Microbial abundance analysis also showed that Alistipes finegoldii, Alistipes shahii, and Bifidobacterium adolescentis were depleted in both Lcn-2-low and Lcn-2-high MS patients, whereas Anaerobutyricum (Eubacterium) hallii, Blautia massiliensis, Clostridium hylemonae, and Roseburia sp 32368 were depleted only in MS Lcn-2-high patients (Figure 6B and Supplementary Figure 3). The gene discussed is LCN2; the disease is myeloid sarcoma.
