The relationship between human health and horses encompasses various aspects of interaction, including therapeutic, occupational, and zoonotic elements. Equine-assisted therapy is utilized in some therapeutic settings to support mental and physical health in humans, leveraging the horse's role in facilitating emotional and physical rehabilitation. Occupational health considerations arise for individuals working with horses, addressing potential risks such as injuries and allergic reactions. Additionally, zoonotic diseases, which can be transmitted between horses and humans, are an area of concern for public health, necessitating research into prevention and control measures. This page compiles peer-reviewed research studies and scholarly articles that explore the multifaceted connections between human health and horses, focusing on therapeutic applications, occupational health, and zoonotic disease dynamics.
Radvila P.The effect of heterologous and homologous antitoxin is the same if an equal amount of antitoxin is present in the organism. In man there are no circulating antibodies in the blood after the first injection of the toxoid because there is no natural immunity against the tetanus antigen. After the second injection, man develops the same immunity as animals. Large antitoxin doses protect people for a longer period than small doses. Normally 3,000 I. U. of the heterologous antitoxin protects people for 2 to 3 weeks. In man and sheep 2 ml of the adsorbed vaccine produces an earlier and longer-lastin...
Dordel HJ.Since November 1973 a riding course has been carried out with six blind adults. Due to the instructional methods the participants were able to ride independently, without an attendant, after only 30 hours. The effects of riding on the blind encompass coordination training and development of muscle strength. Furthermore, riding has a pronounced influence on the circulatory system. This attractive reaction activity provides the person who, as a result of his specific handicapping condition is limited in both the spatial and social fields, with an expansion of his living space and sphere of exper...
Montgomery PC, Bello AC, Rockey JH.N-terminal tetrapeptides from heavy chains of equine γGab- and γT-globulins, and of human γG and γA myeloma proteins and a γM macroglobulin, have been studied. The equine and human heavy chains lacked free α-amino-terminal groups. After mild alkaline hydrolysis, glutamic acid was identified as the terminal amino acid by reaction with dimethylaminonaphthalenesulfonyl chloride, tentatively identifying pyrrolid-2-one-5-carboxylic acid (PCA) as the unreactive terminal residue of each heavy chain. Peptides lacking a free α-amino group were isolated from subtilisin and pronase digests of the ...
Richter GW, Moppert GA, Lee JC.1. Fingerprints of tryptic digests of apoferritins from a human liver, horse spleens and ACI rat livers were made by means of electrophoresis and chromatography on microcrystalline cellulose, and were compared.
2. All tryptic peptides also present in apoferritins from the human liver and the horse spleens were also present in apoferritin from the rat livers.
3. In the digests of horse and of rat apoferritin there was a peptide that was not present in the digests of human apoferritin. Another peptide was obtained from human and from rat apoferritin, but not from horse apoferritin.
4. T...
Simon SR, Cantor CR.The UV circular-dichroism spectra of human and horse hemoglobins have been determined at various degrees of partial saturation with oxygen. Spectra of the two native hemoglobins were compared with spectra of the corresponding proteins modified with a reagent known to eliminate the conformational rearrangement normally associated with cooperativity. Such comparison indicates that one region, around 260 mmu, is sensitive chiefly to the state of the hemes; changes in another region, around 285 mmu, may be correlated with the conformational transformation linked to cooperative interactions. All ci...
Steinhardt J, Hiremath CB.Many of the stability characteristics of horse ferrihemo-globin (Hb+) in acid solutions, such as pH dependence and susceptibility to stabilization by iron ligands, are shared by human ferrihemoglobin, but striking differences between the two proteins exist. The most noticeable is the much greater rate of denaturation of the human protein at all pH values. Other differences include a shift to higher pH in the equi-librium between native and acid-denatured forms, differ-ences in the temperature at which the temperature effect on the equilibrium-pH curve reverses, a complete absence in human Hb+ ...
