Protozoa-enhanced conjugation frequency alters the dissemination of soil antibiotic resistance.

Protozoa, as primary predators of soil bacteria, represent an overlooked natural driver in the dissemination of antibiotic resistance genes. However, the effects of protozoan predation on antibiotic resistance genes dissemination at the community level, along with the underlying mechanisms, remain unclear. Here we used fluorescence-activated cell sorting, qPCR, combined with metagenomics and reverse transcription quantitative PCR, to unveil how protozoa (Colpoda steinii and Acanthamoeba castellanii) influence the plasmid-mediated transfer of antibiotic resistance genes to soil microbial communities.
