Figure 4From: Comparative genomics reveals distinct host-interacting traits of three major human-associated propionibacteriaAtomic force microscopy of P. avidum ATCC25577. A) Amplitude image of the overall morphology of the cells. Extracellular structures are clearly visible, extending out from the cell surface. B) and C) Height images showing extracellular structures collapsed onto the glass coverslip. The fiber-like structures measure 1-3 nm in diameter. X-Y scalebar = 1 μm, z scale is indicated by color.Back to article page
