Gildea S, Quinlivan M, Murphy BA, Cullinane A.Previous studies in experimental ponies using interferon gamma (IFN-γ) as a marker for cell mediated immune (CMI) response demonstrated an increase in IFN-γ gene expression following vaccination with an ISCOM subunit, a canarypox recombinant and more recently, an inactivated whole virus vaccine. The objective of this study was to carry out an independent comparison of both humoral antibody and CMI responses elicited following vaccination with all these vaccine presentation systems. Antibody response of 44 Thoroughbred weanlings was monitored for three weeks following the second dose of prima...
Emara EM, Imam H, Hassan MA, Elnaby SH.Analysis of trace elements in mammalian hair has the potential to reveal retrospective information about an individual's nutritional status and exposure. As trace elements are incorporated into the hair during the growth process, longitudinal segments of the hair may reflect the body burden during growth. Using LIBS technique, Na, K, Ca, Mg, Si, Fe, Pb and Zn were detected in a single strand of horse hair. The results obtained through LIBS technique on hair samples were compared with the traditional technique (AAS) on digested acidified solution of the same samples. The effects of the experime...
Salim B, Bakheit MA, Sugimoto C.Equine trypanosomosis (ET) is a protozoan disease affecting equines in many parts of the world. We examined 509 samples collected from geographically distinct regions in eastern, central and western Sudan to estimate the endemicity of ET using the generic ITS1-PCR diagnostic methods. Results revealed that horses and donkeys were infected by Trypanosoma brucei subgroup, Trypanosoma vivax, Trypanosoma simiae and Trypanosoma congolense. The prevalence of Trypanosoma spp. was higher in horses (12.7%, n=393) than in donkeys (3.4%, n=116). The highest prevalence was observed in South Darfur State (1...

Wylie CE, Collins SN, Verheyen KL, Newton JR.Laminitis is a highly debilitating disease of the foot known to have a complex and multifactorial aetiology of metabolic, inflammatory, traumatic or vascular origin. The disease has major welfare implications due to unrelenting pain associated with degenerative changes, which often necessitate euthanasia on welfare grounds. Despite this, there have been few high-quality studies investigating risk factors for equine laminitis, and only a limited number of risk factors have been previously investigated. The aim of this study was to conduct a case-control study of risk factors for active episodes...
Canisso IF, Pinn TL, Gerdin JA, Ollivett TL, Buckles EL, Schweizer CM, Ainsworth DM.A 5-year-old Quarter horse broodmare was evaluated for inappetence, depression, and diarrhea 13 days after aborting a 9-month gestation fetus. Clinical and laboratory examination ruled out uterine rupture and peritonitis. Ultrasonography of the uterus combined with cytological analysis of peritoneal fluid suggested the existence of diffuse lymphoma. A multicentric B-cell lymphoma involving the uterus and ovary was confirmed at necropsy and histopathological examination. Lymhome multicentrique à cellules B comme cause possible d’avortement chez une jument poulinière Quarter Horse. Une jumen...

Schroeder OE, Aceto HW, Boyle AG.The objective of this study was to examine all kick injuries to the radius and tibia seen in an ambulatory setting over an 11-year period in order to determine factors affecting outcome. Medical records of 51 horses seen for a kick injury to the radius or tibia were reviewed. Signalment, physical examination findings, type of management, and outcome were evaluated. There was a significant association between the presence of bony crepitus and a lameness score of ≥ 4/5 and a poor outcome. There was no relationship between signalment and outcome, but significantly more Thoroughbred/Thoroughbred...
Holmquist JG, Schmidt-Gengenbach J, Haultain SA.Grazing management necessarily emphasizes the most spatially extensive vegetation assemblages, but landscapes are mosaics, often with more mesic vegetation types embedded within a matrix of drier vegetation. Our primary objective was to contrast effects of equine grazing on both subalpine vegetation structure and associated arthropods in a drier reed grass (Calamagrostis muiriana) dominated habitat versus a wetter, more productive sedge habitat (Carex utriculata). A second objective was to compare reed grass and sedge as habitats for fauna, irrespective of grazing. All work was done in Sequoia...
