Abstract The objective of this study was to describe the morphology and morphometry of saggitta otoliths of Polydactylus virginicus, Menticirrhus cuiaranensis and Conodon nobilis in a tropical environment. Fishes were caught with rod and reel in competitive fishing events promoted in 2014-2015 along the coast of Sergipe. A total of 174 pairs of sagitta otoliths of P. virginicus, 181 of M. cuiaranensis and 77 of C. nobilis was extracted. In general, the sagitta otoliths of all three species analyzed here presented different morphology and shape indices. The permutational multivariate analysis of variance (PERMANOVA) demonstrated significant differences among species and ontogenetic phases within each species using morphometry and shape indices. The linear discriminant analysis (LDA) presented a 98.3% correct reclassification of the otoliths by species.

Abstract: En | Text: En | PDF: En

Biodiesel, known as a mixture of fatty acid ethyl/methyl esters, is seen as an alternative, ecofriendly, biodegradable and renewable non-fossil fuel. The use of heterogeneous catalysts for biodiesel synthesis can solve several problems associated with the homogeneous alkaline catalyzed-transesterification. Therefore, this work reports the evaluation of the commercial resin Amberlyst A26OH, a strong anion exchange resin, as a heterogeneous catalyst for the batch transesterification of refined palm olein with ethanol. It was studied the effects of the main operational parameters, considering the molar ratio of the reaction mixture (MRRM), namely the molar ratio of ethanol to olein taking into account only the ethanol added to the reaction system, and the total molar ratio (TMR), in this case considering also the amount of ethanol carried by the resin after its pretreatment. It was determined an optimal range of operational conditions by response surface methodology, guaranteeing conversion to ethyl esters higher than 96% with a catalyst amount corresponding to a range from 10.4 to 11.4% of the oil quantity, a temperature within the range of 55 to 60 ºC and a MRRM within the range from 3.5:1 to 6.0:1.

Resumo O plantio de pinus em áreas de campo natural (NG) pode alterar as formas e estoques de carbono orgânico (OC) do solo. Visando quantificar essas alterações, foram determinados os teores e estoques de OC total (TOC) e das frações particulada (POC) e associadas aos minerais (MAC) em cinco camadas, entre 0,0 e 0,4 m de profundidade, do solo sob usos com NG e plantios de pinus aos cinco (P5), 16 (P16) e 21 (P21) anos. O estudo foi realizado em áreas de Cambissolo Húmico na região do planalto sul de Santa Catarina. O teor de TOC, nas diferentes camadas e usos, variou entre 15,0 e 44,5 g kg-1 e seu estoque, na soma das camadas, entre 86 e 144 Mg ha-1. O teor de POC variou entre 2,1 a 23,2 g kg-1 e seu estoque, entre 7,4 e 21,8 Mg ha-1, enquanto o teor de MAC variou entre 12,2 e 23,7 g kg-1 e seu estoque, entre 79 e 122 Mg ha-1. Em geral, os teores e estoques de TOC e das frações MAC e POC do solo aumentam com a idade dos plantios de pinus até 21 anos. Os teores de TOC e POC e o estoque dessa fração, em geral diminuem com a profundidade do solo sob NG e P5 e P21, mas o teor de MAC e os estoques dessa fração e do TOC geralmente não variam entre as camadas até 0,40 m de profundidade.

