From: The premature infant gut microbiome during the first 6 weeks of life differs based on gestational maturity at birth

Exposure Frequency
Newborn antibiotic exposure 16/17 subjects (94%)
Antibiotic exposure on day of sample collection 14/65 samples (22%)
Delivery mode (# C-sections/total) 13/17 subjects (76%)
Breastmilk exposure at time of sample collection 61/65 samples (94%)

  1. Newborn antibiotics are antibiotics given to the infants in the first few days of life. A stool sample was considered to have antibiotic exposure if antibiotics were administered on same day as sample collection. Delivery mode was either a C-section (Cesarean section) or a vaginal delivery. Breastmilk exposure at time of sample collection was if the child was receiving breastmilk at time of stool collection. A stool sample was considered to belong to an infant who was exclusively fed breastmilk if no milk fortifier or formula was given before or on day of stool sample collection.