Kailaanmäki A, Kinnunen T, Kwok WW, Rytkönen-Nissinen M, Randell J, Virtanen T.The responses of allergen-specific CD4(+) T cells of allergic and healthy individuals are still incompletely understood. Our objective was to investigate the functional and phenotypic properties of CD4(+) T cells of horse-allergic and healthy subjects specific to the immunodominant epitope region of the major horse allergen Equ c 1. Specific T-cell lines (TCLs) and clones were generated from peripheral blood mononuclear cells with Equ c 1(143-160), the peptide containing the immunodominant epitope region of Equ c 1.

Wise LN, Kappmeyer LS, Mealey RH, Knowles DP.Equine piroplasmosis is caused by one of 2 erythrocytic parasites Babesia caballi or Theileria equi. Although the genus of the latter remains controversial, the most recent designation, Theileria, is utilized in this review. Shared pathogenesis includes tick-borne transmission and erythrolysis leading to anemia as the primary clinical outcome. Although both parasites are able to persist indefinitely in their equid hosts, thus far, only B. caballi transmits across tick generations. Pathogenesis further diverges after transmission to equids in that B. caballi immediately infects erythrocytes, wh...
McIlnay TR, Miller SM, Dugan SJ.Obstruction of the nasolacrimal outflow pathway in horses is not uncommon. Causes of obstruction include foreign bodies, trauma, and congenital abnormalities. Placement of a nasolacrimal retention stylette may prove challenging.

A hand access device (Omniport) was placed followed by 4 laparoscopic porta...
Tozaki T, Swinburne J, Hirota K, Hasegawa T, Ishida N, Tobe T.Genetic maps are extremely important tools for tracing the genes that govern economically significant traits, and microsatellites are a significant component of these. In this study, we isolated 2346 novel horse microsatellites as resources for the construction of high-density horse genetic maps. Of these 2346 markers, 339 (14.5%) horse sequences showed sequence homology to DNA sequences in the human genome, demonstrating that microsatellites as type II markers are valuable resources for developing linkage maps and that they have a potential equal to that of type I markers for developing compa...
Stick JA.In three horses with abdominally retained testicles, teratomas with cyst formation were found. Bone development in the head of the epididymis, near the vascular supply of the tumor, was a consistent finding. Aspiration of the cystic portion of the tumor was necessary for surgical removal in two cases. Although germinal carcinoma cells have been suggested as the cause of teratomas, evidence of malignancy was not seen in any of the three tumors.
Tee SY, Feary DJ.A 9-year-old Miniature Horse gelding infested with ticks (Ixodes holocyclus) was presented with flaccid motor paralysis causing recumbency. Neurological examination and other diagnostic tests did not identify an alternative aetiology, leading to a presumptive diagnosis of tick paralysis. The gelding was treated with tick antiserum and intensive supportive care. He made a gradual recovery over the 48 h following presentation and was discharged without further complications. This case report describes in detail the clinical signs and successful treatment of a Miniature Horse with flaccid paral...
O'Driscoll JG, Troy PT, Geoghegan FJ.The clinical pattern, bacteriological investigation and subsequent treatment of a serious outbreak of venereal disease in stud farms on both sides of the Irish Sea is described. The consistency with which Bacillus proteus was isolated from infected mares and stallions was remarkable. Prompt treatment with ampicillin, to which the organism was sensitive in vitro, eradicated the disease. No local treatment was applied.
Ganjali M, Keighobadi M.Myiasis is the infection caused by a variety of dipterous (fly) larvae in vertebrate's tissue (man and domestic or wild animals). Species of Gasterophilus are obligate parasite of horses, donkeys, zebras, elephants and rhinoceroses. There are records worldwide, but mostly, in tropical and subtropical regions. This case report describes a type of gastric myiasis caused by G. intestinalis in an old lion in a zoo in Sistan, southeast Iran. Myiasis in lions is rarely reported and this is the first report of gastric myiasis in lion.
