Supporting parties

ESCMID Study Group for Biofilms (ESGB). Biofilms are communities of microorganisms that are attached to each other and/or a biotic or abiotic surface, are embedded in a self-produced extracellular matrix, and show markedly reduced susceptibility to antimicrobial agents. It is estimated that the majority of chronic infections and most device-related infections are biofilm-associated. However, biofilm infections are difficult to diagnose and extremely difficult to treat.

The objective of ESGB is to increase knowledge on various aspects of microbial biofilms with as ultimate goals improved diagnostic tools for biofilm infections, and better approaches to prevent and treat such infections. In order to obtain these goals, a multidisciplinary approach is necessary and one of the objectives of the ESGB to facilitate cooperation between scientist working on biofilms in different disciplines.
