13. MICOLOGIA FORENSE: A DINÃMICA DA MICROBIOTA FÃNGICA NA INVESTIGAÃÃO DO PERÃODO POST MORTEM
Com o evoluir das observaÃÃes mÃdico-legais, determinadas espÃcies de insetos e microrganismos foram descritos como indicadores de perÃodos da degradaÃÃo do corpo. Entretanto, a literatura cientÃfica ainda à escassa no campo da Micologia Forense. Assim, investigaram-se as caracterÃsticas microbiolÃgicas dos fungos partÃcipes na mudanÃa de flora

14. Fungos endofíticos em Annona spp.: isolamento, caracterização enzimática e promoção do crescimento em mudas de pinha (Annona squamosa L.)
A partir de folhas, caules e raízes de plantas de pinha e graviola coletadas em Pernambuco foram obtidos 110 e 90 isolados fúngicos endofíticos, respectivamente. Vinte e nove isolados foram selecionados e avaliados quanto à produção de enzimas extracelulares, através do método qualitativo em placas com meios sólidos específicos, e à capacidade de

15. Evaluation of the presence of fungi in samples of raw milk and study of the susceptibility of these microorganisms to the temperature/time rates employed in pasteurization and boiling processes / Avaliação da presença de fungos em amostras de leite cru e estudo da susceptibilidade destes microrganismos às relações temperatura/tempo empregadas nos processos de pasteurização e fervura
The present study was outlined considering the importance of filamentous fungi and yeasts, associated to various pathologies in man and animals. It must be considered that milk and dairy products when contaminated with these microorganisms can represent a potential means of zoonosis transmission related to them. Samples of raw milk types A, B and C, collecte

16. Flora fúngica do trato digestivo de Rhodnius prolixus, Rhodnius neglectus, Diptelanogaster maximus e Panstrongylus megistus vetores de Trypanosoma cruzi, Chagas 1909
Um estudo da micobiota do trato digestivo de quatro importantes espécies de triatomíneos, Rhodnius prolixus, R. neglectus, Diptelanogaster maximus e Panstrongylus megistus, foi realizado. Foram examinados os tratos digestivos de 90 adultos e 425 ninfas destas espécies de triatomíneos e 365 cepas fúngicas foram isoladas. Os gêneros com o maior número d

17. Microflora fúngica de sementes de milho em ambientes de armazenamento
Durante o armazenamento, vários fungos podem permanecer associados às sementes de milho, causando deterioração ou se mantendo viáveis, infectando posteriormente a plântula. Objetivou-se neste trabalho verificar a sobrevivência de fungos associados às sementes de milho durante 12 meses de armazenamento, em câmara fria (14ºC; 40% UR) e em ambiente n�

18. Relationships among non-Acremonium sp. fungal endophytes in five grass species.
Many cool-season grasses (subfamily Pooideae) possess maternally transmitted fungal symbionts which cause no known pathology and often enhance the ecological fitness and biochemical capabilities of the grass hosts. The most commonly described endophytes are the Acremonium section Albo-lanosa spp. (Acremonium endophytes), which are conidial anamorphs (strictl

19. In Vitro Susceptibility Testing of Filamentous Fungi: Comparison of Etest and Reference Microdilution Methods for Determining Itraconazole MICs
The performance of the Etest for itraconazole susceptibility testing of 50 isolates of filamentous fungi was assessed in comparison with the National Committee for Clinical Laboratory Standards (NCCLS) proposed standard microdilution broth method. The NCCLS method employed RPMI 1640 broth medium, and MICs were read after incubation for 48 h at 35°C. Etest M

20. Genetic Diversity among Clinical Isolates of Acremonium strictum Determined during an Investigation of a Fatal Mycosis
Primarily saprophytic in nature, fungi of the genus Acremonium are a well-documented cause of mycetoma and other focal diseases. More recently, a number of Acremonium spp. have been implicated in invasive infections in the setting of severe immunosuppression. During the course of routine microbiological studies involving a case of fatal mycosis in a nonmyelo

21. Isolation and properties of fungi that lyse blue-green algae.
Of 70 pure microbial cultures isolated from aquatic habitats, soil, and air according to the ability to lyse live blue-green algae, 62 were fungi representing the genera Acremonium, Emericellopsis, and Verticillium. Algal-lysing fungi were isolated from all habitat types sampled. The remaining isolates comprised four bacteria and four streptomycetes. All iso

22. A Novel Fungal Protease Expressed in Endophytic Infection of Poa Species.
The fungus Acremonium typhinum produces a novel endoprotease during symbiotic endophytic infection of the grass, Poa ampla. This protease is unusual because it is highly active in the presence of sodium dodecyl sulfate. The enzyme is a thiol-containing serine protease and is localized to a crude membrane fraction. Similar protease activity has been detected

23. Contaminations Occurring in Fungal PCR Assays
Successful in vitro amplification of fungal DNA in clinical specimens has been reported recently. In a collaboration among five European centers, the frequency and risk of contamination due to airborne spore inoculation or carryover contamination in fungal PCR were analyzed. The identities of all contaminants were specified by cycle sequencing and GenBank an

24. Identification of Fusarium Species Involved in Human Infections by 28S rRNA Gene Sequencing
Fusarium spp. have emerged as major opportunistic fungal agents. Since new antifungal agents exhibit variable activity against Fusarium isolates depending on the species, rapid identification at the species level is required. Conventional culture methods are difficult, fastidious, and sometimes inconclusive. In this work, we sequenced a 440-bp fragment encod
