Veterinary medicine for horses encompasses the study and application of medical practices to diagnose, treat, and prevent diseases in equine species. This field involves a comprehensive understanding of equine anatomy, physiology, pathology, and pharmacology. Veterinary practitioners employ a range of diagnostic tools and therapeutic interventions to address health issues in horses, including lameness, gastrointestinal disorders, respiratory conditions, and infectious diseases. Preventative care, such as vaccination and deworming programs, is also a significant aspect of equine veterinary medicine. This page gathers peer-reviewed research studies and scholarly articles that explore various aspects of veterinary medicine as it pertains to horses, including advancements in diagnostic techniques, treatment protocols, and preventive health strategies.
Rötting AK, Freeman DE, Eurell JA, Constable PD, Wallig M.To evaluate the in vitro protective effects of acetylcysteine and response of resident mucosal eosinophils in oxidant-induced injury to tissues of right dorsal colon of horses. Methods: 9 adult horses. Methods: Gastrointestinal mucosa was damaged in vitro with 3 mM hypochlorous acid (HOCl), with and without prior exposure to 6mM acetylcysteine. Control tissues were not exposed to HOCl or acetylcysteine. Control and damaged tissues were incubated in Krebs-Ringer-bicarbonate solution and tissue resistance measured during 240 minutes. Tissue permeability to radiolabeled mannitol was also used to ...
Kydd JH, Wattrang E, Hannant D.In general, vaccines containing inactivated equine herpesvirus-1 (EHV-1) fail to prevent abortion in pregnant mares following infection with a virulent strain of EHV-1. We have tested the hypothesis that resistance to EHV-1-induced abortion in pregnant mares is associated with high frequencies of EHV-1 specific, major histocompatibility complex (MHC) class I-restricted, cytotoxic T lymphocytes (CTL) in the circulation. To test this theory, three groups of pregnant mares were assembled with varying backgrounds of infection or vaccination in an attempt to mimic the immune status of the general p...
de Blaauw JA, Rijkenhuizen AB, van Nieuwstadt RA, Grinwis GC, Back W.Two grey mares, a 12-year-old Arabian and a 13-year-old Lippizaner cross, were referred for chronic pelvic limb lameness and abduction of the limb during the non supporting phase of the stride. The clinical examination revealed melanomas under the tail and on the perineum, and oedema of the proximal lame limb. A mass in the pelvic area was detected on rectal palpation. Laparoscopy was performed and the provisional diagnosis of malignant melanoma was made. Histological examination of the biopsy taken under laparoscopic control from the mass in the pelvis confirmed the diagnosis of malignant mel...
Kenny DE, Dugan SJ, Knightly F, Baier J.A 11.5-yr-old female Przewalski's wild horse (Equus caballus przewalskii) presented for unilateral blepharitis and drainage from the left eye. The left cornea was not ulcerated, and intraocular evaluation was hampered by severe corneal edema. The left eye appeared to respond positively to treatment with anti-inflammatories and a topical mydriatic agent. During the ensuing 2 yr, there were minor episodes of epiphora from the left eye. The discharge then increased, and a luxated lens was noted during an examination by a veterinary ophthalmologist as part of the preshipment examination. Initially...
Studdert MJ, Hartley CA, Dynon K, Sandy JR, Slocombe RF, Charles JA, Milne ME, Clarke AF, El-Hage C.Five of 10 pregnant, lactating mares, each with a foal at foot, developed neurological disease. Three of them became recumbent, developed complications and were euthanased; of the two that survived, one aborted an equine herpesvirus type 1 (EHV-1)-positive fetus 68 days after the first signs were observed in the index case and the other gave birth to a healthy foal on day 283 but remained ataxic and incontinent. The diagnosis of EHV-1 myeloencephalitis was supported by postmortem findings, PCR identification of the virus and by serological tests with an EHV-1-specific ELISA. At the time of the...
Wasfi IA, Abdel Hadi AA, Elghazali M, Alkateeri NA, Hussain MM, Hamid AM.The pharmacokinetics of diphenhydramine (DPHM) was compared in camels (n = 8) and horses (n = 6) following intravenous (i.v.) administration of a dose of 0.625 mg/kg body weight. In addition, the metabolism and urinary detection time of DPHM was evaluated in camels. The data obtained (median and range in brackets) in camels and horses, respectively, were as follows. The terminal elimination half lives (h) were 1.58 (1.13-2.58) and 6.11 (4.80-14.1), and the total body clearances (L/h per kg) were 1.42 (1.13-1.74) and 0.79 (0.66-0.90). The volumes of distribution at steady state (L/kg) were 2.38...
