The topic of Public Health and horses encompasses the study of interactions between equine populations and human health systems. It involves examining the transmission of zoonotic diseases, which are diseases that can be transferred between animals and humans, as well as the role of horses in the epidemiology of such diseases. This field also considers the impact of equine-related activities on public health, including injuries and environmental effects. Research in this area often explores preventive measures, management strategies, and policies to mitigate health risks associated with horses. This page compiles peer-reviewed research studies and scholarly articles that investigate the intersection of equine and public health, focusing on disease transmission, risk assessment, and health management strategies.
Bourée P.Hydatidosis is a widespread zoonosis infecting a large number of animals and humans. Echinococcus granulosus has the smallest taenia adult of the cestodes but with the largest larva. Its morphologic and biologic features were identified with DNA analysis. Different strains were separated according to the intermediate hosts: sheep, cattle, pigs, horses, camels. Definitive host are canids, mostly dogs, where the worm grows to adulthood in several months. The eggs are scattered in the pasture by wind and water and are ingested by various hosts. The larvae migrate through the intestinal wall and p...
Fukunaga Y, Kumanomido T, Kamada M.Getah virus is a member of the genus Alphavirus in the family Togaviridae and has been frequently isolated from mosquitoes. Seroepizootiologic studies indicate that the virus is mosquito-borne and widespread, ranging from Eurasia to southeast and far eastern Asia, the Pacific islands, and Australasia. The natural host animal of the virus was not known until the first recognized occurrence of Getah virus infection among racehorses in two training centers in Japan in 1978. Outbreaks of clinical disease due to Getah virus infection occur infrequently, and only one outbreak has been reported outsi...
Dávila AM, Silva RA.Animal trypanosome species of economical importance in South America include T. vivax and T. evansi. Both species are described in Brazil, Bolivia, Colombia, French Guyana, Peru, Suriname, and Venezuela. In Argentina and Guyana, only T. evansi and T. vivax are found, respectively. Our studies on T. vivax indicated that the parasite was spreading around 1.3 km per day in Bolivia. We found severe leukopenia in bovines from Pantanal (Brazil) and the Department of Santa Cruz (Bolivia). Because it can cause immunosuppression, the importance of trypanosomiasis control in ensuring success of vaccinat...
Powell DG.Examples of equine disease surveillance at the local, regional, national and international level are discussed in this article. Reporting systems at each level are also considered, and the increasing importance of laboratory confirmed diagnoses is emphasized. The need to develop national disease reporting systems is addressed, particularly with respect to conforming to international trading standards.
Mead DG, Ramberg FB, Maré CJ.In previous experiments we have demonstrated that colonized and wild black flies are competent laboratory vectors of different Mexican and Western USA isolates of vesicular stomatitis virus, serotype New Jersey (VSV-NJ). We have recently demonstrated biological VSV-NJ transmission by black flies using animal models. In the study described here, we tested the vector competence of colonized and wild black flies for the vesicular stomatitis virus, serotype Indiana (VSV-IN). A 1998 equine isolate was used. After a 10 day incubation period, saliva from experimentally infected Simulium vittatum and ...
Ryan MP, McAuliffe O, Ross RP, Hill C.Lacticin 3147 is a broad-spectrum, two-component, lanthionine-containing bacteriocin produced by Lactococcus lactis DPC3147 which has widespread food and biomedical applications as a natural antimicrobial. Other two-component lantibiotics described to date include cytolysin and staphylococcin C55. Interestingly, cytolysin, produced by Enterococcus faecalis, has an associated haemolytic activity. The objective of this study was to compare the biological activity of lacticin 3147 with cytolysin. The lacticin 3147-encoding determinants were heterologously expressed in Ent. faecalis FA2-2, a plasm...
