NEET BIOLOGY

Detailed explanation-1: -The human gut microbiota is mostly composed by two dominant bacterial phyla, Firmicutes and Bacteroidetes that represent more than 90% of the total community, and by other subdominant phyla including Proteobacteria, Actinobacteria, and Verrucomicrobia [2].

Detailed explanation-2: -The most commonly seen phyla in a typical gut microbiome include Bacteroidetes, Firmicutes, Actinobacteria, Proteobacteria, and Fusobacteria which constitute >90% of the gut microbiota.

Detailed explanation-3: -The dominant gut microbial phyla are Firmicutes, Bacteroidetes, Actinobacteria, Proteobacteria, Fusobacteria, and Verrucomicrobia, with the two phyla Firmicutes and Bacteroidetes [13] representing 90% of gut microbiota.

Detailed explanation-4: -What are Bacteroidetes and Firmicutes? While genera of bacteria like Bifidobacteria and Lactobacillus might be familiar to you, they only make up a small percentage of your gut microbiome. Bacteroidetes and Firmicutes are the two major bacterial phyla that account for about 90% of your gut microbiota.

Detailed explanation-5: -The Firmicutes are a dominant phylum within the intestinal microbiota that are capable of producing resistant endospores that maintain viability within the environment and germinate within the intestine to facilitate transmission.
