Contact with the surface may induce changes in the bacteria gene expression, for example the synthesis of extracellular polysaccharides is upregulated [2]. Also, within minutes microorganisms upregulate the secretion of intercellular signaling molecules; however, a strong attachment of microcolonies occurs only after a few hours [3].

      Biofilms in Medicine

      After being neglected for several decades, biofilms are gaining more and more interest in medicine. There are infections associated with biofilm formation on incorporated materials or medical devices used for treatment. Furthermore, other infections are clearly associated with biofilms, such as chronic wound infections and lung infections in cystic fibrosis. The diagnostic criteria for identifying a biofilm-associated infection are a localized chronic or foreign infection, or a medical history of predisposing factors for biofilm formation, such as cystic fibrosis, a recurrent infection, and antibiotic failure, among others [3].
