Arsenic-driven taxonomic shifts are partially reversed by L. plantarum ATCC 14917 and correlate with behavioral outcomes
This study investigates how subchronic arsenic exposure alters the gut microbiome and whether supplementation with Lactobacillus plantarum ATCC 14917 can reduce arsenic-associated dysbiosis. Fecal samples from control, arsenic-exposed, and arsenic plus probiotic-treated mice were analyzed using 16S rRNA gene amplicon sequencing to evaluate microbial diversity, community structure, and taxonomic shifts.
