Mitochondrial variability in the D-loop of four equine breeds shown by PCR-SSCP analysis
Provedor de dados: 74
Autores: Mirol,Patricia M.; Peral García,P.; Dulout,F.N.
A fragment of 466 base pairs from a highly variable peripheral region of the mitochondrial D-loop of horses was amplified and analyzed by single stranded conformational polymorphism (SSCP). Fourteen distinct SSCP variants were detected in 100 horses belonging to four breeds (Arabian, ARB; Thoroughbred, TB; Argentinian Creole, ARC; and Peruvian Paso from Argentina, PPA). Each breed showed four to eight SSCP variants, many of which were shared between two or three of the studied breeds. Arabian horses were the most variable (eigth variants), with three variants unique to the breed. PPA and ARC showed two and one characteristic SSCP variants, respectively, while TB shared all its variants with at least one of the other breeds. An analysis based on the...

O cavalo Pantaneiro caracteriza-se pela sua rusticidade e adaptacao as condicoes ecologicas do Pantanal, fruto de selecao natural por mais de dois seculos. Como animal de trabalho, constitui fator de importancia economica e social auxiliando nas producao pecuaria, alem de contribuir para a fixacao do homem na regiao. A partir de 1900, cruzamentos indiscriminados com outras racas, alem da disseminacao de enfermidades, como o "mal-de-cadeiras" (tripanosomose) e mais recentemente a anemia infecciosa equina (AIE), contribuiram para a diminuicao do seu efetivo. A AIE, enfermidade endemica para a regiao, apresenta incidencia media de 42,7% (SILVA, et al. 1995), sendo considerada, atualmente o principal fator limitante para a expansao da criacao de equino no...

Os cavalos introduzidos no Pantanal pelos conquistadores durante a epoca da colonizacao, encontraram na regiao condicoes ambientais propicias para sua multiplicacao. Como consequencia dos processos adaptativos e da selecao natural por mais de dois seculos e com pouca ou nenhuma interferencia antropica, surgiu um tipo adaptado ao meio. Com o desenvolvimento da pecuaria na regiao, o cavalo Pantaneiro constituiu-se num fator de importancia economica e social, tornando-se imprescindivel em trabalhos de gado e no transporte regional.

The morphological characteristics of the hooves of two groups of horses were studied. The first group was comprised of six adult animals without any treatment and served as the control. The other group, comprised of seven horses, received carbohydrates overload orally. Of these, 71% developed laminitis between 36 and 48 hours after carbohydrate administration. After 48 hours of induction, the animals were sacrificed and their fore limbs and hindlimbs were removed for histologic study. Tissue sections 5 to 7 µm thick were obtained, stained with hematoxylin-eosin (H&amp;E) or periodic acid Schiff's (PAS), and then examined by light microscopy. It was possible to identify in horses from the laminitis group, morphological and structural changes in the...

Autores: MURASE, Harutaka; NIWA, Hidekazu; KATAYAMA, Yoshinari; SATO, Fumio; HADA, Tetsuro; NAMBO, Yasuo.
Fungal placentitis is an infectious disease inducing abortion in pregnant mares. In the present report, we describe a field case of abortion caused by fungal placentitis with consecutive examinations. The progesterone level and combined thickness of the uterus and placenta (CTUP) were abnormal before the onset of clinical signs. Additionally, the estradiol level started to change before the appearance of clinical signs. Abnormal serum amyloid A values and an abnormal fetal heart rate were observed after the onset of clinical signs. The present report demonstrates that the progesterone level and CTUP may be adequate as early diagnostic markers of fungal placentitis and bacterial infection. Endocrinological evaluation based on cutoff values or serial...

From previous cDNA subtraction studies analyzing gene expression in equine endometrium, high lipocalin 2 (LCN2) mRNA expression was found in the gravid endometrium. In the uterus, LCN2 may transport hydrophobic molecules and siderophores with iron, or may form a complex with another protein, however, the expression of uterine LCN2 beyond day 20 of equine pregnancy and its receptor has not been characterized. To study the expression and potential roles of uterine LCN2 from pre-implantation to mid-gestation period, stage-specific endometrial samples were obtained from day 13 (day 0 = ovulation) cyclic and days 13, 19, 25, and 60 to 131 pregnant mares. Expression of LCN2 mRNA increased in day 19 gravid endometrium and was abundant from day 60 onward. The...

