This study aimed to investigate the presence of Strongylus vulgaris on different horse establishments in Romania. A total number of 380 horses were enrolled in the study, representing: three stud farms (n=156); four sport/recreational establishments (n=75); and working horses (n=149). Overall, 106 premises/yards from 17 localities in 9 counties from North-Eastern, Center and Southern Romania were visited. Fresh fecal sample were collected from individual horses and were analyzed by a modified McMaster method for fecal strongyle egg per gram counting. Further, larval cultures were performed for morphological identification of S. vulgaris third stage larvae. Overall, of the investigated horses from studs, sport/recreational units, and working horses, 84.60%, 44.0%, and 79.20%, respectively were positive for strongyle. On coprocultures, cyathostomin-larvae were the most prevalent in all horse-establishment types, while S. vulgaris larvae were found only in working horses (12.1%; n=18). Other strongylin species have been identified, namely S. equinus, S. edentatus, Oesophagodontus robustus, and Triodontophorus spp. all in working horses, and Craterostomum acuticaudatum, in both working horses and horses for sport units. However, further studies are planned by using more sensitive technique for monitoring of S. vulgaris in Romanian horse farms.

Objective: identification of carrier animals of the hereditary anomaly SCID and HYPP of the population of horses bred on breeding horse farms of the Republic of Belarus. Methods: genetic, biological. DNA diagnosis of genotypes in the gene severe combined immunodeficiency (SCID) and hyperkaliemic periodic paralysis (HYPP) was performed using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) in the research laboratory «DNA Technology» of educational establishment «Grodno State Agrarian University». We tested 50 horses of different breeds, kept on different breeding horse farms of Belarus. DNA was isolated from buccal epithelium by perchlorate method with double purification (according to the method of Zinovieva). A study of the genetic structure of the horse population for hereditary anomalies of severe combined immunodeficiency and hyperkalemic periodic paralysis was performed using modern equipment. Amplification was carried out using the C1000 Touch thermal cycler (BioRad, USA). The visualization of the gel was carried out using the gel-documenting system Gel Doc XR + (Bio- Rad, USA). Main results. The use of modern methods for the genetic diagnosis of hereditary diseases of agricultural animals not only at birth to exclude from the process of reproduction of animal carriers of hereditary anomalies, but also reduces funding for their maintenance and cultivation. In the studies we used the PCR method based on the use of specific oligonucleotides with which the amplification of the necessary fragment of the 163 gene occurs in healthy individuals and 158 in the mutation carriers, which makes it possible to identify the hereditary SCID disease. We tested 50 animals of the upper and Arabian breeds, as well as horses with an admixture of Arabian blood, among which no carriers of the hereditary anomaly were found. In studies, the PCR-RFLP analysis method was used, based on the use of distinctive primers due to which the necessary fragment of the gene is amplified, which makes it possible to identify the hereditary HYPP disease. Amplified fragments were subjected to the action of restriction enzymes, with the help of which it is possible to determine the genotype of the animal under study. We tested 50 animals of the upper and Arabian breeds, as well as horses with an admixture of Arabian blood, among which no carriers of the hereditary anomaly were found. Conclusions. Severe combined immunodeficiency (SCID) is an autosomal recessive disease that occurs in humans, mice, horses and dogs. Carriers of this hereditary disease are born without visible anomalies, but after 2 weeks they become ill from any infection and die, since they can not develop an antigen-specific immune response. Hyperkaliemic periodic paralysis (HYPP) is an autosomal dominant disease that occurs in horses at the age of 2, when the animal begins, is strengthened to exercise. Symptoms of this disease are weakness of the muscles, periodic spasms, paralysis, which can lead to death. Presumably, there were no carriers of severe combined immunodeficiency in the Republic of Belarus, since breeding farms for breeding horses did not use biological material of Arabian and local breeds of horses for insemination. With subsequent importation of Arabian horses, as well as breeds that have an admixture of Arab blood, it is necessary to conduct DNA testing for the presence of severe combined immunodeficiency (SCID). According to the results of the conducted studies to identify the hereditary disease of hyperkalemic periodic paralysis (HYPP) in the horse population, no carriers were found, as well as sick animals. Presumably, there were no carriers of this disease on the territory of the republic, as evidenced by parallel studies conducted in other European countries, where no carrier or sick animal was found. This suggests that the disease was localized during the time, and also did not leave the territory of the American continent.

