Figure 7

Shewanella were stationary-cultured in the presence of VCBP-C. Immunofluorescent staining detected VCBP-C bound to the bacteria of the biofilms using anti-VCBP-C (Alexa Fluor 594, red). (a) Control stain (no addition of VCBP-C) using primary and secondary antibodies, (b) VCBP-C-positive biofilm. SIgA influences biofilm formation in a non-pathogenic E. coli strain. (c) Control stain (no addition of SIgA) using fluorescently tagged anti-IgA antibodies and (d) SIgA-positive biofilm. Scale bars, 20 μm.
