Equine health encompasses the study and management of diseases, disorders, and overall well-being of horses. It involves understanding various physiological systems, preventive care, and treatment strategies to maintain optimal health in equine populations. Common areas of focus include nutrition, infectious diseases, orthopedic conditions, and reproductive health. Research in equine health aims to advance knowledge on diagnostic methods, therapeutic interventions, and management practices that improve horse welfare and performance. This page collects peer-reviewed research studies and scholarly articles that explore the diverse aspects of equine health, offering insights into current findings and advancements in the field.
Boone CW, Harell GS, Bond HE.Large-scale separation of mixtures of mammalian cells was obtained with the A-1X zonal centrifuge rotor and density gradients consisting of Ficoll dissolved in modified Eagle's MEM suspension-culture medium. The cells remained viable as tested by plating efficiency or by motility observed with time-lapse photography. Rabbit thymocyte and HeLa cell mixtures were separated with 99 and 89 per cent purity, respectively. Mixtures of thymocytes and suspension-cultured, human acute leukemia cells (Roswell Park strain LKID) were separated with 93 and 91% purity, respectively. HeLa cells were isolated ...
Oishi S.The author has already reported on the time course of blood level of sulfonamides in horses at various dose schedules3). The present paper is concerned with the tissue distri-bution of sulfadimethoxine and sulfamonomethoxine in horses. The distribution of sulfonamides has been reported by KoNDol) in experimental animals, in which the concentrations of these drugs in the kidney, liver, lung and spleen were found to be close to the blood level. Many investigators ascribed the low concen-tration of sulfonamides in the spinal fluid to the existence of a blood-brain barrier, and also observed that ...
Henry RW, Diesem CD, Hunter MA, Rankin JS.Eleven ponies were used to perfect a surgical approach to the brachial plexus that would offer maximal exposure to the plexus, with minimal trauma. One pony was euthanatized to determine whether surgical exposure to the plexus was feasible. By approaching the plexus from the prescapular region, the only muscle that was found necessary to incise was the cutaneus omobrachialis. The rest of the procedure required only blunt dissection. In the other 10 ponies, the wounds healed by first intention, and the gait was not affected by the surgery.
Williamson CC, Herr S.The distribution of positive dourine cases found on the complement fixation test at the Veterinary Research Institute, Onderstepoort from 1981 to 1984, is recorded. Within the Republic of South Africa, foci of infection occurred in the Johannesburg, Pretoria, Potchefstroom, Rustenburg, Upington, Lichtenburg, Kroonstad, Louis Trichardt, Middelburg (Cape) and Mossel Bay state veterinary districts. In Bophuthatswana, Transkei, Lesotho, South West Africa and Swaziland, positive cases were also recorded. Anti-complementary activity of horse sera does not present a problem. In donkey and mule sera, ...
Kent RJ, Lacer LD, Meisch MV.Migratory birds could introduce West Nile (WN) virus to Arkansas. The purpose of this study was to establish a cooperative arbovirus surveillance program to monitor mosquitoes and birds in Arkansas for arboviruses. Our objectives were to: 1) perform routine, multicounty collections of mosquitoes and test them for eastern equine encephalitis, St. Louis encephalitis, and WN viruses; and 2) conduct passive surveillance by testing dead wild birds for WN virus. Arbovirus surveillance was organized by the Arkansas Department of Health, University of Arkansas, and Vector Disease Control Incorporated....
Xu J, Cai J, Suresh M, Peek SF, Darien BJ.Equine PSGL-1 (ePSGL-1) is widely expressed on equine PBMC as a homodimer with sialylation (sLeX) modifications that contribute to P-selectin binding affinity. To investigate the role of other potential post-translational modifications required for high-affinity P-selectin binding, ePSGL-1 was transfected into CHO cells expressing equine FucT-VII and/or C2GnT. P-selectin-IgG chimera binding by ePSGL-1 transfected into CHO cells only occurred when both FucT-VII and C2GnT were expressed, establishing that fucosylation and core-2 branching are required as post-translational modifications for high...