Abstract Pine plantations on former natural grassland (NG) areas can change the forms and stocks of organic carbon (OC) in the soil. To quantify these changes, the contents and stocks of the total OC (TOC), consisting of particulate OC (POC) and the mineral-associated OC (MAC) fractions, were determined in five layers, at depths between 0.0 and 0.40 m, in soil under NG and pine plantations aged five (P5), 16 (P16) and 21 (P21) years. The study was carried out in areas of Cambissolo Húmico, dystrophic, on the southern plateau of Santa Catarina state. The TOC content in the different layers and under different land uses ranged from 15.0 to 44.5 g kg-1 and the TOC stock, in all layers together, from 86 to 144 Mg ha-1. The POC content varied from 2.1 to 23.2 g kg-1 and the POC stock from 7.4 to 21.8 Mg ha-1, while the MAC content varied between 12.2 and 23.7 g kg-1 and MAC stock between 79 and 122 Mg ha-1. In general, the TOC stocks and contents and MAC and POC fractions in the soil increase with the age of the pine plantations up to 21 years. The TOC and POC contents and POC stock usually decrease with depth under NG, P5 and P21, whereas the MAC content and MAC and TOC stocks generally remain unchanged in layers to a depth of 0.40 m.

RESUMO No arroz, o uso da bactéria Azospirillum brasilense tem se mostrado de grande utilidade para a cultura, podendo incrementar a produtividade final da mesma ou ainda, reduzir a necessidade de nitrogênio em cobertura. Recentemente notou-se que há outros reguladores que desempenham outras funções, como o thidiazuron (TDZ), uma substância de efeito citocinínico que se mostrou capaz de aumentar significativamente a produtividade do arroz de terras altas. Desse modo, o presente trabalho objetivou verificar o efeito da interação entre a aplicação foliar de A. brasilense e de doses do thidiazuron aplicadas por ocasião do perfilhamento das plantas sobre os aspectos produtivos e produtividade da cultura. O experimento foi realizado nos anos agrícolas de 2015/16 e 2016/17, na Fazenda de Ensino, Pesquisa e Extensão pertencente à Faculdade de Engenharia de Ilha Solteira - UNESP, situada no município de Selvíria-MS. Utilizou-se o delineamento experimental de blocos ao acaso, com esquema fatorial 2 x 4 com quatro repetições, cujos tratamentos foram a combinação entre a presença ou ausência da aplicação foliar de A. brasilense com doses de TDZ (0; 0,5; 1,0 e 1,5 g ha-1) aplicadas no arroz de terras altas cultivar BRS Esmeralda. Com base nos resultados obtidos para altura de plantas, número de panículas por metro quadrado, número total de grãos e fertilidade de espiguetas, massa de 100 grãos e produtividade de grãos, chegou-se à conclusão de que, nos dois anos agrícolas observados, não houve interação e efeitos individuais da aplicação da bactéria via foliar, e das doses de TDZ utilizadas por ocasião do perfilhamento na cultivar BRS Esmeralda.

ABSTRACT In rice, the use of the bacterium Azospirillum brasilense has shown to be very useful for the crop, being able to increase the final productivity of the same or reduce the need for nitrogen in topdressing. It has recently been noted that there are other regulators that perform other functions, such as thidiazuron (TDZ), a cytokinin-like substance that has been shown to significantly increase upland rice productivity. Thus, the present work aimed to verify the effect of the interaction between the foliar application of A. brasilense and thidiazuron doses applied at the occasion of the tillering of the plants on the productive aspects and crop productivity. The experiment was carried out in the agricultural years of 2015/16 and 2016/17, at the UNESP Teaching, Research and Extension Farm belonging to the Engineering Faculty of Ilha Solteira - UNESP, located in the municipality of Selvíria, MS. The experimental design was a randomized complete block design with a 2 x 4 factorial scheme with four replicates. The treatments were the combination of the presence or absence of A. brasilense foliar application with doses of TDZ (0, 0.5, 1.0 and 1.5 g ha-1) applied to upland rice cultivar BRS Esmeralda. Based on the results obtained for plant height, number of panicles per square meter, total number of grains and fertility of spikelets, mass of 100 grains and grain yield, it was concluded that, in the two agricultural years observed, there were no interaction and individual effects of the foliar application of the bacteria, and of the TDZ doses used at the time of tillering in the BRS Esmeralda cultivar.

