Abstract

Ganoderma fungal spores are a major component of the Auckland air-spora. Previous studies of ganoderma involvement in allergic asthma and rhinitis were extended by locating the sporophores (fruiting bodies) in the Auckland area and systematically collecting the ejected spores. Maximum production by one sporophore was 5 gram dry weight of spores in one week, equivalent to 11 billion spores. We have estimated that between 400 and 1200 sporophores would account for previously reported levels of ganoderma spores collected from the air by Burkhard spore traps. Both whole spores and extracts of spores were strongly immunogenic in rabbits. Of the 115 asthma patients who were skin prick tested with a variety of fungal extracts, 32 (28%) were positive to one or more fungi. Of these, 18 (16%) reacted positively to ganoderma extracts. A theory proposing how ganoderma might contribute to allergic hyperreactivity in susceptible patients is developed.
