Disease treatment in horses encompasses a range of medical interventions and management strategies aimed at addressing various health conditions affecting equine species. These treatments can include pharmacological approaches, such as the administration of antibiotics, anti-inflammatory drugs, and antiparasitic medications, as well as non-pharmacological methods like physical therapy, dietary adjustments, and surgical procedures. The selection of appropriate treatments depends on the specific disease, its severity, and the individual needs of the horse. This topic brings together peer-reviewed research studies and scholarly articles that explore the efficacy, safety, and advancements in therapeutic options for equine diseases, providing insights into best practices and emerging trends in equine veterinary medicine.
Pan L, Zhang L, Fan D, Zhang X, Liu H, Lu Q, Xu Q.Q fever is the most widespread zoonosis, and domestic animals are the most common sources of transmission. It is not only difficult to distinguish from other febrile diseases because of the lack of specific clinical manifestations in humans, but it is also difficult to identify the disease in C. burnetii-carrying animals because of the lack of identifiable features. Conventional serodiagnosis requires sera from the acute and convalescent stages of infection, which are unavailable at early diagnosis. Nested PCR and real-time PCR require equipment. In this study, we developed a Loop-Mediated Iso...
Pusterla N, Gebhart CJ.Equine proliferative enteropathy (EPE) is a disease of foals caused by the obligate intracellular organism Lawsonia intracellularis. This emerging disease affects mainly weanling foals and causes fever, lethargy, peripheral oedema, diarrhoea, colic and weight loss. The diagnosis of EPE may be challenging and relies on the presence of hypoproteinaemia, thickening of segments of the small intestinal wall observed upon abdominal ultrasonography, positive serology and molecular detection of L. intracellularis in faeces. Although the clinical entity, diagnostic approach and treatment of EPE are w...
Stratford CH, Lester HE, Pickles KJ, McGorum BC, Matthews JB.Cyathostomins comprise 50 helminth species, considered the most problematic equine endoparasites. Three classes of anthelmintic are currently licensed for their control, namely the benzimidazoles (fenbendazole), tetrahydropyrimidines (pyrantel) and macrocyclic lactones (ivermectin and moxidectin). Anthelmintic resistance in cyathostomins is common. With no new classes expected in the near future, it is essential to determine the efficacy of the available anthelmintics to inform future control programmes. Objective: To determine the efficacy of all 3 anthelmintic classes against strongyles in e...
Boyen F, Smet A, Hermans K, Butaye P, Martens A, Martel A, Haesebrouck F.The use of β-lactam antibiotics results in the selection of bacteria showing resistance toward this class of antibiotics. The review focuses on the increasing importance of methicillin resistant staphylococci and broad-spectrum β-lactamase-producing Enterobacteriaceae in horses. Diagnostic protocols that optimize accurate identification of these bacteria from both clinical samples and samples obtained from putative carrier animals are described. In addition, the opportunities and pitfalls for preventive and curative measures are discussed.

Conventional T2 maps and gradient-echo images were obtained for com...
Tamin A, Rota PA.Hendra virus (HeV) and Nipah virus (NiV) are the causative agents of emerging transboundary animal disease in pigs and horses. They also cause fatal disease in humans. NiV has a case fatality rate of 40 - 100%. In the initial NiV outbreak in Malaysia in 1999, about 1.1 million pigs had to be culled. The economic impact was estimated to be approximately US$450 million. Worldwide, HeV has caused more than 60 deaths in horses with 7 human cases and 4 deaths. Since the initial outbreak, HeV spillovers from Pteropus bats to horses and humans continue. This article presents a brief review on the cur...
Moreno SA, Concepción JL, Nava M, Molinari J.In Venezuela, horses are indispensable for extensive cattle raising, and extensive cattle raising prevails in all regions. This determines the numerical relationship between horses and cattle (r = 0.93) to be relatively constant nationwide. At regional level, the average extension of cattle ranches varies greatly. However, in relation to the area covered by pastures, the numbers of horses (r = 0.95) and cattle (r = 0.93) are relatively uniform nationwide. Water buffalo occupy small fractions of the territory; therefore, their numbers are related to the area of pastures less strongl...

Results: All values are expressed as ...
Morlière P, Mazière JC, Patterson LK, Conte MA, Dupas JL, Ducroix JP, Filipe P, Santus R.Ferritin (Ft) impairment through (•)O2(-), H2O2, and (•)OH production occurs in the cases of ketoses, diabetes mellitus, acute intermittent porphyria and tyrosinemia. In addition to (•)Trp and TyrO(•) radical production, ferrous iron liberation and Ft synthesis stimulation, site-specific oxidation reactions are induced leading to toxic iron accumulation in organs with high Ft content, for example, liver and brain. To elucidate the potential pathways to Ft recovery, repair of oxidative damage to horse spleen apoferritin (apoFt) and Ft by quercetin (QH) or rutin (RH) was studied in the p...

