... Silhavy. Many kinds of bacteria commonly found in liquid environments naturally form biofilms when they meet a solid surface. Biofilms often occur on teeth where, if not removed, they become part of plaque and lead to decay. They also can pose a problem on any artificial surface implanted in the body, such...Research uncovers new treatment target for cystic fibrosis patients lung infection
