NEET BIOLOGY

Detailed explanation-1: -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-2: -Below the bladder, the normal microbiota of the male urogenital system is found primarily within the distal urethra and includes bacterial species that are commonly associated with the skin microbiota. In women, the normal microbiota is found within the distal one third of the urethra and the vagina.

Detailed explanation-3: -The analysis report of human microbiomes of over 690 have shown that a large number of bacteria of the gut microbiome were mainly from four major phyla: Bacteroidetes, Actinobacteria, Firmicutes and Proteobacteria (Grice and Segre 2012); (Belizário and Napolitano 2015).

Detailed explanation-4: -In a healthy person, these “bugs” coexist peacefully, with the largest numbers found in the small and large intestines but also throughout the body. The microbiome is even labeled a supporting organ because it plays so many key roles in promoting the smooth daily operations of the human body.
