Joachim A, Cavalleri JV, Berger S.Equine granulocytic anaplasmosis (EGA) and equine piroplasmosis (EP) are triggered by tick-borne pathogens - the intracellular bacterium Anaplasma phagocytophilum and the intracellular protozoa Babesia caballi and Theileria equi. These pathogens attack cells in the blood stream and cause similar clinical symptoms and changes in laboratory values. Although the treatment principles are naturally different, similarities in prophylaxis exists due to the transmission route. Tick transmitted pathogens can play a greater role in equine medicine in the future due to various factors, such as the tenden...

Muko R, Matsuda H, Oikawa MA, Shin T, Matsuda K, Sato H, Sunouchi T, Tanaka A.Histidine-rich glycoprotein (HRG) is an abundant plasma protein that has been identified in most mammals. We first identified whole genome sequence of equine HRG (eHRG) and succeeded to purify eHRG from plasma of horses. Since HRG interacts with various ligands, this protein is thought to be involved in immune response, coagulation, and angiogenesis. Systemic inflammatory response syndrome (SIRS) is characterized as a non-specific, clinical, pro-inflammatory immune response that damage organs and tissues in the host. Recent reports revealed that blood HRG levels in human patients with SIRS are...
Camargo Garbin L, Lopez C, Carmona JU.In the 1990s, the role of platelets in inflammation and tissue healing was finally recognized. Since then, the clinical use of platelet-derived products (hemocomponents), such as, platelet-rich plasma (PRP), markedly increased. The promise of a more economical option of a disease-modifying treatment led to the intensive and continuous research of PRP products and to its widespread clinical use. A number of protocols and commercial kits have been developed with the intention of creating a more practical and reliable option for clinical use in equine patients. Still, the direct comparison betwee...

Lensing R, Wirth C, Thünker F, Merle R, Barton AK.Gastric pH is a key factor in the development of equine squamous gastric disease (ESGD). Although acid injury is unlikely the primary cause of equine glandular gastric disease (EGGD), low pH may promote mucosal damage. Gastric pH is influenced by roughage uptake, as chewing increases the alkaline saliva production. The proton pump inhibitor omeprazole is currently recommended by the American/European College of Veterinary/Equine Internal Medicine (ACVIM/ECEIM) for ESGD and EGGD. We hypothesized that dental disorders decrease saliva production and gastric pH, predisposing horses to EGUS. Gastro...

Rodrigues LT, Segabinazzi L, Frasson M, Dell'Aqua C, Carmo MT, Takahira RK, Alvarenga M, Papa F.Although protocols for superovulation have been described in horses, this technique has been discouraged due to the low embryo recovery rates in superovulated mares. The reason for these poor results is poorly understood, but the formation of a blood clot in the ovulation fossa following ovulations has been hypothesized. Therefore, this study aimed to assess the safety and effect of periovulatory anticoagulant therapy on embryo recovery of superovulated mares. In experiment 1, five mares were assigned to receive five anticoagulant treatments in a crossover design: intravenous injections of 150...
Luan Y, Zhong L, Li C, Yue X, Ye M, Wang J, Zhu Y, Wang Q.Polydactyly was recorded before 100 BCE and attracted widespread interest because of its relationship to limb health and ancestral traits in horses. However, the underlying reasons for the development of polydactyly remain unclear. To search for polydactyly-related genes, we utilize a paternal half-sib family and screen for variants that match the mode of inheritance. Through this screening process, 77 variants in 65 genes are filtered. A missense variant (EqCab3.0 chr4: <107353368> A > G) (rs1138485164) in the 3rd exon of LMBR1 is identified as a source of amino acid sequence variatio...
