Com o objetivo de se conhecer a situação epidemiológica da AIE em haras no Estado de Minas Gerais foi estimada a prevalência em sete regiões do Estado e realizada a identificação de possíveis fatores de risco. Trata-se da segunda etapa de um estudo já iniciado com a caracterização epidemiológica da enfermidade em animais de serviço. Foram amostrados 7742 equídeos pertencentes a 717 haras, distribuídos em sete estratos regionais. O diagnóstico laboratorial foi feito em série, sendo realizado o teste ELISA como triagem e a Imunodifusão em Gel Ágar (IDGA) como teste confirmatório. A prevalência encontrada foi de 0,44% [intervalo de confiança (IC) 95% = 0,00 - 0,871] haras positivos e de 0,07% [IC= 0 - 0,251] animais positivos para a AIE. Os animais de haras apresentaram menor prevalência de AIE do que a que foi previamente estimada para animas de serviço, porque provavelmente o valor zootécnico e a necessidade de emissão de guia de trânsito para participação em eventos controlados levam à maior preocupação em promover o saneamento da propriedade com exames periódicos e sacrifício dos animais positivos. Os eqüídeos de haras também transitam mais e por isso estão sujeitos a maior controle dos órgãos oficiais de defesa sanitária. As maiores prevalências foram encontradas nos estratos 1 (messoregiões Norte/Nordeste de Minas), com 0,34% e 2 (Vale do Mucuri/Jequitinhonha) com 0,72%. O estrato 7 (Campo das Vertentes e Zona da Mata) apresentou prevalência de 0,08% e nas demais regiões não foi encontrado nenhum animal positivo. Este estudo demonstra que a prevalência da AIE em haras de Minas Gerais é muito baixa e que o risco de ocorrência da doença na região norte é mais alto que no centro e sul do estado. _________________________________________________________________________________ ABSTRACT / Horse breeding is expanding and, given the fact that it is a transmissible, incurable disease, Equine Infectious Anaemia (EIA), or swamp fever, hampers its development. With a view to determining the incidence of EIA, a survey was carried out at horse farms in the State of Minas Gerais, Brazil, in order to estimate prevalence and identifying potential risk factors. This was the second stage of an on-going study on the epidemiology of the disease, that started with horses used for animal traction. A sample of 7,742 horses was examined from 717 horse farms in seven regions within the state. Laboratory tests were carried out in series using ELISA tests for screening and agar gel immunodiffusion tests to confirm the diagnosis. The prevalence was estimated at 0.44% [confidence interval (CI) 95% = 0.00 – 0.871] for farms testing positive and 0.07% [CI = 0 – 0.251] for horses. Low incidence horse farms are likely to be explained by the higher zootechnical value of stable-bred animals, compliance with the slaughter of test-positive animals, in order to remain disease-free. Stable-bred horses move more frequently and are thus more subject to compulsory testing, compared to working animals, for which the prevalence was previously estimated at higher rates. Greater prevalence among stable-bred animals was recorded in regions 1 (North/Northeast of Minas Gerais) at 0.34% and 2 (Vale do Mucuri/Jequitinhonha) at 0.72%. Region 7 (Campo das Vertentes & Zona da Mata) showed a prevalence of 0.08% while no animals tested positive in the remaining regions. This study demonstrated that the prevalence of equine infectious anaemia in stable-horses is low and that the northern region has higher disease risk compared to the centre and south of Minas Gerais.

Notre travail aborde les milieux de cour italiens et français au travers des savoirs et des pratiques équestres répandus depuis le milieu du XVe au milieu du XVIIe siècle. A cette époque, le cheval est à la fois un élément essentiel de l'économie curiale, un véhicule du prestige princier, et un moyen d'affirmation sociale. La première partie de la thèse ("L'invention des sources") invite à découvrir les sources relatives à l'organisation des institutions équestres pour gentilshommes. Les informations concernant les spécialistes du cheval et les équidés qu'abrite la cour sont abondantes, ainsi que le montre la deuxième partie ("Les cavaliers et leurs chevaux dans les cours de la Renaissance"). La troisième partie traite de "L'économie équestre en milieu curial", ou des stratégies et des moyens mis en place par la cour pour se pourvoir en équidés que ce soit en matière de défense, loisirs ou tâches quotidiennes. La dernière partie intitulée "Mobilité et transferts" porte sur la circulation des modèles, des compétences des pratiques équestres en milieu curial. On tend à situer le début du développement de l'art équestre curial en Italie à la Renaissance, vers la fin du XVe siècle, quand les Français l'auraient "découvert" et "importé" au-delà des Alpes. Or, le modèle équestre se développant à la Renaissance, loin d'être le fruit de l'importation d'un ensemble de pratiques et de valeurs immuables, s'étoffe en circulant au gré des échanges, lors des déplacements des spécialistes du cheval, des aspirants écuyers et des membres des maisons princières. / Our thesis approaches the history of Italian and French princely courts through a survey of horsemen's theories and practices from the second half of the XVth century to the 1650s. At that time, horses are an essential element of curial economy, a medium of princely prestige and a mean of social advancement. The first part -"The invention of sources"- invites to discover the sources relating to the equestrian curial institutions (Stables and Studs), to the exchanges between princely households, or to the way equestrian academies for the nobility are run. These sources provide quite a lot of data concerning horse specialists, as we explain in the second part entitled "Horsemen and their Horses in Renaissance Princely Courts". The third part, concerning "Curial economy", examines how a princely household provide itself with the horses it needs for its defence, its leisure activities or its daily routine. The last part -"Mobility and Transfers"- analyzes not only horsemen's mobility and how their know-how spreads, but also the diffusion of cultural models, and of fashionable items of equipment for horses and riders, from court to court, countrywide or abroad. Usually, the development of the equestrian art is considered as a product of the end of the XVth century, when it would have been "discovered" and "imported" from Italy by the French. Nevertheless, Renaissance equestrian models are far from being a fruit of a massive importation of theories, practices and immutable values. They take shape thanks to the exchanges, and to the mobility of horse specialists, young horsemen-to-be travelling to complete their equestrian education, and members of the princely courts
