Statistical approaches for estimating forelimb ground reaction forces in foals during walking and trotting. Equine models are useful in biomechanics research due to their similarity in musculoskeletal tissue to humans, their athletic nature, and rapid skeletal development which permits ontogenetic studies. However, a continuing challenge in musculoskeletal models for large animal biomechanics is measuring the ground reaction force (GRF) during locomotion and therefore few reports of biomechanical measures such as joint torques. Here we evaluate two statistical approaches for estimating forelimb ground reaction forces in foals (n = 3). Longitudinal motion capture, GRF, and subject mass data during ...
The Concentration and Duration of Lipopolysaccharide Stimulation Produce Different Cytokine Responses in an Ex Vivo Whole Blood Model in Horses. Lipopolysaccharide (LPS) is frequently used in equine research to model clinical endotoxemia; however, there is no standardized protocol for inducing cytokine production in equine whole blood. To address this knowledge gap, the goal of this study was to compare the cytokine responses elicited by three different LPS stimulation protocols. Whole blood was collected from six healthy horses (aged 5-30 years; mixed breeds and genders) from the North Carolina State University teaching herd (IACUC #23-412). Sixty milliliters of heparinized blood were aseptically drawn and divided into 15 mL aliquots....

Clinical signs, clinical pathology and outcomes in horses infected naturally with equine encephalosis virus. Equine encephalosis (EE) is caused by an Orbivirus from the family Sedoreoviridae and is thus similar to African horse sickness (AHS) and Bluetongue viruses (BTV). These viruses are transmitted by Culicoides midges. Equine encephalosis can infect horses, donkeys and zebras sub-clinically while only horses develop clinical disease. The vector's distribution is climate-dependent with evidence for circulation in Southern Africa, the Middle East and India. Global warming could facilitate the expansion of this distribution and consequently the potential spread into Europe should not be overlooked. ...
