Figure 5From: Longitudinal characterization of antimicrobial resistance genes in feces shed from cattle fed different subtherapeutic antibioticsRepresentative DGGE profiles generated from PCR-amplified 16S-rRNA in fecal deposits from the control group of cattle. DNA from replicate fecal deposits (N = 3) were pooled for analysis. The time points were days (d) 7, 28, 56, 98, 112, and 175. M, marker used to normalize gels consisted of pooled DNA from all treatments on days 7 and 175.Back to article page
