Immunogold electron microscopy demonstrating expression of type 3 fimbriae in E. coli ECOR15 and C. koseri M546. Expression of type 3 fimbriae at the cell surface was demonstrated by abundant labelling with anti-type 3 fimbriae-gold particles. In contrast, the deletion mutants, E. coli ECOR15mrk and C. koseri M546mrk were virtually devoid of gold labelling. Scale bar represents 1 μm.