Ketai LH, Temes RT, Deis JL, Allen NL, Wernly JA.To compare rodeo associated large animal injuries to large animal associated trauma from other aetiologies in order to determine whether mandatory protective head-gear during rodeo is warranted. Retrospective analysis related to injury involving large animal admissions between 1 January 1990 and 31 December 1995. The setting is at the University of New Mexico Health Science Center, a level 1 trauma centre. All patients admitted with Injury Severity Scores of 1 or higher following large animal associated injuries. There were 140 admissions for which mechanism of injury was known. Thirty-nine oc...
Krebs JW, Rupprecht CE, Childs JE.During 1999, 49 states, the District of Columbia, and Puerto Rico reported 7,067 cases of rabies in nonhuman animals to the Centers for Disease Control and Prevention, a decrease of 11.2% from 7,961 cases in nonhuman animals and 1 case in a human being reported in 1998. More than 91% (6,466 cases) were in wild animals, whereas 8.5% (601 cases) were in domestic species (compared with 92.4% in wild animals and 7.6% in domestic species in 1998). No cases of rabies were reported in human beings in 1999. Decreases were evident in all major species groups, with the exception of cattle, sheep/goats, ...
Omer MK, Skjerve E, Holstad G, Woldehiwet Z, Macmillan AP.Samples from 2427 cattle, 661 goats, 104 sheep, 98 camels and 82 horses were screened for brucella infections by the Rose Bengal Test and positive reactors confirmed by the complement fixation test. In cattle, the highest individual seroprevalence was in dairy herds kept under the intensive husbandry system, with an individual prevalence of 8.2% and unit (herd) seroprevalence of 35.9%. This was followed by the pastoral husbandry system in the Western Lowlands with 5.0% individual but a higher unit (vaccination site) prevalence of 46.1%. The lowest was in the mixed crop-livestock system in the ...
Yasuda R, Kawano J, Onda H, Takagi M, Shimizu A, Anzai T.To determine patterns of methicillin-resistant staphylococci isolated from apparently healthy horses. Methods: 44 horses from 8 riding clubs in Japan. Methods: Methicill in-resistant staphylococci were isolated from the skin or nares, using a selective medium containing a beta-(symboric) lactam antibiotic, ceftizoxime. Clonality of isolates was determined by use of pulsed-field gel electrophoresis. Detection of mecA, mecl, and mecR1 genes was accomplished by use of polymerase chain reactions. Results: Of the 44 horses, 13 (29.5%) yielded 15 isolates of methicillin-resistant staphylococci. The ...
Boireau P, Vallée I, Roman T, Perret C, Mingyuan L, Gamble HR, Gajadhar A.After the initial report in 1976 of a trichinellosis epidemic caused by the consumption of infected horsemeat, 12 other outbreaks have been described in Europe. Since the first serious human outbreak several experiments have confirmed the susceptibility of horses to Trichinella species and the rapid disappearance of specific antibodies in this host that prevents the use of serological methods for routine screening. A review of the distribution of parasite burdens in muscles of naturally or experimentally infected horses indicates that the tongue is the most likely sample to contain detectable ...
Newton JR, Verheyen K, Talbot NC, Timoney JF, Wood JL, Lakhani KH, Chanter N.Previous use of repeated nasopharyngeal swabbing and culture of Streptococcus equi showed that healthy carriers developed in more than 50% of 'strangles' outbreaks. The guttural pouches were the only detectable site of S. equi colonisation on endoscopic examination of horses during one of these outbreaks and S. equi was sometimes not detected by culture of nasopharyngeal swabs from carriers for up to 2 or 3 months before nasal shedding resumed sporadically. A more sensitive way of detecting S. equi on swabs from established guttural pouch carriers was therefore required. Conveniently selected ...
Ceci L, Carelli G.This paper reviews basic information on the knowledge of tick-borne diseases, babesiosis, anaplasmosis and theileriosis, in horses, cattle, sheep and goats in Italy with particular reference to the southern part of the country. It is stressed that there is limited knowledge about the parasite species present, their vectors, distribution, prevalence and impact on livestock production and there is the need to assess their epidemiology. A study carried out in the Apulia region to assess the prevalence of Anaplasma marginale infection in 1,648 cattle showed a seroprevalence of 17% using the Card A...
