Within this module we are analysing the bacterial composition of the gut microbiome from mothers and their children. Our aim is to investigate the impact of maternal obesity towards the infant gut microbiome, as well addressing the question how strong the composition is influenced by vertical transfer from mother to child. The main focus of this project is to determine possible risk associated bacteria, which are relevant in the infant gut microbiome. The prospective stool sampling from the mothers helps to analyse the inter-individual variation as well as the influence of diet towards the human gut. Additionally, the oral microbiome of the children is going to be analysed since the microbiome of the children is influenced by bacteria of the mouth cavity.
