A pele de tilápia está sendo utilizada em humanos e animais silvestres com feridas por queimadura demonstrando um excelente resultado. O objetivo do estudo é avaliar se a pele de tilápia utilizada como curativo oclusivo melhora o processo de cicatrização em dois equinos machos adultos da raça Mangalarga Machador, os quais apresentam feridas crônicas. A cada 7 dias as feridas eram medidas, fotografadas, biopsiadas para a análise histopatológica, limpas e o curativo de pele de tilápia trocado. O programa Image J foi utilizado para calcular a área da ferida. A pele de tilápia utilizada como curativo oclusivo parece ter um efeito positivo na cicatrização das feridas, a área diminuiu e a o aspecto clínico melhorou nos 35 dias avaliados, no entanto é necessário esperar pela cicatrização completa das feridas. Em equinos, a utilização de curativo de pele de tilápia parece diminuir o tempo de cicatrização e permite a redução do número de trocas de curativos de a cada dois dias para uma vez por semana. Isso implica em menos estresse e dor para o animal devido à menor manipulação e menor custo de tratamento, pois há menor quantidade de material de curativo sendo utilizado. Além disso, permite evitar a utilização de antibióticos, o que diminui o impacto ambiental e não gera resistência.  | Tilapia skin is being already use in humans and wild animals present burning wounds and showed a great result. The objective is to evaluate if tilapia skin used as an occlusive curative improves equine wound healing in two horses present chronic wound. Both animals are males, adults, both of breed Mangalarga Marchador South America. Every seven days wound we measured, photographed, biopsied for histopathological analysis, cleaned and tilapia curative was changed. Image J software was used to measure wound area. Tilapia skin as an occlusive biological factor seemed to improve healing process, wounds present an area reduction and clinical improvement during 35 days treatment, even though is still waiting for complete wound healing. In equine tilapia skin curative seemed to speed up healing process and allowed reduced curative change from every two days to once a week. This implies in decrease animal´s stress, less pain and treatment cost reduction since we used less bandage amount. Beside that tilapia skin industrial waste. Furthermore, it allowed avoid using antibiotics, which reduces environment pollution and there´s no antibiotic resistance issues.

O presente trabalho avaliou a viabilidade econômica do projeto de produção industrial de dietas completas para aespécie equina, utilizando três fontes de fibra (rolão de milho ou capim elefante desidratado ou feno de Tifton 85)submetidas a dois tipos de tratamento térmico (peletização ou extrusão). Foram realizados o levantamento e elaboraçãode custos desde a produção agrícola do volumoso até a comercialização do produto final. Foram propostos três cenárioscomparativos: S1 – preço base da dieta completa (ingredientes fornecidos ao mesmo tempo, porém, separadamente);S2 – preço de S1 mais 10%; S3 – preço de S1 mais 20%. A Taxa Interna de Retorno (TIR) e o Valor Presente Líquido(VPL) foram os indicadores de rentabilidade. O Payback simples foi utilizado para verificar o tempo de retorno doinvestimento. Foi realizada análise de sensibilidade para identificar os itens que mais influenciaram os resultadoseconômicos. O Payback simples variou de um a seis anos. Os maiores valores de TIR (>100% a.a) e VPL foram obtidospara as dietas extrusadas no cenário 3. Apenas a dieta peletizada contendo feno de Tifton 85 no cenário 1 não foi viáveleconomicamente, apresentando TIR negativa. Os insumos compõem o item de maior oneração no processo produtivo(média de 89%). Exceto para dieta peletizada contendo feno de Tifton 85 no cenário 1, os demais projetos apresentamTIR acima da taxa média de atratividade sendo considerados viáveis economicamente. | This study evaluated the economic viability of industrial production of complete diets for equine species, using threesources of fiber (dehydrated whole corn plant, dehydrated elephant grass, or Tifton 85 hay) submitted to two typesof thermal processing (pelleting or extrusion). A survey and elaboration of costs from the agricultural production ofroughage to the commercialization of the final product was conducted. Three scenarios were compared: S1 – basalprice of complete diet (ingredients supplied together, but purchased separately); S2 – price of S1 plus 10%; S3 – priceof S1 plus 20%. Profitability indicators applied were internal rate of return (IRR) and net present value (NPV). Simplepayback was used to verify return on investment time. Sensitivity analysis was performed to identify the items thatmost influence the economic results. Simple payback ranged from one to six years. The highest values of IRR (>100%per year) and NPV were obtained for the extruded diets in scenario 3. Only the pelletized diet containing Tifton 85 hayin scenario 1 was not economically feasible, presenting negative IRR. The inputs make up the item with the greatestburden on the production process (mean 89%). Except for pelletized diet containing Tifton 85 hay in scenario 1, theother projects present IRR above the minimum attractiveness rate (MAR) and were considered economically feasible.

