Biofilm
This is an
SEM micrograph of a Biofilm. The
biofilm was created by a bacterial colony which formed on a silicon device. A small colony of spherical Cocci type bacteria can be
seen forming on the surface of this well developed biofilm. The biofilm
is an adhesive matrix excreted by the colony of bacteria living on the
device. The film is a polymeric compound called EPS (Extracellular
Polymeric Substance). If you look carefully at the edge of the biofilm,
you can see spherical Cocci type bacteria. Some researchers suggest that
a polymeric matrix such as this one can play a role in the antibiotic
resistant nature of some bacterial infections. |
