The proportion of the resistance determinants erm(X), sul2, tet(H), tet(M), and tet(W) to 16S rRNA gene copies in nasopharyngeal samples within each treatment group at days 0, 5, 12, and 34. Different lowercase letters within each sampling time represent significantly different means (P < 0.05). Error bars indicate ± standard error of the mean (n = 12)
