Postsurgical segmental mesenteric ischemic thrombosis in a horse. A 16-year-old, Lusitanian stallion was admitted to the Veterinary Teaching Hospital with a 12-hour history of signs of abdominal pain. Exploratory celiotomy was performed due to an inguinal hernia, and a second celiotomy was performed in response to the abdominal pain. The horse was euthanized and mesenteric venous thrombosis was diagnosed and considered likely due to peritonitis and systemic inflammatory response syndrome (SIRS). Un étalon Lusitanien âgé de 16 ans a été admis à l’hôpital d’enseignement vétérinaire avec une anamnèse de 12 heures de douleurs abdominales. Une coel...
Differential expression of three members of the multidomain adhesion CCp family in Babesia bigemina, Babesia bovis and Theileria equi. Members of the CCp protein family have been previously described to be expressed on gametocytes of apicomplexan Plasmodium parasites. Knocking out Plasmodium CCp genes blocks the development of the parasite in the mosquito vector, making the CCp proteins potential targets for the development of a transmission-blocking vaccine. Apicomplexans Babesia bovis and Babesia bigemina are the causative agents of bovine babesiosis, and apicomplexan Theileria equi causes equine piroplasmosis. Bovine babesiosis and equine piroplasmosis are the most economically important parasite diseases that affect world...
Jugular thrombophlebitis in horses: a review of fibrinolysis, thrombus formation, and clinical management. Thrombophlebitis of the jugular vein is commonly observed in horses, particularly during intensive care, and leads to local and systemic inflammatory responses as well as head and neck circulatory impairment. Thrombolytic therapy is widely used in human practice with the aim of thrombus dissolution and recanalization of the injured vessels. There are similarities between human and horse coagulation and fibrinolytic processes. This review examines the fibrinolytic system, thrombus formation, and the clinical management of jugular thrombophlebitis, including thrombolytic therapy. There is eviden...

Expression of reference genes and T helper 17 associated cytokine genes in the equine intestinal tract. There is accumulating evidence for the involvement of pro-inflammatory cytokines associated with a T helper 17 response in intestinal disorders such as inflammatory bowel disease (IBD) in humans. The involvement of interleukin (IL)-17 or IL-23 in equine IBD has not been studied and most gene expression studies in the equine intestine have been limited to the use of a single non-validated reference gene. In this study, expression of the reference gene candidates β2 microglobulin (β2M), glyceraldehyde 3-phosphate dehydrogenase (GAPDH), histone H2A type 1, hypoxanthine-guanine phosphoribosyltra...
Oral examination and charting: setting the basis for evidence-based medicine in the oral examination of equids. The oral examination is performed in equids to assess and monitor oral health status, provide diagnoses, and determine efficacy of treatments. While there is currently insufficient scientific material of adequate quality to enable evidence-based medicine in equine dentistry, this by no means negates the clinician's responsibility to provide oral health care in a scientific and ethical manner. To do so requires that the clinician be knowledgable and skilled in dentistry and general medicine, that each case upholds the principles of scientific method, and that data is gathered and appraised in a...
Incorporating oral photography and endoscopy into the equine dental examination. This article discusses the significant features and use of digital cameras, intraoral cameras, and oral endoscopes in equine dental practice. Although system features believed to be important have been listed, specific system recommendations have been omitted, since each veterinarian must individually determine the best system to meet practice clinical needs and budget. Veterinarians are encouraged to thoroughly research not only the camera/endoscope purchase but also the capabilities of the entire system, the compatibility of the system with different computer software programs, the reputatio...
Salmonella spp. fecal shedding detected by real-time PCR in competing endurance horses. Fecal shedding of Salmonella spp. was recently documented in 8% of endurance horses presented to equine referral centers for colic. Previous studies have documented fecal shedding of Salmonella spp. in as few as 0.8% of the general horse population, although horses with colic appear to be at higher risk. Fecal Salmonella spp. shedding before and after endurance horse competitions has not been evaluated. Fecal samples were collected from 204 horses during three separate 100 mile endurance competitions. Following incubation in selenite broth, 289 fecal samples were tested by real-time PCR analys...
Corneal cross-linking in 9 horses with ulcerative keratitis. Corneal ulcers are one of the most common eye problems in the horse and can cause varying degrees of visual impairment. Secondary infection and protease activity causing melting of the corneal stroma are always concerns in patients with corneal ulcers. Corneal collagen cross-linking (CXL), induced by illumination of the corneal stroma with ultraviolet light (UVA) after instillation of riboflavin (vitamin B2) eye drops, introduces crosslinks which stabilize melting corneas, and has been used to successfully treat infectious ulcerative keratitis in human patients. Therefore we decided to study i...

Eating disorders and equine therapy: a nurse’s perspective on connecting through the recovery process. Patients with eating disorders may have the most complex interdisciplinary treatment plans of any mental illness. Nurses need innovative evidence-based treatment interventions to assist their patients with eating disorders on their road to recovery. Although much has been written about equine-assisted psychotherapy (EAP) and equine-facilitated psychotherapy, the literature has not described a detailed session that can help nurses understand how this experiential treatment works and the impact it can have on the patient. A review of the literature on eating disorders and on the use of equine th...

The objective of this study was to evaluate factors associated with infestation by Amblyomma cajennense on horses in two microregions of the state of Rio de Janeiro. Horses on 62 farms in the municipalities of the Itaguaí and Serrana microregions were evaluated between January and May 2009. The animals were examined to determine the presence of ticks and infestation level. The animals' rearing and management were assessed on each farm property using an epidemiological questionnaire. Out of the 635 horses evaluated, 41.6% were infested with A. cajennense. It was observed that farms in low-alti...
Equine gammaherpesviruses: perfect parasites? The evolutionary success of the equine gammaherpesviruses (GHVs) is demonstrated by their consistent and widespread presence in horse populations worldwide. Equine GHVs establish infection in young foals and can be continually detected over the lifetime of the host either by recrudescence of latent infections or by re-infection. A definitive diagnosis of clinical disease in horses due to GHV infection remains challenging given the ubiquitous nature of the GHVs in horses without clinical signs, as well as in horses with clinical signs ranging from mild respiratory disease to severe equine multi...