Baccam P, Thompson RJ, Li Y, Sparks WO, Belshan M, Dorman KS, Wannemuehler Y, Oaks JL, Cornette JL, Carpenter S.Lentiviruses exist in vivo as a population of related, nonidentical genotypes, commonly referred to as quasispecies. The quasispecies structure is characteristic of complex adaptive systems and contributes to the high rate of evolution in lentiviruses that confounds efforts to develop effective vaccines and antiviral therapies. Here, we describe analyses of genetic data from longitudinal studies of genetic variation in a lentivirus regulatory protein, Rev, over the course of disease in ponies experimentally infected with equine infectious anemia virus. As observed with other lentivirus data, t...
Dabareiner RM, Carter GK.In conclusion, horses with heel or navicular area pain vary, and no one treatment option is suitable for all horses. Each horse must be evaluated individually to determine which structure in the palmar aspect of the foot is injured, severity of disease, horse and hoof conformation, and horse use and level of performance expectation before a treatment plan can be developed. Overall, there are many treatment options to help these horses to perform their intended athletic event.
Dyson S, Marks D.New information about foot anatomy, effects of local analgesia, and advances in diagnostic imaging (ultrasonography, nuclear scintigraphy, MRI, CT, and endoscopy) has opened the way for more specific diagnoses of lameness. New questions have been raised, however, and some older ideas are now in doubt. This article discusses some of these findings in the light of our own clinical experiences as they relate to diagnosis of the causes of foot pain.
O'Grady SE, Poupard DA.Adherence to the basic principles of physiologic horseshoeing is essential to maintaining hoof health and soundness. Most horses do not require special trimming or shoeing techniques. Becoming familiar with a few basic concepts can help the veterinarian to recognize when changes in trimming or shoeing might be expected to help the performance of a sound horse or might help to restore the performance of one that is lame. Sound physiologic horseshoeing can only be achieved by a thorough knowledge of, strict adherence to, and skillful application of basic principles, such as hoof angle, HPA, and ...
Redden RF.Understanding the basic mechanisms of hoof capsule distortion enables the clinician to unravel the sometimes complex mix of abnormalities, identify early warning signs, and manage existing problems more effectively. Distortion of the hoof capsule can often seem like a complicated puzzle by the time the veterinarian is called to examine the lame horse. Evaluating each of the components of the hoof capsule, both individually and as an integrated unit, allows the clinician to tease apart the tangle of primary and secondary problems and come up with effective options for countering or attenuating ...
Fischer L, Minke J, Dufay N, Baudu P, Audonnet JC.In order for DNA vaccines to become a practical alternative to conventional vaccines their ability to induce antibody responses in large mammals needs to be improved. We used DNA vaccination against rabies in the horse as a model to test the potential of two different strategies to enhance antibody responses in a large mammalian species. The administration of the DNA vaccine in the presence of aluminum phosphate improved both the onset and the intensity of serological responses but was not potent enough to achieve seroconversion in all vaccinated ponies. However, when the DNA vaccine was formu...
Parks A.The list of possible diagnoses derived from matching anatomic structures or tissues to pathologic processes is inevitably broad in nature. Understanding and observation of distal limb function, conformation, and balance is the basis of identifying where the greatest abnormal stresses within the distal limb are likely to occur. This is key to focusing the diagnostic process and, in some instances, to treating the horse when a definitive diagnosis cannot be achieved.
Greet TR, Curtis SJ.Foot management and hoof care of foals, weanlings, and yearlings tends to be considered a specialist job. Many farriers and veterinary surgeons have little exposure to young and growing stock. Nevertheless, a variety of angular and flexural limb deformities can benefit from simple podiatry techniques, which can be performed provided that a few basic rules are followed. The combined skills of the farrier and veterinary surgeon offer many young horses with angular or flexural limb deformities a chance of a future athletic career.
Parks A, O'Grady SE.Laminitis is divided into four different phases: developmental, acute, subacute, and chronic. The focus of this article is on treating the laminitic horse after the cessation of therapy for the acute phase, that is, usually 2 to 4 weeks after the onset of clinical signs.
Ovnicek GD, Page BT, Trotter GW.The principles and techniques of natural balance trimming and shoeing are designed to optimize the efficiency and function of the foot. The basic guidelines have evolved in part from wild horse hoof imprint studies done in 1986 through 1987 and first presented in 1995. Further research has contributed to these principles and guidelines to make them applicable to domestic horses.
