characterize the relationship between
diet, microbiota and host phenotype

identify complex, non-linear relationships
between components of a biological system

problem

a client asked COSBI to investigate the effect of breastfeeding and formula feeding on infant microbiome

solution

by applying a network-based systems biology approach via enrichment of microbial species with host genes we determined the relationship between microbiota and host under different feeding conditions

outcome

a biological interpretation of the results led us to uncover that there is co-expression of more genes in breast-fed samples but lower microbial diversity compared to formula-fed