Gürelli G, Canbulat S, Aldayarov N.Species composition and distribution of intestinal ciliates were investigated in the feces from 15 domestic horses living in Bishkek, Kyrgyzstan. Twenty-three species belonging to 14 genera were identified. This is the first study on intestinal ciliates in domestic horses living in Kyrgyzstan. The mean number of ciliates was 14.1 ± 6.8 x10(4) cells ml(-1) of feces and the mean number of ciliate species per host was 6.0 ± 3.2. No endemic or new species were detected. Blepharocorys was the major genus as these ciliates were detected in high proportions. In contrast Holophryoides, Allantosoma w...
Hohenhaus MU, Bostedt H.108 mares with a total of 135 oestrous cycles were examined. 30% of the mares showed development of double follicles, found by palpation and ultrasonography. Eight cases of double ovulation, four of them synchronous and four asynchronous, were examined closely. These cases of double ovulation showed different growth and different development of the follicular wall. This occurred at the same time in cases of synchronous double ovulation whereas it differed in case of asynchronous double ovulation. The later ovulating follicle was still growing while the first one had already burst. With both fo...
Nts'aoana ME, Molapo S, Kompi P, Phalatsi M.Parasitic infection is one of the major problems in equines which negatively influence their health. It hinders working performance of equines. This study was conducted to evaluate donkey owners' knowledge and control measures on prevalence of gastrointestinal parasites (GIPs) in three agro-ecological zones (AEZs) of Maseru district. A total of 144 donkey owners were selected for individual interviews through a stratified random sampling. Descriptive statistics and chi-square tests were used to analyze data. The significance (p <0.05) of different AEZs was tested using a post-hoc cell-wise ad...

Hammons V, Ribeiro L, Munyard K, Sadeghi R, Miller D, Antczak D, Brooks SA.Chestnut coat color in horses is determined by a missense mutation within the MC1R gene. However, the intensity of the chestnut color can vary widely within individuals possessing this genotype. Here, we investigated this variation using standardized photographs of 96 horses. Each horse was ranked lightest to darkest within the cohort for phenotype by 3 blinded observers. A genome-wide association study utilizing the relative shade ranking as the phenotype and using 268 487 single-nucleotide polymorphisms (SNPs) genotyped using the Affymetrix Equine 670k array identified a single significantly...
Harman RM, Churchill KA, Jager MC, Van de Walle GR.Equid herpesvirus 1 (EHV-1) outbreaks occur when virus spreads from infected horses to in-contact horses, primarily via nasal shedding. This study evaluated the efficacy of factors secreted by equine peripheral blood derived mesenchymal stromal cells (PB-MSCs), collectively named the secretome, to inhibit the growth of EHV-1 in (i) 2D epithelial cell cultures (RK-13) in vitro, (ii) 3D equine nasal explants in vitro and (iii) an EHV-1 infection mouse model in vivo. The PB-MSC secretome was found to inhibit EHV-1 in RK-13 cells as well as in the epithelium of equine nasal explants. Although the ...
Verberne LR, Mirck MH.A comparative study of the literature of the past ten years showed that vaccination of horses and ponies against influenza is best done using adjuvant-containing vaccines. Comparable results may probably be obtained by twice inoculating an aquenous vaccine. There are no drawbacks to the use of aluminium-hydroxide as an adjuvant when mineral oil is used as an adjuvant, the first and second vaccinations do not present any problems.

Fontaine M, Fontaine M.In the first part of this paper the conditions for a specific titration of antibodies against the neuraminidase (N) of each of the two horse virus subtypes are defined. The antigens used are: the H72Neq 1 recombining agent to measure the anti Neq1 antibodies and the A/Duck/Ukraine/63 strain for the anti Neq2 antibodies. The immunity response to neuraminidase appears after the natural disease; this response is studied in two foci, one due to a virus belonging to the A equi I subtype (Loire 73 strain), the other to a virus of the A equi 2 subtype (SHN 73 strain). The kinetics of apparition of an...