Abstract BACKGROUND Medical specialty camps have provided children with unique psychosocial experiences; however, dedicated pediatric brain tumor camps are rare in the United States, except in limited locations. This study aimed to glean caregiver perceptions from a dedicated family brain tumor camp, and to learn about the family experience with navigating a neuro-oncology diagnosis. DESIGN: Flying Horse Farms is a non-profit organization located in Mt. Gilead, Ohio and a member of the SeriousFun Children’s Network, a global community of camps and programs serving children with serious illnesses and their families, at no cost. The institutional review board at Ohio University approved this project at Flying Horse Farms in September 2017. Consent from caregivers was obtained prior to participation in the study, which provided the opportunity to complete three separate phases: a pre-camp survey, attend a semi-structured interview during the weekend, and complete a post-camp survey. RESULTS 11 families were present for the weekend, and 10 families consented to participate in all three phases. For 6 families, this was their first experience at Flying Horse Farms. For 9 of the 10 families, the camp met their expectations. Additionally, 9 out of 10 families reported they would be interested in attending a diagnosis specific camp again in the future. CONCLUSIONS This work demonstrates the feasibility of conducting research at a medical specialty camp without restricting the camp experience. Better understanding of the attendee’s attitudes toward camp may enhance the experience and the neuro-oncology journey in the future.

AbstractKnowledge regarding helminth control strategies and nematode infection of horses in Ireland is limited and only one study has been published recently. This present study was designed to investigate the current helminth control strategies followed by horse owners in Ireland. A questionnaire was formulated to collect data on general grazing, pasture management and deworming strategies including the use of fecal egg counts. Questionnaires were emailed to 700 members of the Irish Thoroughbred Breeders Association and Horse Sport Ireland. Only 78 questionnaires were returned. Respondents indicated that horses are grazed for 16–24 h day−1during the summer and autumn (89% and 65%, respectively). Removing feces from the pasture was implemented by 37.6% of respondents. Few (22.2%) owners kept horses off pasture after worming. Overall, ivermectin and moxidectin were the most commonly administered anthelmintics in 2014 by 75% and 62% of respondents, respectively. Benzimidazole and pyrantel drugs were used by 53% and 35% of respondents, respectively. The majority of farms (81.4%) treated horses 4–5 times per year and 74.2% only estimated the weight of the horses visually. The findings of this study illustrates that many stud managers/owners do not follow best practice with regard to helminth control and more education is needed.

ABSTRACT Pulsed-field gel electrophoresis of restriction endonuclease-digested genomic DNA from a large collection of clinical isolates of Rhodococcus equi, an important pathogen of foals, was used to compare strain distribution between farms and over time. Forty-four strains were found among 209 isolates, with 5 of these accounting for over half the isolates and the 22 strains isolated more than once accounting for 90% of the isolates. The average genotypic diversity on each farm and in each year was found to be less than the genotypic diversity of the isolates taken as a whole, with 5.2% of the total diversity being due to differences between farms and 5.5% to differences between years. A small number of strains on each farm were found to have caused at least half the clinical cases of disease, and these varied between farms and, to a lesser extent, years. Most strains were found on more than one farm, and some very similar restriction patterns were found among isolates from different continents, indicating that strains can be very widespread. Multiple strains were isolated in five of the six cases in which more than one isolate from a single foal was examined, indicating that disease may commonly be caused by simultaneous infection with multiple strains. It was concluded that there are a number of different strains of R. equi which carry the vapA gene, and these strains tend to be widespread, but individual farms tend to have particular strains associated with them.
