Haase L, Winter J, Grummt S, Sedlmayr M, Sedlmayr B.Many people seek health-related information online, not only for themselves but also on behalf of others who cannot articulate their symptoms. This proxy information-seeking behavior is particularly relevant for animal owners, who must interpret their animals' symptoms without direct verbal feedback. While online health information-seeking in the context of one's own health is well-studied, the specific challenges of searching by proxy, especially for animal health information, remain largely unexplored. Unassigned: This study aimed to determine the specific information needs and search behavi...
Ye T, Li XM, Tan WX, Wang CL, Jiang J, Zhao Q.Toxoplasmosis is a zoonotic infectious disease caused by T. gondii, a widely distributed obligate intracellular parasite. It has received widespread attention because it can infect a large number of domestic and wild animals, thereby posing a threat to public health and the economy on a global scale. Among them, equine animals are critical intermediate hosts. However, studies on T. gondii infection in equine animals are currently not systematic on a global scale. For this purpose, we conducted a systematic review and meta-analysis. Methods: This study searched for relevant studies in six signi...

Results: Fifty-seven horse and/or stable owners completed the que...
Burns JJ, MacMillan KM.The Standardbred racing industry plays an important role in the North American economy and is expected to continue operating and growing. However, public perception is often unfavorable, with increasing concern about the health and welfare of Standardbred racehorses. Despite this, limited research has examined Standardbred well-being. To address this gap, a survey of equine trainers on Prince Edward Island (PEI) was conducted to evaluate key health and welfare issues during racing careers. Results showed that over one quarter of respondents had at least one horse displaying stereotypic behavio...
Markowitz JS.Equibase (EQB) race charts provide the official record of North American Thoroughbred races and often document catastrophic injury, euthanasia, or equine-ambulance transport. Because chart documentation and regulatory classification differ, fatalities occurring > 72 hours after a race fall outside international regulatory definitions applied by the Equine Injury Database (EID) and may not appear in EID aggregates. EQB charts confirm horse identity, race participation, finishing status, and last recorded start. Horseracing Wrongs (HRW), an advocacy group, publishes horse-level fatality data tha...
Dundjerovic I, Sneddon LU.Animal welfare concerns both the physical and mental wellbeing of animals so the assessment of animals kept in captivity, for example zoos, is important and necessary both legally and ethically. Good welfare is especially vital when breeding endangered species as stress impairs reproductive investment. As zoos often have high numbers of visitors, it is important to know if humans and the associated noise might influence the animals' welfare. The aim of this study was to investigate whether the presence of visitors and activities offered to the visitors caused a stress response in horses housed...
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...

Hardefeldt L, Thomas K, Page S, Norris J, Browning G, El Hage C, Stewart A, Gilkerson J, Muscatello G, Verwilghen D, van Galen G, Bauquier J....The growing problem of antimicrobial resistance also affects equine veterinarians with increasing frequency. Antimicrobial stewardship and responsible prescribing are essential for a future in which effective antimicrobials are available, as it is unlikely that new antimicrobials will become available for use in horses. While antimicrobials are commonly used to treat equine infections, complications with therapy are also relatively common. Antimicrobial-associated diarrhoea, immune-mediated diseases, and nephrotoxicity have been reported as sequelae of antimicrobial therapy in equine practice....

Rosanowski SM, Milne H, Pearce P, McDonald N, Zobel G, McFadden A.An essential component of a timely response to a disaster event or disease outbreak is an accurate understanding of the population at risk, its location, and the owners' contact details. In equines, this can be achieved through individual identification, via microchipping, and the registration of these individuals in a centralised database. This review outlines the development by the New Zealand Equine Health Association (NZEHA) of a centralised database for equines in New Zealand, the National Equine Identification and Traceability (NEIT) system, which is built using Companion Animal New Zeal...
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...
McLachlan AD, Woolford L.Chlamydia psittaci was detected by real-time PCR in the lung, liver and kidney of an equine foetus that had aborted in South Australia in August 2023. The corresponding microscopic lesions included lymphocytic and histiocytic chorionitis, necrosis of placental villi associated with bacteria in the cytoplasm of trophoblastic epithelial cells, and multiple microgranulomas in the liver. Equine chlamydial abortion had not been diagnosed previously in South Australia. Eight days after examining the foetus and placenta, the veterinary pathologist developed fever and subsequently was admitted to hosp...
Linnegar B, Hoegh A, McCallum H, Peel AJ.Anthropogenic climatic and landscape change can drive behavioural shifts in wildlife and thus lead to increased risk of pathogen exposure for humans and domestic animals. While spillover research often focuses on the reservoir hosts or ongoing transmission in humans, livestock and companion animals can play important roles as bridging and amplifying hosts, facilitating the emergence of highly pathogenic diseases. Objective: To investigate the distribution and density of domestic horses in the context of their role as bridge hosts for Hendra virus and build models to study zoonotic emergence. M...
