Fecal microbiota transplantation has been used empirically for decades in equine medicine but evidence based information on this technique is scarce. This in vitro study aimed to assess the effect of a common fecal pre-transplantation processing method on microbiota composition and viability of the fecal inoculum. A fresh equine fecal sample was divided in three 300g aliquots, to be processed identically as follows: feces (T ) were mixed with 1 L of lukewarm water and chopped using an immersion blender to obtain a mixture (T ), which was left uncovered during 30 minutes (T ) and filtered through a sieve to obtain a fecal infusion (T ). Samples were taken at different steps of the procedure (T ) and immediately stored at 4°C < 6 hours until processing. Bacterial 16S rDNA amplicon profiling associated to propidium-monoazide treatment was performed in each of the 12 samples to select living bacteria. Total flora was measured using quantitative PCR analysis. Bacterial community structure, composition and total flora were statistically compared (significance p < 0.05). No significant differences in ecological indices or abundance of the major bacterial genera were identified for the different steps of fecal processing. Estimated total flora (mean ± SD) in the final fecal infusion was not significantly lower (10.06 ± 0.07 log gene copies/g) than in the original manure (10.29 ± 0.3 log gene copies/g). Results were similar for all three fecal aliquots. These results suggest that the processing method described in this study is replicable and the resultant fecal inoculum contains live bacteria and a microbial population similar to the original fecal sample.

Lawsonia intracellularis (LI) is an obligate intracellular gram-negative rod causing equine proliferative enteropathy (EPE). Occasional cases of EPE have been reported in foals living in Belgium, but the seroprevalence of equine LI in this country is unknown. The target population included clinically healthy adult horses, whose blood samples were collected and analysed for specific IgG antibodies against LI using a blocking enzyme-linked immunosorbent assay (bELISA) test. Results were expressed as Percentage of Inhibition (PI). Samples that had a PI <20% were judged as negative, those between 20 and 30% as inconclusive and those >30% were considered positive. A total of 356 blood samples were analysed with 352 horses (98.8%) testing positive, 2 horses (0. 6%) testing negative and 2 horses (0.6%) showing inconclusive results. The large percentage of seropositive samples obtained in this study confirms a widespread exposure of Belgian horses to LI. [less ▲]

A 6-year-old halfbred gelding horse was referred for coughing, serious nasal discharge and epistaxis. Examinations revealed petechiae on the upper respiratory tract, acute pulmonary haemorrhage, slight haematuria and severe azotaemia. A diagnosis of equine herpesvirus type 1 infection with endotheliotropic strain D752 was confirmed by polymerase chain reaction (PCR) on whole blood and nasal swab. This atypical presentation is probably explained by the vascular tropism of the virus, which appears to be multisystemic, including respiratory and renal as seen in this case. [less ▲]

Les ulcères gastriques sont une affection très fréquente chez les équidés adultes mais aussi chez les poulains, et constituent la première maladie de l’estomac du cheval. Seuls les ulcères des équidés adultes seront présentés ici. Du fait de cette forte prévalence, des contre-performances sportives associées et du coût du traitement, ces ulcères ont un impact économique majeur pour la filière équine et en particulier les filières courses et sport. La dénomination aujourd’hui utilisée pour décrire ces ulcères est le « syndrome d’ulcération gastrique équin » qui regroupe deux entités distinctes, selon la portion de l’estomac qui est touchée.

Lawsonia intracellularis (LI) is an obligate intracellular gram-negative rod causing equine proliferative enteropathy (EPE). Occasional cases of EPE in foals have been reported in Belgium, but the seroprevalence of equine LI in the country is unknown. The aim of this study was to determine the seroprevalence of LI in adult healthy horses in Belgium. The target population included clinically healthy adult horses, housed in the same premises for the previous 12 months. Serum samples from horses living throughout Belgium were collected and analysed for specific IgG antibodies against LI using a blocking ELISA test. Results were expressed as Percentage of Inhibition (PI). Samples that had a PI <20% were judged as negative, those between 20 and 30% as inconclusive and those >30% were considered positive. A total of 356 blood samples were analysed with 352 horses (98.8%) testing positive, 2 horses (0. 56%) testing negative and 2 horses (0.56%) showing inconclusive results. The high prevalence of positive samples precluded any statistical analysis to test the impact of province of residence, age, breed or gender on the results. In conclusion, the large percentage of seropositive samples obtained in this study confirms a widespread exposure of Belgian horses to LI. Seroconversion is rarely associated to clinical disease, but suggests that EPE should be part of the differential diagnosis in horses with compatible clinical signs (ill-thrift, hypoproteinemia, edema, and diarrhea). These results are in accordance with results of prevalence reported in neighbouring countries (The Netherlands, Germany), whilst other countries (Israel) report a much lower prevalence. [less ▲]

Boxed or at pasture horses are susceptible to be intoxicated directly after ingestion of plants in particular, or indirectly by contamination of food or water. There are many liver toxins. The identification of the agent responsible for intoxication is not easy and samples must be carefully chosen. The objective of this article is to propose a practical approach to cases of suspected toxic hepatopathy. The elements that lead the practitioner to suspect an intoxication, confirmation of the hepatic intoxication and finally treatments to be put in place are discussed. [less ▲]

An atypical case of equine herpes virus 1 in a 6 year old warmblood gelding is admitted at the equine Veterinary Clinic of Liège University. The horse’s symptoms are of a respiratory nature with dry cough, serous secretions and an acute pulmonary hemorrhage with epistaxis. This case also presents urinary symptoms with a polydipsia and polyuria and since at least 3 years prior according to his history, as well as a severe azotemia. Another symptom being the petechiae localized at the respiratory tract level is described and seems to be caused by a vasculitis of the respiratory tract. A polymerase chain reaction (PCR) on complete blood and a nasopharyngeal swab provides positive results for equine herpes virus 1. The acute pulmonary hemorrhage seems to be linked to an inflammation and/or vasculitis of the respiratory tract probably caused by the viral infection. Acute renal insufficiency is diagnosed at the same time as respiratory symptoms appear and could be caused by a vasculitis of the urinary and/or renal tissue, although polydipsia and polyuria have been noticed by the owners for at least three years prior. This case of equine herpes virus 1 shows an atypical respiratory form with a pulmonary hemorrhage allows to consider a possible vascular tropism in the respiratory presentation of the virus, and leads to suspect a multi systemic hit, including the pulmonary and renal tissues.

Dental issues are impacting many horses. Under different types, they can provoke lesions in the oral cavity that will be translated into clinical signs on the horse. Those symptoms will make the owners contact veterinarians. Another frequent cause of calling veterinarians is the colic: potentially severe abdominal pain. The related symptoms are well known and feared by the owners. Different types of colic have been studied in order to search for the causes and risk factors. Several studies have indicated that one type of colic, impactions, would be more frequent when the subject is presenting dental abnormalities, whereas some others deny this hypothesis. Two studies are undertaken in the framework of this end-of-study work. The first one reveals that the horses affected with large colon impaction have a recent dental care history. The second study indicates that horses with displacement of colon are affected by an important count of dental abnormalities. [less ▲]
