Question
Chapter 4, Problem 8RQ
Summary Introduction
To review:
The importance features of biofilms.
Introduction:
The bacterial cells are of various shapes and sizes such as coccus, spiral, comma, and spherical. The size of the bacteria also varies from 0.2 micrometers to 10 microns. The bacterial cell communicate with each other through means of various techniques such as quorum sensing.

Describe a detrimental and a beneficial effect of biofilms.
Explain the formation of biofilm.
Diseases that involve biofilm-producing bacteria are of serious concern. They are not as easily treated compared with those involving free-floating (or planktonic) bacteria. Explain three reasons why biofilms can be more pathogenic.