A 17-year-old, gray Thoroughbred gelding was presented with recurrent epistaxis following exercise for over one year. Multidetector-row computed tomographic (MDCT) examination of the head performed under general anesthesia indicated the presence of malignant melanoma. MDCT examination revealed the exact location and size of masses in the right guttural pouch first identified by endoscopy and in the left guttural pouch unidentified by endoscopy. MDCT examination revealed the presence of a blood clot that filled the right maxillary sinus. The horse was euthanized due to poor prognosis as a riding horse and the owner's decision, and MDCT findings were confirmed by postmortem examination. MDCT is suggested as a useful technique for diagnosis of head problems...

Autores: SASAKI, Naoki; YAMADA, Haruo; HARA, Shigeo; 佐々木, 直樹.
This study was designed to investigate gastrointestinal dysfunctions, especially the effects of gastrointestinal prokinetic agents on digestive disorders involving lowered motility. The effects of α2-adrenergic agonists for treating acute abdominal disorders involving intestinal torsion in horses were also investigated. The results are as follows: (1) It appeared that the functions of migrating contractions (MC) in horses were to transfer the contents of the digestive tract as soon as possible to the cecum and colon, in addition to maintaining homeostatis in the digestive tract. (2) Motilin was seen to be involved in the regulation mechanism of intestinal motility in the horse as well as in humans and dogs, and brought about MC. (3) The intravenous...

Effects of Orally Administrated Mosapride, a 5-HT4 Receptor Agonist on the Digestive Tract of Horses
Provedor de dados: 19
Autores: SASAKI, Naoki; LEE, Inhyung; AYUKAWA, Yu; YAMADA, Haruo; 佐々木, 直樹.
The effects of mosapride, a 5-hydroxytryptamine 4 (5-HT4) receptor agonist, on the motility of horse small intestine were examined by means of electrointestinography (EIG). Six adult healthy thoroughbreds were used, in which EIG signals from the small intestine were measured by a Degetorappar EGG system. Mosapride, dissolved in 200 ml water, was orally administered at a dose of 2 mg/kg. The total power of EIG signals at a frequency band of 3 cpm was 419.1 ± 122.0 (μV) 2 × cpm (n=6) before, and 2,093.6 ± 850.0 (μV)2 × cpm (n=6) after the drug administration, the latter mean value being significantly greater than the former. This result suggests that mosapride has a prokinetic action on the motility of horse small intestine.

The prokinetic effect of the 5-HT4 receptor agonist mosapride was evaluated in seven healthy thoroughbreds. Mosapride was orally administerd at doses of 0.5, 1.0 or 1.5 mg/kg. The breath 13CO2/12CO2 rate (Δ13CO2), an indirect indicator for the rate of gastric empting, was measured at appropriate points for 4 hr after drug administration. There was a significant increase compared with the control value at 15, 20 and 165 min for 0.5 mg/kg, 30 min at 1.0 mg/kg and 165 min for 1.5 mg/kg. The results suggest that mosapride may facilitate the gastric emptying in horses.

Provedor de dados: 19
Autores: MURASE, Harutaka; SAITO, Shigeaki; AMAYA, Tomohiko; SATO, Fumio; BALL, Barry Allen; NAMBO, Yasuo.
Anti-Müllerian hormone (AMH), a glycoprotein secreted from the fetal testis, is responsible for regression of the Müllerian duct in the male fetus. The aim of this study was to evaluate the usefulness of serum AMH as a biomarker for diagnosis of cryptorchidism in horses. Serum AMH concentrations were measured in intact stallions, hemi-castrated unilateral cryptorchid stallions, and geldings. In addition, expression of AMH was characterized in cryptorchid testes by immunohistochemistry. Serum AMH was detected in intact stallions (n=11, 13.3 ± 1.8 ng/ml) and in hemi-castrated cryptorchid stallions (n=8, 17.6 ± 3.0 ng/ml), but not in geldings (n=6, all data were below the limit of detection). Immunolabeling for AMH was detected in Sertoli cells of undescended...