Kosuge J, Goto Y, Shinjo T, Anzai T, Takatori K.Sixty-six new and used samples of horse bedding materials: 60 rice straws, 2 wheat straws, 2 timothy hays and 2 wood chips, were collected from horse breeding stables of 33 farms in Japan and examined for the presence of Emericella nidulans (E. nidulans; anam. Aspergillus nidulans). The incidence of E. nidulans in the bedding materials was 75.8% and there was no significant difference in detection of the fungus between the new and used materials (25 out of the 33 samples, respectively). The growth of E. nidulans isolated in sterilized rice straw culture was accelerated by the addition of water...
Barclay AJ, Paton DJ.Hendra has been recognized in Australia as a new zoonotic disease of horses since 1994/5 and subsequent work has shown that the viral agent is endemic in certain species of fruit bat. The Hendra virus is the type species of a new genus within the sub-family Paramyxovirinae, which also contains another newly identified zoonotic bat virus, namely Nipah. It is assumed that contact with bats has led to the Hendra virus being transferred to horses on each of the three separate incidents that have been reported in the last five years. No evidence has been found for widespread subclinical infection o...
Saville WJ, Reed SM, Morley PS, Granstrom DE, Kohn CW, Hinchcliff KW, Wittum TE.To investigate risk factors for development of equine protozoal myeloencephalitis (EPM) in horses. Methods: Case-control study. Methods: 251 horses admitted to The Ohio State University Veterinary Teaching Hospital from 1992 to 1995. Methods: On the basis of clinical signs of neurologic disease and detection of antibody to Sarcocystis neurona or S neurona DNA in cerebrospinal fluid, a diagnosis of EPM was made for 251 horses. Two contemporaneous series of control horses were selected from horses admitted to the hospital. One control series (n = 225) consisted of horses with diseases of the neu...
Baldini M, Stacchini P, C뫝a F, Miniero R, Parodi P, Facelli P.The cadmium content of muscle, liver, kidney and blood samples from 62 horses slaughtered in Italy was investigated. Cadmium was determined by graphite furnace atomic absorption spectrometry (GFAAS) after wet digestion of the samples. The mean and median contents of all samples were (on a fresh weight basis) 75 and 41 micrograms kg-1 for muscle, 2.46 and 2.10 mg kg-1 for liver, 20.0 and 13.5 mg kg-1 for kidney. The cadmium level in blood samples was always below 6 micrograms l-1. The cadmium concentrations in muscle, liver and kidney were found to be related to the life span of the specimens a...
Wang LF, Yu M, Hansson E, Pritchard LI, Shiell B, Michalski WP, Eaton BT.An outbreak of acute respiratory disease in Hendra, a suburb of Brisbane, Australia, in September 1994 resulted in the deaths of 14 racing horses and a horse trainer. The causative agent was a new member of the family Paramyxoviridae. The virus was originally called Equine morbillivirus but was renamed Hendra virus (HeV) when molecular characterization highlighted differences between it and members of the genus Morbillivirus. Less than 5 years later, the closely related Nipah virus (NiV) emerged in Malaysia, spread rapidly through the pig population, and caused the deaths of over 100 people. W...
Vos JH, Deleu SA, Heling W, de Vries AR, Zeeuwen AA.The most relevant results of a written questionnaire among veterinarians in the Netherlands are presented and discussed. The inquiry was performed by MarketResponse Nederland BV. The objective was to get an overview of the current perception and the future view of the profession. The response was 37%. Most respondents (66%) were practitioners, 7% were active in research or teaching institutions, 5% were governmental employees, 5% were employed in industry, and 17% did not belong to any of these categories (retired, unemployed etc.). Forty-seven per cent of the veterinarians practised mainly sm...
