Complications and survival in horses with surgically confirmed right dorsal displacement of the large colon. This study compared post-operative complications and survival in horses with right dorsal displacement of the large colon (RDD) and horses with other non-strangulating large colon (NSLC) lesions. Data were obtained from medical records of horses undergoing exploratory laparotomy from 2000 to 2016 and from owner questionnaire. Of 137 horses that fitted the inclusion criteria, 67 (49%) had RDD and 70 (51%) had NSLC lesions. Twenty-eight horses with RDD (42%) and 27 horses with NSLC (39%) experienced ≥ 1 complication after surgery. The RDD group showed more severe complications than the NSLC gr...
Inappropriate lactation in a 15-year-old thoroughbred mare. A 15-year-old thoroughbred non-pregnant mare was presented with ongoing inappropriate lactation. The most likely cause, equine Cushing's disease, was ruled out through biochemical testing. Milk cytology and bacterial culture showed no evidence of mastitis or neoplasia. Idiopathic inappropriate lactation was diagnosed and treatment with pergolide was recommended. Lactation inappropriée chez une jument Pur-sang âgée de 15 ans. Une jument Pur-sang non gravide âgée de 15 ans a été présentée avec une lactation continue inappropriée. La cause la plus probable, la maladie de Cushing, a étÃ...
Haematological profile in foals during the first year of life. Foals' haematological values change constantly during their first year of life. The use of updated age-based reference intervals (RIs) is imperative for providing accurate diagnosis and optimum care for sick foals. The authors' objective was to provide updated RIs for 13 haematological values in 2, 7, 14, 30, 90, 180 and 365-day-old foals and to investigate the changes over time in each measured value. Venous blood was collected at those ages from clinically healthy foals. Thirteen haematological values were analysed. The 95% RIs were reported using a bootstrapping method. Differences over tim...
Rhodococcus equi-specific hyperimmune plasma administration decreases faecal shedding of pathogenic R. equi in foals. is the most common cause of pneumonia in young foals. Pneumonic foals are an important source of environmental contamination as they shed higher amounts of in their faeces than unaffected foals. As -specific hyperimmune plasma (HIP) lessens clinical pneumonia, we hypothesise that its use would result in decreased faecal shedding of by foals. Neonatal foals were either given HIP (n=12) or nothing (n=9, control) shortly after birth and were then experimentally infected with Faeces were collected before and on weeks 2, 3, 5 and 7 after infection. Presence of virulent was tested using qPCR. T...
Plasticity of endometrial epithelial and stromal cells-A new approach towards the pathogenesis of equine endometrosis. Equine endometrosis, a frequent cause of subfertility, is characterized by periglandular fibrosis, and no treatment exists. Endometrial biopsies not only contain diseased glands, but also contain healthy glands and stroma. Myoepithelial (ME) and myofibroblastic (MF) markers are calponin, smooth muscle actin (SMA), desmin and glial fibrillary acidic protein (GFAP). Epithelial vimentin expression indicates epithelial to mesenchymal transition (EMT). The aim of this immunohistochemical study was to investigate whether biopsies with endometrosis express MF and ME markers and vimentin. Compared to ...

Adipose tissue dysfunction in obese horses with equine metabolic syndrome. Obesity is a common feature of equine metabolic syndrome (EMS). In other species, obese adipose tissue shows pathological features such as adipocyte hypertrophy, fibrosis, inflammation and impaired insulin signalling all of which contribute to whole body insulin dysregulation. Such adipose tissue dysfunction has not been investigated in horses. Objective: To determine if obese horses with EMS have adipose tissue dysfunction characterised by adipocyte hypertrophy, fibrosis, inflammation and altered insulin signalling. Methods: Cross-sectional post-mortem study. Methods: Samples of peri-renal (v...
