What is meant by dysbiosis?

2 Dysbiosis. 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.

How does microflora protect from disease?

Intestinal bacteria play an important role in the development of the immune system. The normal intestinal flora is responsible for resistance to colonization by exogenous pathogenic microorganisms. Nevertheless, it also constitutes a reservoir of potentially pathogenic bacteria in close contact with the host.

How does the microbiota affect the human body?

What is the role of gut microflora in immunity?

What is the benefit of intestinal microflora?

These intestinal microflora can benefit health by breaking down toxins, synthesizing vitamins, and defending against infection. But they also play a role in such diseases as peptic ulcers, diarrhea, colorectal cancer, and inflammatory bowel disease.
