title: [Methods for detection of biofilm formation in routine microbiological practice].
abstract: The increasing use of catheters, artificial implants and antimicrobials as well as high numbers of immunocompromised patients are major causes for concern over biofilm infections. These infections are characterized particularly by high resistance to antimicrobials and formation of persistent foci that may complicate therapy. Therefore, detection of biofilm formation is of high relevance to the clinician and his/her approach to the treatment. Reliable and sensitive methods for detection of this pathogenicity factor in clinically important organisms, suitable for use in routine microbiological laboratories, are needed for this purpose. Currently, a wide array of techniques are available for detection of this virulence factor, such as biofilm visualization by microscopy, culture detection, detection of particular components, detection of physical and chemical differences between biofilm-positive organisms and their planktonic forms and detection of genes responsible for biofilm formation. Since each of these methods has limitations, the best results can be achieved by combining different approaches.
