Total IgE concentration and percentage eosinophiles were measured in patients whose skin prick tests were positive to at least one of allergens under study, and in control person.
Results:
These results were obtained from current study: a total of 24.09 × 102 CFU belonging to twenty genera with a group of yeasts and twenty four species, and the percentage of most predominant isolated fungi from the environment at different locations of Sulaimani city were Penicillium spp. 28.1%, Aspergillus spp. 20.25%, yeast 13.33%, Cladosporium spp.12.1%, and Alternaria spp. 6.72%. The highest number of fungi was isolated during spring 14.92 × 102 CFU compared to 9.17 × 102 CFU in autumn, A.niger and A.flavus were the predominant species of Aspergillus isolated, while the most common Penicillium species were P. chrysogenum and P. spinulosum.
Conclusion:
The highest number of fungi were isolated from dietary factories 6.37 × 102 CFU followed by
houses 4.71 × 102, factories 4.21 × 102 CFU, dormitories 3.96 × 102, schools 3.32 × 102, and hospitals 1.52 × 102.