Weese JS, Staempfli HR, Prescott JF.An environmental survey of a veterinary teaching hospital for the presence of Clostridium difficile was performed using contact plates and cycloserine-cefoxitin-fructose with 0.1% sodium taurocholate agar. Clostridium difficile was isolated from 24 of 381 sites (6.3%). Growth was obtained from 4.5% (9/202) of sites sampled in the Large Animal Clinic, from 8.1% (13/160) of sites within the Small Animal Clinic, and from 20% (2/10) of sites sampled elsewhere. Fourteen of 21 strains tested produced toxins in vitro. A geographic association was found with areas in the large animal clinic where noso...
Moncayo AC, Edman JD, Turell MJ.The effect of eastern equine encephalomyelitis (EEE) virus on the survivorship of Aedes albopictus (Skuse), Anopheles quadrimaculatus Say, and Coquillettidia perturbans (Walker) was determined experimentally. Female mosquitoes were allowed to feed on EEE viremic chicks, and survival rates were compared for infected and uninfected mosquitoes. Additionally, the survival of female Cq. perturbans and An. quadrimaculatus intrathoracically (i.t.) inoculated with EEE was compared with controls receiving diluent inoculations. Infection with EEE significantly reduced survival in Cq. perturbans compared...
Bice DE, Seagrave J, Green FH.Asthma is now recognized to be a chronic inflammatory disease that affects the whole lung. Incidence appears to be increasing despite improved treatment regimens. There is substantial epidemiological evidence suggesting a relationship between the incidence and severity of asthma (e.g., hospitalizations) and exposure to increased levels of air pollution, especially fine and ultrafine particulate material, in susceptible individuals. There have been a few studies in animal models that support this concept, but additional animal studies to test this hypothesis are needed. However, such studies mu...
Wittmann EJ, Baylis M.Changes in the distribution and abundance of insects are likely to be amongst the most important and immediate effects of climate change. We review here the risk that climate change poses to the UK's livestock industry via effects on Culicoides biting midges, the vectors of several arboviruses, including those that cause bluetongue (BT) and African horse sickness (AHS). The major old-world vector of BT and AHS viruses, C. imicola, occurs in southern Europe and will spread further north as global temperatures increase. It is unlikely, however, that in the foreseeable future it will reach and be...
Sarma PN, Tang YJ, Prindiville TP, Osborne PD, Jang S, Silva J, Cohen SH.In order to determine genetic relatedness of Bacteroides fragilis isolates from different clinical sources, arbitrarily primed polymerase chain reaction (PCR) (AP-PCR) was used to compare 17 strains isolated from patients with inflammatory bowel disease (IBD) and 20 strains isolated from foals with diarrhea. Three reference ATCC strains were also analyzed. Eighteen unique types were identified with a 22-mer arbitrary primer (ERIC-2) among the 20 patient isolates. Types 1 (enterotoxigenic) and 9 (nonenterotoxigenic), were each found in the stools of two patients. All other isolates showed a dis...
Cruz I, Vinhas AR, Dubey JP, Cardoso L, Cotovio M, Lopes AP.Neospora spp. are intracellular protozoa with worldwide distribution and closely related to Toxoplasma gondii, which can infect a variety of mammals including horses. From September 2013 to June 2014, 185 horses from northern, central and southern parts of mainland Portugal were randomly sampled and tested for detection of immunoglobulin (Ig) G antibodies to Neospora spp. using an indirect multi-species enzyme-linked immunosorbent assay (ELISA) commercial test (ID Screen® Neospora caninum Indirect Multi-species; ID.vet Innovative Diagnostics, Grabels, France). Two horses (1.1%; CI: 0.1-3.8%),...
Baker EF, Sasso DR, Maness K, Prichard WD, Parker RL.In 1971, more than 370 horses in south Texas were studied with respect to their clinical, virologic, and neutralizing antibody responses to vaccination with Venezuelan equine encephalomyelitis (VEE) strain TC-83. This study confirms reported findings that the vaccine used in the 1971 epizootic in the lower Rio Grande Valley of Texas was safe and efficacious. Vaccinal virus viremia titers were generally below the postulated infection threshold of epizootic vectors. In general, reactions to the vaccine were minimal and transient, with no observed abortions or deaths attributable to use of the va...
