Microorganisms growing on surfaces can form biofilms under certain conditions. In this issue of Cell, Ojha et al. (2005) investigate biofilm formation in mycobacteria. They identify new cell-wall components that are required for the formation of architecturally complex mature biofilms in these bacteria and the surprising involvement of a chaperone protein in this process. ©2005 Elsevier Inc.
