Individual preterm infant microbial genus composition by gestational age and STS exposure. (A) Individual microbial repertoires of infants’ ≤32 weeks of gestational age at sampling and > 32 weeks of gestational age of sampling by exposure to STS or non-STS care. Infants exposed to formula (F) feeding or vaginal (V) delivery are identified. The predominant genus are Streptococcus (dark blue), Staphylococcus (red), Pseudomonas (green), and unclassified genus (tan). (B) Boxplot demonstration of major genera differences in STS-exposed and non-STS-exposed infants at corrected gestational age of sampling.
