Fig. 2From: Gut microbiome and plasma metabolome changes in rats after oral gavage of nanoparticles: sensitive indicators of possible adverse health effectsScatter plots obtained for selected most abundant genera after exposure either to Ag or to SiO2. VC, vehicle control; Ag50, Ag nanoparticles (100 mg/kg body weight/day); SiO2, SiO2 nanoparticles (1000 mg/kg body weight /day); The median relative abundance of the selected genera displayed was ≥ 0.2% in at least one group (further abundant genera are shown in Fig. S4 (Additional file 1). p values were obtained by Mann–Whitney-U-test. N = 5 for each groupBack to article page
