Abstract
Microbial biofilms develop when bacteria adhere to a substratum and grow inside a secreted extracellular matrix. They can be defined as “matrix-embedded microbial populations adherent to each other and/or to surfaces of interfaces”.31 This is the growth mode for most bacteria. Biofilms are important in human health and disease; for example, the body’s normal flora resists pathogen invasion but can itself turn pathogenic. Biofilm infections are a major problem, especially of prosthetic devices, as 1 to 3% of all orthopedic implant patients experience severe infection following surgery as the probable result of biofilm formation.2 Biofilm formation within a tube can increase frictional resistance over 200%.23 Antibacterial agents, antibiotics, phagocytic white blood cells, and other biocides are much less effective against the bacteria within a biofilm than against planktonic bacteria.52
