Fighting bacteria with mucus

Study shows that key proteins in mucus prevent bacterial adhesion to surfaces, could help prevent growth of biofilms.

Slimy layers of bacterial growth, known as biofilms, pose a significant hazard in industrial and medical settings. Once established, biofilms are very difficult to remove, and a great deal of research has gone into figuring out how to prevent and eradicate them.

Results from a recent MIT study suggest a possible new source of protection against biofilm formation: polymers found in mucus. The MIT biological engineers found that these polymers, known as mucins, can trap bacteria and prevent them from clumping together on a surface, rendering them harmless.