The prevalence of elevated gamma-glutamyltransferase and sorbitol dehydrogenase activity in racing Thoroughbreds and their associations with viral infection. In racehorses, serum gamma-glutamyltransferase (GGT) activity is positively correlated with cumulative days in training and, when ≥100 IU/L, has been associated with poor performance. The prevalence of increased GGT activity in North American Thoroughbreds and its aetiopathogenesis are unknown. Four emerging viruses, pegivirus E (PgV E; equine pegivirus), hepacivirus A (HcV A; equine hepacivirus), pegivirus D (PgV D; Theiler's disease virus), and equine parvovirus-hepatitis (EqPV-H) have been identified in horses with clinical and subclinical hepatopathy. Available prevalence data indicate ...
Airborne particulate size and concentrations in five Thoroughbred training yards in Newmarket (UK). Despite their implication in the pathogenesis of lower airway inflammation, limited baseline data exists for airborne particulates in Thoroughbred racehorse stalls in the United Kingdom. This study documents airborne particulate size and concentrations in Newmarket training yards using a nephelometer (DustTrak DRX 8534, TSI). Each stall was sampled on a summer and winter day at three time points (morning, midday and evening). Minimum, mean and maximum/min ranges were calculated for the fraction of particulates with an aerodynamic diameter smaller than 2.5 μm (particulate matter (PM) 2.5) an...
The effect of climate, season, and treatment intensity on anthelmintic resistance in cyathostomins: A modelling exercise. Anthelmintic resistance is widespread in equine cyathostomin populations across the world, and with no new anthelmintic drug classes in the pharmaceutical pipeline, the equine industry is forced to abandon traditional parasite control regimens. Current recommendations aim at reducing treatment intensity and identifying high strongylid egg shedders in a targeted treatment approach. But, virtually nothing is known about the effectiveness of these recommendations, nor their applicability to different climatic regions, making it challenging to tailor sustainable recommendations for equine parasite...
Identification of macrolide- and rifampicin-resistant Rhodococcus equi in environmental samples from equine breeding farms in central Kentucky during 2018. Rhodococcus equi causes severe pneumonia in foals and is most often recognized in people as an opportunistic pathogen. Longitudinal studies examining antimicrobial-resistant R. equi from environmental samples are lacking. We hypothesized that antimicrobial-resistant R. equi would be detectable in the ground (pasture soil or stall bedding) and air at breeding farms with previous documentation of foals infected with resistant isolates, and that concentrations of resistant isolates would increase over time during the foaling season. In this prospective cohort study, ground and air samples were co...
Mycobacterium branderi Infection in a Horse with Granulomatous Mesenteric Lymphadenitis. Although relatively uncommon in horses, infections caused by Mycobacterium spp. may affect the gastrointestinal tract. Mycobacterium branderi is a non-tuberculous Mycobacterium (NTM) that causes respiratory infections in man. Non-tuberculous mycobacteria may also affect horses; however, infection by M. branderi has not yet been reported in this species. This report describes the clinical, pathological, microbiological and molecular findings of M. branderi infection in a horse, causing granulomatous mesenteric lymphadenitis. A 17-year-old Thoroughbred stallion had a 3-month history of chronic d...
Enterococcus infections in foals. Enterococci have been increasing in prevalence in foal sepsis over the past three decades. There are no published studies in the peer-reviewed literature documenting common sites of infection, antimicrobial susceptibility, or outcome specifically associated with enterococcal infections in foals. Our objectives were to evaluate the sites of origin, antimicrobial susceptibility, and survival outcome to discharge in foals with enterococcal infections compared with foals with sepsis of another bacterial etiology. Seventy-five foals 0-30 days of age with cultures positive for Enterococcus and 170 c...
The effect of insulin infusion on heart rate and systemic blood pressure in horses with equine metabolic syndrome. There is little evidence that horses with equine metabolic syndrome (EMS) have higher resting blood pressures than horses with normal insulin sensitivity. However, there are indications that EMS horses have an altered dynamic response to the cardiovascular effects of insulin. Objective: To examine heart rate and the systemic blood pressure response in EMS and control horses during insulin infusion. Methods: Cross-sectional study. Methods: Horses were examined with an oral sugar test (OST) and a euglycaemic hyperinsulinaemic clamp (EHC). Based on the results from the OST, the horses were classi...
