Biofilms

263
Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...

Summary

Bacterial biofilms and non-attached aggregates are crucial for bacterial survival and transmission. The proposed "One Biofilm" concept links these formations across humans, animals, and the environment, mirroring the One Health initiative.

Area of Science:

  • Microbiology
  • Environmental Science
  • One Health

Background:

  • Bacterial biofilms are surface-attached communities protected by a polymer matrix.
  • Non-attached bacterial aggregates share phenotypes with biofilms and are also widespread.
  • Both structures are found in diverse natural and clinical settings.

Purpose of the Study:

  • To propose the
  • One Biofilm
  • concept, linking bacterial biofilm and aggregate formation across different hosts and environments.
  • To highlight the potential role of biofilms/aggregates in bacterial persistence and transmission.
  • To connect bacterial biofilm dynamics to the broader One Health framework.

Main Methods:

  • Literature review and conceptual synthesis.
  • Comparative analysis of biofilm and aggregate phenotypes.
  • Integration of findings within the One Health framework.

Main Results:

  • Biofilm and aggregate formation are ubiquitous and critical for bacterial lifecycle stages.
  • These structures are vital for bacterial persistence within hosts and in the environment.
  • Biofilm/aggregate formation is proposed as a unifying factor in the One Health concept.

Conclusions:

  • The
  • One Biofilm
  • concept offers a new perspective on bacterial ecology and epidemiology.
  • Biofilm/aggregate formation is crucial for bacterial persistence and transmission, linking microbial communities across One Health domains.
  • Understanding these structures is key to addressing infectious diseases and environmental health challenges.
