Aspergillosis merupakan penyakit yang disebabkan oleh jamur Aspergillus sp. yang dapat menyerang puyuh muda secara akut dan sebagai penyakit menahun pada puyuh dewasa. Penelitian ini bertujuan untuk mengisolasi dan mengidentifikasi Aspergillus sp. pada kantung hawa puyuh (Coturnix japonica). Sampel yang digunakan dalam penelitian ini adalah 35 kantung hawa puyuh yang tidak produktif lagi (afkir) diambil secara acak. Isolasi dan identifikasi Aspergillus sp. dilakukan sesuai dengan menggunakan metode Thompson. Sampel dicuci dengan aquadest steril berisi antibiotic gentamicin selanjutnya ditanamkan pada media Sabouraud’s Dextrose Agar (SDA) kemudian diinkubasikan pada suhu kamar selama 3-7 hari. Pertumbuhan koloni Aspergillus sp. diamati morfologinya secara makroskopis dan mikroskopis. Data yang diperoleh dianalisis secara deskriptif. Hasil pemeriksaan menunjukkan bahwa Aspergillus sp. dapat diisolasi dan diidentifikasi pada 24 dari 35 sampel kantung hawa. Berdasarkan hasil penelitian dapat disimpulkan bahwa 68,57% sampel yang diperiksa positif terinfeksi Aspergillus sp. dengan persentase masing-masing spesies Aspergillus fumigatus 40%, Aspergillus flavus 25,7%, dan Aspergillus niger 17,1%.

<p>The post-harvest fungi is one of the greatest cause of various diseases. Particularly, in fungus that infects seeds, the toxic substance called aflatoxin is found. This has caused us to wonder: Has fungi been pathogenic fungi since the beginning of creation? The purpose of this research is to study: 1) The Place of Fungi in God’s Original Creation and the Origin of Pathogenic Fungi, 2) Characterization of post-harvest fungus on corn seeds, 3) Aspergillus sp.’s Structure as Proof of God’s Wonderful Original Creation and Providence, and 4) The factors that contribute to the growth of fungi in post-harvest corn seeds and our responsibility. We conclude that in the beginning, fungi were a part of God’s originally good and perfect creation. These fungi were created by God with the structure and function to support its operation in fulfilling God’s creative purpose. The complex structure of Aspergillus niger and Aspergillus flavus that infected the corn seeds showed God’s providence after the Fall. Pathogenic fungi were the result of the Fall of man into sin. Their growth is caused by the failure to give proper care to the crops. But this should not discourage us since the Bible tells us that God is continually working to restore His creation. Therefore, we are called to be stewards of His creation, to develop and preserve whatever is entrusted in our hands, including the crops for God’s glory and under His authority until He has fully renewed and restored everything.</p><p><strong>BAHASA INDONESIA ABSTRACT:</strong> Jamur pasca panen merupakan salah satu penyebab terbesar timbulnya berbagai penyakit, khususnya disebabkan oleh jamur yang menginfeksi biji-bijian dan menghasilkan substansi beracun disebut dengan aflatoksin. Keadaan ini menimbulkan pertanyaan apakah jamur patogenik ada sejak awal penciptaan? Penelitian ini bertujuan untuk mempelajari: 1) Posisi jamur patogenik di awal penciptaan dan asal mula jamur patogenik, 2) karakteristik jamur pasca panen pada biji jagung, 3) struktur <em>Aspergillus</em> sp sebagai bukti dari providensi Allah akan ciptaanNya yang sangat luar biasa, 4) faktor-faktor yang berkontribusi terhadap pertumbuhan jamur pasca panen biji jagung dan Tanggung jawab kita. Dari hasil penelitian ini disimpulkan bahwa pada mulanya, jamur merupakan bagian ciptaan Allah yang sungguh amat baik dan sempurna. Struktur yang kompleks dari <em>Aspergillus niger</em> dan <em>Aspergillus flavus </em>yang menginfeksi biji jagung menunjukkan providensi Allah setelah kejatuhan dosa. Pertumbuhan jamur patogenik merupakan gambaran kejatuhan manusia ke dalam dosa yaitu kegagalan manusia untuk memberikan pemeliharaan yang memadahi pada biji-bijian pasca panen. Namun demikian, keadaan ini tidak mematahkan semangat kita karena Alkitab mengatakan bahwa Allah masih terus bekerja untuk memulihkan ciptaanNya. Oleh karena itu, diharapkan kita semua menjadi pelayan atas ciptaanNya untuk mengembangkan dan menjaga apa yang dipercayakan kepada kita di bawah otoritasNya termasuk biji-bijian untuk memuliakan Allah hingga Dia secara penuh memperbaharui dan memulihkan segala sesuatu</p>

Birds are potential vectors of some diseases as their droppings pose public health risk and cause illness. Dust containing dry faeces after inhaling can infects humans. The prevalence of fungi from the faeces of birds in wetlands has not been previously determined. Hence, the present study was carried out to isolate and identify different fungal species present in the droppings of spot-billed pelican, Pelecanus philippensis. Among the fungal species identified Aspergillus flavus, Aspergillus niger and Aspergillus fumigatus were found to be dominating.

