Evidence of earthworm gut as a hotspot for the dispersal of tetracycline-resistant genes: A feeding experiment with tetracycline-resistant bacteriome based on midgut fluid sensitivity

We constructed diets treated by tetracycline-resistant bacteriome with varying susceptibility to midgut fluids of earthworms, and investigated the fate of bacterial communities and TRGs (including tetB, tetC, tetZ, tetL, and tetX) and their response to tetracycline (TC) during earthworm conversions in an artificially controllable environment