Guan F, Uboh CE, Soma LR, Luo Y, Jahr JS, Driessen B.Oxyglobin (OXY) and Hemopure (HMP) are produced from bovine hemoglobin (Hb) and were developed for the treatment of anemia in animal and human patients, respectively. Hemolink (HML) is a blood substitute of human Hb origin under development. The ability of these agents to carry oxygen in circulating blood and their promise to improve oxygen delivery to tissues supports the potential for their abuse in equine and human athletes. To deter athletes from abuse of these agents, a method has been developed for the detection, confirmation and quantification of OXY, HMP, and HML in equine and human pl...
Xu X, Murphy LA.The presence of insecticides like pyrethrins and synthetic pyrethroids, combined with the synergist piperonyl butoxide, in animal feeds can pose a risk to both animal and human health by contaminating the food chain. In this study, a simple and fast method was developed for the simultaneous determination of these compounds in contaminated animal feeds using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Sample preparation was carried out using a QuEChERS-based approach, and the method was validated with acceptable accuracy ranging from 84 to 115% and precision below 10%. The limit ...
Scott EA, Sandler GA.Electromagnetic blood flowmeters and flow probes are used to measure blood flow in blood vessels throughout the circulatory system. The principle of this measuring device is based on laws of electromagnetic induction discovered in the 19th century. The instrument has been predominantly used in research, but is presently used in human cardiovascular units to measure blood flow in blood vessels, and in prosthesis in conjection with cardiovascular surgical procedures. Electromagnetic flow equipment provides the most accurate measurement (in vivo) of blood flow available, both for acute and chroni...
Bakst M, Hadick S, Proudman J, Maruyama K.This study was conducted to determine the crossreactivity of antisera to human prolactin (PRL), adrenocorticotropic hormone (ACTH), and growth hormone (GH) to turkey pituicytes. In addition, crossreactivities of the above antisera and antiserum to turkey GH to pituicytes of turkey, cat, rabbit, horse, owl monkey, and human were evaluated. Results of the immunocytochemical localizations showed that with one exception antisera to human hormones were positive for each species tested. Turkey pituicytes failed to crossreact with antiserum to human GH. Likewise, antiserum to turkey GH failed to cros...
Schlichtherle C.This paper describes the importance of fumonisins for human beings and animals and shows data for the occurence in food. Corn-based food samples (n = 299) purchased in the area of munich were analyzed for fumonisin content using an enzyme immunoassay.Fumonisins are mycotoxins produced byFusarium species, especially byFusarium moniliforme andFusarium proliferatum. Occurrence of fumonisins in corn and in cornbased foods and feeds has been reported from almost all over the world. In several animal species different diseases are traced back to fumonisin toxicosis. Fumonisin levels of 5-10 ppm inho...
Riley CB, Padalino B, Rogers CW, Thompson KR.There is an increased understanding of shared human-animal risk in terms of "one welfare", whereby when animals are at risk, so are people, so preventing injury to one species may also prevent injury to the other. Because transport-related injuries to horses are common, the authors considered this paradigm to study road equine transport-related injuries to humans in New Zealand. The aim was to determine their frequency and associated factors by distributing a survey to horse industry participants through industry organisations asking about their horse activities, road transport experiences, an...
Gosai F, Gosai N.Strangles is a contagious upper respiratory tract infection primarily affecting equines. It is rare disease with zoonotic transmission. It is caused by the bacterium, . We present the rare case of strangles in an elderly patient complicated by bacteraemia, osteomyelitis and native valve endocarditis. The patient was treated successfully with appropriate antibiotics and no surgical intervention was needed. In an age of accelerated emerging zoonosis, this is an important entity clinicians should be aware of to prevent delay in diagnosis and poor outcome. Conclusions: Strangles is a disease of eq...
