A biofilm consists of bacterial populations adhering to host cells and are embedded in a common capsular mass?
The statement is true.
The biofilm is defined as which consists of layers of bacterial
population which are adhering to the host cells and are embedded in
a common capsular mass.
The first formed step is the pellicle in the maturation of plaque
in the mouth and in pellicle the bacterial population and increases
which can lead to formation of biolfilm and ultimately plaque. It
is slimy in consistency. The microorganisms are enclosed in the
extra cellular capsule matrix
The biofilm appears in the mouth within 30 minutes of the brushing
period. The bacteria in the plaque formation are categorised as the
early and the late colonisers. Example for early colonisers can be
streptococcus sanguis, s. oralis etc and the late colonisers can be
campylobacter rectus, porphyromonas etc.
The biofilm or the plaque can be seen with the staining agents like
erythrosun dyes commonly known as plaque staining agents.
The plaque may eventually mature to calculus if not cleaned.
