Equine health encompasses the study and management of diseases, disorders, and overall well-being of horses. It involves understanding various physiological systems, preventive care, and treatment strategies to maintain optimal health in equine populations. Common areas of focus include nutrition, infectious diseases, orthopedic conditions, and reproductive health. Research in equine health aims to advance knowledge on diagnostic methods, therapeutic interventions, and management practices that improve horse welfare and performance. This page collects peer-reviewed research studies and scholarly articles that explore the diverse aspects of equine health, offering insights into current findings and advancements in the field.
This study was designed to investigate whether horses with clinical signs of back pain due to suspected soft tissue injuries were affected by polysaccharide storage myopathy (PSSM). Diagnosis of PSSM in muscle biopsies obtained from the M. longissimus lumborum of 5 showjumpers and 4 dressage horses with a history of back pain is reported. M. longissimus lumborum biopsies of these horses were characterised histopathologically and in 3/9 cases also by electron microscopy. Observations were compared with M. gluteus biopsies of the same horses, and with M. gluteus biopsies obtained from 6 Standard...
Four horses were evaluated because of hind limb lameness. Two had a distinct gait abnormality at the walk characterized by lateral rotation of the point of the calcaneus and medial rotation of the toe during the stance phase. Nuclear scintigraphy revealed a focal area of intense radioisotope uptake in the caudodistal aspect of the femur in all 4 horses, and 3 of the horses had a corresponding proliferative reaction on the caudodistal cortex of the femur on radiographs. In all 4 horses, a diagnosis of injury to the origin of the gastrocnemius muscle was made. Three of the horses returned to ath...
Two closed horse herds (Old Lot 4 and Field 24), infected since 1966 with Population B small strongyles resistant to thiabendazole (TBZ) and phenothiazine (PTZ), were terminated in February, March, and May, 2005. At necropsy, only the large endoparasites were identified and counted. The number of horses on pasture was 14 (239 days of age to 23 years old) for Old Lot 4 and two (3 to 20 years old) for Field 24. The time of the last antiparasitic treatment, relative to the year (2005) of necropsy, was 26 years for Old Lot 4 and 9 years for Field 24 horses. Gasterophilus intestinalis third instars...
Fifteen horses harboring naturally acquired, patent Parascaris equorum and Oxyuris equi infections were equally allotted to 3 treatment groups given (1) injectable vehicle; (2) injectable ivermectin at the dose rate of 200 microgram/kg of body weight; and (3) injectable ivermectin at the rate of 300 microgram/kg. All treatments were given IM in the neck. All animals were killed 14 days after treatment and examined for the targeted nematodes. Regardless of dose rate, ivermectin proved 100% effective in the removal of adult O equi and P equorum infections. Levels of immature P equorum were decre...
Holmes JC, Arojojoye AS, Awuah SG, Eisenberg R, Fenger CK, Maylin GA, Brewer K, Tobin T.Detomidine, 5-[(2,3-dimethylphenyl)methyl]-1H-imidazole, is a tranquilizer/sedative/analgesic widely used in equine medicine and regulated by several different analyte concentrations of detomidine and its hydroxydetomidine and carboxydetomidine metabolites in plasma and urine. Accurate regulatory quantitation of detomidine at low picogram/mL concentrations requires the availability of a stable isotope internal standard of detomidine; however, to the best of our knowledge, no certified deuterated internal standard of detomidine is commercially available and its synthesis has not been reported. ...
Chen J, Yablon A, Metaxas C, Guedin M, Hu J, Conover K, Simpson M, Ralston SL, Krishnamurthy K, Pelczer I.: There are a few very specific inflammation biomarkers in blood, namely lipoprotein NMe signals of protein clusters (GlycA and GlycB) and a composite resonance of phospholipids (SPC). The relative integrals of these resonances provide clear indication of the unique metabolic changes associated with disease, specifically inflammatory conditions, often related to serious diseases such as cancer or COVID-19 infection. Relatively complicated, yet very efficient experimental methods have been introduced recently (DIRE, JEDI) to suppress the rest of the spectrum, thus allowing measurement of these ...
Zhang Y, Guo X, Yu M, Sun L, Qu Y, Guo K, Hu Z, Liu D, Zhang H, Wang X.Host ANP32 family proteins are crucial for maintaining the activity of influenza RNA polymerase and play an important role in the cross-species transmission of influenza viruses. To date, the molecular properties of equine ANP32 (eqANP32) protein are poorly understood, particularly the mechanisms that affect equine influenza virus (EIV) RNA polymerase activity. Here, we found that there are six alternative splicing variants of equine ANP32A (eqANP32A) with different levels of expression. Further studies showed that these six splicing variants of eqANP32A supported the activity of EIV RNA polym...
Akinniyi OO, Afolabi DO, Mshelia PW, Olakojo TA, Oyenekan IO, Adah O, Osunkoya D, Olaogun SC, Jeremiah OT, Omobowale TO.Dental age estimation in horses is very important in the context of quality healthcare, breeding programs, and welfare management. However, information on the most suitable dental age estimation methods for Nigerian local horses is not available in the literature. We evaluated and compared dental age estimates based on six dental age estimation methods with known chronological ages of Nigerian local horses to establish the most accurate techniques for this population. A cross-sectional study of 180 Nigerian local horses was conducted in Ibadan, Nigeria. Six dental age estimation methods (erupt...
Pigé C, Vaughan B, Reesink HL.To describe principles of ultrasound-guided injection techniques for intralesional delivery of regenerative orthobiologics into equine tendon and ligament core lesions. Unassigned: A university-owned horse and equine cadaver forelimbs. Unassigned: A reproducible protocol for ultrasound-guided injection is demonstrated with the superficial digital flexor tendon used as an example. Following diagnosis of the lesion, the horse should be sedated and the affected limb desensitized with perineural anesthesia. The lesion is identified ultrasonographically in transverse and longitudinal planes, marked...
