Topic:Public Health
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.
A novel ready-to-use loop-mediated isothermal amplification (LAMP) method for detection of Burkholderia mallei and B. pseudomallei. Glanders and melioidosis are contagious zoonotic diseases caused by Burkholderia mallei and B. pseudomallei, respectively. Bacterial isolation and polymerase chain reaction (PCR) have been used to detect these bacteria in animals suspected of infection; however, both methods require skilled experimental techniques and expensive equipment. These obstacles make it difficult to diagnose B. mallei and B. pseudomallei infections in areas where reagents and equipment are difficult to procure. To solve this problem, we developed an easy and ready-to-use dried-format diagnostic tool based on loop-medi...
Eastern equine encephalitis virus: Pathogenesis, immune response, and clinical manifestations. Eastern equine encephalitis virus (EEEV) is a lethal transmitted by mosquitoes that primarily cycles between birds. Although rare, infections in humans and horses are associated with high mortality rates and severe neurological effects. Climate change appears to be increasing the spread of this virus. This study aims to provide a comprehensive analysis of EEEV, including its transmission dynamics, pathogenesis, induced host immune response, and long-term impacts on survivors. It also highlights the virus's unique immune evasion strategies that complicate disease management and contribute to ...
De-extinction beyond species: Restoring ecosystem functionality through large herbivore rewilding. This perspective positions rewilding as a novel approach to ecosystem restoration, emphasising the restoration of natural processes to create self-willed ecosystems. Central to European rewilding is the de-domestication of cattle and horses to act as functional analogues of the extinct aurochs and wild horses. This de-extinction pathway shifts the focus from the loss of species to the loss of their ecological roles caused by human actions commencing millennia ago. The focus on restoring functional effects provides a strong policy rationale for large herbivore de-domestication, aligning with na...
Detection of equine influenza virus gene in the air around infected horses. Equine influenza virus (EIV) can be transmitted by inhalation of aerosolized droplets, direct contact, and contaminated fomites. However, to our knowledge, there are no reports of the recovery of EIV from the air surrounding infected horses. Here, we evaluated whether EIV can be recovered from the air in the stalls of experimentally infected horses by using an air sampler. Furthermore, we examined whether rapid molecular test kits with reaction times of less than 30 min can detect EIV from air samples for potential field application. Two horses kept in individual stalls were experimentally i...
Emerging biofilm formation and disinfectant susceptibility of ESBL-producing Klebsiella pneumoniae. Klebsiella pneumoniae is an opportunistic pathogen responsible for various infections in humans and animals. It is known for its resistance to multiple antibiotics, particularly through the production of Extended-Spectrum Beta-Lactamases (ESBLs), and its ability to form biofilms that further complicate treatment. This study aimed to isolate and identify K. pneumoniae from animal and environmental samples and assess commercial disinfectants' effectiveness against K. pneumoniae isolates exhibiting ESBL-mediated resistance and biofilm-forming ability in poultry and equine farms in Giza Governorat...
3′-deoxytubercidin: A potent therapeutic candidate for the treatment of Surra and Dourine. Surra and Dourine are widespread diseases caused by two protozoan parasites Trypanosoma brucei evansi and Trypanosoma brucei equiperdum, respectively. A wide range of animals including camels, horses, cattle and buffaloes are susceptible to infection. These diseases pose a significant socio-economic burden, primarily due to the limited therapeutic options and the complications associated with toxicity and drug resistance, making disease management particularly challenging. This study evaluated the potential of 3'-deoxytubercidin, a previously identified antitrypanosomal nucleoside, as a therap...
A model-based approach to evaluate the effect of vaccination of the herd on transmission of equine herpesvirus 1 in naturally occurring outbreaks. Equine herpesvirus 1 (EHV-1) infection is the cause of high impact disease syndromes, affecting the global horse industry. The effect of vaccination on transmission dynamics of EHV-1 in naturally occurring outbreaks is not quantified. Our aims were to estimate R for EHV-1 in equine populations from outbreak data, and evaluate the effect of vaccination status of the herd on R through a systematic review, model-based estimations and meta-analysis. A literature search for outbreak reports was carried out. Depending on available data, the early epidemic growth rate (GR) or final attack rate (AR) a...
Molecular basis for shifted receptor recognition by an encephalitic arbovirus. After decades of inactivity throughout the Americas, western equine encephalitis virus (WEEV) recently re-emerged in South America, causing a large-scale outbreak in humans and horses. WEEV binds protocadherin 10 (PCDH10) as a receptor; however, nonpathogenic strains no longer bind human or equine PCDH10 but retain the ability to bind avian receptors. Highly virulent WEEV strains can also bind the very low-density lipoprotein receptor (VLDLR) and apolipoprotein E receptor 2 (ApoER2) as alternative receptors. Here, by determining cryo-electron microscopy structures of WEEV strains isolated from...

