Illustration of a rod-shaped bacterium covered in hair-like pili

Transmission electron microscopy (TEM) image of Escherichia coli showing type 1 fimbriae extending from the bacterial surface, with the FimH tip adhesin visible at higher magnification.

Illustration of bacteria forming a biofilm on a surface

Confocal fluorescence microscopy of a Staphylococcus aureus biofilm stained with SYTO9 (live cells, green) and propidium iodide (dead cells, red), showing three-dimensional tower and mushroom structures.

Illustration of a bacterial adhesin binding a host cell receptor like a lock and key

Crystal structure visualization of the FimH lectin domain bound to a mannoside ligand (PDB 4X5P), showing the binding pocket residues Asp140, Asn135, and Tyr48 that form the mannose recognition site.

Illustration of a cluster of round staphylococcal bacteria

Scanning electron microscopy image of bladder epithelial cells (urothelium) colonized by uropathogenic E. coli, demonstrating intimate attachment at the bacterial-host cell interface mediated by FimH adhesin.

Illustration of a pilus being assembled through the bacterial outer membrane

Glycan microarray binding assay results showing differential binding of Streptococcus pneumoniae BgaA adhesin to sialylated glycan structures, with heat map visualization of binding intensity across 600+ glycan targets.

Illustration of a microscope field showing bacteria attached to cells

Chaperone-usher pilus assembly pathway schematic showing pilin export through Sec translocon, chaperone (FimC) binding in the periplasm, and ordered delivery to the usher (FimD) outer membrane pore.

Illustration of a rod-shaped bacterium covered in hair-like pili

Western blot and ELISA data comparing MSCRAMM surface expression in clinical S. aureus isolates from bloodstream infections versus nasal colonization samples, showing virulence-associated adhesin upregulation.

Illustration of bacteria forming a biofilm on a surface

Atomic force microscopy (AFM) force spectroscopy measurement of single FimH-mannose unbinding forces under shear flow conditions, demonstrating the catch-bond behavior that strengthens binding under flow stress.