Techniques for measuring hydrogen (H2) and methane (CH4) levels in breaths were assessed in horses with gastrointestinal (GI) diseases. A total of 31 horses were studied: 11 healthy horses (Group A), 10 horses with GI diseases (Group B), and 10 horses with diseases without GI involvement (Group C). Expired gases were measured using gas chromatography. CH4 levels in Group A were significantly lower than those in Group B. In Group B, CH4 levels were significantly higher after treatment. Fluctuations in H2 and CH4 levels in breath were associated with changes in GI function.

Autores: SASAKI, Naoki; LEE, Inhyung; AYUKAWA, Yu; YAMADA, Haruo; 佐々木, 直樹.
It is thought that in order to effectively treat gastrointestinal dysfunction, it should be detected at an early stage. The present study aimed to observe the movement via Electrointestinography (EIG) in the small intestine, cecum, right ventral colon and right dorsal colon, and to examine the procedure for assessing gastrointestinal function. Seven healthy thoroughbred horses were used. They were allowed food twice a day. EIG was measured at ten-minute intervals over a 24 hr period, and running spectral analysis was used. As a result, it was clear that EIG could non-invasively assess gastrointestinal function by setting the cut-off value of the frequency band to 1.8-12.0 cpm for a part of the digestive tract which is in a comparatively fixed position. The...

Autores: SASAKI, Naoki; MORITA, Yoshinori; MORIYAMA, Tomoe; YAMADA, Haruo; 佐々木, 直樹.
The purpose of this study was to evaluate the effect of the canine cranial cruciate ligament repair system on laryngeal hemiplegia in heavy draft horses. Twenty-four heavy draft horses diagnosed with grade 4 laryngeal hemiplegia were allocated to either the prosthetic laryngoplasty (PL) group (n=14) or a canine cranial cruciate ligament repair system (CCCLRS) group (n=10). Right to left angle quotients (RLQs) of abductions of the arytenoid cartilages were endoscopically evaluated before and after surgery. Post-operative RLQs in the CCCLRS group were significantly lower than those of the PL group (P&lt;0.01). The canine cranial cruciate ligament repair system was revealed to be a good surgical procedure for laryngeal hemiplegia in heavy draft horses.

Equine bone scintigraphy is usually performed with horses in standing position under sedation. However, swaying motion often leads to poor-quality images. To examine the usefulness of motion correction (MC) processing, equine bone scintigrams were evaluated using Scheffé’s method of paired comparisons. A significant difference in evaluation scores was detected by analysis of variance (F test, P&lt;0.01). According to all observers, Yardstick analysis scores were higher for images use of MC processing than for those no use of MC processing, for all parts. Overall scores of 5 observers were as follows: without MC 100% acquisition time (AT, lowest), use of MC with 25% AT, MC 50% AT, MC 75% AT and MC 100% AT (highest). Thus, MC processing shortens AT in equine...

In this equine study, we used an MDCT unit and a trestle for large animals to assess the utility of MDCT in the diagnosis locomotor system disorders and problems in the head and spine. We used a mature thoroughbred horse under general anesthesia and 5 specimens. For specimens, MDCT images were compared with other images taken by a computed radiography X-ray unit. In the live horse, use of the trestle for large animals enabled scanning under general anesthesia. In specimens, MDCT created 3D images of the fractured lesions and evaluation of multiple cross-sectional and sagittal images was possible. Further, multiple sagittal images and virtual endoscopic images revealed details of a spinal canal stenosis in the swayback case. These results indicate that MDCT...

Show Quality Quarter Horse Auctions: Price Determinants and Buy-Back Practices
Provedor de dados: 31
Autores: Taylor,   Mykel R.; Dhuyvetter,   Kevin C.; Kastens,   Terry L.; Douthit,   Megan; Marsh,   Thomas L.
This study estimates the price determinants of show quality quarter horses sold at auction. Several characteristics including genetic and physical traits, quality of pedigree, and performance record of the horse, as well as the horse's offspring, were found to significantly impact selling price. Sale order positively affected price and appears to be driven by buyers rather than intentional ordering of the horses. A common practice at horse auctions is for the seller to reject the final bid offered and buy back the horse. Model-predicted prices for these buy-back horses indicate they are not undervalued by the final bids, based on their characteristics.

