Gut microbiota contribute to host health. Numerous recent studies have focused on the survival and reproduction of nontarget soil animals exposed to the toxicity of silver nanoparticles (AgNPs) but changes in the gut microbiota due to nanoparticle toxicity are largely unknown. Here, we examine some effects of AgNPs and silver nitrate (ionic Ag) on the gut microbiota of the common soil collembolan Folsomia candida using Illumina sequencing and concomitant changes in antibiotic resistance genes (ARGs) of the gut microbiota using high-throughput quantitative PCR. A large number of Ag accumulated in Ag-exposed individuals after 28 days and ionic Ag significantly inhibited the reproduction of the..View full abstract