RESUMO A aspergilose é causada por fungos ubíquos e oportunistas do gênero Aspergillus, que liberam milhares de conídios no ar, contaminando o ambiente, sendo de extrema importância a utilização de filtros de ar e programas corretos de anti-sepsia e desinfecção para prevenção da enfermidade. Este estudo avaliou a eficácia “in vitro” dos agentes químicos, iodóforo, amônia quaternária e clorexidina, frente a isolados de Aspergillus fumigatus (8), Aspergillus niger (8), Aspergillus flavus (6) e Aspergillus terreus (1). Para o teste foram preparadas diluições sucessivas dos desinfetantes/antisépticos (log2) em caldo RPMI, e os inóculos foram ajustados até uma concentração final de 5 x 104 UFC/mL. Foi realizada a técnica de microdiluição em caldo de acordo com NCCLS M-38, adaptada para agentes químicos, com incubação das microplacas a 35° C em agitação constante. A leitura visual dos resultados foi realizada após 96 horas, e os isolados de Aspergillus spp. utilizados foram resistentes ao iodóforo nas concentrações testadas. A amônia quaternária e a clorexidina mostraram-se eficazes contra os isolados de Aspergillus spp., com exceção de um A. fumigatus e um A. terreus. Com estes resultados indica-se a utilização da amônia quaternária e da clorexidina na prevenção da aspergilose, questionando-se o uso de iodóforos para este fim.

1. Ten moulds and two yeasts were analysed for the presence of 2-polyprenylphenols, 2-polyprenyl(H2)phenols, 6-methoxy-2-polyprenylphenols, 6-methoxy-2-polyprenyl(H2)phenols, 6-methoxy-2-polyprenyl-1,4-benzoquinones, 6-methoxy-2-polyprenyl(H2)-1,4-benzoquinones, 5-demethoxyubiquinones, 5-demethoxyubiquinones(H2), ubiquinones and ubiquinones(H2). 2. The organisms were found to be of three types: (a) those that contained only ubiquinones (Aspergillus fumigatus and Penicillium brevi-compactum) or ubiquinones(H2) (Alternaria solani, Claviceps purpurae and Penicillium stipitatum); (b) those that contained 5-demethoxyubiquinones and ubiquinones (Agaricus campestris, Aspergillus niger, Phycomyces blakesleeanus, Rhodotorula glutinis and Saccharomyces cerevisiae) or 5-demethoxyubiquinones(H2) and ubiquinones(H2) (Aspergillus quadrilineatus and Neurospora crassa); (c) one that contained 2-decaprenyl(H2)phenol, 6-methoxy-2-decaprenyl(H2)phenol, 6-methoxy-2-decaprenyl(X-H2)-1,4-benzoquinone, 5-demethoxyubiquinone-10(X-H2) and ubiquinones(H2) (Aspergillus flavus). 3. Studies were made on the biosynthesis of ubiquinones and ubiquinones(H2) by Asp. flavus, Phyc. blakesleeanus and S. cerevisiae. These provided evidence that in Phyc. blakesleeanus 5-demethoxyubiquinone-9 is a precursor of ubiquinone-9 and that in S. cerevisiae 5-demethoxyubiquinone-6 is a precursor of ubiquinone-6. In addition they yielded results that may be interpreted as providing evidence that in Asp. flavus 6-methoxy-2-decaprenyl(X-H2)-1,4-benzoquinone and 5-demethoxyubiquinone-10(X-H2) are precursors of ubiquinone-10(X-H2).