van Weeren PR, Jeffcott LB.Twenty years ago a supplement of Equine Veterinary Journal was devoted to equine osteochondrosis (OC) and recognised the importance of this developmental disease to the equine industry. In the accompanying editorial several controversial issues were identified and a number of areas for further research were highlighted. Today, equine OC is still a major clinical problem, but the on-going research has resulted in much improved knowledge and understanding of this highly complicated disease. There is still conflicting evidence on the prevalence of OC due to the dynamic character of the condition,...
Flanagan KL, Morton JM, Sandeman RM.The aims of the present study were to identify the common gastrointestinal nematodes, to assess the prevalence of infestation with gastrointestinal nematodes, and to assess some potential indirect determinants of nematode parasitism in Victorian Pony Club horses. Methods: A total of 106 horses from five Pony Clubs from outer Melbourne and Geelong, Victoria, Australia, were enrolled in a cross-sectional study. Fresh faecal samples were collected and faecal egg counts (FECs) performed on site within 2 h of collection. Potential determinants of the FEC were analysed using logistic and negative bi...
Röcken M, Mosel G, Barske K, Witte TS.To describe successful repair of a diaphragmatic hernia in a standing sedated horse using a minimally invasive thoracoscopic technique. Methods: Clinical report. Methods: Warmblood mare with a diaphragmatic hernia. Results: An 18-year-old Warmblood mare with severe colic was referred for surgical treatment of small intestinal strangulation in a diaphragmatic defect. Twelve days after initial conventional colic surgery, left-sided laparoscopy in the standing sedated mare for diaphragmatic herniorrhaphy failed because the spleen obscured the hernia. One week later, a left-sided thoracoscopy was ...
Rubio-Martínez LM, Carstens A.Increased intraosseous pressure (IOP) is a well-characterized source of pain in humans that can be successfully treated by medullary decompression. This report describes the clinical and diagnostic findings, treatment and successful outcome of a horse with a four week long, non-weight bearing lameness secondary to suspected traumatically-induced increased IOP in the left radius. Scintigraphic examination characterized by severe increase in radiopharmaceutical uptake within the affected radius aided in the initial localization of the source of lameness. Decompression of the affected radius was ...
Penrod LV, Allen RE, Rhoads ML, Limesand SW, Arns MJ.Uterine inflammation results in a poor uterine environment and early embryonic loss in the mare due to an inhibition of maternal recognition of pregnancy caused from increased prostaglandin F2α (PGF2α). Oxytocin binds to endometrial cell receptors to activate prostaglandin synthesis. An oxytocin receptor antagonist (Atosiban) and a cyclooxygenase inhibitor (indomethacin) both decrease PGF2α production. The aim of this study was to evaluate the in vitro effects of Atosiban and indomethacin on equine uterine prostaglandin secretion. Equine endometrial explants were harvested on day two of beh...
Janssen IJ, Krücken J, Demeler J, Basiaga M, Kornaś S, von Samson-Himmelstjerna G.Macrocyclic lactones (MLs) represent the major drug class for control of parasitic infections in humans and animals. However, recently reports of treatment failures became more frequent. In addition to human and ruminant parasitic nematodes this also is the case for the horse-nematode Parascaris equorum. Nevertheless, to date the molecular basis of ML resistance is still not understood. Unspecific resistance mechanisms involving transporters such as P-glycoproteins (Pgps) are expected to contribute to ML resistance in nematodes. Here, complete sequences of two P. equorum Pgps were cloned and i...
Rendle DI, Rutledge F, Hughes KJ, Heller J, Durham AE.Metformin is a potential therapeutic agent for the treatment of insulin resistance (IR). In laboratory animals, orally administered metformin reduces intestinal glucose absorption and may therefore affect insulinaemic responses to oral carbohydrate ingestion. Objective: To determine whether pretreatment with metformin reduces plasma glucose concentration and insulin responses following consumption of dextrose in horses. Methods: Therapeutic cross-over study. Methods: Seven healthy Standardbred and Thoroughbred geldings were subjected to an oral dextrose challenge test on 4 occasions: with and ...
