Relationship between maternal prenatal psychological distress (SRQ-20) and infant faecal bacterial profiles at 20-28 weeks. Proportions of the A) class Negativicutes, B) order Selenomonadales, and C) family Veillonellaceae observed from faecal specimens collected at 20-28 weeks were inversely correlated with maternal psychological distress (SRQ-20) (p ≤ 0.01). Individual maternal SRQ-20 scores for the 36 infants investigated at 20-28 weeks are represented by circles using a gradient of colours ranging from green (low SRQ-20 scores) to red (high SRQ-20 scores). Blue squares represent the non-parametric regression smoother used to show the trend in the observations.
