Equine protease inhibitor system as a marker for the diagnosis of chronic obstructive pulmonary disease (COPD)
Provedor de dados: 74
Autores: Vinocur,Myriam E.; Brass,Karin E.; Caetano,Alexandre R.; Silva,Letícia F.; Silva,Aline C.; Silva,Carlos A.M.
The protease inhibitor system (PI) was investigated to ascertain if it can be used as a marker of chronic obstructive pulmonary disease (COPD) in thoroughbred horses. Serum samples were taken from healthy thoroughbreds (n = 13) and those diagnosed as having COPD (n = 24) or inflammatory airway disease (IAD, n = 38) as well as from 3,600 undiagnosed thoroughbred horses. PI allelic and genotypic frequencies were estimated using protein electrophoresis on starch and polyacrylamide gels. The four groups of horses showed high genotypic similarity and none of the observed alleles or genotypes of the equine PI system were found to be associated with COPD.

Spi2 gene polymorphism is not associated with recurrent airway obstruction and inflammatory airway disease in thoroughbred horses
Provedor de dados: 74
Autores: Silva,Aline Correa da; Brass,Karin Erica; Loreto,Elgion da Silva; Vinocur,Myriam Elizabeth; Pozzobon,Ricardo; Azevedo,Marcos da Silva.
The aim was to detect the presence of polymorphisms at exons 1, 2, 3 and 4 of the Spi2 gene, and evaluate a possible association between them and recurrent airway obstruction (RAO) or inflammatory airway disease (IAD) in thoroughbred horses, through single-strand conformational-polymorphism (SSCP) screening. Although polymorphism was not detected in exons 1, 2 and 3, three alleles and six genotypes were identified in exon 4. The frequencies of allele A (0.6388) and genotype AA (0.3888) were higher in horses affected by RAO, although no association was found between polymorphism and horses with either RAO or IAD.

Genetic characterization of the Spanish Trotter horse breed using microsatellite markers
Provedor de dados: 74
Autores: Javier Azor,Pedro; Valera,Mercedes; Gómez,María Dolores; Goyache,Félix; Molina,Antonio.
To assist in selection schemes we carried out the first genetic characterization of the Spanish Trotter horse (Trotador Español). We used 16 microsatellite markers to genotype 40 unrelated Spanish trotters, 25 native Balearic horses (11 Menorquina and 14 Mallorquina horses) and 32 Andalusian horses. The observed heterozygosity for the Spanish Trotters was 0.647 ± 0.037 and the expected heterozygosity was 0.696 ± 0.026 while the average number of alleles per locus was 6.0 ± 0.341, these values being similar to the data published for other horse breeds. We also tried to establish the importance of the Mallorquina and Menorquina breeds in the present Spanish Trotter population. Only 9% of the total genetic variability could be attributed to differences...

Genetic variability in the Skyros pony and its relationship with other Greek and foreign horse breeds
Provedor de dados: 74
Autores: Bömcke,Elisabeth; Gengler,Nicolas; Cothran,E. Gus.
In Greece, seven native horse breeds have been identified so far. Among these, the Skyros pony is outstanding through having a distinct phenotype. In the present study, the aim was to assess genetic diversity in this breed, by using different types of genetic loci and available genealogical information. Its relationships with the other Greek, as well as foreign, domestic breeds were also investigated. Through microsatellite and pedigree analysis it appeared that the Skyros presented a similar level of genetic diversity to the other European breeds. Nevertheless, comparisons between DNA-based and pedigree-based results revealed that a loss of genetic diversity had probably already occurred before the beginning of breed registration. Tests indicated the...

Autores: Barker,   Anna B.E.; Warren-Smith,   A.K.
Anecdotal evidence suggests that a horse’s prior fitness level has an effect on the horse’s ability to return to that previous level of fitness. This trial aimed to test this assumption which would benefit horse trainers to create individual fitness programs for horses. Standardised exercise testing was used to compare the progress of two groups of horses during weeks three and seven of a 14-week training program. Group A had undergone a similar training program twelve months previously and Group B had not. Plasma lactate samples and heart rate monitoring were used to assess the levels of fitness of the horses. Analysis of variance showed that there was no significant difference in post-exercise plasma lactate concentration between the groups. The horses...

