Big Bad Biofilms: How Communities of Bacteria Cause Long-Term Infections
Bacteria are tiny living things that like to attach to surfaces. Most bacteria are harmless, but if the wrong kind of bacteria get into the human body where they do not belong, they can cause an infection. Infections make the human body very sick. Most infections can be cured by antibiotics, but not infections caused by biofilms! Biofilms are communities of bacteria living together and covered in protective sticky goo, and most medicine does not work against them. Here we explain how biofilms protect bacteria from antibiotics, and what we can do to fight these long-term infections.
