Childhood antibiotic treatments reduce diversity, stability of intestinal microbiota

A project followed the development of 39 Finnish infants from birth to the age of three. Half of the children received 9-15 antibiotic treatments during the research period, and the other half did not receive any such treatments. Stool samples were collected from the children monthly between the ages of 2 and 36 months, for a total of 1069 samples.
