Which of the following is NOT a characteristic of bio-films?

• A. Formed by a single species of bacteria
• B. Can trap other microorganisms
• C. Can attach to inert surfaces
• D. Consist of micro-colonies

Answer: (A)

Biofilms are complex communities of microorganisms that adhere to surfaces and are encased in a self-produced extracellular matrix. One important characteristic of biofilms is that they typically consist of multiple species of bacteria and other microorganisms rather than being formed by a single species. This diversity allows biofilms to thrive in various environments and enhances their resilience against adverse conditions, such as antibiotics and disinfectants. The other characteristics mentioned are indeed aspects of biofilms. They are capable of trapping a variety of microorganisms, which can lead to a diverse community within the biofilm. Additionally, biofilms can attach to inert surfaces, such as pipes, medical devices, and natural substrates, allowing them to establish in numerous settings. The structure of a biofilm often includes micro-colonies, which are clusters of cells within the biofilm matrix. Understanding these characteristics is essential for comprehending how biofilms develop, function, and impact various environments, especially in fields related to health and sanitation.