Anderson JL, Sloss BL, Meece JK.Several studies have shown that Blastomyces dermatitidis, the etiologic agent of blastomycosis, is a genetically diverse pathogen. Blastomycosis is a significant health issue in humans and other mammals. Veterinary and human isolates matched with epidemiological case data from the same geographic area and time period were used to determine: (i) if differences in genetic diversity and structure exist between clinical veterinary and human isolates of B. dermatitidis and (ii) if comparable epidemiologic features differ among veterinary and human blastomycosis cases. Results: Genetic typing of 301...
Oguma K, Ishida M, Maeda K, Sentsui H.Equine cells are required for isolation of viruses that infect the horse. However, only a few equine cell lines and cell cultures are available so far. Fetal horse kidney (FHK)-Tcl3.1 cell is a novel cell line established by introducing simian virus 40 (SV40) large T antigen. In the present study, the ability to propagate equine viruses was compared between FHK-Tcl3.1 cells and other equine cells. FHK-Tcl3.1 cells efficiently increased many viruses derived from or having pathogenicity to horses and produced high infective titers in culture fluids. These results indicate that FHK-Tcl3.1 cells w...
Kumar R, Kumar S, Khurana SK, Yadav SC.The importance of Trypanosoma evansi as the etiological agent for surra is often overlooked due to difficulty in accurate diagnosis of the disease. In the present study, an antibody-ELISA was developed using whole cell lysate antigen prepared from purified trypanosomes and used for seroprevalence study of T. evansi in equids. A total of 3695 equids were surveyed and blood samples were collected from each animal during September 2009 to August 2011. Out of these, 420 serum samples were found positive for presence of antibodies against T. evansi collected from equids of six agro-climatic zones o...
Lange-Consiglio A, Tassan S, Corradetti B, Meucci A, Perego R, Bizzaro D, Cremonesi F.This is the first study to compare the treatment of horse tendon and ligament injuries with the use of mesenchymal stromal cells (MSCs) obtained from two different sources: amniotic membrane (AMSCs) and bone marrow (BM-MSCs). The objective was to prove the ability of AMSCs to exert beneficial effects in vivo. Methods: Five million allogeneic frozen-thawed AMSCs or autologous fresh BM-MSCs were injected intralesionally in horses belonging to group A (51 horses) and group B (44 horses). The interval lesion/implantation was of 6-15 days for the AMSCs and 16-35 days for the BM-MSCs. Healing was as...
McCarty SM, Percival SL, Clegg PD, Cochrane CA.This study outlines the potential of a novel therapeutic dressing for the management of chronic wounds. The dressing incorporates polyphosphate, a non toxic compound with a number of beneficial characteristics in terms of wound healing, in a foam matrix. The aim of this study was to identify the potential of polyphosphate incorporated in the foam dressing to sequester the activity of matrix metalloproteinases (MMPs) and proteases derived from Pseudomonas aeruginosa. Methods used included gelatin zymography and milk-casein agar plate analysis. Results have shown that this dressing is effectivel...
Jahrling PB, Beall JL.Hydroxylapatite column chromatography methods were developed to characterize selected alphavirus populations. Different conditions of pH and phosphate molarity were required to obtain satisfactory elution profiles and separations for Western equine encephalomyelitis virus strains, compared with Eastern equine encephalomyelitis virus and Semliki Forest virus strains. Raising the pH of the buffers effected earlier elutions of all viruses. Selection of phosphate gradients with more gentle slopes and adjustment to the proper pH effected better separations of virus subpopulations. Elution profiles ...
Srihongse S, Grayson MA, Morris CD, Deibel R, Duncan CS.An extensive outbreak of eastern equine encephalomyelitis (EEE) occurred in upstate New York during the summer of 1976, with 37 cases confirmed in horses by isolation of virus and/or by serologic examination. Other specimens collected in the affected area yielded 16 further isolates: 9 from 818 pools of 33,365 mosquitoes, 5 from tissues of 64 birds and 2 from 4 sentinel pheasants with serologic conversions. EEE antibodies were also detected in 81 of 499 wild birds tested. Our data implicate sparrows, cowbirds, and catbirds in the amplification of EEE virus and Culiseta melanura mosquitoes as v...
Caol S, Divers T, Crisman M, Chang YF.Lyme disease in humans is predominantly treated with tetracycline, macrolides or beta lactam antibiotics that have low minimum inhibitory concentrations (MIC) against Borrelia burgdorferi. Horses with Lyme disease may require long-term treatment making frequent intravenous or intramuscular treatment difficult and when administered orally those drugs may have either a high incidence of side effects or have poor bioavailability. The aim of the present study was to determine the in vitro susceptibility of three B. burgdorferi isolates to three antibiotics of different classes that are commonly us...