Redden RF.Radiographic examination of the equine foot can provide the veterinarian and farrier with a wealth of information. Positioning and selection of exposure factors are of central importance if one is to produce radiographs of maximum diagnostic value.
Moyer W.Hoof wall defects in horses are common occurrences, and, fortunately, many of those detected present little or no danger to the individual horse. Those defects that are either presently a problem or have a great likelihood of being a problem do often require specialized consideration. Horse shoeing and farriery are ancient practices; over the years, a multitude of methods, theories, and management schemes have been proposed. It is unfortunate to note that few studies are available to provide an accurate incidence rate, a better understanding of the various causes, and, lastly, a comparative ap...
Honnas CM, Dabareiner RM, McCauley BH.Because of the hoof capsule, surgery of the equine foot is often perceived to be quite difficult. Knowledge of the specific disease entities that require surgical intervention as well as an in-depth understanding of the anatomy of the tissues beneath the hoof capsule is a definite prerequisite to successful surgical treatment. This article details the surgical approaches used to treat septic navicular bursitis, septic pedal osteitis, infection of the collateral cartilages, and keratomas. The principles used to treat these conditions can be applied to a variety of other conditions for which acc...
Merriam JG.There is a lot of room for us to become the central source of medical information regarding shoeing and lameness in our own practice area. This takes a good bit of effort and a real "outreach" to client and farrier. It can be done with the one tool we are best at--the acquisition and careful dispensing of information that we can put together regarding the health of the foot. Such information includes the following: 1. Radiographically guided hoof trimming and shoeing. 2. Ultrasonography. 3. Digital radiography. 4. Thermography. 5. Nutritional and health counseling. Become the "local" expert in...
Cheramie HS, O'Ggrady SE.There are many different commercially available hoof repair/adhesive products. The application of these products in the treatment of various foot conditions is continuing to evolve based on sound medical and farriery principles as well as imagination. Successful application of these products depends largely on using proper hoof wall preparation and adhesive application techniques. Success also depends on a realistic expectation of the final outcome when accounting for the physical limitations of the adhesive products and the underlying hoof problem. Our results with these techniques have been ...
Turner TA.The examination of the foot must be based on observations of the hoof, followed by a careful determination of areas of pain. This must be followed by an assessment of the biomechanical forces on the hoof and limb. Finally, imaging gives insight into the nature of the injury and allows the examiner to prognosticate the outcome.
Kohler AK, Stone DM, Hines MT, Byrne BA, Alperin DC, Norton LK, Hines SA.Rhodococcus equi is an opportunistic pathogen in immunocompromised humans and an important primary pathogen in young horses. Although R. equi infection can produce life-threatening pyogranulomatous pneumonia, most foals develop a protective immune response that lasts throughout life. The antigen targets of this protective response are currently unknown; however, Mycobacterium tuberculosis is a closely related intracellular pathogen and provides a model system. Based on previous studies of M. tuberculosis protective antigens released into culture filtrate supernatant (CFS), a bacterial growth s...
Faber MJ, van Weeren PR, Schepers M, Barneveld A.In order to objectively quantify the effect of manipulation on back-related locomotion anomalies in the horse, a recently developed kinematic measuring technique for the objective quantification of thoracolumbar motion in the horse was applied in a dressage horse that was suffering from a back problem. In this horse, clinically, a right-convex bending (scoliosis) from the 10th thoracic vertebra to the second lumbar vertebra was diagnosed. As a result, there was a marked asymmetric movement of the thoracolumbar spine. Functionally, there was severe loss of performance. Thoracolumbar motion was ...
Théon AP, Pascoe JR, Galuppo LD, Fisher PE, Griffey SM, Madigan JE.To determine the benefits of reducing the interval between surgical cytoreduction and intratumoral administration of cisplatin. Methods: Randomized clinical study. Methods: 70 horses with 89 incompletely resected T2- and T3-stage sarcoids (n = 64) and squamous cell carcinomas (25). Methods: Horses were given 4 intratumoral treatments of cisplatin at 2-week intervals. The first treatment was given at the time of, or immediately after, surgical resection for horses treated in accordance with the perioperative protocol (group 1). Horses in group 2 were treated with cisplatin after the skin healed...
