Microbiome development in preterm infants below 33 gestational weeks
16S rRNA gene bacterial profiling of stool samples from preterm infants in early life. Samples were collected longitudinally from 86 infants at three defined time points (TP1: first week of life; TP2: one month; TP3: 1-year corrected age) to analyze the development of the microbiome and its interaction with the immune system.
