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...

An investigation method to evaluate microbiological air quality has been developed; it involved a compiling building inspections checklist and occupants questionnaires, choosing sites, sampling frequency and analysis procedures. This method has been applied in a representative building with HVAC system and open-space offices. Air samples and microclimate parameters were collected at the same ti...

With the rapid development of greenhouses, indoor air quality, particularly airborne microorganisms, is closely related to health farmers and needs more attention. In this study, concentrations fungi at seedling, fruiting harvesting stages in typical tomatoes greenhouses were tested. Temperature, relative humidity microbial analysed. It was found that dominant fungal genera are Aspergillus Clad...

Background: Bio aerosols include airborne micro-organisms such as bacteria, fungi, viruses, etc and their products. Exposure to a bio aerosol is linked with a broad spectrum of health problems, including infectious diseases, acute toxic effects, allergies, and cancer. The aim of this study was to evaluate the quality and quantity of bio aerosols found in the air of different wards in Valiasr Ho...

The Pastorex Aspergillus antigen test for detection of Aspergillus galactomannan antigen in the sera of patients with invasive aspergillosis is used in many clinical laboratories. A serum sample contaminated with Penicillium chrysogenum gave a strongly positive reaction (1:128) which was heat stable, was not eliminated by pronase treatment, and was not detected by a normal rabbit globulin contr...

Limitations and Considerations in Air Sampling, Sample Analysis and Result Interpretation for Airborne Mould Spores by Jackson Kung’u Airborne mould material particularly spores are recognized allergens at normal concentrations to an estimated 20% of the population (Kendrick, 2000). It is not always possible to establish a correlation between mould spore counts in the environment and the presen...

The predominant hypothesis regarding the composition of microbial assemblages in indoor environments is that fungal assemblages are structured by outdoor air with a moderate contribution by surface growth, whereas indoor bacterial assemblages represent a mixture of bacteria entered from outdoor air, shed by building inhabitants, and grown on surfaces. To test the fungal aspect of this hypothesi...

Problem statement: There is growing concern about landfill adverse health effects from exposure to landfill emissions. Approach: Airborne dust samples from houses near Jeleeb AlShuyoukh landfill and control residences were analyzed for molds and bacteria and Volatile Organic Compounds (VOCs) each month for one year. Results: The number of mold species was greater in the residences close to Jele...
