Indoor damp surfaces harbor molds with clinical significance.

BACKGROUND AND PURPOSE

Fungal contamination in damp places in buildings has become an increasing problem worldwide. Dampness facilitates the growth of fungi, which can cause adverse effects not only on the buildings but also on their occupants. The aim of this study was to identify indoor mold species in the buildings of Kerman province, Iran.

MATERIALS AND METHODS

In this study, 110 samples were obtained from surfaces of damp indoor areas in buildings randomly selected in Kerman province. The identification of fungal species was based on the macroscopic and microscopic characteristics of the isolates, such as colony morphology, hyphae, conidia, and conidiophores, as well as molecular sequence data.

RESULTS

Based on the results, a total of 218 fungal isolates were obtained. Apart from frequently isolated fungi, such as , , and , 13 species, including , , , , , , , , , , , and were identified, and the selected species were described. Among these 13 species, was the most common species (43%) in indoor surfaces, followed by (10.8%) and (7.4%). To the best of our knowledge, was reported in the present study for the first time in Iran. In addition, and were isolated for the first time from indoor surfaces in Iran.

CONCLUSION

According to the results, the level of overall fungal richness across indoor surfaces was high. Some of the isolated taxa were clinically significant. It was concluded that the damp residential surfaces were potentially passive collectors of clinically significant molds.
