Key Concepts

Human Microbiome

The human microbiome refers to the collective genome of all microorganisms living on and within the human body. A balanced microbiome is essential for overall health, supporting various functions from digestion to immune defense, and disruptions in this balance can lead to increased susceptibility to infections and other health issues.

Competitive Exclusion

Competitive exclusion is a principle in microbial ecology where beneficial resident bacteria inhibit the growth of pathogenic organisms by out-competing them for resources such as nutrients and space. This mechanism helps reduce the likelihood of infections by preventing disease-causing bacteria from establishing themselves.

Resident Bacteria

Resident bacteria are microorganisms that naturally inhabit the human body, especially in areas like the gastrointestinal tract. They are part of the normal microbial flora that plays a crucial role in maintaining health by aiding in processes such as digestion, nutrient absorption, and immune system regulation.
