BACKGROUND The prevalence and nature of arrhythmias in horses following general anaesthesia and surgery is poorly documented. It has been proposed that horses undergoing emergency surgery for gastrointestinal disorders may be at particular risk of developing arrhythmias. Our primary objective was to determine the prevalence and nature of arrhythmias in horses following anaesthesia in a clinical...

(Abstract) Recent studies have provided conflicting results in regards to equine intradermal skin testing and its use in defining causative antigens in IgE mediated diseases such as equine recurrent airway obstruction (RAO). This study was divided into two experiments. In the first experiment of this study, the hypothesis tested was normal horses would have minimal variability in the wheals for...

equine piroplasmosis is a severe disease of horses caused by the intra-erythrocyte protozoan, theileria equi and babesia caballi. the aim of this study was to identify equine piroplasmosis based on molecular and morphometrical features in horses in suburb of urmia, west azerbaijan province, iran. from april to september 2011, a total number of 240 blood samples were collected randomly from hors...

The objective of this study was to determine if competition intensity would have an effect on antioxidant status in horses before and during a three-day event. Body weight, body condition score, and blood was sampled from CCI2* (n = 19) and CCI3* (n = 23) horses before the start of dressage, 20 to 30 min following cross-country, and 18-24 h after cross-county. Data were analyzed using a PROC MI...

BACKGROUND Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis occurs in horses with systemic inflammatory response syndrome (SIRS). Peripheral resistance to glucocorticoids has not been investigated in horses. OBJECTIVE To determine if glucocorticoid receptor (GR) function in horses can be measured using flow cytometry, and to use this information to evaluate HPA axis dynamics. ...

To evaluate the bispectral index (BIS) as an indicator of anesthetic depth in Thoroughbred horses, BIS values were measured at multiple stages of sevoflurane anesthesia in five horses anesthetized with guaifenesin and thiopental following premedication with xylazine. There was no significant difference between the BIS values recorded at end-tidal sevoflurane concentrations of 2.8% (median 60 ra...

BACKGROUND This study was performed to determine the prevalence of ulcers in the gastric squamous and glandular mucosa in Polish pleasure horses. STUDY DESIGN Medical records from gastroscopic examinations of 108 pleasure horses of different breeds were reviewed. The study population consisted of two groups; group I (n = 48) with horses that expressed mild clinical signs of gastric ulcer synd...

• In a second study, prevalence of tapeworm infection in 157 horses was randomly evaluated at necropsy during a 12-month period. Anoplocephala perfoliata was identified in 27% of the horses, exceeding what fecal testing would indicate in many herds. Horses <2 years of age, perhaps due to immunologic susceptibility, were at greater risk of tapeworm infection than adult horses. The geometric mean...

Serum specimens from 12 sick and 20 normal horses were examined for levels of different classes of immunoglobulin (Ig) by a single radial immunodiffusion. The level of IgA in the sera of sick horses was about 50% lower than in the sera of normal horses. By contrast, the level of serum IgG was higher in sick than in normal horses. Phytohemagglutinin (PHA) responsiveness of blood lymphocytes show...

Rose Bengal Plate test (RBPT) and Serum Agglutination test (SAT) were used to monitor the seroprevalence of brucellosis in horses in and around Faisalabad, Pakistan. Sera were screened by RBPT and positive or doubtful sera were further processed by SAT for confirmation. The overall seroprevalence of brucellosis in horses was 20.7 and 17.7% by RBPT and SAT, respectively. Source wise seroprevalen...
