Short answer

The correct answer is an option (d). All statements are incorrect.

Step-by-step solution

Introduction

• Biofilm is a microbial community bound together by a gummy-textured matrix made mostly of polysaccharides released by the organisms, with some proteins and nucleic acids thrown in for good measure.
• Biofilms usually form on surfaces and adhere to them.

Explanation

Biofilms cause diseases like Legionnaires' disease, otitis media (ear infections), and different disorders in cystic fibrosis sufferers. They generate plaque in the mouth and colonize catheters, prostheses, contact lenses, and internal devices like pacemakers. They form in open wounds and burned tissue as well.

Hence, all the options are correct, so the incorrect statement is an option (d).
