Different spore types are abundant in the atmosphere depending on the weather conditions. Ascospores generally follow precipitation, while spore types such as Alternaria and Cladosporium are abundant in dry conditions. This project attempted to correlate fungal spore concentrations with meteorological data from Tulsa, Oklahoma during May 1998 and May 1999. Air samples were collected and analyze...

cellobiose dehydrogenase (cdh ec.1.1.5.1) is an extracellular enzyme that mainly produced by wood-degrading fungi. it oxidizes cellobiose to cellobionolactone using a wide spectrum of electron acceptors. the key roles of cdh in growth, metabolism, and some other important cellular processes such as cellulose degradation in fungi have been noted. since the demands for finding new sources of cdh ...

background nosocomial fungal infections could arise from independent exposure to airborne spores of filamentous fungi existing in the hospital environment. objectives the present study aimed to determine the mycoflora of indoor and outdoor environments of five major hospitals in khorramabad, iran. materials and methods sampling of air was done from indoor and outdoor environments of wards, surr...

BACKGROUND Allergy to airborne fungi can cause rhinitis and severe asthma, hence the exposure to spores inside home is an important factor of sensitization. The aim of this study was to determine the distribution and prevalence of species of Alternaria, Aspergillus, Cladosporium and Penicillium inside and outside of homes of patients allergic to fungi and to evaluate seasonal variations. METH...

Cladosporium herbarum is an important allergenic fungal species that has been reported to cause allergic diseases in nearly all climatic zones. 5-30% of the allergic population displays IgE antibodies against molds. Sensitization to Cladosporium has often been associated with severe asthma and less frequently with chronic urticaria and atopic eczema. However, no dominant major allergen of this ...

The aeropalynological monitoring was carried out from 1 February 2005-31 January 2007. The total number of spores collected during the main spore season (MSS) in 2005 was 4,500 for Alternaria and 93,744 in the case of Cladosporium, whereas in 2006 values were increased (8,385 for Alternaria and 150,144 for Cladosporium), reaching the maximum concentrations on 18 July and 17 June 2006 with 344 a...

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...

Filamentous fungi produce a great variety of enzymes, and research on their biotechnological potential has recently intensified. The objective of this work was to identify, at the species level, using DNA barcoding, 46 fungal isolates obtained from maize grains with rot symptoms. We also analyzed the production of extracellular amylases, cellulases, proteases and lipases of 33 of those fungal i...

The dematiaceous fungi are a group of pigmented hyphal yeasts best known as agents of chronic skin and subcutaneous infections. Extracutaneous disease is exceptional. We report herewith a case of necrotizing granuloma caused by one member of the group, Cladophialophora bantiana. This organism is fully capable of invading the nervous system of apparently immunocompetent hosts and in many cases d...
