An in vitro study to assess the impact of tetracycline on the human intestinal microbiome.

ABSTRACT: The human intestinal microbiome, a generally stable ecosystem, could be potentially altered by the ingestion of antimicrobial drug residues in foods derived from animals. Data and the scientific published literature on the effects of antimicrobial residues on the human intestinal microbiome are reviewed by national regulatory authorities as part of the human food safety evaluation of veterinary antimicrobial agents used in food-producing animals. In this study, we determined if tetracycline, at low residue concentrations, could impact the human intestinal microbiome structure and the resistance-gene profile, following acute and subchronic exposure. The effects of 0.15, 1.5, 15, and 150 μg/ml of tetracycline, after 24 h and 40 days of exposure, in 3% human fecal suspensions, collected from