Judy CE, Chaffin MK, Cohen ND.To identify features of guttural pouch (auditory tube diverticulum) empyema in horses and compare findings of uncomplicated guttural pouch empyema with guttural pouch empyema complicated by chondroids. Methods: Retrospective study. Methods: 91 horses with guttural pouch empyema. Methods: Medical records of horses with guttural pouch empyema were reviewed. Results: The most common owner complaint and abnormal finding was persistent nasal discharge. Chondroids were detected in 21% (19/91) of affected horses. Streptococcus equi was isolated from the guttural pouch in 14 of 44 horses; for Streptoc...
Firth EC, Greydanus Y.The talus and proximal and distal epiphysis of the humerus, radius, femur, tibia and distal metacarpus of 20 foals aged 0 to 150 days were obtained at necropsy and sawn sagittally into slabs 4 to 8 mm thick. The thickness of the cartilage (articular cartilage and unossified epiphyseal cartilage) was measured in three to five places in each slab, using a sliding calliper. In most epiphyses, the site, or sites, of thickest cartilage was constant in all foals examined. The difference between thickest and thinnest cartilage within one epiphysis was greatest in distal femora and least in distal met...
Baird AN, Cohen ND, Taylor TS, Watkins JP, Schumacher J.During a 5-year period, renosplenic entrapment of the large colon was diagnosed in 57 horses referred to the Texas Veterinary Medical Center. The signalment of and clinical signs of disease in these horses were compared with such variables in 200 horses referred for other types of colic. Findings did not support a male gender predilection for this disease, as was previously reported. The case survival rate was 93% for this group of horses. Fourteen of the horses were treated nonsurgically by rolling them clockwise while they were under general anesthesia. Data supported the safety and efficacy...
Berhane Y, Elliott J, Bailey SR.Haemodynamic disturbances leading to ischaemia and reperfusion injury of the digit are thought to be involved in the pathophysiology of acute equine laminitis. Identification of physiological regulators of blood flow through the equine digit is important in identifying factors, which may predispose animals to laminitis. A method was developed to assess endothelium-dependent responses of the isolated Krebs-perfused equine digit by co-administration of 5-hydroxytryptamine (5-HT) with vasodilator agents, carbachol (CCh), bradykinin (BK) and substance P (SP). Bolus co-administration of CCh (0.02-2...
Machado M, Wilson TM, Ribeiro de Sousa DE, Lopes Câmara AC, Furlan FH, Silva Almeida E Macêdo JT, Pupin RC, Amaral de Lemos RA, Armién AG....Snake bite envenomations in farm animals are generally overestimated as the cause of mortality in rural areas in Latin America. However, most cases are based only on anecdotal information and assumptions, and lack diagnostic evidence. There are few proven reports of envenomation and death in horses caused by snakebites from members of the Bothrops genus (lancehead pit vipers). This study presents epidemiological and clinical-pathological findings of fatal bothropic envenomation in horses from Central Western Brazil in order to contribute to the correct diagnosis of this condition. A survey of ...
McPherson EA, Lawson GH, Murphy JR, Nicholson JM, Breeze RG, Pirie HM.Breed, age, weight, type of work performed, seasonal onset, poor ventilation and exposure to moulds in the habitat were investigated in relation to the occurrence of chronic obstructive pulmonary disease (COPD). COPD was most commonly detected in showjumping and hacking horses. The older a horse, the more likely it was to become affected although most were 6 to 10 years of age. Of the horses in this sample of the population, which was not a random one, thoroughbred horses were affected least and ponies most often. The high incidence in ponies was related to their more frequent exposure to poor...
Leonida A, Todeschini G, Lomartire G, Cinci L, Pieri L.To histologically assess the effectiveness of a socket-preservation technique using enzyme-treated equine bone granules as a bone-graft material in combination with an equine collagen matrix as a scaffold for soft-tissue regeneration. Background: Enzyme-treated equine bone granules and equine collagen matrix recently have been developed to help overcome alveolar bone deficiencies that develop in the wake of edentulism. Methods: The patient had one mandibular molar extracted and the socket grafted with equine bone granules. The graft was covered with the equine collagen matrix, placed in a doub...
Bowling AT, Byrns G, Spier S.The pedigree origin of a base pair substitution in the horse muscle sodium channel gene that confers susceptibility to the muscle disease hyperkalemic periodic paralysis (HYPP) was investigated with a set of 978 Quarter Horses. The horses were chosen at random, based on a collection of blood samples taken between 1989 and 1991 to meet parentage testing requirements, primarily but not exclusively from breeding stallions. The frequency of Quarter Horses positive for the base pair substitution, all heterozygotes, was 4.4%, which corresponds to an allelic frequency of 0.02. All horses positive for...