The most recent large outbreak occurred in South America from November 2023 to April 2024. We identified and genetically characterized Uruguayan strains during this outbreak to understand their evolutionary trends and rapid expansion. We obtained genomes from 15 strains using a novel multiplex PCR assay combined with next-generation Illumina sequencing. The phylogenetic analysis revealed that viruses from Uru...
Protocol to implement and evaluate a culturally secure, strength-based, equine-assisted learning program, “Yawardani Jan-ga” (horses helping), to support the social and emotional wellbeing of Australian aboriginal children and young people. Australian Aboriginal people experience stressors from inequalities across crucial social determinants, including deep and entrenched disadvantage and exclusion. The impact of unaddressed historical issues is pervasive and intergenerational. The disproportionate rates of Aboriginal youth suicide, juvenile detention and imprisonment highlight the inadequacy of existing social and emotional wellbeing programs and services for Aboriginal children and young people. There is increasing recognition in Australia that aligning social and emotional wellbeing interventions with Western values and concep...
Effects of climate change on the occurrence and distribution of Western equine encephalitis virus in South America. The Western equine encephalitis virus (WEEV) is a globally relevant vector-borne pathogen that causes encephalitis. The role of environmental variables in the epidemiology of WEEV has become greater in the context of climate change. In December 2023, a significant resurgence of WEEV began in South America, with major ongoing outbreaks in Argentina and Uruguay. In this study, we employed a machine learning algorithm to model the distribution of WEEV in South America, considering both present and future scenarios. Methods: Ecological retrospective study. Methods: We conducted a modelling study t...

West Nile Virus: An Update Focusing on Southern Europe. West Nile Virus (WNV) is a zoonotic, vector-borne pathogen affecting humans and animals, particularly in Europe. The virus is primarily transmitted through mosquitoes that infect birds, which serve as the main reservoirs. Humans and horses are incidental hosts. This review focuses on the epidemiology of WNV in southern Europe, particularly its increasing prevalence. Methods included an extensive literature review and analysis of recent outbreaks. WNV is largely asymptomatic in humans, but a small percentage can develop West Nile neuroinvasive disease (WNND), leading to severe neurological symp...
Eastern Equine Encephalitis Virus: The Importance of Metabolism and Aging. Eastern equine encephalitis virus (EEEV) is a mosquito-transmitted alphavirus that, among humans, can cause a severe and often fatal illness. The zoonotic EEEV enzootic cycle involves a cycle of transmission between and avian hosts, frequently resulting in spillover to dead-end vertebrate hosts such as humans and horses. Interestingly, it has been described that the W132G mutation of the very low-density lipoprotein receptor (VLDLR), the receptor of EEEV, significantly enhanced the VLDLR-mediated cell attachment of EEEV. The patient's metabolism plays a pivotal role in shaping the complex lan...
Distinct molecular epidemiology of resistances to extended-spectrum cephalosporins and carbapenems in Enterobacter hormaechei in cats and dogs versus horses in France. Enterobacter hormaechei is an important pathogen in humans and animals, which, in addition to its intrinsic AmpC, can acquire a wide variety of genes conferring resistances to extended-spectrum cephalosporins (ESCs) and carbapenems (CPs). In France, human clinical outbreaks of E. hormaechei resistant to ESC or carbapenem were reported. Objective: To study E. hormaechei isolates from cats and dogs (=59) as well as from horses (n = 55) presenting a non-susceptible phenotype to beta-lactams in order to determine which clones, resistance genes and plasmids are circulating in France.

Global prevalence of Borrelia burgdorferi and Anaplasma phagocytophilum coinfection in wild and domesticated animals: A systematic review and meta-analysis. Both Borrelia burgdorferi (Bb) and Anaplasma phagocytophilum (Ap) can infect humans and animals through tick-borne transmission, resulting in zoonosis. Under certain conditions, human infection can lead to Lyme disease (LD) and human granulocytosis (HGA), whereas infection in animals can cause various acute and non-specific symptoms. The combination of Bb and Ap has been reported to increase the disease severity in infected animals. In this systematic review and meta-analysis, we investigated the global diversity of Bb and Ap coinfection in animals and their prevalence and distribution regardi...
[Equine granulocytic anaplasmosis (EGA): Case description and overview of the epidemiological situation with focus on Germany]. Equine granulocytic anaplasmosis (EGA) is a tick-borne disease caused by Anaplasma (A.) phagocytophilum. In Central, Northern, Western, and Eastern Europe, ticks of the Ixodes (I.) ricinus/I. persulcatus complex, in Germany mainly I. ricinus, are considered as vectors. Ixodes ricinus ticks show peaks of activity during the spring and summer months, particularly April to July. Changing climatic conditions, however, have meanwhile led to a year-round risk of tick exposure and thus infections with A. phagocytophilum. The presented case report underlines the seasonal peak phase of the infection ri...

Equine Encephalomyelitis Outbreak, Uruguay, 2023-2024. We report the genomic analysis from early equine cases of the Western equine encephalitis virus outbreak during 2023-2024 in Uruguay. Sequences are related to a viral isolate from an outbreak in 1958 in Argentina. A viral origin from South America or continuous enzootic circulation with infrequent spillover is possible.
bla SED-1 beta-lactamase-producing Citrobacter sedlakii isolated from horses and genomic comparison with human-derived isolates. We aim to detect beta-lactamase-producing Citrobacter sedlakii from horses and compare the genomic characteristics with isolates from humans. Results: We characterized phenotypically and genotypically nine C. sedlakii isolates from the feces of horses and then compared them to human-derived isolates using whole genome sequencing and phylogenomic methods. Seven isolates (7/9) were ampicillin-resistant, while at least one isolate was resistant to ceftriaxone, gentamicin, meropenem, and streptomycin. All nine isolates were carriers of the chromosomal-mediated blaSED-1 beta-lactamase gene, which...
Working horse welfare in Senegal is linked to owner’s socioeconomic status, their attitudes and belief in horse sentience. The role that working equids play in both rural and urban communities in low and middle-income countries is invaluable. They contribute to daily tasks such as carrying food, water and people, support income generation, and are of social and cultural importance. Despite their importance, global standards of working equid welfare are low. Many variables can impact the welfare status of animals under human care, but often specific factors are explored in isolation. Factors can include, but are not limited to an owner's socioeconomic status and their attitudes and beliefs towards animals. In this ...