Gumber S, Baia P, Wakamatsu N.A 15-year-old female gray Appaloosa horse was presented with history of a mass over the right dorsal commissure of vulva for the past 7 months. Based on histopathological examination, and positive staining with factor VIII-related antigen, vimentin, and Verhoeff-van Gieson stain, the vulvar mass was diagnosed as hemangiosarcoma with marked solar elastosis.
White NA.Intestinal infarction associated with cranial mesenteric artery thrombosis, without strangulation obstruction of the intestine, was studied in 18 horses. Findings normally of value in evaluating horses with acute abdominal pain (heart rate, rectal palpation findings, gastric reflux) or classification of the degree of pain were not helpful in diagnosing the problem. Similarly, packed cell volume, plasma total protein, circulating white blood cell count, peritoneal white blood cell count, and peritoneal fluid total protein were not of value in predicting severity of the intestinal damage, locati...
Murray RC, Branch MV, Dyson SJ, Parkin TD, Goodship AE.Adaptation of osteochondral tissues is based on the strains experienced during exercise at each location within the joint. Different exercise intensities and types may induce particular site-specific strains, influencing osteochondral adaptation and potentially predisposing to injury. Our hypotheses were that patterns of equine distal tarsal subchondral bone (SCB) thickness relate to the type and intensity of exercise, and that high-intensity exercise leads to site-specific increases in thickness. SCB thickness was measured at defined dorsal and plantar locations on magnetic resonance images o...
Berreta A, Kopper J.Probiotics are live microorganisms that when consumed in adequate amounts confer a health benefit to the host. The objective of this review is to critically evaluate the definition of probiotics with reference to their use as supplements in horses, research regarding quality control, and propose areas for future focus. Several studies, performed over a 19-year period, have consistently identified deficiencies when comparing actual contents to label claims. Furthermore, basic information such as expiration dates and storage instructions are often missing from the labels. Finally, the authors wi...
Brounts SH, Rashmir-Raven AM, Black SS.This case report describes a distinctive deep cutaneous lesion in a 1-year-old Quarter Horse filly with hyperelastosis cutis. The horse had a typical clinical presentation of hyperelastic skin associated with a 6-month history of cutaneous wounds that developed following minor cutaneous trauma. Punch biopsies of skin from the affected horse were thinner than similar biopsies from an age- and breed-matched control. Significant microscopic lesions were not seen in cutaneous punch biopsies stained with haematoxylin and eosin and Masson's trichrome stains, but the ultrastructure of the dermis from...
May CE, Guthrie AJ, Keys B, Joone C, Monyai M, Schulman ML.The response to the first outbreak of contagious equine metritis in South Africa included pioneering a web-based platform to coordinate key aspects of a national, real-time polymerase chain reaction (qPCR)-based stallion screening programme to determine the distribution and prevalence of Taylorella equigenitalis in stallions and exposed mares. Objective: To define the hypothesised pre-existing status of T. equigenitalis in the South African equine population and progression of the epidemiological investigation via the implementation of a molecular diagnostic-based surveillance programme. Metho...
Payne RC, Sukanto IP, Graydon R, Saroso H, Jusuf SH.During an outbreak of trypanosomiasis in cattle, buffalo and horses on the island of Madura, a survey was conducted to determine the prevalence of Trypanosoma evansi in the region. Blood samples were collected from 130 cattle and 147 buffalo in 5 villages, whole blood was examined for trypanosomes by the microhaematocrit (MHCT) method and serum samples were subjected to an enzyme linked immuno absorbent assay to detect T. evansi antibodies. T. evansi was detected by MHCT in 50% of the buffalo examined and 13% of the cattle, while antibodies were detected in 47% of the buffalo and 30% of the ca...
Moyer W.Hoof wall defects in horses are common occurrences, and, fortunately, many of those detected present little or no danger to the individual horse. Those defects that are either presently a problem or have a great likelihood of being a problem do often require specialized consideration. Horse shoeing and farriery are ancient practices; over the years, a multitude of methods, theories, and management schemes have been proposed. It is unfortunate to note that few studies are available to provide an accurate incidence rate, a better understanding of the various causes, and, lastly, a comparative ap...
