Search for antimicrobial resistance genes using Abricate v1.0.1 tool, showed differences in the gene patterns (Supplementary Table T3), for example isolates 45A5 (AD lesional), 48 (AD non lesional), 492 (H) and 52B (NH) did not carry the blaZ beta-lactamase gene present in the reference strain ATCC 12228 strain. Here, LACTB is linked to Alzheimer disease.
