A prospective observational study in infants with biliary atresia and controls to determine whether the composition of the intestinal microbiome is specific for biliary atresia will be conducted. The hypothesis of the study is "infants with biliary atresia have a unique microbiome signature at the time of diagnosis and changes in population dynamics occur during disease progression". The microbiome will be determined at diagnosis and at well-defined time points during the natural history of the disease.
