Biofilms are known to be:

The assertion that biofilms are highly susceptible to the body's defense mechanisms is not accurate. In reality, biofilms are known for their resilience and ability to protect the microorganisms within them from both the host's immune system and various forms of treatment, such as antibiotics.

Biofilms consist of complex communities of microorganisms that adhere to surfaces and are encased in a protective matrix. This matrix can make it challenging for the body's immune cells to penetrate and effectively combat these microorganisms. Furthermore, the bacteria within biofilms can exhibit a range of metabolic states, some of which may be more resistant to immune responses.

In contrast, the correct understanding of biofilms highlights their notable resistance to treatments, including antibiotics, due to the protective structure. While they can contribute to infections and other issues, their capability to withstand disinfection processes and rough treatment by the immune system is why they are often associated with chronic infections and treated as a significant concern in both medical and environmental settings.