ABSTRACT Microalgae oil of the species Chlorella protothecoides was obtained via a donation of the Soley Biotechnology Institute (SOLEYBIO) and characterized according to the fatty acid profile. Ethylic biodiesel was prepared using methods adapted by the research group. Analysis of acidity, water content, and density and viscosity temperature dependence (293.15 K to 368.15 K) were performed for the oil and ethylic biodiesel. The biofuel was characterized in terms of its flash and cloud points, heat capacity and cetane number. The properties studied were compared with conventional vegetable oils and biodiesel, presenting little differences and demonstrating the high viability of biodiesel from microalgae oil.

Resumo Como ações pessoais, aparentemente caóticas, podem gerar os imensos sistemas de interações em que vivemos? Neste artigo, buscamos responder a esta pergunta sugerindo que há um papel para as cidades, na forma de coordenar nossas ações. Investigamos esse processo explorando um conceito particular: a “entropia” ou como sistemas lidam com a incerteza e imprevisibilidade na transição de ações individuais para sistemas de ação. Examinando as condições de (i) as ações como dependentes da informação em seu ambiente e de (ii) a cidade como ambiente de informação, propomos que (iii) a cidade produz diferenças na probabilidade de que certas interações venham a ser realizadas. Investigamos este processo através de simulações de diferentes cenários, de modo a identificar o espaço como uma condição necessária, mas não suficiente, para reduzir entropia social. Finalmente, sugerimos que os estados e flutuações da entropia são uma parte vital da reprodução social, e revelam profundas conexões entre sistemas sociais, informacionais e espaciais.

Abstract How can seemingly chaotic personal acts create the coherent systems of interaction that surround us? In this paper, we attempt to answer this key question by suggesting the role for cities on how we coordinate seemingly chaotic decisions. We look into these elementary processes exploring a particular concept: “social entropy”, or how social systems deal with uncertainty and unpredictability in the transition from individual actions to systems of interaction. We examine the following conditions: (i) actions rely on informational differences latent in their environments, (ii) the city itself is an information environment to actions, and we propose that (iii) space becomes a form of creating differences in the probabilities of interaction. We investigate this process through simulations of distinct material scenarios to find that space is a necessary but not sufficient condition for the reduction of entropy. Finally, we suggest that states and fluctuations of entropy are a vital part of social reproduction, and reveal a deep connection between social, informational and spatial systems.

ABSTRACT Hypericum species, Hypericaceae, are recognized as a source of therapeutical agents. Purified fractions and isolated compounds have been shown antimicrobial activity. As the indiscriminate use of antifungals and the increase of infections caused by emerging species are leading to the search of new alternative treatments, the aim of this study was to continue the study with Hypericum carinatum Griseb. lipophilic fraction, rich in phloroglucinol derivatives, investigating the effect of its association with fluconazole against emerging yeasts (Candida krusei, C. famata, C. parapsilosis and Cryptococcus neoformans). The synergistic activity between H. carinatum lipophilic fraction and fluconazole was assessed by two methodologies for multiple dose–response analysis: checkerboard and isobologram. Regarding synergistic experiments, the effect of the association was higher than the effect of fluconazole alone against Candida krusei and C. famata isolates (MIC fluconazole decreased about eight and four folds, respectively), suggesting that, somehow, H. carinatum lipophilic fraction compounds are facilitating the action of this drug. On the other hand, when tested against Cryptococcus neoformans and C. parapsilosis, fluconazole showed better results than the association. Thus, against Candida krusei and C. famata, the lipophilic fraction of H. carinatum was able to reduce the MIC values of fluconazole and could be considered as a potential alternative to be used against emerging yeast species.