Ribbeck R, Heide H, Schicht W, Hiepe T.Observations were carried out from May 1977 to May 1980 on occurrence, fauna, and seasonal dynamics of Gasterophilus spp. in 2,539 horses for butchering from all districts of the German Democratic Republic and also in 79 horses after control against gasterophilosis. 99.98% of the 13,742 second and third instar larvae of horses for butchering were Gasterophilus intestinalis, only 0.02% Gasterophilus nasalis. Out of 7,765 larvae passed after control measures Gasterophilus intestinalis dominated with more than 96%. Only in four districts of the German Democratic Republic Gasterophilus nasalis was...
Wilson SJ, Taylor J, Gibson J, McKenzie R.A dense population of Pimelea trichostachya plants (Family Thymelaeaceae) in pasture poisoned a horse herd in southern inland Queensland in October-November 2005. Plant density was 2 to 45 g wet weight/m(2) (mean 16 g/m(2)) from 5 to 69 plants/m(2) (mean 38 plants/m(2)) representing 3 to 20% (mean 9%) of the volume of pasture on offer. Ten of 35 mares, fillies and geldings were affected. Clinical signs were loss of body weight, profound lethargy, serous nasal discharge, severe watery diarrhoea and subcutaneous oedema of the intermandibular space, chest and ventral midline. Pathological finding...
Grewar JD, Porphyre T, Sergeant ES, Theresa Weyer C, Thompson PN.An African horse sickness (AHS) outbreak occurred in March and April 2016 in the controlled area of South Africa. This extended an existing trade suspension of live equids from South Africa to the European Union. In the post-outbreak period ongoing passive and active surveillance, the latter in the form of monthly sentinel surveillance and a stand-alone freedom from disease survey in March 2017, took place. We describe a stochastic scenario tree analysis of these surveillance components for 24 months, starting July 2016, in three distinct geographic areas of the controlled area. Given that AH...
Akkmeteli MA.Although mycotoxicoses attract more and more attention, the epidemiology of these diseases is still not adequately studied. The author devotes his study to certain diseases. In addition to the diseases whose mycotoxic nature is in no doubt, he conditionally includes certain diseases whose mycotoxic causation needs further proof. The author has assigned stachybotryotoxicosis and alimentary toxic aleukia or fusariotoxicosis to the first category and endemic nephropathy and primary liver-cell carcinoma to the second. His intention in adopting this approach is to establish the common features and ...
Passantino A, Giannetto C, Passantino L, Piccione G.The Council of Europe's activities in the field of animal welfare are particularly noteworthy and comprise the elaboration of several norms for the protection of animals. Concerning the specific European Directive, Regulations or Convention for the protection of animals, the Authors underline the missing of specifics recommendations concerning the welfare of sport horses and especially of trotters. Guidelines are reported by regulation of equestrian sports. The paper's purpose is to give practical elements to individuate the welfare state and to promote a clear regulation on welfare, care and ...
Bush AM, Westneat S, Browning SR, Swanberg J.Occupational illnesses are inadequately reported for agriculture, an industry dominated by a vulnerable Hispanic population and high fatal and nonfatal injury rates. Work-related illnesses can contribute to missed work, caused by a combination of personal and work factors, with costs to the individual, employer, and society. To better understand agricultural occupational illnesses, 225 Hispanic horse workers were interviewed via community-based convenience sampling. Descriptive statistics, bivariate analyses, and log binomial regression modeling were used to: (1) describe the prevalence of mis...
