Development and use of a polarized equine upper respiratory tract mucosal explant system to study the early phase of pathogenesis of a European strain of equine arteritis virus. The upper respiratory tract mucosa represents the first line of defense, which has to be overcome by pathogens before invading the host. Considering the economic and ethical aspects involved in using experimental animals for pathogenesis studies, respiratory mucosal explants, in which the tissue's three-dimensional architecture is preserved, may be ideal alternatives. Different respiratory mucosal explant cultures have been developed. However, none of them could be inoculated with pathogens solely at the epithelium side. In the present study, equine nasal and nasopharyngeal explants were embed...
Effect of acute exercise on monocarboxylate transporters 1 and 4 in untrained and trained Thoroughbreds.

Repertoire of Theileria equi immunodominant antigens bound by equine antibody. Theileriosis in horses and cattle is caused by tick-borne Apicomplexa parasites and results in death or life-long infection in their respective hosts. Transmission risk associated with persistent infection severely limits movement of horses and cattle resulting in economic losses. The recent reemergence of Theileria equi infection in U.S. horses demonstrates the continual threat Apicomplexa parasites represent to global animal health. A paucity of data concerning equine immune responses to T. equi, including antigens recognized by antibodies in clinically asymptomatic, persistently infected ho...

Prevalence of abnormal radiographic findings in 2-year-old Thoroughbreds at in-training sales and associations with racing performance. To estimate the prevalence of radiographic abnormalities (lesions) in Thoroughbred racehorses at 2-year-old in-training sales and determine whether these lesions and 1-furlong presale workout times were associated with subsequent racing performance. Methods: Retrospective cohort study. Methods: 953 Thoroughbreds. Methods: Repository radiographs of carpal, metacarpophalangeal and metatarsophalangeal (fetlock), stifle, and tarsal (hock) joints were examined. Horses with lesions were classified by lesion type and location. Race performance variables were compared between horses with and without l...
The effects of equine peripheral blood stem cells on cutaneous wound healing: a clinical evaluation in four horses. Stem-cell therapy represents a promising strategy for the treatment of challenging pathologies, such as large, infected wounds that are unresponsive to conventional therapies. The present study describes the clinical application of peripheral blood stem cells (PBSCs) for the treatment of four adult Warmblood horses with naturally occurring wounds, which were unresponsive to conventional therapies for at least 3 months. A visual assessment was performed, and a number of wound-healing parameters (granulation tissue, crust formation and scar formation) were evaluated. In all cases, tissue overgro...
Babesia equi-induced anemia in a Quarter Horse and subsequent regulatory response. A 7-year-old Quarter Horse gelding used for unsanctioned racing was examined because of fever and anorexia. Results: Physical examination revealed fever, tachycardia, and tachypnea. Results of a CBC indicated anemia and mild thrombocytopenia. Results of microscopic examination of a blood smear indicated piroplasms in erythrocytes, consistent with Babesia spp. Regulatory authorities were contacted, and results of serologic testing at the National Veterinary Services Laboratories confirmed acute Babesia equi infection. Results: Equids on the home premises of the index horse were placed under qua...
Pain along the gall bladder meridian in 100 horses. This case series describes clinical findings in 100 horses displaying pain patterns resembling the anatomical course of the gall bladder meridian. The palpatory pain (tenderness) was detected in individual points, as well as along entire sections of the meridian. A few tender points and areas were also diagnosed outside of the meridian. These data are clinically relevant in terms of the diagnosis and classification of musculoskeletal pain in horses. Therapeutic trials will be reported in a subsequent study.