Carbohydrate metabolism and metabolic disorders in horses
Provedor de dados: 96
Autores: Hoffman,Rhonda M.
Horses evolved consuming primarily fermentable forage carbohydrates, but forage diets have been traditionally supplemented with grain meals rich in starch and sugar in order to provide additional calories, protein and micronutrients. Starch and sugar are important for performance horses, but the consumption starch-rich meals may cause equine digestive and metabolic disorders. The critical capacity for preileal starch digestibility appears to be 0.35 to 0.4% but may be as little, depending on the source of starch. Small intestinal absorption of simple sugars is limited by the activity and expression of two classes of glucose carrier proteins, which are affected by chronic intake of hydrolyzable carbohydrate but may be sluggish to respond to abrupt changes...

Laparoscopy is frequently indicated in cases of peritonitis, intestinal lesions, duodenojejunitis, adhesions, cryptorchidism, internal organ biopsy and diagnosis or abdominal abscesses and tumors. Adequate knowledge about the technique, laparoscopic anatomy and clinical applications wil1 allow laparoscopy to become a routine diagnostic method in equine medicine.

Autores: Coelho,C.M.M.; Lopes,M.C.S.; Flôres,F.N.; Zangirolami Filho,D.; Canola,P.A.; Valadão,C.A.A.
Horner's syndrome (HS) is a sympathetic dysfunction caused by injuries to the sympathetic pathway. A clinical case of HS following common carotid artery transposition and catheterization in a horse is described. The animal presented head and neck sweating with focal skin temperature elevation, facial paralysis and ptosis. Most clinical signs were transient and persisted for two hours following percutaneous catheter removal. Recurrence of clinical signs was observed at subsequent catheterizations. Ptosis endured for 10 months as a consequence of the first catheter placement which demonstrates the importance of careful manipulation of the anatomical structures of the neck when performing any surgical manipulation in this area.

ABSTRACT This study represents a first attempt to rescue germplasm of a traditional domestic equine cited in early Iberian and South American literature as Curraleiro horse. As an effort to identify and possibly characterize this type of horse we accessed traditional knowledge in strategic rural areas. Most areas were configured by hinterland settlements founded by runaway slave communities from the sixteenth century. Twenty interviews were conducted and analyzed using classical Speech Content Analysis. As a result, five response categories were recognized: 1) Identification and location of Curraleiro horses; 2) Characterization of Curraleiro horses; 3) Historical aspects; 4) Curraleiro horse conservation prospects and 5) Sanitary and productive aspects of...

Provedor de dados: 45
Autores: Carvalho,R.; Passos,L.M.F.; Gouvea,A.M.G.; Resende,M.; Martins,A.S.; Franco,G.C.
An ELISA system was applied to study the prevalence of EHV-1 in vaccinated and non-vaccinated Brazilian horses. Serum samples were taken from non-symptomatic pregnant mares, before and after the parturition, and from their neonatal foals. The antigen was prepared from a purified virus fraction (HVE-1 AB1 strain). The ELISA absorbance of 0.3516 was determined as the threshold of negative values. This cut-off level was defined from a selected interval, which determined a sensibility of 100% and a specificity of 94.7%, from a serum collection obtained from pregnant mares and fetuses. In this study, a strong correlation was found between the ELISA and serum neutralization for specific EHV-1 antibody detection.

Provedor de dados: 52
Autores: He,Liangjun; Wang,Shiwei; Deng,Haifeng; Dong,Hong; Chen,Jingbo.
ABSTRACT MicroRNAs (miRNAs) are a class of short non-coding RNAs identified as potent regulators of gene expression. Previous studies have suggested that miRNAs are involved in mammalian spermatogenesis. Stallion fertility is an important trait for the horse breeding industry, but stallion fertility traits are largely ignored in the industry. In this study, we generated expression profiles of miRNAs in foal (immature) and stallion (mature) testes using Solexa sequencing. We identified 438 known and homologous equine miRNAs and 199 novel miRNAs which were distributed among all the chromosomes. The two developmental stages showed significant differences in miRNA expression patterns. Our result expands the horse miRNA database and provided additional...