Seahorn JL, Slovis NM, Reimer JM, Carey VJ, Donahue JG, Cohen ND.To identify factors significantly associated with an epidemic of fibrinous pericarditis during spring 2001 among horses in central Kentucky. Methods: Case-control study. Methods: 38 horses with fibrinous pericarditis and 30 control horses examined for other reasons. Methods: A questionnaire was developed to solicit information regarding a wide range of management practices and environmental exposures from farm owners or managers. Results: The following factors were found in bivariate analyses to be significantly associated with an increased risk of pericarditis: being from a farm with mares an...
Pollard D, Grewar JD.Police-recorded road injury data are frequently used to approximate injury risk for different road user groups but a detailed analysis of incidents involving ridden horses has not previously been conducted. This study aims to describe human injuries resulting from interactions between ridden horses and other road users on public roads in Great Britain and identify factors associated with severe to fatal injuries. Police-recorded road incident data involving ridden horses (2010-2019) were extracted from the Department for Transport (DfT) database and described. Multivariable mixed-effects logis...
Hall SE, Nixon B, Aitken RJ.Feral horses are a significant pest species in many parts of the world, contributing to land erosion, weed dispersal and the loss of native flora and fauna. There is an urgent need to modify feral horse management strategies to achieve public acceptance and long-term population control. One way to achieve this is by using non-surgical methods of sterilisation, which are suitable in the context of this mobile and long-lived species. In this review we consider the benefits of implementing novel mechanisms designed to elicit a state of permanent sterility (including redox cycling to generate oxid...
Among the protozoa of the genus Sarcocystis (Apicomplexa; Sarcocystidae), Sarcocystis bertrami (syn. Sarcocystis fayeri) is an obligate intracellular parasite of donkeys and horses with worldwide distribution. Here, we report the detection of S. bertrami in naturally infected donkeys from southern Italy and describe their structure by light microscopy (LM) and transmission electron microscopy (TEM). Protozoal cysts were detected both morphologically and molecularly in skeletal muscles of 28.57% (40/140) donkeys. Mature cysts of S. bertrami were found in skeletal muscle measuring 31-102 μm l...
Menzies-Gow NJ, Young NJ.Enterococcus faecium, a major cause of potentially life-threatening hospital-acquired human infections, can be resistant to several antimicrobials, such that streptogramin quinupristin-dalfopristin (Q/D) is one of the few antibiotics still effective. Consequently use of the streptogramin virginiamycin as an animal growth promoter was banned in the EU in 1999 as some believed this contributed to the emergence of Q/D resistant E. faecium. Virginiamycin is advocated for preventing equine pasture-associated laminitis, but its effect on equine faecal bacterial Q/D resistance has not been determined...
Kropich-Grant JN, Wiley KE, Manyweathers J, Thompson KR, Brookes VJ.Hendra virus disease (HeVD) is an emerging zoonosis in Australia, resulting from the transmission of Hendra virus (HeV) to horses from Pteropus bats. Vaccine uptake for horses is low despite the high case fatality rate of HeVD in both horses and people. We reviewed evidence-based communication interventions to promote and improve HeV vaccine uptake for horses by horse owners and conducted a preliminary evaluation of potential drivers for HeV vaccine uptake using the Behavioural and Social Drivers of Vaccination (BeSD) framework developed by the World Health Organization. Six records were eligi...
Dumasia MC, Houghton E, Hyde W, Greulich D, Nelson T, Peterson J.Studies related to the in vivo biotransforrmation and urinary excretion of fenspiride hydrochloride in the horse are described. After oral administration, the drug is metabolised by both phase I functionalisation and phase II conjugation pathways. Following enzymatic deconjugation, fenspiride and its phase I metabolites were isolated from post-administration biofluids using bonded co-polymeric mixed mode solid-phase extraction cartridges to isolate the basic compounds. Following trimethylsilylation (TMS), the parent drug and metabolites were identified by capillary gas chromatography-mass spec...
