| Sumario: | Biofilm formation: Architecture and antibiotics Studying how the architecture of bacterial biofilms can change on exposure to antibiotics could help tackle persistent clinical infections. Enterococcus faecalis is one of the most prevalent bacteria involved in healthcare situations. Its resistance to antibiotics is elevated by the formation of biofilms. Gary Dunny and colleagues at the University of Minnesota, USA studied genetic factors related to the response of E. faecalis biofilms to antibiotics. They identified mutations that caused the bacterial cells to produce structurally altered biofilms and found that similar structural alterations were induced in biofilms made by normal cells in the presence of antibiotics. The altered architecture can make the biofilms less stable and therefore more easily disrupted by treatments. Learning more about the mechanisms underlying these structural changes in biofilms might lead to new options in treating antibiotic resistant infections. |
