Variations in pollen and fungal spore air spora: an analysis of 30 years of monitoring for the clinical assessment of patients in the Western Cape
Background and aims: Pollen and fungal spore concentrations in the atmosphere of Cape Town have been monitored since 1984 in two areas of Cape Town. Volumetric spore traps were used to monitor the air spora that trigger allergic disease in susceptible individuals. A pollen count was produced for …

Quantification of Airborne Fungal Spores Comparing Molecular Tracers via Ion Chromatography and UV-LIF Methods
<p>Fungal spores represent an understudied subcategory of bioaerosols that can impact human health as pathogenic and allergenic particles. Fungal spores also have been shown to act as effective ice nuclei and giant cloud condensation nuclei in some cases. This has implications on the hydrological …

The pollen and spores of metropolitan Cape Town and their relationship with meteorological conditions
… in general, is the dominant atmospheric fungal spore. Fungal spores are, quantitatively, the dominant partner in the atmosphere. Meteorological factors such as wind speed and wind direction, precipitation, temperature, relative humidity, atmospheric pressure and atmospheric stability have …

Beneficial Fungal Interactions Resulting in Accelerated Germination of Astragalus utahensis, a Hard-Seeded Legume
… seed. Inoculated seed trials (1.0 x 106 spores/mL) exhibited a highly significant difference in percent germination between the uninoculated control at 5.0 % germination and seeds inoculated with Alternaria and Aspergillus germinating at 95 % and 55 %, respectively. Germination trials …

The Effects of Nitrogenous Compounds on Decay of Wood by Soft-Rot Fungi
… study soft-rot decay of wood. This enabled pure fungal cultures to be used to inoculate the wood and may be considered to simulate conditions which result in soft-rot decay of wood not in ground contact. Fungal spore suspensions were used to inoculate wood blocks which had received additional …

Anting Behavior in Birds: Ant Selection and Effect of ant Chemistry on Feather Ectoparasites
… and <em>Trichoderma viride </em>or fungal spore germination. Formic acid inhibited growth of all microbial species and spore germination of <em>C. globosum</em>. Dust bathing site location in Wild Turkeys was not related to the presence of preferred ant species, indicating no …

Feedbacks between plants, flow, and particle fate
… by sediment, and may be killed by disease spores. While the influence of vegetation on flow profiles has been investigated, the transport of particles within vegetated canopies remains poorly understood. In this thesis I present the results from laboratory experiments and numerical modeling …

Biofiltration of volatile organic compounds using fungal-based bioreactors
… surfactant washing affected pollutant removal in fungal biofilters. In experiments to evaluate the influence of nitrogen supply on bioreactor performance, it was determined that a nitrogen mass loading of approximately 2% of the carbon mass loading was needed to achieve near-complete removal of …

The Decay of Aerosol Concentration as a Function of Time Comparing the Effects of AHPCO and Bi-Polar and an Analysis of Aeroallergens, Fungal Spores and Pollen in the Texas Panhandle Area
… medication, insect venom and also mold spores and pollen; causing an allergy, a sensitivity to these substances that are normally harmless to people (Ghosh et al., 2017). In this study I analyzed the two most common types of aeroallergens, fungal spore and pollen. The analysis was done …

Acute Pulmonary Response in Landscape Workers: Job Redesign
… agents of respiratory spasms are endotoxin, fungal spores, and fungal mycotoxin. This study focused on the respiratory hazards in the landscaping industry. During the month of March, landscapers worked heavily with wood mulch, which contains many organic materials that potentially harbor the …

Biological control of wood decay in ground contact timbers
… means of protecting ground contact timbers from fungal decay. <i>Trichoderma </i>spp. are soil-inhabiting fungi with broad-spectrum antagonistic properties, and have been extensively investigated as potential biocontrol agents in agriculture and forestry. <br/><br/>A small-scale wood-based …

A prospective cohort study on ambient air pollution, airborne pollen (and fungal spores) and respiratory morbidities including childhood asthma in adolescents from the Western Cape Province
… exposures to ambient air pollutants as well as fungal spores on asthma-associated outcomes. This study systematically investigated these factors among schoolchildren residing in informal settlements in the Western Cape province of South Africa. Methods: A cohort study of grade-4 schoolchildren …
