRNA genes. All of these genes are transcribed in the same direction and gene arrangements are consistent with...
Circulating microRNA profiles of Hendra virus infection in horses. Hendra virus (HeV) is an emerging zoonotic pathogen harbored by Australian mainland flying foxes. HeV infection can cause lethal disease in humans and horses, and to date all cases of human HeV disease have resulted from contact with infected horses. Currently, diagnosis of acute HeV infections in horses relies on the productive phase of infection when virus shedding may occur. An assay that identifies infected horses during the preclinical phase of infection would reduce the risk of zoonotic viral transmission during management of HeV outbreaks. Having previously shown that the host microRNA ...

Spectroscopic Study of the Interaction between Horse Heart Myoglobin and Zirconium(IV)-Substituted Polyoxometalates as Artificial Proteases. A recent study [Angew. Chem. Int. Ed. 2015, 54, 7391-7394] has shown that horse heart myoglobin (HHM) is selectively hydrolyzed by a range of zirconium(IV)-substituted polyoxometalates (POMs) under mild conditions. In this study, the molecular interactions between the Zr-POM catalysts and HHM are investigated by using a range of complementary techniques, including circular dichroism (CD), UV/Vis spectroscopy, tryptophan fluorescence spectroscopy, and H and P NMR spectroscopy. A tryptophan fluorescence quenching study reveals that, among all examined Zr-POMs, the most reactive POM, 2:2 Zr -...
Antigenic characterization of 52-55kDa protein isolated from Trypanosoma evansi and its application in detection of equine trypanosomosis. Trypanosoma evansi is a haemo-protozoan parasite responsible for the disease surra, an economically important disease of wide range of domestic and wild animals. The present diagnostic methods using soluble antigens have inherent problems like lack of standardized and reproducible antigens, as well as ethical issues. This entails further efforts for search of defined antigenic molecules with satisfying sensitivity and specificity for sero-epidemiology of trypanosomosis. In present investigation, we have identified and purified 52-55kDa immuno-dominant protein cluster in molecular mass ranges b...
Genomic Dissection of an Icelandic Epidemic of Respiratory Disease in Horses and Associated Zoonotic Cases. Iceland is free of the major infectious diseases of horses. However, in 2010 an epidemic of respiratory disease of unknown cause spread through the country's native horse population of 77,000. Microbiological investigations ruled out known viral agents but identified the opportunistic pathogen subsp. () in diseased animals. We sequenced the genomes of 257 isolates of to differentiate epidemic from endemic strains. We found that although multiple endemic clones of were present, one particular clone, sequence type 209 (ST209), was likely to have been responsible for the epidemic. Concurrent ...
Diagnosis of equine influenza. During the summer months, there will be increased movement and, therefore, increased mixing of the horse population, leading to a higher risk of disease transmission and subsequent clinical cases. It is important that both vets and owners remain vigilant for equine influenza infection. Here, Adam Rash, of the Animal Health Trust, discusses the diagnosis of this disease.
Investigation of the Fim1 putative pilus locus of Streptococcus equi subspecies equi. The Gram-positive bacterium subspecies () is the causative agent of strangles, among the most frequently diagnosed infectious diseases of horses worldwide. Genome analysis of strain 4047 (4047) identified a putative operon, Fim1, with similarity to the pilus loci of other Gram-positive bacteria. The Fim1 locus was present in all strains of and its close relative subspecies () that have been studied to date. In this study we provide evidence that the putative structural pilus proteins, SEQ_0936 and CNE, are produced on the cell surface during growth and infection. Although the proteins ...
