The relative abundance of antimicrobial resistance genes is different at 6 weeks and 1 year. MaAsLin2 was used to test if the compositional relative abundance of ARGs varied by postnatal age of the infant, delivery mode, feeding mode, gestational age at birth, infant sex, and antibiotic use during the infant’s initial hospitalization. Using a multiple hypothesis correction [Benjamini-Hochberg q < 0.01], 81 antimicrobial resistance genes were differentially abundant between the 6-week and 1-year time points. Antimicrobial resistance genes are colored by mechanism of antibiotic resistance (antibiotic efflux or not) with a greater proportion of genes that work through antibiotic efflux at 6 weeks (chi-square test p < 0.01)
