Composition of the fecal microbiota in antibiotic exposed and unexposed mice throughout life

The composition of microbiota in unexposed mice (no ABX, n=20) and mice exposed to antibiotics in early life (n=20) was profiled using 16S rRNA gene sequencing of DNA extracted from pooled fecal samples collected at specific intervals from 1 week post-antibiotic exposure (week 4 of age) to week 102 of life. Two distinct microbiota community types were evident: post-antibiotic exposure (PAM I and PAM II, n=10/group).
