ABSTRACT
Indoor visible mold growths are known to be associated with allergies and respiratory illnesses. However, a question remains of their compositions and diversities. Using swab sampling and high-throughput DNA sequencing, this study analyzed taxonomic compositions and diversities of fungi on indoor surfaces laden with visible mold growths in residential apartments in South Korea. The sequencing results showed low species diversities with Shannon indices ranging from 0.14 to 2.29 (mean = 1.11). Several allergy-related genera were detected on the same surface, where the most abundant Cladosporium with a mean relative abundance of 41% co-occurred with less abundant Aspergillus (0.094%), Rhodotorula (6.3%), Cryptococcus (3.7%), Alternaria (4.1%), and Crivellia (17%). ß diversity analyses showed significant differences in the fungal communities between enclosed balconies and other indoor areas (P < 0.05, ANOSIM), emphasizing a need to sample at multiple indoor locations when assessments are made for indoor visible mold growths. High-throughput sequencing is powerful in characterizing compositions and diversities of fungal communities. Future studies should examine the relationships between taxonomic compositions and diversities of indoor visible molds and health outcomes of allergies and respiratory illnesses in residential buildings.