Resumo: O objetivo deste trabalho foi avaliar o efeito de cultivos consorciados entre milho e forrageiras tropicais, em diferentes alturas de corte, sobre a produção de silagem, a interceptação luminosa, a eficiência de uso da terra, os fatores de competição do consórcio e a produção da pastagem. Foram avaliados, nas safras 2010/2011 e 2011/2012, duas modalidades de cultivo no verão/outono - monocultivo de milho com rebrota do banco de sementes de capim-braquiária (Urochloa decumbens) e milho consorciado com capim-marandu (U. brizantha 'Marandu') -, em arranjo fatorial com duas alturas de corte para ensilagem - 0,20 e 0,45 m. Após a colheita do milho para ensilagem, as forragens foram pastejadas por cordeiros semi-confinados, no inverno/primavera. O monocultivo do milho e a altura de corte a 0,45 m reduziram a produtividade de matéria seca para ensilagem. O milho consorciado com capim-marandu melhorou a eficiência de uso da terra de 13 para 31%, comparado ao monocultivo do milho, com relação de equivalência de uso da terra maior que 1. O capim-marandu apresentou maior interceptação luminosa que o capim-braquiária, ao longo do período de consórcio com o milho, e proporcionou maior produção de forragem para o pastejo pelos cordeiros durante o inverno/primavera. O milho consorciado com capim-marandu, comparado ao monocultivo do milho, principalmente na altura de corte de 0,45 m, é uma opção viável para aumentar a produção de silagem e pastagem, bem como a eficiência de uso da terra em sistema de integração lavoura-pecuária.

Abstract: The objective of this work was to evaluate the effect of intercropping systems between corn and tropical forages, at different cutting heights, on silage production, light interception, land use efficiency, intercropping competition factors, and pasture production. In the 2010/2011 and 2011/2012 crop seasons, two cultivation modalities were evaluated in the summer/autumn - monocropped corn with residual regrowth of signal grass (Urochloa decumbens) from the soil seed bank and corn intercropped with palisade grass (U. brizantha 'Marandu') -, in a factorial arrangement with two cutting heights for silage production - 0.20 and 0.45 m. After corn silage harvest, the forages were grazed by lambs in a semi-feedlot system, in the winter/spring. Monocropped corn and 0.45-m cutting height both reduced dry matter yield for silage. Corn intercropped with palisade grass improved land use efficiency from 13 to 31% compared with monocropped crop, with land equivalent ratio greater than 1. Palisade grass showed higher light interception than signal grass over the intercrop period with corn and provided greater forage yield for lambs to graze during winter/spring. Corn intercropped with palisade grass, compared with monocropped corn, especially at the cutting height of 0.45 m, is a viable option for improving silage and pasture production, as well as land use efficiency in the integrated crop-livestock system.

Resumo Objetivo: Analisar as variáveis demográficas e clínicas associadas à diminuição da qualidade de vida em uma grande coorte brasileira de pacientes com espondiloartrite (EpA). Métodos: Foi aplicado um protocolo de pesquisa único a 1.465 pacientes brasileiros classificados como tendo EpA de acordo com os critérios do European Spondyloarthropaties Study Group (ESSG), atendidos em 29 centros de referência em reumatologia do Brasil. Foram registradas as variáveis clínicas e demográficas. A qualidade de vida foi analisada por meio do questionário Ankylosing Spondylitis Quality of Life (ASQoL). Resultados: A pontuação média do ASQoL foi de 7,74 (+ 5,39). Ao analisar doenças específicas no grupo de EpA, as pontuações do ASQoL não apresentaram diferença estatisticamente significativa. Os dados demográficos mostraram piores escores de ASQoL associados ao gênero feminino (p = 0,014) e etnia negra (p < 0,001). Quanto aos sintomas clínicos, a dor na região glútea (p = 0,032), a dor cervical (p < 0,001) e a dor no quadril (p = 0,001), estiveram estatisticamente associadas a piores escores no ASQoL. O uso contínuo de fármacos anti-inflamatórios não esteroides (p < 0,001) e agentes biológicos (p = 0,044) esteve associado a escores mais elevados de ASQoL, enquanto outros medicamentos não interferiram nos escores do ASQoL. Conclusão: Nesta grande série de pacientes com EpA, o sexo feminino e a etnia negra, bem como sintomas predominantemente axiais, estiveram associados a uma qualidade de vida reduzida.

