Aspergillus collected in specific indoor settings: their molecular identification and susceptibility pattern

Abstract: Exposure to Aspergillus conidia is an increased risk factor for the development of respiratory symptoms. The emergence of azole resistance in Aspergillus fumigatus is a major concern for the scientific community. The aim of this study was to perform the molecular identification of Aspergillus species collected from different occupational and nonoccupational indoor settings and to study the azole susceptibility profile of the collected Fumigati isolates. The selected Aspergillus isolates were identified as belo… Show more

“…In all studies, the fungal contamination was characterized focusing on Aspergillus genera due to clinical and toxicological relevance from the Aspergillus sections [ 12 , 21 ], EDC provided information concerning fungal azole resistance in all the performed studies presented in Table 1 , unveiling more data regarding this public and occupational health threat. Additionally, it was also possible to focus on Aspergillus sections indoors [ 12 , 21 ], as well as other fungal species, providing a more complete fungal characterization with a wider number of different fungal species being identified than the other active and passive sampling methods [ 13 , 14 , 17 , 18 , 20 , 31 ]. Although the bakeries setting presented the highest fungal contamination due to the role as contamination sources of the raw materials [ 10 , 14 ], the setting presenting the highest Aspergillus sp.…”

“…Unfortunately, the section Fumigati was classified based on macroscopic and microscopic characteristics and because of that it was impossible to identify the species among the section. However, in previous studies held by the same team also with environmental isolates from different indoor environments, results revealed a good correlation between phenotypic and molecular identification [19,64]. Further studies should comprehend molecular identification of Aspergillus isolates and cytotoxicity analyses.…”

“…It is also important to have information on the microbiome outdoors in order to determine the origin of azole resistance. Other fungal species observed in VOR media, such as Aspergillus sp., raise concern on the origin of fungal resistance and its implications for human health [8][9][10][12][13][14]58,65,66].…”

“…The fact that they were able to grow in a fixed concentration of posaconazole is of concern for Aspergillus sp. and must be further explored in order to determine fungal susceptibility and consequent risk for the health of house inhabitants, especially if immunocompromised or with respiratory diseases [13,14]. It was possible to obtain information on the housing typologies and characteristics that most influence microbial contamination, including azole resistance.…”