HEDONIC PRICING, INFORMATION, AND THE MARKET FOR THOROUGHBRED YEARLINGS
Provedor de dados: 31
Autores: Vickner,   Steven S.; Koch,   Stephen I.
Building on the 1997 work of Chezum and Wimmer, and the 1998 work of Lansford, Freeman, Topliff, and Walker, we estimated a hedonic hammer price model on a random and representative sample of 212 yearlings from the 1999 Keeneland September Yearling Sale. Explanatory variables representing day of sale, age of yearling, stud fee, racing performance of sire and dam, geographic origin of yearling, and yearling health information were statistically significant. In each model, we failed to reject the null hypothesis of no adverse selection; sellers who breed and race horses did not receive a statistically significant price penalty on their yearlings sold in this auction, compared to sellers who just breed horses.

The effect of the utilization of three semen protocols (Inra 82®, Merck Gema and Botu-crio®) and two filling techniques (0.25 and 0.50 mL straws) in Mangalarga Marchador stallions were studied in this experiment. Sperm parameters were assessed during processing and post-freezing. No interactions between the protocols and type of filling were observed, so they were assessed separately. Sperm parameters were not altered when the extender was added to the centrifugation; however, there was reduction of motility and strength when freezing extenders were added. The Botu-crio® protocol preserved the parameters of total and progressive sperm motility, smoothed path velocity (µm/s), straight line velocity (µm/s), track velocity (µm/s) and the average and fast...

ABSTRACT This study aimed to verify whether the criterion of exhibition contests adopted for Campolina and Mangalarga Marchador breeds has been successful in recent years, i.e., if the subsequent generations have the morphology recommended by the standard of the breed allied with high-quality marcha, a four-beat ambling gait. The classifications achieved by each horse during national horse shows in morphology and gait contests underwent Spearman's correlation to verify the number of contests with a correlation between the classifications in the two judgments and those with no correlation. Next, the number of contests with or without such correlation underwent a frequency distribution test considering the variables breed, year, age, marcha category, and...

Antioxidant supplementation to the exercising horse
Provedor de dados: 96
Autores: Williams,Carey A.
Evidence of oxidative stress in horses has been described in reports dealing with intense and endurance exercise. Oxidative stress occurs when antioxidant systems are insufficient causing oxidation to potentially damage DNA, proteins, and lipids, and contribute to degenerative changes. Vitamin E is the most commonly supplemented antioxidant in horses and has been shown that horses in exercise conditioning may require higher intakes of vitamin E than recommended. Also in various species vitamin C potentiates the effects of vitamin E; however, under maintenance conditions horses have the ability to synthesize sufficient ascorbate, the demand increases as stress on the body is increased. Competitive endurance horses were estimated to consume 1.2 to 5-times...

Linking dietary energy and skeletal development in the horse
Provedor de dados: 96
Autores: Staniar,William Burton.
Athletic production is what is sought from the horse. As mammary development is important to the dairy cow, skeletal development is important to horses meeting their production goals. As any integrative physiologist will appreciate, the variables that come together to result in optimal skeletal development are complex. Nutrition is one of these, and it contains two broad variables; the supply of dietary nutrients and energy. This presentation will focus on dietary energy and its links with skeletal development. I propose that it is not simply the amount of dietary energy, but the way and from that that energy is supplied that impacts skeletal development. Through an understanding of how dietary energy impact skeletal development, more precise feeding...

Autores: Thomassian, Armen.
Reestablishment of the normal intestinal transit in horses with sharp abdominal discomfort has been a major challenge even for the most experienced professionals in equine practice and surgery. Major procedures to control and repair gastrointestinal motility demand periodic observation of physiological parameters, intravenous administration of fluids to control hypoperfusion and electrolyte balance and digestive decompression by nasogastric intubation and cecum puncture. These emergency procedures are adopted whatever the etiopathogeny of the colic. Besides the traditional procedures, the veterinarian can also use acupuncture or even surgical intervention in situations where no responses were obtained by using the conservative therapy or when the case...

Although laparoscopic techniques have been known and used in horses since 1970, their clinical use has improved only during the last years. 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: Ribeiro, Max Gimenez; Nicoletti, José Luiz de Mello; Thomassian, Armen; Hussni, Carlos Alberto; Alves, Ana Liz Garcia.
The aim of this study was to investigate the clinical, radiological and anatomopathological evolution of experimentally induced bone perforating lesions in the distal phalanx of normal horses. Eight adult horses of both sexes totally free of feet disorders were used in the trial. Lesions were produced through the sole of the distal phalanx, using a miller and an electric drill. Results demonstrated that the technique used allowed a complete and precise approach to the pedal bone; lesions were repaired without any impairment to locomotion. This technique may be an alternative for the usual bone curettage of septic pedal osteitis, keratoma, distal phalangeal fracture and sequestration and draining of foot abscess.