Ionatamishvili NI, Tsverava DM, Loriia MSh, Avaliani LA.One hundred children with cerebral palsy, aged 3-14 years, were divided into two equal groups, the first one including 50 children assigned to ride therapy and the second one--to Bobath therapeutic gymnastics. All the patients underwent a functional examination, which was rated using score system worked out by the authors, thus enabling a quantitative evaluation of treatment efficacy. In all the cases, physical rehabilitation resulted in a positive but not the same effect, with ride therapy being significantly (p < 0.001) more beneficial treatment compared to therapeutic gymnastics. Ride thera...
Tyler CR, Filby AL, Bickley LK, Cumming RI, Gibson R, Labadie P, Katsu Y, Liney KE, Shears JA, Silva-Castro V, Urushitani H, Lange A, Winter MJ....Many factors have been considered in evaluations of the risk-benefit balance of hormone replacement therapy (HRT), used for treating menopausal symptoms in women, but not its potential risks for the environment We investigated the possible environmental health implications of conjugated equine estrogens (CEEs), the most common components of HRT, including their discharge into the environment, their uptake, potency, and ability to induce biological effects in wildlife. Influents and effluents from four U.K. sewage treatment works (STWs), and bile of effluent-exposed fish, were screened for six ...
Calatroni A, Avenoso A, Ferlazzo AM, Lindner A, Campo GM.Plasma glycosaminoglycans (GAGs) were isolated and purified by chromatographic procedures in healthy humans and horses before and after physical exercise. A weak anion exchange resin was used to separate polyanions. Humans exercised on a cycloergometer, while horses were exercised on a treadmill and in show jumping competition. Some GAGs were isolated from untreated plasma and operationally defined as native proteoglycans (PGs), while the total GAG amount was isolated from mild alkali treated plasma. Plasma GAG concentrations in terms of galactosamine and galactose, the respective components o...
Mayr A.Prophylactic immunization of animals against obligat and nonobligat pathogenic zoonoses benefit human health in many ways both directly and indirectly. Typical examples of a direct protective effect are the vaccinations of dogs, cats and foxes against rabies as well as the vaccinations against respiratory diseases in cows, horses, dogs and cats to which the most varied species of pathogens of noncompulsory zoonoses contribute. A considerable contribution to the protection of human health is made by the vaccination against salmonellosis and leptospirosis, against vesicular stomatitis, American ...
Newton TA, Rose SR.Phenylbutazone is a potent nonsteroidal, anti-inflammatory drug often used by veterinarians to treat racetrack animals. Its use in human beings is limited because of significant adverse effects and the availability of newer, safer drugs. We report the case of a 24-year-old man who ingested 17 g of equine phenylbutazone over a 24-hour period to treat the pain of a toothache. He developed grand mal seizures, coma, hypotension, respiratory and renal failure, and hepatic injury. Serum phenylbutazone concentration obtained approximately eight hours after presentation was 900 micrograms/mL. The pati...
Glathe H, Strittmatter HU, Kunze M, Sinnecker H.The influence of acidic pH on the infectivity and neuraminidase activity of human, equine and avian type A influenza virus strains has been studied. Following exposure to pH 3 human and equine strains lost their infectivity completely, whereas all investigated strains of the subtypes Hav6N2 and Hav7Neq2 retained a certain amount of infectivity. In contrast to human and equine strains the avian strains retained also 38% of their original neuraminidase activity after acidic treatment. Partial retention of infectivity and the relative stability of the neuraminidase following exposure to acidic pH...

Ryder S, Bracho D.Antibodies against Venezuelan Equine Encephalitis Virus (VEEV) were studied in the human population of Mara District, Zulia State, Venezuela. Two hundred thirty nine blood samples were taken from the towns of San Rafael de Mara, Santa Cruz de Mara, La Sierrita-4 Bocas, Carrasquero, Isla de San Carlos e Isla de Toas, during june, july and september, 1988. Donors samples were classified by age, sex and serological titres. Eighty nine were less than 15 years old (37.2%) and 150, over 15 years old (62.7%). From the 239 samples, 224 were negative (93.7%) and 15 positive (6.3%). Our results indicate...