Glorieux S, Vandekerckhove AP, Goris N, Yang XY, Steukers L, Van de Walle GR, Croubels S, Neyts J, Nauwynck HJ.Equine herpesvirus 1 (EHV1) is a ubiquitous equine alphaherpesvirus that causes respiratory disease, neurological symptoms and abortions. Current vaccines are not fully protective and effective therapeutics are lacking. A-5021 [(1'S,2'R)-9-[[1',2'-bis(hydroxymethyl)cycloprop-1'-yl]methyl]guanine], previously shown to possess potent anti-herpetic activity against most human herpesviruses, was evaluated for its potential to inhibit EHV1 replication. In equine embryonic lung (EEL) cells, infected with either a non-neurovirulent (97P70) or a neurovirulent (03P37) EHV1 isolate, A-5021 proved to be ...
Hillyer LL, Jackson AP, Quinn GC, Day MJ.Epidermal (infundibular) and dermoid cysts are unusual in the horse in contrast with other species. The diagnosis and treatment of six lesions in the dorsal midline of a three-year-old Thoroughbred-cross gelding is described. The lesions were believed to be congenital and presented asymptomatically but required attention because five of them were in the saddle region, thus preventing ridden exercise. Under general anaesthesia, the cysts were excised and subsequently examined histologically. The horse recovered uneventfully. This report is novel in that such midline cysts have not previously be...
Shearer TR, Holcombe SJ, Valberg SJ.To review the veterinary literature regarding healing and complications associated with equine celiotomy including anatomy and physiology, risk factors for incisional infection and hernia, and treatment. Background: Celiotomy is the most common approach to treat horses with surgical colic. Incision through the linea alba provides exposure to most of the abdomen for exploration, exteriorization, and correction of surgical lesions. Incisional apposition relies on suture strength during anesthetic recovery and for the first 30 days postoperatively. Factors associated with the patient, surgical le...
Kopper JJ, Bolger ME, Kogan CJ, Schott HC.Obtaining commercial fluids for intravenous administration (IVF) was challenging during a recent shortage. This necessitated use of custom-made non-sterile fluids for intravenous administration (JUGs) in some hospitals. There are no studies comparing outcome of horses treated with JUG versus IVF and limited information is available about adverse effects of JUGs. Objective: To evaluate death, complications, blood pH, and plasma electrolyte concentrations of horses that received JUG versus IVFs. Methods: One hundred eighty-six horses that received IVFs and 37 that received JUGs. Methods: A retro...

Animals Studied Eleven clinically healthy horses. Procedures IOP was measured bilaterally twice daily, at 8 AM and 4 PM, for 5 days. No medication was applied for the first 2 days of the study. Thereafter, one eye of each horse was treated with 0.1 mL of topical 1% atropine sulfate ointment twice daily (7 AM and 7 PM) for 3 days. The contralateral eye served as a control. In eight of the horses, an additional IOP reading was taken 3 days following cessation ...
Hussein H, Dulin J, Smanik L, Drost WT, Russell D, Wellman M, Bertone A.Our investigations evaluated the effect of VEL-0230, a highly specific irreversible inhibitor of cathepsin K (CatK). The objectives of our study were to determine whether repeated dosing of a CatK inhibitor (CatKI) produced a desired inhibition of the bone resorption biomarker (CTX-1), and document the effect of repeated dosing on bone homeostasis, structure, and dynamics of bone resorption and formation in horses. Twelve young exercising horses were randomized in a prospective, controlled clinical trial and received 4 weekly doses of a CatKI or vehicle. Baseline and poststudy nuclear scintigr...
Oliver-Espinosa O.Chronic diarrhea in the horse is defined as diarrhea present for more than several days with little if any improvement. The diagnosis and treatment of horses with chronic diarrhea usually present a great challenge to the clinician. There are many limitations to treatment of these patients given the limited numbers in which a final diagnosis can be achieved. The lack of knowledge of the alterations of horse microbiota during chronic diarrhea and the multiplicity of causes also make treatment challenging. A poor prognosis is often attached to chronic diarrhea, particularly in cases with neoplasi...
Kendall A, Bröjer J, Karlstam E, Pringle J.Mycotic rhinitis is an uncommon disease in horses with a wide range of clinical signs and treatment options based on case studies of a single or only a few individuals. Moreover, while dogs with mycotic rhinitis appear to respond well to treatment with topical enilconazole, this approach has yet to be reported in horses. Objective: The aim of this study was to describe the clinical findings, results of diagnostic investigations, treatment, and outcome in horses with mycotic rhinitis treated with topical enilconazole. Methods: Eight horses were included in the study. Methods: Medical records fr...
