“…Regarding the disastrous heavy rainfall that occurred in Western Japan in 2018, Oda et al reported that Legionella pneumonia occurred during recovery work, possibly caused by exposure to water and soil after the flood disaster (5). In addition, Oshikata et al reported a case of allergic bronchopulmonary mycosis that developed due to exposure to Eurotium herbariorum after the Great East Japan Earthquake, in which mycofloral surveillance was performed and high counts of Eurotium were detected (6). The present case seems to be similar and interesting in that the presence of the antigen was proven through an environmental survey.…”

“…Due to allergen avoidance through environmental improvement after floods, asthma symptoms in children diminished [31] and respiratory function increased [32]. Similarly, we reported in case presentation that the temporary housing environment in Ishinomaki city has improved greatly, thereby decreasing fungal exposure and ameliorating symptoms of allergic bronchopulmonary mycosis [21]. A meta-analysis showed that bronchial hyperresponsiveness decreased after mite-impermeable mattress covers were provided to patients previously exposed to high levels of Der 1 [33].…”

“…In addition, a nuclear accident at the Fukushima Daiichi Nuclear Power Plant after the earthquake and tsunami forced an evacuation, and levels of indoor airborne fungi were found to be increased in the evacuation zone [20]. We previously reported a rare case of allergic bronchopulmonary mycosis in a patient exposed to the fungusEurotium herbariorum while living in post-earthquake temporary housing in Ishinomaki [21].…”

Background: We previously reported increased prevalence of asthma in adults who lived in temporary housing after the 2011 Great East Japan Earthquake. To investigate changes in asthma prevalence and mite-specific immunoglobulin E (IgE) titers in temporary housing residents from 2014 through 2019. Methods: We diagnosed asthma in Ishinomaki city temporary housing residents (age, ? 15 years) by using the GINA guidelines. We analyzed serum antigen-specific IgE levels to Dermatophagoides farinae (Der f), Dermatophagoides pteronyssinus (Der p), and Aspergillus fumigatus. Results: The prevalence of asthma exceeded 20% across all age groups throughout the study period. The proportion of study participants with a 'positive' antigen-specific IgE titer (i.e., ? 0.35 IUA/mL) was higher in asthmatics than in non-asthmatics for Der f and Der p but not for Aspergillus fumigatus. Residents ? 50 years old who diagnosed asthma or non-asthma, the percentage with Der f -specific IgE titer ? 0.10 IUA/mL was higher than in those with ? 0.35 IUA/mL. Among study participants, asthma onset occurred before the earthquake, during residence in shelters or temporary housing, and, after 2016, moving out of temporary housing.The Der p-specific IgE level was positively correlated with the duration of temporary housing (P < 0.05, r = 0.41) and inversely correlated with the time elapsed since moving out of temporary housing (P < 0.05, r = -0.35). Conclusions: Mite allergen sensitization was found in non-asthmatic temporary housing residents after the 2011 Japan earthquake and tsunami; asthma developed even after subjects moved out of temporary housing.

“…Fungal community analyses in households have begun to attract attention because fungi are now generally considered to be allergens [ 5 , 6 ]. Many researchers have previously reported cases of patients with asthma, allergic bronchopulmonary mycosis (ABPM) and other illnesses caused by fungal products [ 7 , 8 ]. Currently, the culture method remains the primary approach used to conduct fungal community analysis for dwellings [ 9 , 10 , 11 ] and the application of molecular methods, including the NGS method, remains limited because the sequence registrations for fungi in databases are incomplete, and the procedures and methods used to identify fungal sequences have not yet been standardized [ 12 ].…”

Fungal community analyses in homes have been attracting attention because fungi are now generally considered to be allergens. Currently, these analyses are generally conducted using the culture method, although fungal communities in households often contain species that are difficult to culture. In contrast, next-generation sequencing (NGS) represents a comprehensive, labor- and time-saving approach that can facilitate species identification. However, the reliability of the NGS method has not been compared to that of the culture method. In this study, in an attempt to demonstrate the reliability of this application, we used the NGS method to target the internal transcribed spacer 1 (ITS1) in the fungal genome, conducted fungal community analyses for 18 house-dust samples and analyzed fungal community structures. The NGS method positively correlated with the culture method regarding the relative abundance of Aspergillus, Penicillium, Cladosporium and yeasts, which represent the major fungal components found in houses. Furthermore, several genera, such as Malassezia, could be sensitively detected. Our results imply that the reliability of the NGS method is comparable to that of the culture method and indicates that easily available databases may require modifications, including the removal of registrations that have not been sufficiently classified at the genus level.