HORI J, AOKI K.Electrophoretic studies were made of normal horse and human serum albumins over the pH range 3.6–6.8 and at 25 °. The ionic strength of acetate or phosphate buffer used was 0.1, and the concentration of protein was 0.5% (g./100 ml.). Patterns were usually enantiographic and there were two (N and F1) or three (N, F1, and F2) boundaries in the pH range 3.6–5.2. The areas of the N and F1 boundaries changed continuously with pH, and the area of F2 was almost constant. The results were interpreted, in the same way as was previously done in the case of bovine serum albumin, by the isomerization...
Zinchenko AV, Govorova YS.Critical to the understanding the mechanism of destruction and protection during cryopreservation of biological objects is the knowledge of the conformational transitions of biopolymers experiencing low temperatures in the presence of cryoprotective agents. This information may be derived from the kinetic and thermodynamic parameters of macromolecular thermal denaturation kinetics under different environmental conditions. Objective: The study deals with the influence of cryoprotective agents (glycerol, 1.2-propanediol (1.2-PD), and dimethyl sulfoxide (DMSO)) on thermodynamic and kinetic parame...

Spengler MI, Rasia M.The aggregation capacity of human erythrocytes lies between that of the non-aggregating bovine erythrocytes and the remarkably aggregating equine ones. As the ability to aggregate is attributed to cell factors and the composition of the plasma proteins, the role that plasma proteins play in the aggregation process in these three species was studied. Washed erythrocytes were suspended in phosphate-buffered saline (PBS; pH 7.4, 300 mOsm/L) plus polyvinylpyrrolidone (PVP) in a suitable concentration to obtain an average intensity of aggregation (control media). The superimposed effect of replacin...
Young C, Horton J.Animals have been used for medicinal and therapeutic purposes throughout much of the course of human history., Formal research into the use of animals for therapeutic purposes being in the 1960s, where work investigating the use of pet psychotherapy for treatment of behavior disorder in children was published. More recently, animals have been incorporated into a number of “animal-assisted interventions”, including animal-assisted activities, animal assisted-therapy, and service animal programs. The most common forms of animal-assisted interventions for the treatment of mental health condit...
Kuroda T, Minamijima Y, Niwa H, Mita H, Tamura N, Fukuda K, Toutain PL, Ohta M.Fosfomycin (FOM) is an approved veterinary medicinal product for large animals in Japan, but Clinical breakpoint (CBP) for antimicrobial susceptibility test (AST) is not defined for animals. This study aimed at conducting a pharmacokinetics/pharmacodynamics (PK/PD) analysis to determine the PK/PD cutoff for the CBP in horses. Drug concentrations following single intravenous administration (IV) of 20 mg/kg body weight (BW) FOM in nine horses were measured using liquid chromatography/mass spectrometry. The data were modelled using a nonlinear mixed-effects model, followed by Monte Carlo simulati...
Ebeling-Koning NE, Fowler JT, DelBianco JD, Surmaitis RM.Veterinary medication exposure may result in human toxicity, with approximately 6,000 exposures to veterinary-only medications reported to poison centers in 2022. There is a paucity of literature on the management of poisoned patients secondary to pharmaceuticals intended for equine use. Pergolide is a dopamine and serotonin receptor agonist and is currently approved to treat equine Cushing's disease. It was previously approved in the United States (US) to treat Parkinson's disease in humans; however, it was withdrawn from the market in 2007 due to its association with valvular heart disease....
McGill S, Coleman R, Hayes M.Indoor arenas do not always include mechanical ventilation or stirring fans and occupancy by horses and humans can be sporadic and inconsistent, which creates a challenging space for understanding and predicting variations in temperature, moisture, and airflow. To understand the interior environment within indoor arenas, monitoring was conducted at 15 facilities within 200 kilometres of Lexington, KY. Environmental monitoring of dry bulb temperature, relative humidity, dew point temperature, air speeds, and solar radiation took place over 7 days in the winter and summer to examine temporal var...
