Qualitative Analysis of Indoor and Outdoor Airborne Fungi in Cowshed

Abstract

Air pollution is one of the most serious problems to human health. Fungi are the causal agents for different diseases in animals, plants, and human beings. Otomycosis, chronic bronchitis, emphysema, asthma, allergy, and systemic mycosis are among the fungal diseases caused. The present study was conducted to analyze the monthly incidence of airborne fungi, seasonal variation, and influence of meteorological parameters in indoor and outdoor fungi of cowshed at Hesaraghatta village, Bangalore. An aeromycological survey of indoor and outdoor area of cowshed at Hesaraghatta village in Bangalore city was carried out using the Andersen two-stage sampler onto a petri dish containing malt extract agar from January 2011 to December 2011. Altogether, 29 species belonging to 13 genera from indoor and 26 species belonging to 12 genera were recorded from outdoor environment of the cowshed; the dominant fungal species identified were Cladosporium sp., Aspergillus sp., and Alternaria alternata. Seasonal occurrence of fungal spores in both indoor and outdoor of the cowshed revealed that maximum spores were recorded in summer season followed by winter and rainy season.