Bowen JM, Tobin N, Simpson RB, Ley WB, Ansari MM.Six stallions were subjected to extensive cleansing of the penis and prepuce with water, Ivory Soap and water, or Betadine surgical scrub and water. The stallions were all washed for 14 days, and then allowed 14 days respite. This pattern of washing and resting was repeated consecutively. Swabs were taken from all 7 stallions twice weekly and semen was collected once a week for bacteriological examination. All forms of cleansing altered the bacterial flora of the stallion's penis; the Ivory Soap tended to encourage the replacement of the normal flora with coliform organisms, while Betadine fav...
Sutie JW.Animals normally ingest small amounts of fluorides in their diet with no adverse effect. An increased ingestion of fluoride can be harmful to animals, and grazing animals can be damaged by the consumption of high-fluoride vegetation. Cattle have been the species most commonly affected, and the symptoms of excessive fluoride ingestion in that species include; lesions in the developing dentition, skeletal lesions, lameness, chemical evidence of tissue fluoride ingestion in that species include: lesions in the developing take and decrease in production. The level of fluoride which can be tolerate...
Böse R, Peymann B.From Babesia caballi in vitro cultures a preparation of 100% infected erythrocytes was obtained. From this, B. caballi antigens were extracted with the detergent 3-[(3-Cholamidopropyl)-dimethylammonio]-1-propane-sulfonate (CHAPS) and used as ELISA antigens. A control antigen of normal erythrocytes from the same donor horse was prepared in an identical manner. The ELISA and Western blot were validated by testing of sera from horses experimentally infected with B. caballi or B. equi or not infected with Babesia spp. ELISA and Western blot results were compared with those obtained by the immunofl...
Robert C, Valette JP, Denoix JM.The relationship between the presence of radiological abnormalities and subsequent racing performance is controversial. However, as training is expensive and time consuming, it would save time and money to identify subjects with osteo-articular lesions not compatible with a normal racing career on the basis of routine radiographic screenings at yearling age. Objective: To evaluate the impact of osteo-articular lesions on racing ability in French Trotters and identify radiographic changes associated with failure in 'qualification', in order to provide objective criteria for selection of horses ...
de Wasseige S, Picotte K, Lavoie JP.A study reported low systemic availability of injectable dexamethasone nebulized to healthy horses using the Flexineb mask. When used in horses with severe asthma and a different nebulizer, lack of efficacy and cortisol suppression were observed. Objective: Nebulized dexamethasone is as effective as PO administration for the treatment of severe asthma in horses. Methods: Twelve horses with severe asthma from a research herd. Methods: Randomized clinical trial. Horses were divided into 2 groups and received 5 mg of dexamethasone sodium phosphate by nebulization using a Flexineb mask (NE, n = 6)...
Malik P, Singha H, Goyal SK, Khurana SK, Kumar R, Virmani N, Shanmugasundaram K, Pandey SB, Kant R, Singh BK, Singh RK.Equine infectious anemia (EIA) is a retroviral infection of horses. Horses infected by EIA virus (EIAV) become inapparent carriers that remain asymptomatic for the remainder of their life span and serve as infection source to other horses. In this study, agar gel immunodiffusion test and ELISA were used to investigate the presence of antibodies to EIAV in equines. A total of 67,042 equine serum samples from 19 states and two union territories were tested during April 1999 to September 2012. The results revealed that none of the animals were positive for antibodies to EIAV from 1999 to December...
Pöschke A, Krähling B, Failing K, Staszyk C.The equine periodontal ligament (PDL) is a fibrous connective tissue that covers the intra-alveolar parts of the tooth and anchors it to the alveolar bone-it, therefore, provides a similar function to a tendinous structure. While several studies have considered the formation and structure of tendons, there is insufficient information particularly on the molecular composition of the PDL. Especially for the equine PDL, there is limited knowledge concerning the expression of genes commonly regarded as typical for tendon tissue. In this study, the gene expression of, e.g., (, and fibrocartilage m...
