Concept explainers
Concept introduction:
Biofilms are the colonies formed by different species of bacteria. These colonies are initiated by one bacterium that attaches to the surface of vulnerable body parts, likea tooth or lung tissue. The other microbes subsequently attach to either the first bacterium or the inevitable sugar and protein secretions by it.
Biofilms are present in almost every natural environment, and it is an adaptation strategy of bacteria for the sustenance of their lives. The different species of bacteria cooperate and interact with each other while forming biofilms, and functioning in these colonies.
Biofilms are also involved inthe passing of genetic material from one microbe to its neighboring microbe. Therefore, they can cause infections and also develops resistance to antimicrobials.