Rebecca PH, Linda P.Although the number of small-scale farms is increasing in North America and Europe, few studies have been conducted to better understand environmental management in this sector. We investigate this issue by examining environmental management on horse farms from both the perspective of the "expert" extension educator and horse farm operator. We conducted a Delphi survey and follow-up interviews with extension educators in Indiana and Kentucky. We also conducted interviews and farm assessments with 15 horse farm operators in the two states. Our results suggest a disconnection between the percept...
Wilson SJ, Ward MP.Hendra virus (HeV), a potentially fatal zoonotic disease spread by flying foxes, to date has always infected humans via a spillover event from equine HeV infection. In a theoretical case study, we compared the impacts of two different HeV prevention strategies - vaccination and flying fox roost removal - using a recently developed framework that considers different stakeholder group perspectives. The perspectives of the four selected stakeholder groups regarding intangibles were inferred from public discussions and coverage in the media. For all stakeholder groups, the option to vaccinate hors...
Paillot R, Regourd E, Behr-Gross ME.Equine influenza (EI) is an important respiratory disease of horses, with welfare and economic consequences. Vaccination remains one of the most efficient prevention methods available. Equine influenza virus (EIV) is constantly evolving and consequently EI vaccines need to be updated on a regular basis. In 2010, the World Organisation for Animal Health (OIE) Expert Surveillance Panel (ESP) on EI provided a new recommendation for EI vaccine strain composition, including the incorporation of representative EIV strains of both Florida Clade 1 and Clade 2 sub-lineages (FC1 and FC2, respectively). ...
Kamhieh S, Hodgson J, Bode L, Ludwig H, Ward C, Flower RL.Borna disease virus (BDV) is a unique RNA virus that is a cause of neurological disease in horses, sheep and cats. The finding that BDV also infects humans has raised concern related to the impact of infection with this virus. The extent to which BDV may be endemic in geographical regions outside Europe is of interest in management of international movement of animals including horses. Sera from Australian horses (N = 553) sampled in Sydney, New South Wales (NSW), were analysed for BDV antigen, circulating immune complexes (CICs), and antibodies by monoclonal antibody-based ELISAs. One-tenth o...
Giangaspero A, Lia R, Vovlas N, Otranto D.A survey on the prevalence of Thelazia spp. in the province of Bari (Apulia region, Italy) in slaughtered native horses was conducted from June 20, 1995 to April 3, 1996. Both eyes from 409 ten-month- to 4-year-old native animals were examined. Sixty horses (14.7%) were found parasitized by Thelazia lacrymalis. Three hundred-sixty one parasite specimens (220 females, 99 males and 42 larvae) were collected with a mean count burden of 6.0-5.1 (range 1 to 20) per head. T. lacrymalis specimens were found free in the conjunctiva and behind the nictitancte, in the excretory ducts of the Harderian gl...
Morier L, Cantelar N, Soler M.Eastern Equine Encephalitis (EEE) was in Cuba before the 1940s; the virus has been isolated from horses, birds, and rodents during epizootic as well as interepizootic periods. The only isolation of Western Equine Encephalitis (WEE) virus was from a sick pigeon found in the vicinity of Havana University. Both viruses can cause human disease; the isolation of WEE virus from the centre of an urban area emphasises the need for the prompt isolation and rapid identification of these agents. The object of this work was to compare the sensitivity of a continuous cell line (XL-2) from the toad, Xenopus...
Makowiecki D, Chudziak W, Szczepanik P, Janeczek M, Pasicka E.Knowledge about horses from early medieval (10th-13th c.) Poland has been largely based on historical and archaeological data. Archaeozoological information has only been used to a limited extent. Therefore, this article aims to present the current state of knowledge on this subject, drawing on archaeozoological data from studies of horse bones. Apart from confirming earlier reflections regarding the sacred significance of the horse, additional information was obtained about specific individuals who were the subject of magical treatments. It turned out that sites with horse skeletons and skull...