Autores: DEADO,Antonio Cezar de Oliveira; LOPES,Marco Aurélio Ferreira; GANDOLFI,Waldir.
Gastric ulcer accounts for one of the most important causes of abdominal discomfort in young horses. With the aim of studying the prevalence of lesions (ulcers and/or erosions) and their relationship to factors such as stress, age and sex, sixty quarter horse foals without signs of gastric disease underwent gastroscopy. Foals were divided into four age groups of 15 animals as follows: 1 to 30 days, 31 to 60 days, 61 to 90 days and 91 to 120 days. The prevalence of gastric lesions was 43.3%. Foals aged 61 to ninety days were the most affected (nine of 15). There were no significant differences between ages. Squamous epithelial exfoliation was observed in nine foals (60%) less than thirty days, in six (40%) between 31 to sixty days and only in two foals...

The virulence attributes of 56 Escherichia coli strains isolated from sick horses (secretions of uterine cervices; gastrointestinal and lung fragments of necropsy; diarrheic feces, and tracheal washings) was examined by determining their adherence pattern to HeLa cells and searching for the presence of virulence genes of the various E. coli pathotypes. Two non-adherent strains presented astA, which encodes the enteroaggregative E. coli heat-stable toxin. Twenty-seven strains (48.2%) adhered to HeLa cells, 21 (77.8%) of which presented the aggregative adherence pattern (AA) that characterize the Enteroaggregative E. coli pathotype (EAEC). Nine of the strains presenting AA were isolated from secretions of uterine cervix, including one carrying virulence...

Autores: Laskoski,Luciane Maria; Valadão,Carlos Augusto Araújo; Dittrich,Rosangela Locatelli; Deconto,Ivan; Faleiros,Rafael Resende.
ABSTRACT: Laminitis is a severe podal affection, which pathophysiology remains partially renowned. Ischemic, enzymatic, metabolic and inflammatory mechanisms are connected to the development of laminar lesions. However, few therapeutic measures are effective to prevent or control the severity of acute laminitis and its prodromal stage, which often determines serious complications such as rotation and/or sinking of the distal phalanx and even the loss of hoof. The purpose of this study is to compile the actual knowledge in respect to the pathophysiology and treatment of equine laminitis.

Autores: Ruas,Jerônimo Lopes; Schild,Ana Lucia; Fernandes,Cristina Gevehr; Ferreira,João Luiz Montiel; Müller,Gertrud.
Equine cerebral hydatid disease is described in a 7-year-old, crossbred, female horse. Clinical signs were characterized by circling gait, pressing of head against fences or objects and motor incoordination. On gross examination of the brain the hemispheres were swollen, mainly the left one. On transversal sections, a 5cm X 7cm fluid-filled cyst was observed within the lateral ventricle of the left hemisphere. The cyst extended from the parietal to the occipital lobe, and compressed the third ventricle. There was also marked mid line deviation. Histologically, the brain lesion adjacent to the cyst, was characterized by a piogranulomatous process and vacuolization of neuropil. A diagnosis of equine hydatidosis caused by Echinococcus granulosus was made on...

Effects of two different deep digital flexor tenotomy techniques on distal articular angles of equine cadaver forelimbs
Provedor de dados: 65
Autores: Dearo,Antonio Cezar de Oliveira; Rosa,Vitor Bruno Bianconi; Reichmann,Peter; Oliveira,Milton Luis Ribeiro de.
Deep digital flexor (DDF) tenotomy is a technique employed for years to treat selected disorders of the musculoskeletal system in horses. Although two different surgical approaches (i.e. mid-metacarpal and pastern) have been described for performing the procedure, in vitro quantitative data regarding the modifications induced by either technique on the distal articular angles is lacking. Therefore, the purpose of the study reported here was to investigate the viability of a proposed biomechanical system of induced-traction used to compare the two DDF tenotomy techniques by measuring the distal articular angles of equine cadaver forelimbs. Ten pairs of forelimbs were collected and mounted to a biomechanical system developed to apply traction at the toe...

ABSTRACT: A 10-day old foal presented with a history of acute recumbency and generalized weakness, that progressed to seizure episodes and death. Post mortem examination revealed necrotizing and purulent omphalophlebitis and fibrinopurulent meningoencephalomyelitis. Salmonella Typhimurium was isolated from the central nervous system and determined to be the cause of the meningoencephalomyelitis. Due to the lack of evidence of gastrointestinal disease, the umbilical cord was considered the most likely portal of entry of the bacteria. The isolated S. Typhimurium was resistant to ampicillin and cephalotin, and partially resistant to enrofloxacin. These drugs are commonly used in the treatment of salmonellosis. This is the first report of S. Typhimurium...
