MICROBIAL BIOFILM [4 records]

Record 1 2014-09-22

English

Subject field(s)
  • Microbiology and Parasitology
CONT

Oral pathogens are opportunistic in nature and under normal conditions do not cause health problems. Dental plaque is an excellent example of microbial biofilm formation – colonies of bacteria that grow on a surface in a non-sterile, wet environment.

  • Microbiologie et parasitologie
CONT

Les pathogènes de la cavité buccale sont par nature opportunistes et, dans des conditions normales, ne causent pas de problèmes de santé. La plaque dentaire offre un excellent exemple de formation de biofilms microbiens (colonies de bactéries qui prolifèrent à la surface d'un milieu humide non stérile).

Dental plaque is a general term for the diverse microbial community(predominantly bacteria) found on the tooth surface, embedded in a matrix of polymers of bacterial and salivary origin. Plaque is an example of a biofilm...

CONT

La placa dental o placa bacteriana es la principal causante de las enfermedades de la cavidad oral. Esta placa se acumula sobre la superficie del diente y puede ser muy destructiva. La placa dental se compone principalmente de bacterias, alimentos y saliva. Las bacterias que allí se encuentran degradan los restos alimenticios y producen los desechos (ácidos y toxinas) que van destruyendo lentamente los dientes.

Subject field(s)
  • Optics
CONT

The application of confocal laser scanning microscopy(CLSM) has provided a powerful non-destructive method to biofilm research. CLSM application to biofilm work... enabled complex microbial communities to be visualised in-situ revealing their most intricate architecture and organisation without disruption caused by fixation. One major advantage of applying CLSM to biofilm study is its ability to obtain optical thin sections of fully hydrated biofilms. CLSM coupled with fluorescence methods and image analysis provides images with better resolution thus giving more information pertaining to biofilm composition.

French

Domaine(s)
  • Optique
OBS

Le microscope confocal à balayage laser (MCBL) est un microscope optique à éclairage épiscopique géré par un ordinateur qui est capable de sectionner optiquement un échantillon épais. Son image est ensuite reconstruite en superposant toutes ou certaines des sections optiques. [...] L'image résultante obtenue par balayage au niveau du plan focal a une épaisseur extrêmement limitée (section optique) et n'est pas perturbée par des images floues des plans situés au dessus ou au dessous.

OBS

L'image en microscopie confocale correspond à une section optique de l'objet, et l'épaisseur de cette section est d'environ 0,5 à 0,7 µm.
