Background and Purpose: Airborne fungi are one of the most important agents responsible for triggering allergic reactions such as rhinitis and severe asthma. This study was conducted to analyze and monitor the prevalence and distribution patterns of atmospheric fungal aerosols in the air of Qazvin during winter of 2012. Materials and Methods: In the current descriptive study, the incidence ...

Abstract The conservation actions towards artworks holding a common patrimony for the community are of primary importance, but also those related to their "container" as museums, libraries or archives consider. Fungal spores and bacteria carried by air flows artwork surface can colonize it causing biodeterioration through physical and/or chemical alterations materials with irreversible loss val...

Many ailments can be linked to exposure to indoor airborne fungus. However, obtaining a precise measurement of airborne fungal levels is complicated partly due to indoor air fluctuations and non-standardized techniques. Electrostatic dust collector (EDC) sampling devices have been used to measure a wide range of airborne analytes, including endotoxins, allergens, β-glucans, and microbial DNA in...

Cryptococcus neoformans was first described as a human fungal pathogen more than a century ago. One aspect of the C. neoformans infectious life cycle that has been the subject of earnest debate is whether the spores are pathogenic. Despite much speculation, no direct evidence has been presented to resolve this outstanding question. We present evidence that C. neoformans spores are pathogenic in...

Aspergillus fumigatus is a ubiquitously present respiratory pathogen. The outcome of a pulmonary disease may vary significantly with fungal viability and host immune status. Our objective in this study was (1) to assess the ability of inhaled irradiation-killed or live A. fumigatus spores to induce allergic pulmonary disease and (2) to assess the extent to which inhaled dead or live A. fumigatu...

Fungal spores are an ever-present component of the atmosphere, and have long been known to trigger asthma and hay fever symptoms in sensitive individuals. The atmosphere around Tulsa has been monitored for airborne spores and pollen with Burkard spore traps at several sampling stations. This study involved the examination of the hourly spore concentrations on days that had average daily concent...

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...

Indoor bioaerosols, such as mold spores, have been associated with respiratory symptoms in patients with asthma; however, dose-response relationships and guidelines on acceptable levels are lacking. Furthermore, a causal link between mold exposure and respiratory infections or asthma remains to be established. The aim of this study was to determine indoor concentrations of Aspergillus fumigatus...

A technique for inoculation with precise numbers of fungal spores on leaves and stems of plants was developed. The technique consisted of placing 1-μl drops with a fixed number of spores on the surface of leaves and stems, and covering each inoculum drop with a 10-μl drop of low-temperature gelling SeaPlaque agarose to fix the inoculum on the target site. With this technique single zoospores of...
