NEET BIOLOGY

Detailed explanation-1: -Dysbiosis refers to the imbalance of microbial species due to a reduction in microbial diversity within certain bodily microbiomes. Beneficial bacteria are usually minimized, whereas other harmful bacteria increase in number.

Detailed explanation-2: -Dysbiosis (also called dysbacteriosis) is characterized by a disruption to the microbiome resulting in an imbalance in the microbiota, changes in their functional composition and metabolic activities, or a shift in their local distribution.

Detailed explanation-3: -Dysbiosis is often defined as an “imbalance” in the gut microbial community that is associated with disease. This imbalance could be due to the gain or loss of community members or changes in relative abundance of microbes.

Detailed explanation-4: -The gut microbiota is proposed to shape the host immunity and maintain homeostasis, through complex microbial cross-talk with the mucosal immune system that involves a variety of highly integrated signaling pathways and gene regulatory networks.
