Table 4.
Number of discriminatory operational taxonomic units (OTUs) found to be significantly different (q-value < 0.05) in relative abundance in infant stool samples at 1 month or 6 months based on maternal group B Streptococcus (GBS) status, after adjusting for maternal race, prenatal antifungal use and intrapartum antibiotic use. Family is presented in order of overall abundance (higher to lower), by time of sample.
