Abstract: infection with bacteria of the genus brucella results in major economic and political impact by causing reproductive diseases in a significant number of domestic animal species. moreover, it has a great social significance, since many species are capable of causing human infection, with severe consequences. dissemination of knowledge on a specific disease is an essential step for its control. considering that brucellosis is still the most prevalent zoonosis in the world, information about taxonomy, clinical signs in domestic animals and humans are crucial for attempting to reduce the prevalence of this disease. the recent isolation and characterization of non-classical species of brucella indicates that a lot remains to be discovered about this genus. nevertheless, due to the social-economic importance of brucellosis, this review aims to clarify points related to taxonomy of the genus and describe the clinical relevance of infection in humans and domestic animals.

Abstract: O presente trabalho tem como objetivo avaliar a influência de diferentes sistemas de manejos, a popula o microbiana e sua atividade. Para tal, foram coletadas, em outubro de 2006 e mar o de 2007, amostras de solo na Fazenda Sereno no Município de Jaciara, Estado do Mato Grosso. Retirou-se amostras de solo na profundidade de 0-10 cm, com quatro repeti es em cinco áreas com diferentes sistemas de manejos: integra o lavoura-pecuária, lavoura de milho/soja, pastagens, vegeta o nativa e vegeta o nativa em recupera o. Para avaliar o carbono da biomassa microbiana (CBM) e a respira o microbiana (RM) foi utilizado o método do Clorofórmio Fumiga o-Incuba o (CFI). Já o qCO2 foi obtido pela rela o entre a RM e oCBM. As médias foram comparadas pelo teste de Scott-Knott a 5%. No decorrer das análises, p de-se observar que as diferentes práticas agrícolas afetam fortemente o solo causando distúrbios na comunidade microbiana que podem, por sua vez, influenciar os processosbiogeoquímicos que nele ocorrem. Os dados obtidos permitem, ainda, concluir que: nos sistemas Integra o lavoura-pecuária e pecuária a popula o microbiana é influenciada pelas épocas de coletas. Nesse trabalho, no sistema Integra o lavoura-pecuária a atividade microbiana é constante nas diferentes épocas de coleta e os diferentes sistemas de manejos influenciam a atividade metabólica dos microrganismos presentes no solo.

Abstract: the aim of this study was to characterize phytophthora isolates from black wattle (acacia mearnsii) in southern brazil, based on phenotypic traits such as morphology, mycelial growth, cultural features, sexual compatibility and pathogenicity, as well as on single strand conformation polymorphism (pcr-sscp) of rdna its-gene 5.8s region. the isolates presented sporangia with prominent papilla, irregularly sympodial sporangia, heterothalic cultures with amphigynous antheridia, presence of chlamydospore and mycelial growth at temperature above 35°c, allowing the classification of all 12 isolates as p. nicotianae. all isolates were pathogenic to black wattle, causing necrosis on stems without gum formation, with significant differences on aggressiveness (p=0.05). two populations of p. nicotianae from black wattle can be distinguished based on pcr-sscp analysis of rdna; however, this separation has no apparent correlation with phenotypic traits.

Abstract: Fish diet studies contribute to understanding resource partitioning and community trophic structure. The present paper characterizes the diet of gpeixe-cachorro h species Acestrorhynchus britskii and A. lacustris in Sobradinho reservoir, Bahia State, Brazil. Bimonthly samples (November 2006 to July 2008) were taken in the lotic, transition and lentic stretches of the reservoir, using gillnets overnight. A total of 899 A. britskii and 476 A. lacustris stomachs were analyzed, 70% of which were empty. Their content indicated the species are predominantly piscivorous, with 18 prey fish species identified. However, each prey occurred in a single month, except for Anchoviella vaillanti, recorded in 80% of months for A. bristski, andTetragonopterus chalceus in 25% for A. lacustris. The species presented high food overlap (C é = 0.992), owing to the occurrence of Actinopterygii (bits) and Actinopterygii in all months. Regarding prey fish alone, a differentiated intake and lower food overlap was detected, in the flood (C é = 0.427) and drought (C é = 0.172) seasons, in the lotic (C é = 0.434), transition (C é = 0.089) and lentic (C é = 0) stretches, and in overall overlap (C é = 0.236). The spatial and seasonal differences in the intake of different prey fish by both species suggest an opportunistic feeding habit and a competition reduction mechanism for food resources. Estudos sobre a dieta de peixes contribuem para o entendimento dapartilha de recursos e da estrutura trofica da comunidade. O presente trabalho caracteriza a dieta dos peixes-cachorro Acestrorhynchus britskii e A. lacustris no reservatorio de Sobradinho, Estado da Bahia. Coletas bimestrais noturnas (Novembro/2006 a Julho/2008) foram efetuadas nos trechos lotico, transicao e lentico do reservatorio, empregando redes de espera. Foram analisados 899 estomagos de A. britskii e 476 de A. lacustris, aproximadamente 70% dos quais se encontravam vazios. Seu conteudo evidenciou tratar-se de especies predominantemente piscivoras, com 18 peixes-presa identificados. Entretanto, cada presa ocorreu num unico mes, exceto Anchoviella vaillanti, registrada em 80% dos meses para A. bristski e Tetragonopterus chalceus em 25% deles para A. lacustris. As especies apresentaram elevada sobreposicao alimentar (C é = 0,992), pela ocorrencia de Actinopterygii (partes) e Actinopterygii nao-identificado em todos os meses. Entretanto, considerando apenas os peixespresa, foi observado consumo diferenciado e menor sobreposicao alimentar, nos periodos de cheia (C é = 0,427) e seca (C é = 0,172), nos trechos lotico (C é = 0,434

Abstract: Criatórios de avestruz têm se tornado comuns no Brasil, mas por se tratar de espécie exótica, as informa es sobre as doen as desses animais no nosso ambiente s o escassas. Um avestruz de cinco meses de idade apresentou tosse, anorexia, perda de peso, dispnéia discreta, temperatura corporal normal e morreu oito dias após o início dos sinais clínicos. Macroscopicamente foram observados nódulos múltiplos no pulm o e nos sacos aéreos. Histolopatogicamente, observou-se pneumonia granulomatosa e necrosante multifocal com hifas ramificadas e septadas intralesionais com características morfológicas de Aspergillus sp. Nos sacos aéreos, além das hifas e processo inflamatório adjacente haviam vários micélios com conidióforos na superfície interna. Foi isolado Aspergillus fumigatus dos tecidos afetados. De acordo com os achados histopatológicos e micológicos firmou-se o diagnóstico de pneumonia e aerossaculite micótica severa causada por Aspergillus fumigatus. Com base nas informa es disponíveis na literatura, esse é o primeiro caso de aspergilose em avestruz documentado no Brasil.