O vírus do Nilo Ocidental (WNV) é um flavivírus neuropatogênico transmitido por mosquito, mantido na natureza emum ciclo de transmissão zoonótica entre as aves e os mosquitos ornitofílicos, principalmente do gênero Culex. Até a décadade 1990, o WNV era considerado um arbovírus do mundo antigo, mas em 1999 surgiu nos Estados Unidos da Américae se espalhou rapidamente, tornando-se uma grande ameaça à saúde pública. O WNV se adaptou ao ciclo envolvendomosquitos e pássaros americanos e chegou à América Central e do Sul nos anos subsequentes. Em 2003, o Sistema Nacionalde Vigilância da Febre do Nilo Ocidental no Brasil foi criado com base na triagem sorológica de animais sentinelas evetores, conforme recomendado pela Organização Pan-Americana da Saúde (OPAS) e pela Organização Mundial daSaúde (OMS). Desde 2008, evidências sorológicas de infecção por WNV em equinos brasileiros têm sido relatadas e acirculação do WNV monitorada por meio de triagem sorológica de cavalos sentinelas, além da notificação de casos deencefalomielite. Os equinos são altamente suscetíveis ao WNV e surtos de doenças neurológicas geralmente precedemcasos humanos. Nesse sentido, a vigilância equina tem sido essencial para fornecer um alerta precoce às autoridades desaúde pública e animal em vários países, incluindo o Brasil. Isso demonstra a necessidade de programas de intervençãoem saúde pública e animal para alocar recursos e conscientizar os médicos veterinários sobre seu papel em processos devigilância humana que envolvam equinos. Nesta revisão, é discutida a importância da vigilância equina e dos médicosveterinários como linha de frente na vigilância humana no Brasil e no mundo, no contexto de saúde única. | West Nile virus (WNV) is a neurovirulent mosquito-borne Flavivirus that is maintained in nature by a zoonotic transmissioncycle between avian hosts and ornithophilic mosquito vectors, mostly from the Culex genus. Until the 1990s, WNV wasconsidered to be an old-world arbovirus, but in 1999, WNV emerged in the United States (US) and spread rapidly, becoming amajor threat to public health. WNV adapted to the transmission cycle involving American mosquitoes and birds and reachedCentral and South America in subsequent years. In 2003, the National West Nile Fever Surveillance System was created in Brazilbased on serological screening of animals and sentinel vectors, as recommended by the Pan American Health Organization(PAHO) and the World Health Organization (WHO). Since 2008, serological evidence of WNV infection in Brazilian horseshas been reported, and the circulation of WNV has been monitored through the regular serological screening of sentinel horsesand reporting of encephalomyelitis cases. Horses are highly susceptible to WNV infection, and outbreaks of neurologicaldisease among horses often precede human cases. In this regard, equine surveillance has been essential in providing earlywarning to public and animal health authorities in several countries, including Brazil. This demonstrates the need for animaland public health intervention programs to allocate resources to make veterinarians aware of the role they can play in thehuman surveillance processes by monitoring horses. This review discusses the importance of equine surveillance and the gapthat veterinarians can fill on the front line in human surveillance, in Brazil and worldwide, in the context of “One Health”

O objetivo desse estudo foi avaliar as anormalidades articulares observadas em equinos submetidos à artroscopia terapêutica, utilizando protocolos baseados em pontuações e correlacionando os resultados do tratamento cirúrgico com a satisfação do proprietário. Neste estudo prospectivo, foram avaliadas 126 articulações de cavalos atletas, encaminhados para artroscopia. As articulações foram pontuadas de acordo com os achados da anamnese e exame físico, exame radiográfico, exame ultrassonográfico e avaliação artroscópica. A claudicação, resposta positiva ao teste de flexão e diminuição do ângulo máximo de flexão articular foram detectados em mais de 50% das articulações. Aumento de volume dos tecidos moles, esclerose subcondral, osteólise subcondral e fragmentos osteocondrais únicos foram os achados radiográficos mais comuns. O exame ultrassonográfico revelou, com frequência, as alterações no volume e na aparência do líquido sinovial, além de irregularidades osteocondrais. O aumento da vascularização das vilosidades sinoviais, fibrilação condral, fissuras condrais e erosões superficiais da cartilagem foram os achados artroscópicos mais significativos. As abordagens diagnósticas que demonstraram maior sensibilidade e melhor correlação entre o resultado do tratamento e satisfação do proprietário foram história médica, exame ultrassonográfico e artroscópico. O protocolo de avaliação utilizado, baseado em um sistema de pontuação das anormalidades articulares observadas em cada exame, permitiu uma avaliação objetiva, ressaltando os achados mais frequentes e estabelecendo um escore de gravidade da lesão para cada articulação. | This study aimed to grade joint abnormalities in horses submitted to therapeutic arthroscopy using score-based protocols for equine joint assessment, correlated with arthroscopic treatment outcomes and owner satisfaction. In this prospective study, we evaluated 126 joints of athletic horses referred for arthroscopy. The joints were scored according to findings of medical history and physical, radiographic, ultrasonographic and arthroscopic examination. Lameness, positive response to flexion test and decreased maximum joint flexion angle were detected in more than 50% of joints. Soft tissue swelling, sclerosis, subchondral bone osteolysis and single osteochondral fragments were the most common radiographic findings. Ultrasonographic examination revealed changes in synovial fluid volume and appearance, and subchondral bone irregularities. Increased vascularity of the synovial villi, chondral fibrillation, chondral fissures and superficial cartilage erosions were the most significant arthroscopic findings. The approaches that demonstrated greater sensitivity and correlation with treatment outcome and owner satisfaction were medical history, ultrasonographic and arthroscopic examination. The scoring protocol employed to grade joint abnormalities enabled the creation of a joint score system for the objective assessment, thus determining the most frequent findings and establishing an injury severity score for each joint.

