Allergic diseases such as allergic rhinitis, pharyngitis, laryngitis, asthma, airborne dermatitis, or allergic conjunctivitis, can be caused or aggravated by components of bioaerosol from natural environment or from indoor environment in enclosed spaces, workplaces and homes. The main components of bioaerosol are fungi and their metabolites, which are common in the environment.

background the importance of preserving and maintaining printed materials is crucial for the libraries. fungi play the main role in destroying wood and paper. objectives this research aimed to study and identify threatening fungal agents of library resources in isfahan university of medical sciences. materials and methods this is a descriptive analytical study. 126 samples were collected and ex...

From plate counts of the airborne microorganisms in the downwind dust plume of operating grass-seed combines, the mean source concentrations were calculated to be 6.4 x 10 and 4.7 x 10/m, respectively, potentially accounting for at least 41.9% of the bacteria and 35.1% of the fungi in the airshed in the Willamette Valley, Oregon.

BACKGROUND Airborne fungi are responsible for the majority of fungal infections in humans and animals. Outdoor air markedly influences the prevalence of fungal spore levels in indoor air and thus, it is the major source of fungal infections in indoor environments especially in hospitalized individuals. METHODS Using a settle plate method, air sampling (1092 air samples from 93 sampling sites ...

OBJECTIVES The indoor environment of modern office buildings represents a new ecosystem that has been created totally by humans. Bacteria and fungi may contaminate this indoor environment, including the ventilation systems themselves, which in turn may result in adverse health effects. The objectives of this study were to test whether installation and operation of germicidal ultraviolet (GUV) l...

This study assessed the composition of aeromycota at a grain mill and four dwellings (two apartments and two basements) as well as in outdoor air during one year in Zagreb, Croatia. The incidence of Aspergilli from sections Flavi, Nigri, and Versicolores was also assessed. Airborne fungi were collected using an air-sampler and DG-18 agar plates. The average concentrations of airborne fungi in t...

The level of airborne microbes in hospitals is unknown in the United Arab Emirates (UAE). An investigation of the quantity and quality of airborne microbes in Al-Ain hospital, UAE, was carried out to establish standards for future reference. Using a bacteria mechanical air sampler, microbiological samples were collected from different hospital units. The bacterial and fungal isolates were enume...

With a growing awareness of the potential hazards of chemical and biological agents in our homes, schools and workplaces, a greater emphasis has been placed on evaluating the role of mycotoxins and mycotoxin-producing fungi in our indoor environments. Now, more then ever, the potential health effects of airborne molds and other biological contaminants are being given serious consideration in IA...

In the indoor environment, people are exposed to several fungal species. Evident dampness is associated with increased respiratory symptoms. To examine the immune responses associated with fungal exposure, mice are often exposed to a single species grown on an agar medium. The aim of this study was to develop an inhalation exposure system to be able to examine responses in mice exposed to mixed...

The aim of this study was to assess the volume of airborne fungi in the indoor and outdoor environment of poultry and cattle houses in the Mazandaran Province in Iran. Indoor and outdoor air of twenty cattle houses and twenty-five poultry houses were sampled using a single-stage impactor, which draws air at 20 L min-1 and impacts sampled material onto Petri plates containing malt extract agar. ...
