Filamentous fungi isolated from sand and water of "Bairro Novo" and "Casa Caiada" beaches, Olinda, Pernambuco, Brazil.

Fungi comprehend a heterogeneous group of heterotrophic microorganisms that act as saprobes or parasites or, less frequently, as symbionts living in association with other organisms. They are cosmopolitan and important components of ecosystems. Considering the small number of Brazilian papers on the filamentous mycota in marine environments, and the need to improve knowledge of the diversity of these microfungi in "Casa Caiada" and "Bairro Novo" beaches, Olinda, PE, the aim of this work was to isolate and identify the fungi from sand and water samples of these ecosystems. Thirty two samplings of sand (surface and 20 cm deep) and water (surface and 1 m deep) were carried out during the dry and rainy seasons, in low and high tide. From each sand sample, a suspension was made with 50 g of sand diluted in 90 mL of sterilized distilled water. From each sand suspension and water sample, 0.5 mL was spread, in triplicate, onto Petri dishes containing Sabouraud Agar added of chloramphenicol. The plates were incubated at 28 degrees C (+/-2 degrees C). Fifty seven species were isolated, identified, and classified in 20 genera. Aspergillus and Penicillium were the most frequent genera in both sand and water, with a total of 11 and 19 species, respectively.

Os fungos compreendem um grupo heterogêneo de microorganismos heterotróficos, atuando como sapróbios ou parasitas, ou menos freqüentemente como simbiontes, vivendo em associação com outros organismos. São cosmopolitas e componentes importantes dos ecossistemas. Considerando-se a escassez de trabalhos no Brasil que tratam da micota filamentosa em ambientes marinhos, e ainda a necessidade do conhecimento da diversidade desses microfungos nas praias de Casa Caiada e Bairro Novo, Olinda, PE, este trabalho teve como objetivo o isolamento e identificação de fungos, em amostras de solo e de água, desses ecossistemas. Foram realizadas 32 coletas do solo (em superfície e a 20 cm de profundidade) e da água (em superfície e a 1 m de profundidade), nos períodos de estiagem e chuvoso, na baixa-mar e preamar. De cada amostra de solo, foi feita uma suspensão de 50 g de solo em 90 mL de água destilada esterilizada, e de cada amostra de solo e água foi retirado 0,5 mL para o semeio em triplicata em placas de Petri contendo ágar Sabouraud acrescido de cloranfenicol e incubadas sob temperatura ambiente (28 ± 2 °C). Foram isoladas e identificadas 57 espécies correspondentes a 20 gêneros. Aspergillus e Penicillium dominaram tanto no solo quanto na água, com um total de 11 e 19 espécies, respectivamente.

Fungos isolados do ar e do piso de ambientes fechados do Hospital Escola da Universidade Federal de Pernambuco, Recife, Brasil-I / Fungi isolated from air and floor in closed enviroment in the Hospital Escola da Universidade Federal de Pernambuco, Recife, Brasil-I

Del aire y del piso de ambientes confinados del "Hospital das Clínicas da Universidade Federal de Pernambuco, Recife, Brasil", fueron aisladas 3.330 colonias de hongos correspondientes a 123 entidades taxonómicas pertenecientes en su mayoría a los Asco-Deuteromycotina (95,3%), estando los demás grupos escasamente representados Zigomycotina (5,6%); Basidiomycotina (0,8%) y Micelia sterilla (0,2%). No hubo diferencias significativas entre la cantidad de colonias aisladas durante los períodos de pluviosidad y verano. Observándose el mayor número de colonias en el piso más que en aquellas aisladas del aire atmosférico. Los géneros encontrados con mayor frecuencia fueron Aspergillus, Penicillium y Fusarium. Entre los Hyphomycetes aislados, 14 especies son referidas como agentes etiológicos de micosis
