Assessment of AR in fecal samples from baby Q between the newborn stage and 4 months of age. (A) Black bars, total bacterial counts on CBA plates; gray bars, total bacterial counts on MAC plates. (B) Black bars, Erm^r bacterial counts on CBA plates; white bars, Erm^r bacterial counts on MAC plates; gray bars, copy numbers for ermB gene by real-time PCR. (C) Black bars, Tet^r bacterial counts on CBA plates; white bars, Tet^r bacterial counts on MAC plates; gray bars, copy numbers for tet(M) gene by real-time PCR. Real-time PCR was performed on two independent DNA extract replicates, and the coefficients of variation for log copy numbers of resistance genes were <0.05.
