Predicted functional genes from the cecal microbiome of PbOAc and SRM 2710a treated mice compared to the cecal microbiome from animals that received no Pb or other metals. The 16 S sequences from the top 20 OTUs contributing most to dissimilarity at the highest dose of PbOAc (25 mg/kg) and SRM 2710a (30 mg/kg) were analyzed using the CLC Genomics Workbench (22.0.2; Microbial Genomics Module) as described. MetaCyc (metacyc.org) (Caspi et al., 2020) and Transform Column-All Ancestors of Entity were used to identify super pathways.
