Bacteroidetes, Ruminococcus gnavus, and Fusobacterium were increased in patients with GAD compared with controls, while Faecalibacterium, Eubacterium rectale, Sutterella, Lachnospira, and Butyricicoccus were increased in healthy controls.
Specifically, the whole-grain diet gave a moderate boost to populations of beneficial Lachnospira bacteria, which make protective short-chain fatty acids and help counteract another bacterial species that contributes to inflammation.
Tremlett conducted three experiments in pediatric MS and found that Firmicutes, Archaea Euryarchaeota, and Proteobacteria (Desulfovibrionaceae) increase in patients with MS, while Lachnospira (Lachnospiraceae), Verrucomicrobia (Ruminococcaceae), and Fusobacteria decrease, and MS in children with the absence (versus presence) of Fusobacteria was associated with relapse risk [132-134].
Using gene functional classification in a metagenomic analysis of gut contents samples from yaks, we detected sequences homologous to genes coding 1,4-beta-cellobiosidase (EC 3.2.1.91) (46 genes), (3-glucosidase (EC 3.2.1.21) (45,090 genes), 1,4-[beta]-xylosidase (EC 3.2.1.37) (608 genes), and endo-1,4-[beta]-xylanase (EC 3.2.1.8) (6,656 genes), which participate in the digestion of cellulose and hemicellulose, indicating that quite a few gut microbes, including the genus Clostridium, Lachnospira, and Ruminococcus, play important role in digesting cellulose in yaks.
Finlay and his colleagues identified a transient imbalance early in life in children with atopy, wheeze, and asthma of four specific bacterial taxa: Faecalibacterium, Lachnospira, Veillonella, and Rothia.
The relative abundance of the bacterial genera Lachnospira, Veillonella, Faecalibacterium, and Rothia seems significantly decreased in children at risk of asthma, with consequent reduced levels of fecal acetate and dysregulation of enterohepatic metabolites [31].

At the genus level, the composition of Blautia was increased in T1DM group than control group whereas the composition of Haemophilus, Lachnospira, Dialister, and Acidaminococcus was decreased.
At the genus level, the 5 most abundant genera in the Before sample were Faecalibacterium, Roseburia, Lachnospira, Subdoligranulum, and Blautia.
Bacteria of the genera Bacteroides, Prevotella, Ruminobacter, Fibrobacter, Methanobrevibacter, Methanomicrobium and Clostridium (spores) are rod-shaped; Butyrovibrio, Selenomonas and Lachnospira are curved rod bacteria; cocci indicate the presence of Ruminococcus, Streptococcus and Megasphaera.
In contrast, Firmicutes of the class Clostridia are depleted in alcoholics but are not significantly changed in the cirrhosis group, with the exception of Veillonellaceae, which is increased and Lachnospira, which is decreased (table 1).
