Effects of dietary components on antibiotic resistance using mechanistic and plasmid based studies
… attributed to the already resident community of beneficial bacteria. Changes in the abundance of the resistome was observed at day 27, which may be the result of MRF, but high levels of variability were noted within the sampled groups. A study incorporating both metagenomic and plasmid based …
