Abstract
A quantitative and qualitative survey was carried-out for airborne fungus spores coming into contact with horizontally and vertically gravitation sampling oriented surfaces in the atmosphere of Giza city. Czapek Dox agar, Malt extract agar, Potato dextrose agar and Sabouraud dextrose agar Petri dishes were exposed monthly to the five oriented surfaces of a polystyrene cube, throughout a one-year period. Significant differences (P< 0.01) were observed between the total counts of caught airborne fungi contacting with the horizontal compared to other vertically oriented surfaces. Conversely, there were no significant differences observed between the total catch of airborne fungi using the various sampling media. The results revealed that vertical sampling provides valuable information that may be lost from horizontal sampling alone. A total of 5053 colonies belonging to 40 fungal organisms were identified. Alternaria (24.26%), Aspergillus (19.2%), Cladosporium (14.5%) and Penicillium (11.43%) were the most predominant fungal genera. Collected fungi were grouped into high, medium, low and rare components depending upon their frequency in the studied atmosphere. Aspergillus niger, Aspergillus parasiticus, Alternaria, Cladosporium and Penicillium were regularly found at the all oriented surfaces. However, Arthrobotrys, Biospora, Chaetomium, Pleospora, Trichothecium and Verticillium were rarely found in the air. Positive and/ or negative correlations were observed between the total fungal counts and the predominant fungal types with meteorological parameters during sampling days. |