Equine metabolic syndrome in Colombian creole horse: case report
Provedor de dados: 45
Autores: Castillo,C.A.; Jaramillo,C.; Loaiza,M.J.; Blanco,R.
ABSTRACT The equine metabolic syndrome is a condition that can be recognized because of obesity, insulin resistance and laminitis. Genetic factors could play a role in the occurrence of this syndrome. Certain breeds such as ponies (including the South American creole horses) have a lower sensibility to insulin and a higher prevalence of hyperinsulinemia. The environment and management conditions, such as overfeeding and lack of exercise are factors that bring a propensity for obesity. The adipose tissue works as an endocrine organ producing hormones (adipokines or adipocytokines) that affect the horse´s metabolism. The objective of this report is to describe the first case report of a Colombian creole mare with a metabolic syndrome, diagnosed by means of...

Stem cell therapy has shown promising results in tendinitis and osteoarthritis in equine medicine. The purpose of this work was to characterize the adipose-derived mesenchymal stem cells (AdMSCs) in horses through (1) the assessment of the capacity of progenitor cells to perform adipogenic, osteogenic and chondrogenic differentiation; and (2) flow cytometry analysis using the stemness related markers: CD44, CD90, CD105 and MHC Class II. Five mixed-breed horses, aged 2-4 years-old were used to collect adipose tissue from the base of the tail. After isolation and culture of AdMSCs, immunophenotypic characterization was performed through flow cytometry. There was a high expression of CD44, CD90 and CD105, and no expression of MHC Class II markers. The...

Autores: Canola,P.A.; Lacerda Neto,J.C.; Canola,J.C.
The left displacement of the large colon, a condition that commonly occurs in horses, has two clinical manifestations. Different treatments including medical treatment, rolling the horse under general anesthesia or surgical correction have been recommended. The diagnosis can often be made by rectal examination and confirmed by percutaneous ultrasonography. During the period between 2004 and 2009, 11 horses were treated for left displacement of the large colon by rolling the horses under general anesthesia, using a slightly different technique than the ones previously described. The clinical case selection was based on rectal palpation confirmed with ultrasonogram. Nine animals were successfully treated and two had to be submitted to surgery after three...

Brucella spp. in equines slaughtered in the south region of Brazil
Provedor de dados: 45
Autores: Santos,R.F.; Silva,G.C.P.; Assis,N.A.; Mathias,L.A.
ABSTRACT Bacteria of the genus Brucella are widespread in many countries. These microorganisms can infect humans and many wild and domestic animal species. These bacteria have zoonotic potential, and can cause economic and public health problems since they can be transmitted by direct contact with sick animals, through consumption of contaminated milk, raw meat and its derivatives (Soares et al., 2015). Brucellosis is considered a chronic evolving disease, unusual in horses, predominantly caused by Brucella abortus. However, it is not characterized by reproductive disorders in horses, but primarily by abscess in the cervical region, bursa, tendons, and joints. Transmission is likely to occur via ingestion of contaminated water and pastures, especially in...

Autores: Melo,M.I.V.; Henry,M.; Beker,A.R.C.L.
The hypoosmotic test (HO) was used to evaluate plasmatic membrane integrity of equine chilled semen and to estimate the correlation between the results of the HO test and those from applied routine exams of semen. The semen of seven stallions was preserved at 5ºC in three different extenders. Each ejaculate was diluted in three extenders, Kenney (K), Baken with 3% of egg yolk (B3) and Baken with 10% of egg yolk (B10), and chilled at 5ºC. The total motility (MT), progressive motility (MP), spermatic vigor (V), normal spermatic morphology (NOR) and HO test were used to evaluate semen immediately after collection and at 24 hour-intervals. Spermatic longevity was defined as the time taken to the progressive motility to decline under 10%. Semen diluted in B3...

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...