A qualidade das cascas do caule de Tabebuia avellanedae Lor. ex Griseb. (Bignoniaceae), conhecida como pau d’arco roxo, largamente empregada na prática popular, foi avaliada realizando-se análise qualitativa de pesquisa para fungos. Em mercados públicos da capital maranhense foi realizada amostragem aleatória simples das bancas de venda de plantas para uso medicinal, totalizando doze bancas selecionadas. No período de setembro/2000 a fevereiro/ 2001, amostras das cascas do caule Tabebuia avellanedae, foram adquiridas, por compra, em triplicata, nessas localidades. Na análise microbiológica, fragmentos uniformes das amostras comerciais foram inoculados em placas com meios ágar Sabouraud dextrose e ágar batata, mantidas em temperatura ambiente de 5 a 7 dias. Ocorrido crescimento de colônias de fungos, realizou-se a técnica de microcultivo em lâmina, utilizando lactofenol azul de algodão como corante. A identificação das espécies de fungos foi fundamentada na morfologia macroscópica das colônias e no estudo dos órgãos vegetativos e de frutificação do fungo cultivado pela técnica de microcultivo. Foram identificados fungos Absidia ssp., Rhizopus ssp., Penicillium ssp., Aspergillus flavus, Aspergillus fumigatus e Aspergillus niger, este último presente em todas as amostras analisadas. Os resultados comprovam a má qualidade das amostras comerciais de pau d’arco roxo comercializadas em mercados de São Luís/MA; comprovando-se fungos não permitidos pela legislação vigente e literatura especializada; expondo o consumidor ao risco real de utilização de droga vegetal imprópria para o consumo, evidenciando-se, assim, a necessidade da adoção de programa de fiscalização, vigilância e controle de qualidade domaterial vegetal disponibilizado para comercialização para fins medicinais em mercados. MICROBIOLOGICAL QUALITY OF WOOD BARKS OF Tabebuia avellanedae Lor. ex Griseb. COMMERCIALIZED IN SÃO LUÍS/MARANHÃO Abstract The quality of wood barks of Tabebuia avellanedae Lor. ex Griseb. (Bignoniaceae), known as “pau d’arco roxo”, widely used in popular medicine, was evaluated by means of qualitative analysis of fungus. In public markets of the Maranhão capital it was carried through a simple random sampling of the sales banking of herbal medicinal, totaling twelve selected banking. During September/2000 to February/2001 samples of wood barks of Tabebuia avellanedae were acquired, by purchase in triplicate. In the microbiological analysis, uniform fragments of these commercial samples were inoculated in dishes with agar Sabouraud dextrose and agar potato held at room temperature from 5 to 7 days. After the growth in colonies of fungus, microcultive in lamina was made having blue lactophenol of cotton as ink. Identification of species of fungus was based on macroscopic morphology of colonies in the study of vegetative organs and of fructification ofmicrocultive cultivated fungus. Absidia ssp., Rhizopus ssp., Penicillium ssp., Aspergillus flavus, Aspergillus fumigatus e Aspergillus niger were identified, being this last one present in all analyzed samples. The results proved the bad quality of the samples of “pau d’arco roxo” commercialized at markets in São Luís/ MA; also proven not allowed fungus by legislation in validity and specialized literature, exposing customers to risks of using vegetal drugs which are unfit for human consumption, which evidences therefore the need of a program of inspection, vigilance and quality control of vegetal drugs available for sale with medicinal aim at market places.

Las enfermedades transmitidas por los alimentos y su deterioro microbiano son el resultado de la incapacidad de regular o controlar los microorganismos en una o más etapas de la cadena alimentaria, desde la producción de la materia prima hasta el consumo del producto final. Este estudio se realizó para detectar algunas bebidas a base de cacao que se venden en Nigeria, con el fin de determinar el estado micológico y aflatoxínico de dichos alimentos. Setenta y nueve (79) muestras de diferentes marcas de bebidas de cacao recogidas de diferentes mercados en la ciudad de Benín (Nigeria), se evaluaron mediante la estimación de la carga de hongos; utilizando el método de recuento de placa estándar y el nivel de aflatoxina B1 (AFB1) por extracción de columna de gel de sílice de inmunoafinidad y cromatografía de capa fina con detección espectrofotométrica. Las colonias de moho aisladas de las muestras se identificaron mediante métodos micológicos estándar como Aspergillus flavus, Aspergillus niger y Aspergillus fumigatus. La muestra de bebidas Zamis registró el mayor recuento de hongos de 5500 ufc /g, nivel de AFB1 de 40,6 ± 3,2 μg/kg y contenido de humedad de 4,00%; mientras que la muestra de bebidas Peak registró el menor recuento de hongos de 500 ufc /g, el nivel de AFB1 de 5,3 ± 2,5 μg/kg y el contenido de humedad del 1.00%. AFB1 no se detectó en muestras de bebidas de Ovaltine y Benco. Los géneros más frecuentes de moho en todas las muestras fue A. flavus, con una incidencia de 63,3%. Las bebidas con bolsita de cacao que se venden en la metrópolis de Benin conllevan un riesgo potencial para la salud. Por lo tanto, una mejor manipulación a través del procesamiento, la conservación y el almacenamiento de los alimentos puede minimizar las aflatoxinas en los alimentos y garantizar una calidad sostenible del suministro de alimentos. Estos hallazgos sugieren la necesidad de una atención urgente a las posibles implicaciones para la salud pública.

O objetivo da pesquisa foi avaliar a eficiência dos extratos de alho e erva-cidreira sobre patógenos e na qualidade fisiológica de sementes de Chorisia glaziovii. Os tratamentos constituíram-se de extratos de alho e erva-cidreira à 0, 25, 50, 75 e 100%, e fungicida Captan®. Para sanidade das sementes adotou-se o método blotter test e a qualidade fisiológica foi determinada pela germinação e vigor. O delineamento foi inteiramente casualizados em esquema fatorial (2x5) +1 (extratos vegetais x concentrações + fungicida), com quatro repetições. Observou-se a ocorrência de Aspergillus flavus, Aspergillus niger, Aspergillus sp., Botrytis sp., Cladosporium sp., Curvularia lunata, Nigrospora sp., Pestalotia sp., Periconia sp. e Rhizopus stolonifer, nas sementes. O extrato de erva-cidreira à 100% foi eficiente na inibição dos patógenos. O aumento na concentração do extrato de alho foi prejudicial à primeira contagem de germinação, e o extrato de erva-cidreira proporcionou aumento de sementes germinadas.