Hudson S, Blackburn J, Fish M, Ousey K.Police officers wear personal protective equipment (PPE) to reduce their risk of injury while on duty. Despite the unique policing activity of riding a horse, little is known about the PPE used by mounted officers. The aim of this research was to assess the use, comfort, and functionality of mounted police PPE. Twenty officers from three UK Mounted Sections were recruited. Semi-structured interviews and range of movement assessments were conducted. Interview data was analysed using reflexive thematic analysis. Three main themes were generated: and Much of the PPE worn by mounted officers is ...

Giovannetti-Singh G.In 1644, the Manchus, a Tungusic population from northeast Asia, conquered Ming China, establishing the Qing Empire. Four years later, Crimean Tartar horsemen joined a major uprising against the Polish-Lithuanian Commonwealth, gravely destabilizing one of Europe's largest states. These near-simultaneous incursions by ostensibly nomadic, horse-riding 'Tartars' into firearm-defended sedentary states generated extensive historiographical reflection on the role of nomads and their warhorse-centred armies in shaping human history. This article explores how the Jesuit Martino Martini drew on these T...
Tulloch JSP, Schofield I, Jackson R, Whiting M.The veterinary industry has some of the highest rates of non-fatal work-related injuries, yet safety culture remains unexplored. Utilising a survey distributed to all UK employees of a consolidated group of veterinary practices, this study aimed to describe the prevalence of work-related injuries in equine, production animal, and mixed veterinary practices, and to understand the behaviours of injured persons. There were 144 respondents. Over 90 % of clinicians experienced injury during their careers, versus a third of non-clinical staff. Injuries to equine veterinarians were predominately ki...
Swezey E, Szydziak E, Angus LDG, Mehta V, Cardozo-Stolberg S.Equestrian trauma is recognized as a high-risk injury mechanism with the potential for significant morbidity and mortality. Although horse-related injuries are more frequently seen in a rural environment, they can also occur in urban settings. Urban physicians should be mindful of these potential cases. Methods: A retrospective review was performed on all patients treated at Nassau University Medical Center, East Meadow, New York, for equestrian-related trauma from January 1, 2000, to December 31, 2024. Results: Twenty-nine equestrian trauma patients ages 10-70 were included, with injuries ob...
Loy J, Sornalingam K, Cawley A, Scrivener C, Keledjian J, Noble GK.Altrenogest is a synthetic progestogen widely used in equine reproductive management. Adverse effects to altrenogest have been reported in people with cutaneous exposure reported as the highest exposure pathway. Despite these reports, there has been no quantitative research to determine the capacity for altrenogest to be absorbed through skin. This study aimed to determine if cutaneous application of oral altrenogest results in systemic absorption in mares and to evaluate the influence of application site. A randomized, two-period, two-treatment crossover study was undertaken in eight mares. M...
Wesołowska M, Szczuka E. In animals, staphylococci constitute a significant part of the normal skin microbiota and mucous membranes. There is limited information available on staphylococci isolated from healthy horses. These skin-associated bacteria can be easily transferred between animals and horse riders via direct contact. Patients undergoing hippotherapy (i.e., medical or therapeutic sessions with horses) are especially at risk of being colonized by horse skin-associated bacteria. However, it remains unclear whether equine skin is colonized by antimicrobial-resistant (AMR) opportunistic pathogens, which may be o...
McDonald C, Cullen S, O'Connor S, Warrington G, Pugh J, McGoldrick A, Nolan C, Losty C.The thoroughbred horse breeding industry contributes significantly to the Irish economy. However, staff shortages threaten the economic sustainability of the industry, as well as the welfare of both horses and workers. Previous research on the staffing crisis faced by the broader horseracing industry has highlighted mental health concerns as a factor. Furthermore, the influence of workplace context on mental health has been widely recognised in organisational psychology. The aim of this study was to assess prevalence rates of Common Mental Disorders (CMDs) in Irish thoroughbred horse breeding ...
