BACKGROUND Indoor dampness increases the risk of indoor fungal growth. A complex interaction between occupant behaviors and the built environment are thought to affect indoor fungal concentrations and species diversity, which are believed to increase the risk of having asthma, exacerbation of asthma symptoms, or both. To date, no systematic review has investigated this relationship. OBJECTIVE...

A rapid technique is described for propagation, harvest, and purification of gram quantities of conidia of five Aspergillus and six Penicillium species.

Background: Among important fungi associated with foods are Aspergillus spp., Penicillium spp., and Geotrichum spp. In this study, we evaluated antifungal effects of Essential Oils (EOs) of Zataria multiflora, Mentha pulegium, and Mentha piperita.   Methods: Antifungal properties of EOs of M. piperita, M. pulegium, and Z. multiflora against Aspergillus spp., Penicillium spp., and Geotrichum ca...

Tomatoes are soft skin fruits highly susceptible to fungi contamination, mainly through injured skin or damaged tissues (AYRES; KRAFT; PIERCE, 1964; PEARSON; HALL, 1975). Strains from several fungi species are known to produce toxins on tomatoes during field production or storage. In the U.S.A., the main fungi genera found in tomatoes were Alternaria, Aspergillus, Botrytis, Cladosporium, Collet...

In this study, the author examined the cross-reactivities of Stachybotrys chartarum, Aspergillus niger/fumigatus, and Penicillium notatum with affinity-purified rabbit sera. The molds were grown for expression of maximum numbers of antigens, after which they were extracted and mixed with commercially available extracts. The mixture was used for antibody preparation in rabbits, measurement of an...

Two aromatic butenolides, aspernolides A and B along with the known metabolites, butyrolactone I, terrein and physcion were isolated from the fermentation broth of a soft coral derived fungus Aspergillus terreus. The structures of these metabolites were assigned on the basis of detailed spectroscopic analysis. The absolute stereochemistry of aspernolides A (1) and B (2) was established by their...

OBJECTIVES The main objective was analysis and assessment of toxinogenic capabilities of fungi isolated from moldy surfaces in residential rooms in an urban agglomeration situated far from flooded areas in moderate climate zone. MATERIAL AND METHODS The assessment of environmental exposure to mycotoxins was carried out in samples collected from moldy surfaces in form of scrapings and airborne...

Cereal crop plants are colonized by many fungal species such as Aspergillus ochraceus and Penicillium verrucosum, which produce ochratoxins, and Fusarium graminearum, which produces trichothecene mycotoxins. A multiplex real-time PCR method using TaqMan probes was developed to simultaneously detect and quantify trichothecene producing Fusarium species and ochratoxin A producing Penicillium and ...

Soil is a complex biological system that plays a key role for plants and animals, especially in dry forests such as the Caatinga. Fungi from soils, such as Aspergillus and Penicillium, can be used as bioindica- tors for biodiversity conservation. The aim of this study was to isolate and identify species of Aspergillus and Penicillium in soil, from the municipalities of Tupanatinga and Ibimiri...

The minimum effective concentration (MEC) used to assess the in vitro antifungal activity of caspofungin against Aspergillus spp. is a qualitative endpoint requiring microscopic examination of hyphae. We therefore developed a tool for the quantitative assessment of caspofungin activity against Aspergillus spp. at clinically applicable concentrations. Susceptibility to caspofungin (0.008 to 8 mi...
