Introduction to the Human Microbiota01:22

Introduction to the Human Microbiota

Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity, and disease...
Introduction to Microbial Ecology01:28

Introduction to Microbial Ecology

Microbial ecology examines the complex web of interactions and diversity among microorganisms within various ecosystems. This field seeks to understand how microbial populations adapt to and influence their environments and how these interactions shape broader ecological processes. Microbes are integral to ecosystem function, participating in nutrient cycling, energy flow, and the maintenance of environmental homeostasis.An ecosystem represents a dynamic interaction between living organisms...
Microbial Wastewater Treatment01:30

Microbial Wastewater Treatment

Microbial communities in aquatic ecosystems play a key role in the natural breakdown of contaminants introduced through domestic and industrial effluents. Acting as biological catalysts, these microbes change and mineralize a wide range of organic and inorganic pollutants under different redox conditions.In oxygen-rich surface waters, aerobic heterotrophs lead organic matter breakdown, using oxygen as the terminal electron acceptor to efficiently oxidize substrates to carbon dioxide and water.
Environmental Applications of Microorganisms01:30

Environmental Applications of Microorganisms

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...
Microbiota Modulation by Antibiotics01:21

Microbiota Modulation by Antibiotics

Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
Microbial Interactions: Cooperation01:26

Microbial Interactions: Cooperation

Microbial cooperation involves beneficial interactions in which different species work together for individual or mutual advantage. These interactions can profoundly influence ecological dynamics and evolutionary processes, and they are essential to many pathogenic and symbiotic relationships.Nematode–Bacteria CooperationA striking example is the relationship between the Gram-negative bacterium Xenorhabdus nematophila and the parasitic nematode Steinernema carpocapsae. Juvenile nematodes...

Area of Science:

  • Ecology
  • Microbiology
  • Public Health
  • Environmental Science

Background:

  • The One Health framework integrates human, animal, and environmental health.
  • Current One Health approaches often limit microbial focus to pathogens, zoonotic diseases, and AMR.
  • This narrow scope overlooks the critical ecological roles of microorganisms.

Purpose of the Study:

  • To analyze the historical development of the One Health framework.
  • To identify limitations in its application to the microbial world.
  • To advocate for a more inclusive conceptualization of microorganisms within One Health.

Main Methods:

  • Historical analysis of the One Health framework's evolution.
  • Critical review of current One Health implementation regarding microbes.
  • Development of recommendations for conceptual, metric, and governance shifts.

Main Results:

  • The One Health framework's microbial scope is currently restricted.
  • Microorganisms are essential for ecosystem functioning and life processes.
  • Key gaps exist in conceptualizing and governing microbes within One Health.

Conclusions:

  • Integrating microorganisms as ecologically constitutive is vital for One Health.
  • Recommendations include conceptual shifts, microbial metrics, and microbial governance.
  • A broadened One Health approach strengthens responses to biodiversity loss and climate change.
