Metagenomic DNA was isolated from 535 colon content samples, and quantitative PCR assays were performed to assess the abundances of the following 10 antimicrobial resistance genes aac(6'-Ie-aph(2″)-Ia, aadA1, blaCMY-2, blaCTX-M, blaKPC-2, erm(, mecA, tet(A), tet(, and tet(M). For colon contents, only TETrE. coli (P 0.01), 3GCrE. coli (P 0.01), and erm( (P = 0.03) levels were higher in conventional than in organic cows. Sampling day also significantly affected (P 0.01) these levels. Production system did not
