A retrospective study of equine skin diseases diagnosed in the Laboratório Regional de Diagnóstico, Faculdade de Veterinária, Universidade Federal de Pelotas was conducted between 1978 and 2013. The necropsy and biopsy protocols for horses received for diagnosis were reviewed to determine the prevalence of dermatopathies in southern Brazil. The most prevalent skin diseases in decreasing order were: sarcoid [234/710 (32.9%)], exuberant granulation tissue [81/710 (11.4%)], pythiosis [67/710 (9.4%)], squamous cell carcinoma [55/710 (7.7%)], papillomatosis [33/710 (4.6%)] and habronemiasis [30/710 (4.2%)]. Other skin lesions accounted for 25.3% of all cases studied. The Crioulo breed was the most prevalent [310/710 (43.6%)]. Horses aged between 2-5 years old...

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...

ABSTRACT: Cryptococcus gattii is often associated with pulmonary and systemic infections in humans and animals. In this research we report a case of nasopharyngeal cryptococoma caused by C. gatti in an equine. A 10-year-old mare presented a mass obstructing the oropharynx. Macroscopically the mass was asymmetric, and was attached to the ethmoidal sinuses and obstructed the oropharynx. Histopathological examination of the mass revealed multiple yeast cells ranging from spherical to oval, 4-8μm in diameter, with some of them showing narrow base polar budding. Cryptococcus gattii growth in mycological culture (Sabouraud Dextrose Agar) and was L-canavanine-glycine-bromothymol blue Agar positive. The molecular identification confirmed the isolate as C. gattii...

ABSTRACT The objective was to evaluate the accuracy of six body weight (BW) estimating methods in Mangalarga Marchador horses (MM) (n = 318): method A - tape placements at three different positions around the thoracic girth; B - Crevat and Quetelec's formula; C - Hall's formula; D - Hintz and Griffiths’ table; E - Santos’ table; and F - Cintra's formula. For additional analyses, gender, age, and gestational stage were considered. Estimated average BW was compared to the actual scale weight by the paired T test, mean predicted error, and determination coefficient. In the general population, methods A (position 3), B, and C estimated BW that were different from that of the scale. Method A, at positions 1 and 2, was more accurate in predicting the scale...

YAMAGUCHI, Toshiro; ENDO, Yoshiro; NAMBO, Yasuo; SATO, Fumio; SASAKI, Naoki; YAMADA, Kazutaka; 南保, 泰雄; 佐々木, 直樹; 山田, 一孝.

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<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...

Evaluation of the Cranial Cruciate Ligament Repair System® in Surgery for Laryngeal Hemiplegia in Heavy Draft Horses

SASAKI, Naoki; FUKUNAKA, Morito; YAMADA, Haruo; SENBA, Hiroyuki; HIGUCHI, Tohru; 佐々木, 直樹.

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.

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<0.01). The canine cranial cruciate ligament repair system was revealed to be a good surgical procedure for laryngeal hemiplegia in heavy draft horses.

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...

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...

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...

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.