Abstract Objective: To analyze quality of life and demographic and clinical variables associated to its impairment in a large Brazilian cohort of patients with spondyloarthritis (SpA). Methods: A common protocol of investigation was applied to 1465 Brazilian patients classified as SpA according to the European Spondyloarthropaties Study Group (ESSG) criteria, attended at 29 reference centers for Rheumatology in Brazil. Clinical and demographic variables were recorded. Quality of life was analyzed through the Ankylosing Spondylitis Quality of Life (ASQoL) questionnaire. Results: The mean ASQoL score was 7.74 (± 5.39). When analyzing the specific diseases in the SpA group, the ASQoL scores did not present statistical significance. Demographic data showed worse scores of ASQoL associated with female gender (p = 0.014) and African-Brazilian ethnicity (p < 0.001). Regarding clinical symptoms, buttock pain (p = 0.032), cervical pain (p < 0.001) and hip pain (p = 0.001), were statistically associated with worse scores of ASQoL. Continuous use of nonsteroidal anti-inflammatory drugs (p < 0.001) and biologic agents (p = 0.044) were associated with higher scores of ASQoL, while the other medications did not interfere with the ASQoL scores. Conclusion: In this large series of patients with SpA, female gender and African-Brazilian ethnicity, as well as predominant axial symptoms, were associated with impaired quality of life.

Resumo Se como escreve Weber, todo o conhecimento é objetivo na medida em que envolve interesses de pesquisadores e agências nos questionamos nesse texto sobre, quando falamos nos arroios Pampa e Luiz Rau, aquilo que têm sido pesquisado sobre esses dois arroios. Desta feita, além de colocar em evidência o que têm despertado o interesse, seu mérito reside em apontar algumas lacunas e campos profícuos de estudo que vão para além das ciências duras. Esse estudo se caracteriza, portanto, por um estudo bibliográfico e ensaístico que busca através da antropologia ciência pensar os limites e avanços que se obteve nos últimos anos nesse estudos e seu impacto social.

If, like Weber writes, every knowledge is objective in terms of evolving the interests of researchers and the agencies, in this article, we investigate that, which has been researched about two streams: Pampa and Luiz Rau. In doing so, in addition to highlighting what has caught the researchers' attention, this paper manages to point out a few gaps and fruitful fields of study which extend beyond the hard sciences. This study is, therefore, characterized as an essay review paper that sets out to use anthropology of science to think about the limitations and advances the studies about the two streams have achieved, as well as their social impact.

Abstract Phase equilibria of the reaction components are essential data for the design and process operations of biodiesel production. Despite their importance for the production of ethylic biodiesel, the reaction mixture, reactant (oil and ethanol) and the product (fatty acid ethyl esters) up to now have received less attention than the corresponding systems formed during the separation and purification phases of biodiesel production using ethanol. In this work, new experimental measurements were performed for the liquid-liquid equilibrium (LLE) of the system containing vegetable oil (sunflower oil and canola oil) + ethylic biodiesel of refined vegetable oil + anhydrous ethanol at 303.15 and at 323.15 K and the system containing refined palm oil + ethylic biodiesel of refined palm oil + ethanol at 318.15 K. The experimental data were successfully correlated by the nonrandom two-liquid (NRTL) model; the average deviations between calculated and experimental data were smaller than 1.00%.

