Abstract
This is the first study to isolate and identify the aeromycoflora of Jizan province. The study was carried out to estimate quantitatively and qualitatively the mycoflora present in the air of different sampling sites of the province. Open petri plate method with Potato Dextrose agar media was used with an exposure time of 2 mins. at each of the seven sampling sites. Total number of eight genera were isolated from the seven indoor and outdoor sampling sites of the province represented by Aspergillus niger, Aspergillus sp., Chaetomium, Cladosporium, Nigrospora, Penicillium, Rhodotorula, Scedosporium and Ulocladium. Seventy two fungal isolates were obtained from the eight represented genera. Aspergillus was the predominant genera. The Colony forming unit (CFU)(3) was calculated for all of the sampling sites under study to know the level of contamination. The high wind speed and the busy hours of business were the major factors responsible for large number of fungal counts during this study from the province.
