80% of microbes exist under form of biofilms


Formation-biofilm-EN

Bacterial biofilms are complex entities: these are microbial populations (bacteria, fungi, algae,…) clinging to a surface and coated with a matrix of exopolysaccharides (sugar polymer).
They can be observed on many humid surfaces:

  • Biotic such as mucous or wound cells
  • Or abiotic such as walls, floors or equipment.

They allow the adaptation of bacteria to their environment as their formation aims at protecting them from any stress.

On farms, biofilms are affecting both public and animal health. They are indeed involved in many pathologies (mastitis, pneumonia, paratuberculosis, enteritis, wound infection….) and consequently associated to significant economic losses. In abiotic environments, biofilms are sources of many pathogens causing intoxications (E. coli, Listeria monocytes, campylobacter jejuni…).

Biofilm development is divided in 3 steps:

  1. Attachment to the surface
  2. Maturation and growing
  3. Dispersion to colonize new area.

This process is controlled, cells are able to share some information: quorum sensing.

Bacteria inside biofilm develop avoidance strategies, whether in the environment or hosting on the animal. Biofilms act as shields, resistant to biocides, host immunity, even antibiotics. This enables the bacteria development and disease outbreak. New strategies of biofilm control are being developed such as essential oils, enzymes and biocompatible grafted surfaces.
