Abstract
In the present study air samples from (outdoor and indoor) as well as soil were collected during four seasons and subjected for mycological study. Fungal isolates in the collected air samples were cultivated by sedimentation method while fungal isolates from soil were cultivated by dilution method and hair bait techniques. The obtained results can be summarized as following:
1-Outdoor samples revealed the isolation of 14 genera which identified to 19 species. The predominant fungi in fall were A.niger A.flavus and C. cladosporiodes. In winter the predominant was A.niger Rhodotorula mucilaginosa was the commonest in spring and A.flavus were the predominant in summer.
2-Indoor samples revealed the isolation of 19 genera which identified to 20 species. The predominant fungi in fall were A.niger while A.niger, C. cladosporiodes and M.recemosis in winter were the predominant. A.niger were the commonest in spring. And A.niger, C. cladosporiodes were the predominant in summer.
3-Soil samples revealed the isolation of 19 genera which identified into 25 species. The predominant fungi in fall, winter and spring were A.niger while A.flavus was the predominant fungi isolated in summer. On the other hand Cryptococcus neoformance was isolated from soil contaminated by pigeon droppings. Keratinophilic fungi namely M. gypseum and chrysosporium tropicum were isolated from soil collected from animal houses.
4-Some of the isolated fungi were tested for the antifungal effect of garlic, onion and pepper. Garlic showed antifungal effect against A.niger, A.flavus, A.fumigatus, F.oxysporum, P.chrysogynum and C.albicans. Onion showed antifungal effect against A.flavus, A.fumigatus, F.oxysporum, P.chrysogynum and C.albicans, while pepper showed antifungal effect on A.niger and P.chrysogynum.
