Abstract

A comparative survey of airborne fungal spores in fiveindoor and five outdoor environments in Burdwan, WestBengal, India, was carried out for a period of twoyears using rotorod samplers and sedimentation plates(culture plate). A total of 29 spore types wereidentified, of which three were Phycomycetous (Mucor, Rhizopus, Syncephalastrum), one Ascomycetous(Chaetomium), one Basidiomycetous (Ganoderma) and the remainder were Fungi Imperfecti. The results revealed lowest count during summer andmaximum during the rainy season. Aspergilluswas quite abundant in all the environments surveyed. The predominance of Aspergillus, Curvularia,Alternaria, Cladosporium, Drechslera, Fusarium in allthe surveyed environments has been attributed to theirability to grow in various substrata. The occurrenceof Cladosporium in the winter months suggestthat it is sensitive to high temperature. Allspore types were common in both environmentsexcept Bispora, Cercospora, Papularia, Spegazzinia, Trichothecium in the outdoor sites. Acorrelation has been made between the volumetriccomposition of airspora and the incidence of seasonalmold allergy.
