Disease prevention in horses encompasses strategies and practices aimed at minimizing the occurrence and spread of infectious and non-infectious diseases within equine populations. These practices include vaccination programs, biosecurity measures, and regular health monitoring. Vaccination helps to stimulate the horse's immune system to protect against specific pathogens, while biosecurity measures, such as quarantine and sanitation, reduce the risk of disease transmission. Regular health monitoring, including physical examinations and diagnostic testing, aids in early detection and management of potential health issues. This page compiles peer-reviewed research studies and scholarly articles that explore various methods and their effectiveness in preventing diseases in horses, as well as the development and implementation of prevention programs in different equine settings.

Sinclair IS, McCormick JS, Clark JG.The three heterologous anti-sera currently provided for tetanus prophylaxis have been compared with reference to the production of untoward reactions in 498 patients, and to the blood antitoxin concentrations produced in 76 patients. Equine serum, although giving rise to more reactions, was the only effective agent in terms of the levels and duration of serum antitoxin concentration produced. The local response to a test dose of any of the three sera is not a reliable guide to immediate or late general reactions.
Jurjanz S, Collas C, Quish C, Younge B, Feidt C.Data on soil ingestion in horses are lacking in contrast to other free-range animals. The importance of soil as a vector for environmental pollutants to food is less relevant in horses but several disorders secondary to soil ingestion, such as sand colic or enteritis have been reported. Therefore, soil ingestion has been studied on Irish sport horses grazing at three offered levels of daily herbage: 2, 3 and 4% of their body weight. Soil ingestion was estimated by the faecal recovery of a soil natural marker. Horses had 4.5, 4.1 and 3.7% of soil in their total intake respectively for the 2, 3 ...
Poh KC, Cole ZT, Smarsh DN, Springer HR, Kelly K, Kenny LB, Machtinger ET.To evaluate the safety of repeated applications of permethrin concentrations (0% control, 1.5%, 5%, and 10%) to the necks and faces of horses and assess the efficacy and longevity of permethrin as an equine tick repellent. Methods: 5 healthy adult Quarter Horses. Methods: Each treatment was applied to the neck of each horse (0.01 m2) 4 times a day, for up to 10 days. An 8-mm biopsy was taken to evaluate postexposure dermal responses. Any treatments that were not withdrawn were applied to a quadrant of the horse's face 4 times a day, for up to 5 days. For tick bioassays, a treatment was applied...
Terschuur JA, Coomer RPC, Handel I, Pressanto MC, McKane SA.Skin closure of laparotomy incisions using topical 2-octyl cyanoacrylate (2-OCA) mesh provides a secure bactericidal barrier in humans, which may reduce the risk of postoperative incisional complications. However, the benefits of using this mesh have not been objectively assessed in horses. Methods: From 2009 to 2020, three methods of skin closure were used following laparotomy for acute colic, including metallic staples (MS), suture (ST) and cyanoacrylate mesh (DP). The closure method was not randomised. Owners were contacted 3 months or more after the surgery to record any postop...
Manglai D, Wada R, Kurohmaru M, Sugiura T, Yoshihara T, Oikawa M, Hayashi Y.To clarify the functions of the equine guttural pouch, the distribution of various immunoglobulin isotypes and subisotypes in the guttural pouch mucosa were examined in healthy horses. IgGa was present in the mucosa of guttural pouch, mucosal lymph nodules and submucosal lymph nodules. IgM was scattered in the mucosal lymph nodules and in the germinal centers of the submucosal lymph nodules. IgGc was recognized only in the submucosal lymph nodules. These immunoglobulin isotypes and subisotypes were found in lymphocytes and plasma cells. On the other hand, IgA was detected in glandular epitheli...
Kimpfler S, Pospischil A, Rüsch P, Sydler T.One of the essential tasks of veterinary pathology is the gross and microscopic examination of animals post mortem. Frequently requests are made for the cause of disease or death in the absence of a precise history or an otherwise specific assignment e.g. whether a notifiable disease is involved. The general examination is supplemented by a spectrum of additional examinations depending on the case whereas attempts are made to keep the costs within limits and to answer the client's request with justifiable effort. 36,365 necropsy cases and 9192 organs submitted between 1988 and 2004 were analys...
