Infant fecal metagenome in eczema, case-control, Singapore

Infant fecal microbiome related to eczema

Case-control study of 12 infant fecal samples from Singapore (9 with location recorded), comparing stool microbiota gene composition between 6 samples from healthy controls and 6 from infants with allergy or atopy, in relation to eczema development. machine-written summary

! Self-contradictory metadata

country: supplementary table and GMrepo disagree for 7 samples (e.g. MY vs SG) — withheld.

The sources disagree on 7 samples. Where two incompatible values exist for one sample (or one person's samples disagree on sex), neither value is published: the field is left empty here, in the sample sheet and in the downloads. Both sides, with their sources, are in gut_metadata_contradictions.parquet of the data package (what counts as a contradiction).

Archive description

Eczema is common chronic inflammatory skin disorder with significant impact on child health, and its prevalence is increasing worldwide. It is known that the interaction between gut microbes and the host immune system influences early life development of the immune system. We and others have shown that the composition of the stool microbiota signatures differ between eczema and healthy controls in infancy. The scope of work will include the identification of functional and structural gene composition present in the stools of infants with and without eczema by comparative metagenomics. The proposed study will provide the initial steps towards a comprehensive evaluation of the bacterial gene composition in stool microbiota in relation to development of eczema.
