“…Health effects of wood-deteriorating fungi are less well known, but at least Serpi~la species (formerly called Merulius) is allergenic. It is impossible to give any complete list of allergenic microorganisms because new species are continuously being detected and reported (35,44,45).…”

“…Basidiospore periodicity remains unexplained. Although there is no well-defined season for fungi, 8 as the number of spores and pollen counted are influenced by the sampling technique, locality, surroundings, height above ground level, meterologic factors, and irrigation, as well as spore discharge rhythm (active or passive), both seasonal distribution and circadian pattern for one type or more may vary.…”

Seasonal Periodicities of Fungal Allergens in the Atmosphere of Riyadh

et al. 1989

Aerobiological studies to evaluate allergenic fungal spores in the atmosphere of Riyadh were conducted using Burkard volumetric 7-day recording spore trap and culture plate techniques from November 1986 through October 1987. Thirty-two generic and morphologic categories were recorded. The majority of these fungal spores belonged to dry-air spora of conidial fungi, originating from garbage, rubbish bins, stored fruits and vegetables, and the like. Cladosporium spp. constituted 24.8% (mean value) of total air spora over the 12-month period, ranging monthly from 8.5% to 40% ; smuts (Ustilago and other species) 13.4% (range, 1.6% to 25.6%); Alternaria spp. 5.6% (range, 1.9% to 9.6%); Ulocladium spp. 3.4% (range, 1.0% to 6.8%); Chaetomium 1.8% (range, 0.7% to 4.2%); Drechslera and Helminthosporium 1.8% (range, 0 to 5.4%). Basidiospores constituted 3.1% (range, 1.5% to 5.7%). Peak hourly concentrations for all categories were recorded, Cladosporium having the highest concentration. Seasonal periodicities showed an increase in concentration in the warmer months and a decline in the winter. The role of some fungal spores and pollen grains present in the air is well known in the etiology of respiratory allergic diseases such as asthma and allergic rhinitis. Before symptoms and exposure to such allergens can be related, however, information on the qualitative nature and distribution patterns is required.In a previous communication 1 we described the airborne fungal allergens identified in the atmosphere of Riyadh, using both viable and visual methods of trapping. This article describes the nature and distribution of airborne fungal spores based on 12 months of aerobiological studies in Riyadh from November 1986 through October 1987.

“…It has been reported that inhaling indoor allergens such as fungi or mites causes allergic rhinitis and asthma Nambu et al, 2009Salvaggio et al, 1981Verhoeff et al, 1995 . Thus, there is a consumer demand for equipment, such as air cleaners and vacuum cleaners, to effectively remove these indoor allergens.…”

To evaluate the removal of airborne microbes by air cleaners, a technique for generating airborne fungal spores in the dry state in a test chamber dry dispersion become necessary. The Society of Indoor Environment Japan SIEJ published SIEJ Standard Method No. 20110001 SIEJ standard , in which an aerial ultrasonic oscillator was used as the device for dry dispersion. However, a more versatile apparatus is also necessary from a practical point of view. Therefore, we developed a new device using glass beads for the dispersion. Glass beads and a fungal sheet containing spores of Wallemia sebi were set in a midget impinger, which was connected to a compressor and a compact test chamber 1 m 3 . Air was blown into the impinger from the compressor. The spores on the fungal sheet were released by impingement of the glass beads when the beads were induced to float by the air blown into the impinger, and the spores were introduced to the chamber by the airflow. This newly developed technique can be used in a compact chamber system and could be applicable as an improved method for generating airborne fungal spores in the dry state in the SIEJ standard.
