Equine protozoal myeloencephalitis is a progressive neurologic disease of horses most commonly caused by infection with the apicomplexan parasite Sarcocystis neurona. Factors affecting neuroinvasion and neurovirulence have not been determined. We investigated the pathogenesis of infection with S. neurona in horses with severe combined immune deficiency (SCID). Two immunocompetent (IC) Arabian h...

BACKGROUND Lyme disease can affect people, dogs, and horses, but it remains poorly understood, especially in the horse. Determining the seroprevalence of Borrelia burgdorferi in horses in different geographic areas will enable better understanding of the epidemiology of the disease, thus improving diagnosis and treatment of affected animals. HYPOTHESIS To determine the seroprevalence of B. bu...

OBJECTIVE To compare financial returns between pinhooked yearling horses (ie, bought and trained for approximately 5 months with the goal of selling the horse at "2-year-olds in training" sales) that had mild or severe training failure and horses that had planned versus nonplanned training failure. ANIMALS 40 Thoroughbred pinhooked yearling horses. PROCEDURE During the period from September...

The purpose of this study was to describe clinical, hematological and fecal PCR results from 161 horses involved in outbreaks associated with ECoV. The outbreaks happened at four separate boarding facilities between November 2011 and April 2012 in the States of CA, TX, WI and MA. Following the molecular detection of ECoV in the feces from the initial index cases, the remaining herdmates were cl...

Injuries sustained by horses during racing have been considered as an unavoidable part of horse racing. Many factors may be associated with the musculoskeletal injuries of Thoroughbred race horses. This study surveyed the amounts of nonsteroidal anti-inflammatory agents (NSAIDs) in injured horse's biological system (plasma) at Kentucky racetracks from January 1, 1995 through December 31, 1996. ...

peptic ulcer is a very common disorder in horse race and foals. in the present research possible relationship between gastric ulcer and the prevalence of cardiac arrhythmia were studied in two different horse race. in this respect, 13 caspian miniature horses and 8 arab horses were studied. gastric ulcers and cardiac arrhythmias were diagnosed in 13 horses (62%) and 12 (57%) out of 211 horses, ...

seven caspian miniature horses, aged above two years, were used for this study. the skeleton of these horses were cleaned and prepared using appropriate techniques. the vertebral column was studied and photographed. the vertebral column in one of these horses showed variations in thoracic, lumbar and sacral region. the vertebral formola was c7, t19,l5,s6 and a pair of 19th rib was fused with th...

To investigate the prevalence of Cryptosporidium infection in horses, a total of 221 faecal specimenswere collected from 18 villages of Urmia, northwestern Iran. The samples were studied microscopically bymodified Ziehl-Neelsen staining. The cryptosporidial infection was found in the collected samples from 11 of18 villages. Although the prevalence of the infection was 15.8%, none of the infecte...

The aim of this study was to determine the seroprevalence of Toxoplasma gondii in mares and stallionsin the province of Ankara. Sera from 168 clinically healthy horses were tested for the presence ofToxoplasma gondii antibodies using the Sabin Feldman dye test. Toxoplasma gondii infection wasdetermined in 62 (36.9%) of 168 horses with the titers ranging from 1:16 to 1:256.

Background: Limited information existed on performance tests in Iranian Arab horses. Aims: The objective of this study is to investigate time related changes of cardiac troponin I (cTnI), atrial natriuretic peptide (ANP) and oxidative/antioxidant biomarkers in the serum of Arabian horses before and after regular training. Methods: Blood samples were collected from jugular vein of 25 Arabian hor...