ABSTRACT Differences in hoof balance between horses, mules and donkeys were identified in order to form more specific considerations for proper management of the animals. Measurements of the natural dimensions of hooves in sixty animals were used: 20 horses from the Crioulo breed, 20 mules and 20 donkeys from the Pêga breed. Liveweight was estimated using the correlation equations in each species by heart girth. Using a caliper rule, tape measure and hoof gauge, measurements of the length and width of the frog, hoof height, angle of heel, medial and lateral dorsal length, angle of the toe and crown circumference of the hooves of forelimbs and hindlimb were taken. Within each group the hooves of the hindlimbs exhibited narrower measurements than the hooves...

Provedor de dados: 45
Autores: Carvalho,R.; Passos,L.M.F.; Oliveira,A.M.; Henry,M.; Martins,A.S.
The genome of one equine embryo and three equine semen specimens collected from a Brazilian farm were tested by polymerase chain reaction (PCR) for the presence of EHV-1 and EHV-4-specific timidine kinase (TK) sequences. The PCR detected specific EHV-1 TK gene sequences in all samples tested. The peripheral blood leukocytes (PBL) of the embryo donor mare also was amplified by EHV-1 TK primers. Infectious virus was not recovered from any specimens. The animals did not show any clinical signal of EHV-1 or EHV-4 infections. EHV-4 was not detected in the studied specimens. The results indicate that PCR was more sensitive than virus isolation in cell culture for detecting EHV-1 in semen of carrier horses.

Autores: Lima,P.A.; Eckstein,C.; Ecco,R.; Santos,R.L.
ABSTRACT The aim of this report is to describe a case of marked osseous metaplasia in the placenta associated with abortion in a mare. A 19-year-old Campolina mare with a history of multiple parturitions and absence of reproductive failure, aborted a fetus with approximately six months of gestation. There were no gross changes in the fetus and the placenta. Microscopically, there was multifocal replacement of fetal connective mesenchyme of the chorionic villi with well differentiated and partially mineralized osseous tissue (confirmed by von Kossa staining). To further characterize the collagenous component of the lesion, sections of the placenta were stained with Masson’s trichrome and Picrosirius red. Osseous tissue deposition had abundance of type I...

The heat conduction microcalorimeter can be used to evaluate the metabolic rates of the sperm cell. Two ejaculates of four stallions were cooled to +5ºC and checked for sperm motility (bright field microscopy), viability (eosin 3%), functional membrane integrity (hyposmotic swelling test), and heat production (microcalorimetry). Glucose and sperm cell concentrations were determined in order to measure the heat outputs resulting from sperm metabolism. Sperm viability, membrane integrity and sperm motility did not differ among the different glucose concentrations tested. Nevertheless, the highest heat output detected by the microcalorimeter was obtained with 6 mM glucose and 10(8) spermatozoa/mL. Since conduction microcalorimetry offered additional...

Osteoarthritis in horses - Part 1: relationship between clinical and radiographic examination for the diagnosis
Provedor de dados: 52
Autores: Souza,Maria Verônica de.
ABSTRACT Locomotor disorders are very common in the equine clinic, which may be partly due to the different types of activities horses develop. Osteoarthritis (OA), commonly known as degenerative joint disease, presents an considerable role in the series of disorders of the musculoskeletal system and may be associated with other problems such as navicular syndrome, periostitis or osteochondrosis. This affection causes progressive deterioration of articular cartilage, accompanied by bone and soft-tissue periarticular changes. In fact, it results from a complex interaction between biochemical and biomechanical factors. The objective of this article is to review information about clinical and radiographic findings of OA, the biochemical and biomechanical...

ABSTRACT: The problem considered in this review is related to the frequent use of corticosteroids (COs) (i.e. steroids) in the practice of equine medicine and surgery as a therapeutic strategy in the treatment of degenerative joint disease, commonly known as osteoarthritis (OA). This disease is one of the most common among the equine musculoskeletal diseases, and is clinically characterized by pain, lameness, joint effusion at the initial stage, which usually reduces with the progression of the disease, and reduced physical performance. Although steroids are considered excellent drugs in the control of clinical signs resulting from osteoarthritis, they also influence cellular activity through activation of various signaling mechanisms. However, they can...