Ríha J, Minár J, Králík O, Krupa V.The adverse effect of blood-sucking dipterous insects (gadflies, gnats, black flies, midges) was determined and checked, as exerted on the working performance of draft horses working in forests; the possibilities of protecting horses with repellents were studied at the same time. The trial was conducted under field conditions in the territory of the Broumov Forest Establishment in the Náchod and Trutnov districts. A 10% water emulsion of the repellent, diethyltoluamide, was used; the horses were treated with the emulsion in a 24-hour interval. Over the seventy working days from the 1st of Jul...
Wiedenheft AM, Traub-Dargatz JL, Gillette SC, O'Keefe GJ, Rao S, Salman MD.The purpose of this study was to assess the effectiveness of two different methods of online education using the knowledge base of African horse sickness (AHS) among US equine veterinarians as a model. An e-mail was sent to US veterinary members of the American Association of Equine Practitioners (AAEP), inviting them to participate in a complementary online educational opportunity. We determined participants' baseline knowledge of AHS by their responses in an AHS case scenario. Participants were then randomly assigned to either a Webinar module or a text-formatted module, followed by an educa...
Ross C, Haussler KK, Kenney JD, Marks D, Bertone JJ, Henneman K, May KJ.Vigorous and prolonged effort is required to gain true mastery of the healing arts. Conventional and complementary medicine have complementary strengths and weaknesses. Like the yin and yang of traditional Chinese medicine, they naturally flow into one another by a process of induction, creating balance. Integrative medicine is the frontier; it is the future. If we are to progress beyond our current understanding and ability to heal, we must work with theoretic models that allow us and our perception to operate "outside the box." For some, this understanding is intuitive. It is through coopera...
Boudreault A, Boulay G, Marois P, Pavilanis V.Live human and equine influenza virus strains modified by serial passage on allantois-on-shell system (AOS) in the presence of normal horse serum were administered orally or intranasally to volunteers or horses. Mostly mild clinical short-lasting reactions, replication in nasal mucosae, transmission to placebo recipients and significant local or circulating antibody rises were observed following administration to volunteers of strains modified by five or less serial passages on AOS in the presence of normal horse serum (NHS). Milder clinical reactions, no replication, no viral transmission and...
Yasine A, Ashenafi H, Geldhof P, Bekana M, Tola A, Van Brantegem L, Van Soom A, Duchateau L, Goddeeris BM, Govaere J.Trypanosoma equiperdum (T. equiperdum) causes dourine, a venereally transmitted infection in horses. Purification of semen by single layer centrifugation (SLC) has been proven to be successful in reducing venereally transmitted diseases when dealing with other pathogens. The objective of this study was to evaluate the purification of T. equiperdum spiked semen by SLC. Semen was spiked using cryopreserved T. equiperdum stabilates (Dodola strain isolate 943). In total, 6 concentrations, varying from 10 to >5 × 10 trypanosomes, were added to semen samples. Subsequently, SLC was performed ...
Wyant LA.The Internet is a fast-growing technology that allows information (text as well as images) to be shared across the world in an instant. As computer systems, software, and Internet services become less expensive options, the world becomes more experienced and comfortable with these technologies. In the foreseeable future, equine veterinarians are likely to be better educated about diseases and treatments, better connected with specialists for consultations on difficult cases, able to respond to client communications more efficiently, able to accurately educate clients, and able to communicate w...
Smit LA, Wouters IM, Heederik D, Douwes J.Endotoxins are cell-wall components of Gram-negative bacteria that are commonly present in plants and plant products and in faecal matter. This review presents an overview of endotoxin exposure levels, associated health effects, and relevance regarding veterinary practice. Exposure to airborne endotoxin is especially high in the agricultural sector and among veterinarians, and in particular among those working with horses or farm animals. Inhalation of endotoxins may cause acute airway inflammation and respiratory symptoms that can lead to (non-allergic) asthma and chronic obstructive pulmonar...
Yu YY, Xu MS, Liang H, Wang HY, Yu CQ, Liu Q.Despite over 40 years of research on the human immunodeficiency virus type 1 (HIV-1) vaccine, we still lack a considerable progress. Equine infectious anemia virus (EIAV) is a lentivirus in the Retroviridae family, akin to HIV-1 in genome structure and antigenicity. EIA is an important infectious disease in equids, characterized by anemia, persistent infection, and repeated fevers. The EIAV attenuated vaccine in China is the only lentiviral vaccine used on a large scale. Elucidating the mechanism of waning and induction of protective immunity from this attenuated vaccine strain will provide a ...