Ward A, Stephen K, Argo C, Watson C, Harris P, Neacsu M, Russell W, Grove-White D, Morrison P.During the lockdown phase of the COVID-19 pandemic, equestrian stakeholders faced a dilemma whereby they were required to balance caring for the welfare of horses with adapting to the restrictions imposed to protect public health. The present study investigated the impact of the pandemic on the wellbeing of a sample of industry stakeholders, including horse owners, equine veterinarians, farriers and welfare centre managers ( = 26) using a qualitative methodology. Findings from the interviews indicated that the mental health and wellbeing of veterinarians and horse owners was negatively affecte...
Kwak ML, Schubert J.Although forensic parasitology remains in its infancy compared with more developed fields like forensic entomology, parasites can be useful forensic indicators. We present the case of an individual who disobeyed animal health legislation and crossed animal quarantine boundaries and two state lines with a cattle tick (Rhipicephalus australis) infested horse. Following recognition of the infestation by animal health officers, the individual asserted that the infestation had occurred either during transport or upon arrival at the site of discovery, and that they had not contravened quarantine leg...
Stanbouly D, Besmer AV, Chuang SK.The purpose of our study is to assess the severity of craniomaxillofacial injuries from horseback-riding accidents. Methods: This is a 20-year retrospective cross-sectional study of the National Electronic Injury Surveillance System. Injuries from the activity of horseback-riding were included if they occurred in the craniomaxillofacial complex. Study predictors were derived from both patient and injury characteristics. The study outcome was the presence or absence (probability) of hospital admission from the emergency department. A multiple logistic regression model was created to model the o...
Yang J, Wang Y, Cui X, Zhang Y, Yu Z.Huge numbers of microorganisms reside in livestock faeces and constitute one of the most complex microbial ecosystems. Here, faecal microbial communities of three typical livestock in Xilingol steppe grassland, i.e. sheep, cattle, and horse, were investigated by Illumina MiSeq sequencing and quantitative real-time polymerase chain reaction (qPCR). Firmicutes and Bacteroidetes comprised the majority of bacterial communities in three livestock faeces. Sordariomycetes, Leotiomycetes, and Dothideomycetes were dominant in fungal communities, as well as Methanobacteria and Methanomicrobia were domin...
Müntener C, Kupper J, Naegeli H, Gassner B.A total of 292 adverse reactions to veterinary medicinal products were reported during the year 2015. This represents an increase of 9% compared to the previous year (268 reports). Similar to previous years, most of the reactions reported were linked to the use of antiparasitics (55.1%), non-steroidal anti-inflammatory products (8.9%) or antiinfectives (9.3%). The affected animal species were primarily dogs (198 reports) and cats (42 reports), followed by cattle (31 reports) and horses (8 reports). Additional 42 reports were provided within the frame of consultations with Tox Info Suisse in Z...
Jacobsen ABJE, Damborg P, Hopster-Iversen C.Horses may be carriers of important resistant bacteria like methicillin-resistant staphylococci. Such bacteria can potentially threaten both equine and public health, but little is known about predisposing factors like antimicrobial usage patterns in equines. Objectives of this study were to investigate the antimicrobial usage practices by Danish equine practitioners as well as factors impacting usage. A total of 103 equine practitioners filled in an online questionnaire. When asked to explain their typical treatment of six clinical case scenarios, only 1% and 7% of respondents prescribed syst...
Sebek Z, Wallner H, Sixl W, Kaaserer G, Valová M.Results are presented of a serological examination of 1,547 domestic animals (cattle, pig, sheep, horse, goat, dog, cat) from 9 Tyrolian districts (Austria), performed in order to disclose the incidence of leptospirosis. Completely significant titres were domonstrated by means of the MAL test in the serotypes icterohaemorrhagiae or copenhageni, sorex-jalna, bratislava, sejroe and saxkoebing. In addition, antibodies were confirmed against L. bataviae, L. pomona, L. tarassovi and L. bulgarica, but the titres were insignificant. Of the animals examined, 7.2% gave positive reactions in titres of 1...