Autores: Gonçalves,Daniela Dib; Carreira,Teresa; Nunes,Mónica; Benitez,Aline; Lopes-Mori,Fabiana Maria Ruiz; Vidotto,Odilon; Freitas,Julio Cesar de; Vieira,Maria Luísa.
The aim of this study was to investigate the presence of DNA of Borrelia burgdorferi sensu lato (s.l.) in ticks that feed on horses used for animal traction in rural Jataizinho, Parana, Brazil. Between February and June 2008, a total of 224 ticks was collected of which 75% were identified as Dermacentor nitens and 25% as Amblyomma cajenense. To amplify B. burgdorferi s.l. DNA, the intergenic space region (ISR) between the 5S (rrf) 23S (rrl) rRNA genes was used as targets for nested-PCR. Two ticks of the D. nitens species were positive for B. burgdorferi s.l. Both species showed a fragment of 184 bp, but the sequencing revealed 99.9% homology with the B. burgdorferi sensu stricto (s.s.) strain B31. These results showed, for the first time, the presence of...

Abstract Borreliosis caused by Borrelia burgdorferi sensu lato is a cosmopolitan zoonosis studied worldwide; it is called Lyme disease in many countries of the Northern Hemisphere and Lyme-like or Baggio-Yoshinari Syndrome in Brazil. However, despite the increasing number of suspect cases, this disease is still neglected in Brazil by the medical and veterinary communities. Brazilian Lyme-like borreliosis likely involves capybaras as reservoirs and Amblyomma and Rhipicephalus ticks as vectors. Thus, domestic animals can serve as key carriers in pathogen dissemination. This zoonosis has been little studied in horses in Brazil. The first survey was performed in the state of Rio de Janeiro, and this Brazilian Borreliosis exhibits many differences from the...

ABSTRACT: Renal cell carcinoma, especially with extensive involvement of peritoneal cavity, is rarely described in horses. This study described a case of renal cell carcinoma in an 8-year-old mare, which presented with an enlargement in the left flank, decreased appetite and straining to defecate. Clinically, a tumor in the left retroperitoneal space was detected by rectal examination and ultrasonography. The animal died after one month of clinical evolution. At necropsy, the left kidney was completely effaced by a 50cm in diameter, irregular, round, lobulated cystic mass with necro-hemorrhagic areas. Within the peritoneal cavity, there was severe hemoperitoneum and numerous sessile and pedunculated masses ranging from 2.0 to 15.0cm diameter that were...

Despite of the substantial role of Clostridium difficile in causing diarrhea and colitis in foals, there have been no confirmed diagnoses of disease caused by this bacteria in Brazil. In this paper, we describe confirmed cases of colitis caused by C. difficile in two foals in Brazil. Two five-month-old foals with a five-day history of diarrhea after antibiotic treatment for a respiratory disease were treated at the Veterinary Hospital of the Universidade Federal de Minas Gerais. C. difficile A/B toxins were detected, and toxigenic strains of C. difficile were isolated from the foals' feces. The treatment was based on fluid therapy and antibiotics (metronidazole and ceftiofur), and the animals experienced a gradual recovery. The association between the...

Multi-drug resistance gene (MDR1) and opioid analgesia in horses
Provedor de dados: 65
Autores: Natalini,Cláudio Corrêa; Cunha,Anderson Fávaro da; Linardi,Renata Lehn.
Opioid absorption in the intestinal tract as well as its effects in the central nervous system is modulated by the P-glycoprotein (P-gp) encoded in the Multi-drug Resistance gene (MDR1) also named ATP-binding cassete, subfamily B, member 1 (ABCB1). This MDR1 gene acts as a selective pump. The expression of this protein in humans and rodents inhibits cellular uptake of substrate opioids. The presence of the intestinal iso-enzyme CYP3A4 associated with MDR1 gene decreases the opioid analgesic activity due to an increase in intestinal metabolism, with a predicted intestinal first pass extraction around 20% which significantly influences the oral availability of opioids. In the central nervous system, P-gp expression decreases opioid neuronal uptake...