As dorsopatias são causas comuns de diminuição de desempenho em cavalos atletas de várias modalidades e a sela inadequada ou mal ajustada pode levar ao aparecimento de lesões e dor lombar. O presente trabalho avaliou a pressão que os suadores dos dois modelos de sela mais comumente utilizados em cavalos Árabes de enduro exercem sobre a região toracolombar desses animais de modo a sugerir o uso do que fosse mais adequado. Foram utilizados seis cavalos da raça Árabe, machos castrados, com peso de 390 ± 4,2 e idade 8 ± 2,1 anos, condicionados para as provas enduro de velocidade livre e dois modelos de sela, a Inglesa e a Western. Os cavalos foram submetidos ao trabalho montado em pista de areia pelo mesmo cavaleiro, experiente, que pesou 76 kg. Foi realizada a termografia antes e depois das sessões de exercício. Os dados obtidos foram analisados através de teste T pareado de Student a 5% de significância. Houve diferença de temperatura média, após o exercício, entre as áreas de contato dos suadores direito e esquerdo da sela Inglesa e da sela Western, quando comparados, sendo que a sela Inglesa apresentou maiores temperaturas. Portanto, o modelo de sela Western, que possui suadores largos, embora não seja o modelo de preferência dos cavaleiros de enduro, mostrou-se mais adequado para o trabalho de cavalos Árabes. | Dorsopathies are common causes of decreased performance in athletic horses of various modalities, and inadequate or poorly adjusted saddles can lead to the onset of injuries and low back pain. The present study, searching to find the most appropriate saddle, evaluated the pressure determined from the panels of two saddle models most commonly used in endurance Arab horse on the thoracolumbar region. For the study, six Arabian geldings were used, weighing 390 ± 4.2 and 2.1 ± age 8 years, conditioned to endurance races, and two saddle models, English and Western. The horses were submitted to the work riding on a sandy lane by the same experienced rider who weighed 76 kg. Thermography was performed before and after each exercise session. The obtained data were analyzed through Student’s paired t-test at 5% of significance. After exercise, there was a mean temperature difference between the contact areas of the right and left of the sweepers of two saddles compared, with the English saddle showing higher temperatures. Therefore, the Western saddle model, which has wider panels, despite not being a preferred model of endure riders, has proved to be more suitable for Arabian horse work.

A mineralização de estruturas anatômicas envolvidas na movimentação dos membros predispõe à claudicação e interfere no desempenho atlético. Foi admitido no Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da USP-SP um equino macho, da raça Brasileiro de Hipismo, com quatro anos de idade e histórico de claudicação leve e ligamento sesamoideo oblíquo distal mineralizado do membro torácico esquerdo, diagnosticado por exame de compra. A mineralização apresenta alta incidência em tendões, sendo em menor proporção nos ligamentos. Esse relato visa atentar à essas estruturas ao se realizar exames rotineiros de imagem, apesar de claudicação leve. O acompanhamento a longo prazo por ultrassonografia e radiografia mostrou que lesões graves de ligamentos, como no presente caso, não diminuíram a atividade atlética até o momento. | Mineralization of the anatomical structures involved in the limb movement of horses has been reported to induce lameness and interfere with athletic performance. A 4-year-old jumping horse in sport activity was reported at Veterinary Hospital of University of São Paulo, with mild lameness and a mineralized oblique distal sesamoidean ligament (ODSL) of the left forelimb, revealed by a purchase radiographic and ultrasound examination. Mineralization is more common in tendons than ligaments. This report calls for attention to these structures when performing image exams, even in mild lameness. Long-term favorable follow-up by ultrasonographic and radiographic examination showed that the severe ligament injury in this case did not decrease the athletic activity until the present day.