Thein P, Essich G.An investigation was carried out upon occurrence and course of infectious and non infectious diseases as well as the mortality in foals born and raised at the State Stud Marbach/Lauter between 1982 and 1991. The foals have been investigated from birth to weaning, they consisted of 177 Thoroughbred Arabians and 285 German Warmblood foals (total 462 foals). The diseases were divided into pre-, peri- and postnatal according to their known or assumed cause and onset. There was a preponderance of prenatal diseases (11.25%) whereas the perinatal rate was 1.30% and the postnatal rate of diseases was ...
Wolf TM, Gandolf AR, Dooley JL, Atkinson MW, Wolfe BA.Vaccination has been an important component of preventative health care programs of North American zoologic institutions in their protection of valuable species against West Nile virus (WNV) infection since its detection in 1999. Although approved only for horses, commercial WNV vaccine has been used for the purpose of protection of nondomestic species, including avian, equid, and rhinoceros species. Currently, there are two commercial equine vaccines available, a killed vaccine and a recombinant viral-vectored vaccine. Both products have been used for the vaccination of Greater One-horned rhi...
Puschner B, Galey FD.Poisoning in the horse can present a highly complex case. The practitioner, owner, toxicologist, and pathologist play important roles, and all contribute information that may be important to the case. Once all the information is available, all the evidence is collected (historical, clinical, pathologic, and analytic), and proper sampling of specimens has occurred, a complete summary of the findings can be provided to the client. Based on identification of a potential toxic source and, ultimately, the diagnosis, specific treatment of affected animals and prevention of additional cases can be in...
Singh S, Kumar B, Dilbaghi N, Devi N, Prasad M, Manuja A.Isometamidium chloride (ISM) is a trypanocide for the prophylactic and therapeutic use against vector-borne animal trypanosomosis (mainly Surra caused by ) and African animal trypanosomosis caused by //). ISM was found to be an efficient trypanocide for therapeutic/prophylactic use against trypanosomosis; however, it produces some local and systemic detrimental effects in animals. We synthesized isometamidium chloride-loaded alginate gum acacia nanoformulation (ISM SANPS) to lessen the detrimental side effects of isometamidium chloride (ISM) while treating trypanosomal diseases. We intended to...

Clayton HM, Trawford AF.A field study was designed to investigate the re-establishment of patent lungworm infections in donkeys following an anthelmintic treatment regime which was effective against Dictyocaulus arnfieldi. In April 1979 faecal samples from 259 donkeys were examined and each animal classified as a negative, low positive or high positive excretor of lungworm larvae. During the summer the control group of 126 donkeys showed an increase in the number of excretors from 80 per cent in April to 91 per cent in October. At the same time there was a rise in the faecal larval output of individual animals so tha...
Langner K, Hörügel U, Donat K, Vervuert I.Screening of commercial mineral feeds and mineral licks on the German market containing selenium (Se) in relation to the Se status in equines in Thuringia with different forms of Se supplementation. Methods: Commercially available Se-containing minerals for horses identified by an online research were evaluated for their Se concentration, Se source, flavour carrier and recommended dosage according to the manufacturer's labelling. Furthermore, serum Se status in 8 equine farms was regularly monitored over the period of one year. The sampled horses either received no Se supplement or Se was supp...
Liu X, Liu Q, Feng X, Tang Q, Wang Z, Li S, Feng Z, Zhu J, Guan X.Due to the disadvantages of human and equine rabies immunoglobulin, it is necessary to develop a substitute for HRIG and ERIG, especially for those people living in the developing countries. Because of higher affinity and lower immunogenicity of rabbit's immunoglobulins, anti-rabies immunoglobulins specific to rabies virus were produced in rabbits as a bioreactor, and had been characterized by ELISA, affinity assay, immunofluorescence assay (IFA), immunocytochemistry, rapid fluorescent focus inhibition test (RFFIT). ELISA, affinity assay and IFA showed that rabbit RIG (RRIG) bound specifically...