Objetivo Avaliar os resultados da aplicação do Índice de Atividade de Doença da Espondilite Anquilosante de Bath (BASDAI) numa série de pacientes brasileiros com EpA e estabelecer suas correlações com as variáveis específicas do grupo. Métodos Um protocolo comum de investigação foi prospectivamente aplicado em 1.492 pacientes brasileiros classificados como EpA pelos critérios do Grupo Europeu de Estudo das Espondiloartropatias (ESSG), acompanhados em 29 centros de referência em reumatologia no Brasil. Variáveis clínicas, demográficas e índices de doença foram colhidos. Os valores totais do BASDAI foram comparados com a presença das diferentes variáveis. Resultados O valor médio do BASDAI foi de 4,20 ± 2,38. Os escores médios do BASDAI foram mais elevados nos pacientes com forma clínica combinada, comparado às formas axiais e periféricas isoladas, nos pacientes do sexo feminino e nos sedentários. Com relação ao componente axial, valores mais altos do BASDAI estiveram significativamente associados à lombalgia inflamatória, à dor alternante em nádegas, à dor cervical e ao acometimento de coxofemorais. Houve associação estatística entre os valores do BASDAI e o comprometimento periférico, relacionado ao número de articulações inflamadas, tanto dos membros inferiores quanto dos membros superiores, e às entesites. A positividade do HLA-B27 e a presença de manifestações extra-articulares não estiveram correlacionadas com os valores médios do BASDAI. Valores mais baixos do BASDAI estiveram associados ao uso de agentes biológicos (p < 0,001). Conclusão Nesta série heterogênea de pacientes brasileiros com EpA, o BASDAI conseguiu demonstrar “atividade de doença” tanto nos pacientes com acometimento axial quanto naqueles com envolvimento periférico.

Objective To analyze the results of the application of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) in a large series of Brazilian patients with the diagnosis of SpA and establish its correlations with specific variables into the group. Methods A common protocol of investigation was prospectively applied to 1492 Brazilian patients classified as SpA according to the European Spondyoarthropathies Study Group (ESSG), attended at 29 referral centers of Rheumatology in Brazil. Clinical and demographic variables, and disease indices (BASDAI, Basfi, Basri, Mases, ASQol) were applied. The total values of BASDAI were compared to the presence of the different variables. Results The mean score of BASDAI was 4.20 ± 2.38. The mean scores of BASDAI were higher in patients with the combined (axial + peripheral + entheseal) (4.54 ± 2.38) clinical presentation, compared to the pure axial (3.78 ± 2.27) or pure peripheral (4.00 ± 2.38) clinical presentations (P < 0.001). BASDAI also presented higher scores associated with the female gender (P < 0.001) and patients who did not practice exercises (P < 0.001). Regarding the axial component, higher values of BASDAI were significantly associated with inflammatory low back pain (P < 0.049), alternating buttock pain (P < 0.001), cervical pain (P < 0.001) and hip involvement (P < 0.001). There was also statistical association between BASDAI scores and the peripheral involvement, related to the lower (P = 0.004) and upper limbs (P = 0.025). The presence of enthesitis was also associated to higher scores of BASDAI (P = 0.040). Positive HLA-B27 and the presence of cutaneous psoriasis, inflammatory bowel disease, uveitis and urethritis were not correlated with the mean scores of BASDAI. Lower scores of BASDAI were associated with the use of biologic agents (P < 0.001). Conclusion In this heterogeneous Brazilian series of SpA patients, BASDAI was able to demonstrate “disease activity” in patients with axial as well as peripheral disease.

Cinco vacas da raça Holandesa foram distribuídas em quadrado latino 5x5 com o objetivo de se avaliar o efeito de níveis de substituição do grão seco de milho (GSM) pela silagem de grãos úmidos de milho (SGUM) sobre consumo, digestibilidade total dos nutrientes e glicose plasmática, o que constituiu os tratamentos: 1) 100% GSM; 2) 75% GSM e 25% SGUM; 3) 50% GSM e 50% SGUM; 4) 25% GSM e 75% SGUM; 5) 100% SGUM. O período experimental durou 70 dias, divididos em cinco fases de 14 dias. A digestibilidade foi obtida utilizando-se óxido crômico (Cr2O3) como indicador. Foram colhidas amostras fecais duas vezes por dia, bem como amostras de sangue no último dia dos períodos, antes da primeira refeição (zero hora), duas, quatro, seis e 12 horas após a refeição. Não houve efeito (P>0,05) sobre o consumo de matéria seca (MS), fibra em detergente neutro (FDN), fibra em detergente ácido (FDA) e amido. A digestibilidade aparente total da MS, a proteína bruta (PB), a FDN e a FDA não foram afetadas (P>0,05), assim como a concentração de glicose plasmática. Houve efeito linear decrescente (P<0,05) para consumo de PB e linear crescente (P<0,05) para digestibilidade do amido, à medida que se aumentou a inclusão de SGUM.

