Background: Fungi are known as one of the most important biological agent of air pollution, which grown on a vast majority of organic materials and act as allergens, toxic and opportunistic in immunosuppressed, diabetic and malignancies. Textile factories are known as a high risk industry that contaminated with fungal spores and metabolites. Since Yazd is one of the most important textiles industrial centers, this study was conducted to determine the fungal airborne and their types in Yazd textile factories. Material and methods: Totally 235 air samples from textile indoor of 30 randomly selected Yazd textile factories and 22 samples from outdoor air samples as control were collected. The filters were cultured onto the specific media as the NIOSH standard technique for isolation of fungal agents. The frequency and types of contaminated and isolated fungi were determined based on Colony Forming Units in the cubic meter (CFU/m3). Data were analyzed based on the survey objectives using statistical tests. The average fungal isolation in out door was used as a standard control for comparing the fungal indoor airborne fungi. Results: Totally 927 colonies from 16 different genus of fungi were isolated and determined from air samples of textile factories. The average indoor fungal concentration was 121.5 CFU/m3 more than the outdoor (61.4 CFU/m3) fungal concentration (P= 0.001). Penicillium, Aspergillus and Cladosporium were the most prevalent isolated fungal spores. The fungal contamination rates were more prevalence in the small factories than bigger factories and also in few factories, which usually used the natural based fiber was more contaminated than those used synthetic fibers (P=0.0001). The fungal contamination was much higher in the factories indoor air samples taken from weaving, spinning, knitting and finishing areas than those isolated from the outdoor control air samples (P
