Aspergilus sp: The genus Aspergillus includes over 185 species. Around 20 species have so far been reported as causative agents of opportunistic infections in man. Among these, Aspergillus fumigatus is the most commonly isolated species, followed by Aspergillus flavus and Aspergillus niger. Aspergillus clavatus, Aspergillus glaucus group, Aspergillus nidulans, Aspergillus oryzae, Aspergillus terreus, Aspergillus ustus, and Aspergillus versicolor are among the other species less commonly isolated as opportunistic pathogens.
A. fumigatus: A rapidly growing fungus that produces a bluish-green colony within ten days, when incubated at 25C (77F). It is a thermotolerant fungus and is very common worldwide. It can be isolated from air, plants, foodstuffs, soil, sand beaches, caves and mines, activated sludge, mangrove swamps, fresh water, compost, animal dung, silage, fodder, and cotton fabrics in the tropics. It is one of the most common causes of systemic fungal disease in humans and animals causing acute or chronic respiratory tract infections. It is a well documented allergen.
