Compare with Definitions
Biofilm
A biofilm comprises any syntrophic consortium of microorganisms in which cells stick to each other and often also to a surface. These adherent cells become embedded within a slimy extracellular matrix that is composed of extracellular polymeric substances (EPSs).
Plaque
An ornamental tablet, typically of metal, porcelain, or wood, that is fixed to a wall or other surface in commemoration of a person or event.
Biofilm
A complex structure adhering to surfaces that are regularly in contact with water, consisting of colonies of bacteria that secrete a mucilaginous protective coating in which they are encased. Biofilms, which are resistant to antibiotics and disinfectants, corrode pipes and cause diseases such as lung infections, but they can be used beneficially to treat sewage, industrial waste, and contaminated soil.
Plaque
A sticky deposit on teeth in which bacteria proliferate
Plaque around gum margins can lead to gingivitis
Biofilm
A thin film of mucus created by and containing a colony of bacteria and other microorganisms.