Leise BS, Fugler LA, Stokes AM, Eades SC, Moore RM.To determine the magnitude and duration of effects of acepromazine administered intramuscularly (IM) on digital and systemic hemodynamic variables in clinically healthy horses. Methods: Experimental study. Methods: Healthy adult horses (n=12). Methods- An ultrasonic Doppler flow probe was surgically implanted around the medial palmar digital artery before the study. Catheters were inserted in the transverse facial artery, lateral palmar digital artery, and jugular vein. A treatment group (n=6) was administered 0.04 mg/kg body weight of acepromazine IM; control horses (n=6) were administered an...
Bowling AT, Gordon L, Penedo MC, Wictum E, Beebout J.We describe a method for agarose IEF under acid conditions in which a single gel can be used to diagnose from equine red cell lysates genetic variants for carbonic anhydrase (CA) and catalase (Cat). Family and population data for 4801 horses of 27 breeds and seven trap sites of Great Basin feral horses are presented to support the presence of a sixth CA allele, CAE, which has been recognized previously, but not described by published data. Allelic frequencies for the two systems suggest it may be appropriate to use this gel for parentage verification programmes or to obtain population data for...
MacNicol JL, Pearson W. organ culture can provide insight into isolated mucosal responses to particular environmental stimuli. The objective of the present study was to investigate the impact of a prolonged culturing time as well as the addition of acidic gastric fluid into the environment of cultured gastric antral tissue to evaluate how altering the commonly used neutral environment impacted tissue. Furthermore, we aimed to investigate the impact of G's Formula, a dietary supplement for horses, on the secretion of gastrin, interleukin1-beta (IL-1β), and nitric oxide (NO). These biomarkers are of interest due to ...
Basher AW, Severin GA, Chavkin MJ, Frank AA.Three horses were examined because of exophthalmos and others signs indicative of a space-occupying orbital mass. In 2 horses, exenteration was used to remove the orbital mass. In a third horse, an orbital tumor and lung metastases were found at necropsy. Routine histologic and Grimelius' histochemical staining were used on fixed tissues; immunohistochemical staining for chromogranin and electron microscopy also were performed. Masses were orbital neuroendocrine tumors. Horses that underwent exenteration were alive 19 and 24 months after surgery. Hypotension was encountered at surgery in both ...
Leadon DP, Jeffery R, O'Toole D, Duggan V.This report compiles the available information on unwanted horses in Ireland for 2011 and 2012 and builds upon the previous report for the period 2005 to 2010. Similar trends are present in the high value responsible ownership category and the practicing veterinary profession although extensively involved in horse welfare, euthanises a small proportion of Ireland's unwanted horses. Welfare groups have limited resources and a limited ability to deal with such an extensive problem, which has involved very large numbers of horses. Local authorities continue to have to devote significant efforts a...
Tyrnenopoulou P, Fthenakis GC.Antibiotic administration is a standard therapeutic practice for the treatment of reproductive disorders of equids. This might lead to undesirable microbial imbalance and could favour the acquisition of antibiotic resistance. Therefore, it is imperative for clinicians to understand patterns of antibiotic resistance when considering and developing treatment regimes. Continued engagement of clinicians with novel alternative approaches to treat reproductive infections would be essential in order to address this rising threat within the One Health perspective. The objectives of the present review ...
Leendertse IP.A three year old warm-blood gelding with severe colic was referred to a veterinary clinic. The history revealed that the horse was found early in the morning with severe colic, and laying in the pasture. On arrival the clinical examination showed a complete wet horse with a pulse rate of 92/min, a respiratory rate of 24/min., a pcv of 0.50 L.L.-1, a T. of 38.0 degrees C, and no gastric reflux. Rectal examination revealed a sticky rectal mucous membrane and a colonic impaction together with displacement of the large colon. A diagnostic laparotomy showed an impaction as is seen in horses with Gr...
Riera FL, Roldán JE, Espinosa JM, Fernandez JE, Ortiz I, Hinrichs K.Embryo biopsy for fetal sexing has clinical application, but few reports are available of its use within an active embryo transfer program. We evaluated results on biopsy of 459 embryos over one breeding season. There were no significant differences in pregnancy rate between biopsied and non-biopsied embryos (72% vs 73%) or for biopsied embryos recovered at the centre (73%) compared with those shipped overnight (72%). However, the pregnancy rate decreased significantly in shipped embryos biopsied ≥20h after collection. Overall, 86% of biopsies provided a sex diagnosis. The likelihood of a po...