Autores: Moreira,Rodrigo Crispim; Graaf,Guilherme Maia Mulder Van De; Pereira,César Augusto; Zoppa,André Luis do Valle De.
ABSTRACT: Often fractures of long bones in horses are comminuted and form bone gaps, which represent a major challenge for the fixation of these fractures by loss of contact between the fragments. Bone grafts help in treating this kind of fracture and synthetic materials have been gaining ground because of the limitations of autologous and heterologous grafts. In this study were performed compressive non destructive test in 10 bones with complete cross-bone gap in mid-diaphyseal of the third metacarpal bone of horses. Using a mechanism of "crossing" the 10 bones were used in the three groups (control, castor oil poliuretane and chitosan) according to the filling material. After the test with maximum load of 1000N bone had a gap filled by another material...

Autores: Paixão,Tatiane Alves da; Rêgo,Isabela Oliveira de Paula; Santos,Renato de Lima.
A retrospective study (1942 to 2005) of histopathological lesions included samples of central nervous system (SNC) from 203 animals in the Equidae family. A total of 42.4% of these samples had significant pathological changes, which were classified as inflammatory (62.8%), degenerative (25.6%), circulatory (10.5%), and neoplasic (1.1%) lesions. Immunohistochemistry anti-Sarcocystis neurona antigens was performed in all the cases with inflammatory changes (54), of which one of the case of encephalitis resulted positive to immunostaining. Although evidence of EPM (Equine Protozoal Myeloencephalitis) has been previously reported in Brazil, to the best of our knowledge, this is the first report in which characteristic EPM lesion was associated with anti-S....

Identification of multi-drug resistance gene (MDR1) in equine ileum
Provedor de dados: 65
Autores: Natalini,Cláudio Corrêa; Linardi,Renata Lehn.
P-glycoprotein (P-gp) is a membrane transporter encoded in the Multi-drug Resistance (MDR1) gene expressed in several normal tissues and over expressed in tumor cells. P-gp was already identified in different species but not yet in equine. MDR1 gene and P-gp are able to interfere with bioavailability and disposition of several drugs, altering pharmacokinetic and pharmacodinamic of drugs. The presence of the MDR1 and P-gp in the central nervous system blocks the entry of certain drugs in this tissue and reduces drug absorption and enhances drug elimination when P-gp and MDR1 are presented in the gastrointestinal tract. This study showed that the MDR1 gene is present in equine ileum. Future studies on the impact of the P-glycoprotein encoded gene MDR1 on...

Provedor de dados: 65
Autores: Silva,Rodrigo Otávio Silveira; Oliveira Junior,Carlos Augusto; Guedes,Roberto Maurício Carvalho; Lobato,Francisco Carlos Faria.
Clostridium perfringens is a gram-positive, anaerobic, fermentative, spore-forming bacillus that may be found in the environment but is more commonly found as part of the microbiota of humans and animals. The bacterium is considered a common enteric pathogen; however, the pathogenesis and predisposing factors of the disease can differ among species. Therefore, specific studies are necessary for understanding the role of this pathogen, how to diagnose it and which control measures are applicable. The aim of this paper is to review the current knowledge regarding C. perfringens infections in pigs, horses and broiler chickens

Provedor de dados: 65
Autores: Polydoro,Alexandre da Silva; Natalini,Cláudio Corrêa; Linardi,Renata Lehn.
This study is the first to report the use of spinal hyperbaric opioids in horses injected through a lumbar-sacral subarachnoid catheter. The injection of hyperbaric subarachnoid morphine and methadone produced short term intense analgesia over the dermatomes of the perineal, sacral, lumbar, and thoracic areas without cardiorespiratory depression, ataxia or central nervous system excitement. The technique involves the use of 10% dextrose as a hyperbaric solvent producing an average hyperbaric solution with a specific gravity of 1030. The use of spinal hyperbaric opioids in horses can be recommended for short term moderate to severe pain management in this species.

ABSTRACT: Equine infectious anaemia (EIA) is a globally distributed disease caused by a lentivirus. EIA is a notifiable disease that should be reported to the Official Veterinary Service (SVO). Outbreaks are controlled by sacrificing the EIA-positive animals. The study analysed the prevalence of EIA in 165 Equidae seized on public roads in the municipality of Petrópolis, Rio de Janeiro, Brazil, from 2015 to 2018. After the seizure and identification of the Equidae, blood was collected to diagnose EIA. A prevalence of 11.8% was observed among the Equidae seized, and the main risk factor was the region of seizure. A kernel-smoothed map showed areas with the highest density of EIA-positive Equidae in the centre and to the east of the study area. In this...