Hartung J, Klinckmann G, Adrian U.Dust in horse barns is assumed to contribute to pulmonary disease, it is attempted to reduce the airborne dust by soaking or sprinkling the hay before feeding. Both means cause considerable efforts and increase the relative humidity of the air. This is why a commercial dust-binding agent (Revesto pur) was used in a pilot investigation which was carried out during 2 weeks - one week for control and one week using the agent - in a private horse barn where three horses were regularly stable. The airborne dust was measured by a continuously working instrument. Once a day (7.00 a.m.) the number of ...

Methods: Literature review. Methods: All scientific abstracts published in the ACVS proceedings from 2001 to 2010 were reviewed. The level of evidence of each abstract was evaluated and scored (1-4). Publication information was determined after a broad bibliographic search through multiple online databases. Results: The overall publication rate for ACVS abstracts (n=1,395) was 66% and 11% were published before conference presentation. The majority o...
Zeyner A, Hoffmeister C, Einspanier A, Gottschalk J, Lengwenat O, Illies M.Quarter Horses are particularly susceptible to polysaccharide storage myopathy (PSSM). Nutritional therapy and possibly prophylaxis includes fat-supplemented diets whilst starch supply should be kept to a minimum. Objective: To investigate the glycaemic and insulinaemic response of clinically normal Quarter Horses to concentrates high in fat and low in starch. Methods: Twelve Quarter Horses were studied. The precondition for inclusion in the study population was that the horses had not shown clinical signs of myopathy. The Quarter Horses were fed according to a 4 x 4 Latin square design haylag...
Clayton HM, Duncan JL, Gilbert GA.Over a period of several years the use of pyrantel embonate in the control of helminth infections on three equine establishments was monitored by the examination of faecal samples collected immediately before each anthelmintic treatment. With a monthly interval between treatments for three years the faecal egg output of the horses remained at a very low level. One one establishment this was maintained when the treatment interval was extended to one-and-a-half months after treating monthly for two years. If a treatment interval of one-and-a-half months was used continuously for a number of year...
Willink DL, Smeenk LA, van Oyen PW, de Kruif A.Data from the literature and own data for 67 twin pregnancies were used to establish the factors essential to the decision on how to treat twins at different gestational ages. Spontaneous (natural) reduction was compared with manual embryo reduction. Manual embryo reduction is always indicated when a twin is diagnosed before day 16 after ovulation. Thereafter, the type of fixation is the main determinant. Manual embryo reduction is always first choice for bilateral and unilateral non adjacent embryos and must be applied as early as possible. The change of natural reduction up to day 30, is hig...
Klei TR, French DD, Chapman MR, McClure JR, Dennis VA, Taylor HW, Hutchinson GW.The long-term efficacy of an irradiation attenuated larval (L3) vaccine against Strongylus vulgaris was tested in ponies which were reared on pasture. Prior to foaling, mares were divided into two groups. One group of mares and foals received regular (eight weekly) treatment with ivermectin and the second group remained untreated. Half the foals in each pasture group were vaccinated at eight to ten weeks of age. Foals were weaned at three to four months of age and maintained on separate pastures. At eight to ten months of age, ponies were placed in box stalls and half of each treatment group w...

The assessment has been performed following a methodology compos...
Cardenas NC, Sanchez F, Lopes FPN, Machado G.Most animal disease surveillance systems concentrate efforts in blocking transmission pathways and tracing back infected contacts while not considering the risk of transporting animals into areas with elevated disease risk. Here, we use a suite of spatial statistics and social network analysis to characterize animal movement among areas with an estimated distinct risk of disease circulation to ultimately enhance surveillance activities. Our model utilized equine infectious anemia virus (EIAV) outbreaks, between-farm horse movements, and spatial landscape data from 2015 through 2017. We related...
Hertzsch R.Veterinarians play an essential role in the prevention of doping in equine sports, both as attending clinicians as well as official competition veterinarians. This complex task requires comprehensive knowledge concerning the pertinent regulations. These include official laws, such as the animal protection and medicines laws as as well as rules issued by the responsible equine sports authority. Furthermore, veterinarians are required to determine adequate withdrawal times following the legitimate use of medications in sport horses. This may be performed by applying appropriate data published by...
