Environmental conditions and airborne myco£lora were measured concurrently in 10 turkey confinement houses during warm and cold weather. The following variables in the environment were measured: numbers of feedand litter-associated yeast and mold fungi, temperature, relative humidity, airspeed, carbon dioxide and ammonia concentration, airborne bacteria, and airborne particulate mass, particle ...

Fungal DNA was selectively amplified, and the ITS region sequenced, from fecal samples taken from 45 healthy human volunteers at one (21 volunteers) or two (24 volunteers) time points. Seventy-two operational taxonomic units, representing two phyla and ten classes of fungi, were recovered. Candida yeasts, notably Candida tropicalis (present in 51 samples), and yeasts in the Dipodascaceae (39 sa...

The characterization and the main properties of biogenic airborne particles (or bioaerosols) comprising both living dead microorganisms (such as bacteria, fungi, viruses, pollen, microbial fragments) are currently increasing interest in scientific community [...]

To assess the diversity and composition of airborne fungi associated with particulate matters (PMs) in Beijing, China, a total of 81 PM samples were collected, which were derived from PM2.5, PM10 fractions, and total suspended particles during haze and non-haze days. The airborne fungal community in these samples was analyzed using the Illumina Miseq platform with fungi-specific primers targeti...

A study was undertaken to determine typical concentrations of airborne bacteria and fungi (microflora) in Teaching Hospital environment in Benin City in the tropical rainforest environment of Nigeria. Aerial sampling was conducted at various hospital wards each day. The air samples were collected thrice daily. Concentrations of airborne microflora exceeded available local guidelines for indoor ...

Confined animal production systems produce increased bioaerosol concentrations, which are a potential respiratory health risk to individuals on site and downwind. In this longitudinal study, airborne endotoxin and microorganisms were collected during the spring, summer, and fall at a large, open-freestall dairy in southern Idaho. Compared with the background ambient atmosphere, both endotoxin a...

results the main isolated fungal spores from the atmosphere of tabriz district were penicillium sp. (36.6%), cladosporidium sp. (26.8%) and aspergillus sp. (23.6%). conclusions the presence of fungal spores in the atmosphere as a part of air pollution can cause significant problems for human health, particularly in the respiratory tracts. background air contamination with fungal spores and the ...