Acute encephalopathy with concurrent respiratory and metabolic disturbances in first known parenteral human administration of flunixin meglumine and acepromazine maleate. Flunexin is a nonsteroidal anti-inflammatory drug approved for veterinary use in horses and cattle. Acepromazine is a phenothiazine derivative used in horses, dogs, and cats. Human exposure to these substances is rare. Methods: We report a case of a human injection of two equine medications, flunixin and acepromazine, which resulted in altered mental status, respiratory alkalosis, gastrointestinal bleeding, and elevation of liver transaminases in a 43-year-old woman who worked as a horse trainer. The patient intentionally self-injected these medications and subsequently presented to the Emerge...
Imaging diagnosis-aortic aneurysm and ureteral obstruction secondary to umbilical artery abscessation in a 5-week-old foal. A 5-week-old foal was evaluated for fever and hematuria of 3 days duration. Cystoscopy localized the blood to be originating from the left ureter. Abdominal ultrasonography revealed left hydronephrosis, hydroureter, and omphaloarteritis of the left umbilical artery with abscess formation that communicated with an arterial structure. Computed tomography (CT) revealed a large aortic aneurysm within the center of the abscess. An exploratory celiotomy was performed and the infection was nonresectable. The prognosis for life was grave; therefore the colt was euthanized. Necropsy findings confirmed ...
Field caesarean section in seven miniature horses and ponies (2009-2012). While in cattle emergency and elective Caesarean sec-tions are commonly performed in the field, either with the animal recumbent or standing (Newman 2008), in the horse there are very few reports of field Caesarean sections (Gillespie 1962; Graff 1963; Leibrecht and Watt 1964; Cohen 1975), and all required general anaesthesia. It is therefore considered a procedure to be performed in a hospital setting. Furthermore, while the second stage of labour lasts as long as 6 h, it lasts only 20 min in horse, which, together with the fact that mares usually need to be transported to the hospital, makes...
Oral L-arginine supplementation impacts several reproductive parameters during the postpartum period in mares. L-arginine is an amino acid which can alter pituitary function and increase blood flow to the reproductive tract. The objective was to determine the effect of supplementing 100g of L-arginine on plasma arginine concentrations, follicular dynamics and ovarian and uterine artery blood flow during the estrus that occurs subsequent to foaling. In Experiment 1, mares were fed 100g L-arginine for 1 day during the last 3 weeks of pregnancy and plasma samples taken for every hour for the first 4h and every other hour until 12h.L-arginine supplementation elevated plasma arginine concentrations from 1 t...
Computed tomographic arthrography of the intercarpal ligaments of the equine carpus. Injuries of the intercarpal ligaments are an important cause of lameness in performance horses. The purpose of this prospective cadaver study was to determine whether computed tomography (CT) arthrography would be a feasible method for visualizing and characterizing intercarpal ligaments in the horse. One cadaver limb from each of eight nonlame horses was collected immediately after euthanasia. For each limb, overlapping 2.0 mm CT images were acquired before and after injection of iodinated contrast medium into the antebrachiocarpal joint, middle carpal joint, and carpal sheath. Spin echo magn...
Development and validation of an equine nerve block simulator to supplement practical skills training in undergraduate veterinary students. Lameness is the most common presenting complaint in equine practice. Performing diagnostic nerve blocks is an integral part of any lameness work-up, and is therefore an essential skill for equine practitioners. However, the opportunities for veterinary students to practice this skill are limited. The aim of this study was to design and validate an equine nerve block simulator. It was hypothesised that the simulator would improve students' ability and enhance their confidence in performing nerve blocks. A simulator was built using an equine forelimb skeleton and building foam. Wire wool targets...
Veterinary students’ attitudes on One Health: implications for curriculum development at veterinary colleges. One Health knowledge has been identified by the North American Veterinary Medical Education Consortium (NAVMEC) as a core competency for all graduating veterinarians. Many veterinary colleges, however, are still in the preliminary stages of exploring how best to incorporate One Health principles into their existing curricula. In February 2012, we conducted a survey among second to fourth-year Professional Veterinary Medicine (PVM) students at the Colorado State University College of Veterinary Medicine and Biomedical Sciences to assess One Health needs and attitudes. Out of 407 students, 93 (2...
