Vulnerability of the industrialized microbiota

Area of Science:

• Microbiology
• Ecology
• Human Health

Background:

• The human body hosts a complex microbial ecosystem, the microbiota, crucial for health.
• Global lifestyle shifts and interventions like antibiotics have significantly altered gut microbiota composition.
• These alterations may lead to a loss of microbial functions detrimental to human health, particularly in industrialized societies.

Purpose of the Study:

• To highlight the impact of modern lifestyle changes on the human gut microbiota.
• To propose the application of ecological principles for studying and conserving the human microbiota.
• To underscore the potential negative health consequences of microbiota dysbiosis.

Main Methods:

• Review of current understanding of human microbiota composition and function.
• Analogy drawn from macroecology and conservation science for microbiota research.
• Discussion of factors influencing microbiota alteration, including antibiotics and diet.

Main Results:

• Significant shifts in gut microbiota are observed globally due to lifestyle changes and medical practices.
• Loss of microbial diversity and function may result in suboptimal health outcomes.
• Current microbiota changes might be irreversible, posing long-term health risks.

Conclusions:

• Human microbiota is undergoing detrimental changes due to modern environmental and lifestyle factors.
• Ecological approaches offer a valuable framework for understanding and protecting the human microbiota.
• Proactive research and conservation strategies are needed to safeguard microbial ecosystems for human health.
