Biofilms

241
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...

Bacterial Phylum Actinobacteria

Coryneform bacteria are gram-positive, aerobic, nonmotile rods that exhibit irregular, club-shaped, or V-shaped arrangements. Their V-shape results from snapping division, where the inner cell wall layer forms the cross-wall, while the outer layer remains intact until it ruptures on one side, causing the daughter cells to bend away.The primary genera are Corynebacterium and Arthrobacter. Corynebacterium includes diverse species, ranging from saprophytes to pathogens like Corynebacterium...

Area of Science:

  • Food microbiology
  • Bacterial pathogenesis
  • Biofilm formation

Background:

  • Campylobacter is a leading cause of foodborne gastroenteritis globally.
  • Its presence in the food chain contrasts with its fastidious laboratory growth requirements.
  • Biofilm formation is a proposed mechanism for Campylobacter persistence.

Purpose of the Study:

  • To review Campylobacter biofilm characteristics.
  • To identify factors influencing biofilm formation.
  • To discuss control strategies for Campylobacter biofilms.

Main Methods:

  • Literature review of Campylobacter biofilm research.
  • Analysis of factors affecting biofilm formation (biological and environmental).
  • Discussion of current and potential control strategies.

Main Results:

  • Campylobacter biofilm formation varies by strain and is influenced by co-cultivated bacteria.
  • Extracellular polymeric substances (EPS) in biofilms include carbohydrates and eDNA.
  • Biofilm formation depends on factors like flagella, quorum sensing, and environmental conditions.

Conclusions:

  • Campylobacter biofilm research is emerging.
  • Future research should explore dormancy, antimicrobial resistance, and in vivo characteristics.
  • Targeting quorum sensing may offer indirect control strategies.
