AIM The aim of this paper is to provide information about the concentrations of airborne bioaerosols (airborne bacteria, fungi and endotoxins) in outdoor suburban environments in Ostrava, Moravian-Silesian region, Czech Republic. METHODS The methods were based on systematic bioaerosol monitoring during one calendar year, subsequent analysis of the samples and statistical processing. The regre...

In countries that are humid throughout the year, mold is a common problem that can occur even on a computer keyboard. Mold is smelly and may damage computer keyboards. It is caused by fungal spores in the air. It can also affect occupants’ health. This study aimed to evaluate the efficiency of potassium sorbate as a biocide to reduce the viability of indoor airborne fungus in a higher education...

Under sustained, elevated building moisture conditions, bacterial and fungal growth occurs. The goal of this study was to characterize microbial growth in floor dust at variable equilibrium relative humidity (ERH) levels. (...) Quantitative PCR and DNA sequencing of ribosomal DNA for bacteria and fungi were used to quantify growth and community shifts. Over a one week period, fungal growth occu...

Microbial aerosol whose species and concentrations are closely related to human health is ubiquitous. The effect of microbes on human and animal health and production performance is, in many cases, caused by the spreading of air. Samples in this experiment were from a live poultry market (LPM) in Tai'an, China, collected three times a day (8 am, 14 pm, and 20 pm) over three consecutive days eac...

Background & Aims: Fungi are among the most important biological agents in air pollution. Textile factories are known as high risk places for contamination with fungal spores and metabolites. Since Yazd is one of the most important textile industry centers, this study was conducted to determine the concentration and types of airborne fungi in Yazd textile factories. Methods: A total of 235 indo...

Most airborne microorganisms are natural components of our ecosystem. Soil, vegetation and animals, including humans, are sources for aerial release of these living or dead cells. In the past, assessment of airborne microorganisms was mainly restricted to occupational health concerns. Indeed, in several occupations, exposure to very high concentrations of non-infectious airborne bacteria and fu...

Introduction:The infections resulting from opportunist invasive fungi,such as Aspergillus,are an increasingly developing problem in haspitalized patients especially those suffering from immunosuppressive deficiencies.   Method:In this study,air sampling from selected wards of three hospitals affiliated to Kerman University of Medical Sciences was carried out 2 times/day over 7 months (May-Oct...

Fungal spores can account for large proportions of air particulate matter, and they may potentially influence the hydrological cycle and climate as nuclei for water droplets and ice crystals in clouds, fog, and precipitation. Moreover, some fungi are major pathogens and allergens. The diversity of airborne fungi is, however, not well-known. By DNA analysis we found pronounced differences in the...
