yes no context dependent unknown
Clinical Rolescommensal; probiotic candidate
AMR Highlights intrinsic glycopeptide resistance (vancomycin; lacks acquired vanA/vanB/vanC genes)
Clinical Associations:
E1
E3 — Strong human clinical evidence E2 — Moderate human evidence E1 — Limited / preliminary
Bifidobacterium species display intrinsic vancomycin resistance but lack acquired resistance genes (vanA, vanB, vanC) and have fewer reported associations with bloodstream infections compared to Lacticaseibacillus spp., suggesting a relatively lower BSI risk profile for immunocompromised patients receiving Bifidobacterium-containing probiotics.
