Results from this study support previous studies which reported large populations or Bacteroidetes (including the families Bacteroidaceae
and Porphyromonadaceae) and Firmicutes (including the families Clostridiaceae and Lachn.ospiraceae) present within the digestive tract, as well as organisms from the phyla Proteobacteria (including the families Enterobacteriaceae and Aeromonadaceae) and Verrucomicrobia.
Overall, patients with MS usually have gut dysbiosis and often reduced numbers of Faecalibacterium, Bacteroidaceae, and Prevotella.
Patients with MS can exhibit gut microbial dysbiosis, with increases in Methanobrevibacter Akkermansia , Desulfovibrionaceae , Actinobacteria, Bifidobacterium, Streptococcus , Firmicutes, Euryarchaeota , Ruminococcus , Pseudomonas, Mycoplana, Haemophilus, Blautia, and Dorea  and decreases in Butyricimonas , Lachnospiraceae, Ruminococcaceae , Faecalibacterium, Prevotella, Anaerostipes, Clostridia XIVa and IV Clusters , Fusobacteria , Bacteroidaceae , C.
