Question

A biofilm consists of bacterial populations adhering to host cells and are embedded in a common capsular mass?

Answer 1

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.