Tatarniuk DM, Hill JA, Modesto RB, Swor TM, Caston SS, Kersh KD.To report the outcome of horses used in western performance disciplines after deep branch lateral plantar neurectomy/fasciotomy surgery for hind limb proximal suspensory desmopathy (PSD). Methods: Retrospective analysis. Methods: Twenty-one client-owned horses. Methods: Medical records were reviewed (2009-2019) for horses involved in western performance disciplines that had been treated with deep branch lateral plantar neurectomy and plantar fasciotomy for lameness due to hind limb PSD. Follow-up was obtained by reexamination and/or verbal interviews with owners >2 years postoperatively. Res...
Rutllant J, Meyers SA.It is generally accepted that spermatozoa become functionally mature during epididymal transit. The objective of this study was to determine whether the cellular location of equine PH-20 is modified during epididymal transit and, if so, the mechanism for such modification. Sperm were isolated from caput and cauda epididymal regions from stallions undergoing castration (n = 7) and used as whole sperm cell or subjected to nitrogen cavitation for isolation of plasma membrane proteins. Both caput and cauda sperm and sperm protein extracts were subjected to N-deglycosylation, O-deglycosylation, or ...
Green SL, Conlon PD.The pharmacokinetics of amikacin, administered iv at 7 mg/kg, every 8 h, were evaluated over the first 48 h of hospitalisation in 7 critically ill hypoxic premature foals and compared with those in 8 full-term nonhypoxic critically ill neonatal foals. The pharmacokinetic data were used to calculate dosage schedules that would maintain the plasma amikacin concentrations in individual foals within a target range of > or = 15 micrograms/ml but < 30 micrograms/ml for peak values and < or = 3 micrograms/ml for trough values. The results indicated a statistically significant increase in the amikacin...
Rosanowski SM, MacEoin F, Graham RJTY, Riggs CM.Complications following open standing castration (OSC) in Thoroughbred racehorses are well recognised but variation in their prevalence and severity between populations is not well documented. Objective: To describe the prevalence and severity of complications in the 30 days following OSC. Methods: A retrospective cohort study of veterinary clinical records relating to horses that underwent OSC between July 2007 and July 2012. Methods: Complications were graded on a severity score from N, no complications, to C3, severe complications. Additional data were accessed for each horse including age,...
Harkins JD, Queiroz-Neto A, Mundy GD, West D, Tobin T.This report describes the development of a behaviour chamber and the validation of the chamber of measure locomotor activity of a horse. Locomotor activity was detected by four Mini-beam sensors and recorded on a data logger every 5 min for 22 h. Horses were more active during daytime than in the evening, which was at least partially related to human activity in their surroundings. To validate the ability of the chambers to detect changes in activity, fentanyl citrate and xylazine HCl, agents well-characterized as a stimulant and a depressant, respectively, were administered to five horses. Fe...
Meyer EE, Morris PG, Elcock LH, Weil J.Rabies was diagnosed in 2 adult Quarter Horses with hindlimb hyperesthesia and progressive weakness. Microscopic examination of the cord and brain of the first horse revealed nonsuppurative meningomyelitis and ganglioneuritis in the cord extending cranially to the 6th cervical segment. Fluorescent antibody test results of both horses were positive for rabies in hindlimb peripheral nerve specimens, but negative in sections of the upper lip. Salivary gland, cerebrum, cerebellum, hippocampus, musculocutaneous nerve, cornea, and optic nerve specimens were tested for rabies by fluorescent antibody ...
Wilks CR, Barton MD, Allison JF.Immune responses to Rhodococcus equi were assayed in mares and foals on 7 studs in south-eastern Australia using skin test reactivity to the intradermal injection of culture filtrate and an indirect fluorescent antibody test. The prevalence of positive skin-test reactions did not differ between studs with a history of R. equi disease and those without but there were more mares with high antibody titres on studs with a disease history. A leucocyte extract prepared from mares that were skin-test positive was evaluated for its ability to protect foals exposed to experimental or natural challenge:...
Dadaci M, Gundeslioğlu AO, Ince B, Altuntas Z.Total or subtotal amputation of the external ear related to horse bite is an uncommon situation. In our case, we report successful microsurgical revascularization of almost totally amputated ear of a 75-year-old male patient caused by a horse bite.
