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.
Tolerance Induction of Horse Allergy by Horse Contact with Curly Horses. A horse allergic rider completed 60 riding lessons on Curly Horses within six months. This rider has become clinically tolerant to normal horse breeds within this time. This case may indicate that riding and brushing ABCR Curly Horses after 60 riding hours facilitates tolerance induction. Our data indicate that this could be a valid alternative to the common recommendation to strictly avoid horse riding. Eine pferdeallergische Reiterin erhielt 60 Reitstunden auf „Curly Horses“ innerhalb von 6 Monaten. Die Reiterin tolerierte die Allergenexposition mit Pferden anderer Rassen innerhalb diese...
Problems in the Protection of Reintroduced Przewalski’s Horses (Equus ferus przewalskii) Caused by Piroplasmosis. The objectives of our research on equine piroplasmosis were to clarify the prevalence of the piroplasms Babesia caballi and Theileria equi among reintroduced Przewalski's horses (takhi, Equus ferus przewalskii) in comparison with horses (Equus caballus) of nomads from around Hustai National Park in Mongolia and to determine the mortality among takhi during 2012 to 2015. The prevalence of T. equi was high in 2014 at 80% among nomadic horses and 84% among takhi. We found no evidence of B. caballi infection among takhi.

Sera samples were collected fr...
Helminth egg excretion in horses kept under tropical conditions-Prevalence, distribution and risk factors. Increasing levels of anthelmintic resistance observed in equine cyathostomin parasites have led to recommendations of selective anthelmintic treatment strategies to lower the selection pressure favoring resistant populations. This principle is based on determining strongyle fecal egg counts from all herd members, and treating those exceeding a predetermined treatment cutoff. However, epidemiological information is lacking from horses kept under tropical conditions, where parasite burdens may be of a different composition and magnitude compared to those of horses kept under temperate climate co...