Five Holstein cows were distributed in a 5x5 latin square design to assess the effect of replacement levels of dry ground corn grain (DGCG) by high moisture corn silage (HMCS) on intake, total nutrient digestibility and plasma glucose, according to the following treatments: 1) 100% DGCG; 2) 75% DGCG and 25% HMCS; 3) 50% DGCG and 50% HMCS; 4) 25% DGCG and 75% HMCS; 5) 100% HMCS. The experiment lasted 70 days, divided into five phases of 14 days each. The digestibility was obtained using chromic oxide (Cr2O3) as the indicator. Fecal samples were collected twice daily and blood samples were collected on the last day of each period before the first meal (0h) and 2h, 4h, 6h and 12h after the meal. There was no effect (P>0.05) on the intake of dry matter (DM), neutral detergent fiber (NDF), acid detergent fiber (ADF) and starch. The total apparent digestibility of DM, crude protein (CP), NDF and ADF were not affected (P>0.05) by the treatments, as well as the plasma glucose concentration. However, there was a decreased linear effect (P<0.05) for the protein intake and increased linear effect (P<0.05) for starch digestibility, as the level of HMCS was increased in the diets.

Este estudo objetivou comparar a concentração de fungos viáveis, especialmente do gênero Aspergillus, no trato respiratório de equinos estabulados com e sem obstrução recorrente das vias aéreas (ORVA). Trinta e dois equinos provenientes de quatro centros de treinamento equestre do Brasil foram incluídos no estudo. Os animais foram submetidos a exame clínico e coleta de amostra respiratória, sendo categorizados em dois grupos: sadios e ORVA. Os lavados traqueobrônquicos obtidos foram avaliados por exame micológico direto e cultivo quantitativo. Ao todo, 18 equinos saudáveis e 14 com ORVA foram estudados. Fungos foram mais frequentemente detectados em amostras do grupo ORVA em comparação com o grupo controle, tanto no exame micológico direto (P<0,0001) e cultivo quantitativo (P<0,0001) quanto na concentração de unidades formadoras de colônias (UFC) de Aspergillus spp. isolada em cultivo (p=0,001). Equinos com ORVA têm maior concentração de propágulos fúngicos no trato respiratório em comparação com animais sadios. As implicações desses achados na patogenia da ORVA merecem maior atenção e investigação.

This study aims to compare the concentration of viable fungi, especially those of the genus Aspergillus in the respiratory tract of stabled horses with and without Recurrent Airway Obstruction (RAO). Thirty two housed horses from four equestrian centers in Brazil were included in the study. These animals were submitted to clinical examination and to a respiratory sample collection. They were categorized into two groups: healthy and RAO-affected horses. Samples obtained by tracheobronchial washes were evaluated for fungal microscopy, quantitative culture and Aspergillus spp. quantification. Eighteen healthy and 14 RAO-affected horses were studied. Fungi were more frequently recovered in the RAO group, in comparison to controls, for both fungal microscopy (P<0.0001), fungal culture (P<0.0001) and Aspergillus spp. quantitative culture (p=0.001). In conclusion, horses with RAO have significantly higher fungal load in the respiratory tract in comparison to healthy horses. The implications of these findings in terms of the pathogenesis of RAO deserve additional investigation.
