Abstract: Biofilms Up Close Many bacterial infections involve biofilm formation. Cells within a biofilm are significantly more resistant to immune clearance and antibiotics compared to unattached, planktonic cells. Berk et al. (p. 236 ) applied superresolution optical methods to image living bacteria with nanometer-scale precision as they form a biofilm. Vibrio cholerae biofilms were observed to have three distinct levels of spatial organization: cells, clusters of cells, and collections of clusters. Each cell cluster was wrapped in a flexible, elastic e...
