Does next-generation DNA sequencing reveal that low fungal diversity in house dust is associated with childhood asthma development?
Early life exposure to low fungal diversity in house dust was associated with increased risk for later asthma developmen tin this low-income, immigrant community. No individual fungal taxon (species, genus, or class) was associated with asthma development, although exposure to low diversity within the genus Cryptococcus was associated with asthma development. Future asthma development studies should incorporate fungal diversity measurements, in addition to measuring individual fungal taxa. These results represent a step toward identifying the aspect(s) of indoor microbial populations that are associated with asthma development and suggest that understanding the factors that control diversity in the indoor environment may lead to public health recommendations for asthma prevention in the future.
: Based on moderate levels of correlations on most HF symptoms in this study, the CG as proxy appears to be a reasonable substitute for patient responses in a community setting. However, greater family preparation for symptom assessment is warranted to improve congruence for future symptom assessment.
