CC   -!- FUNCTION: Fimbriae (also called pili), polar filaments radiating from
CC       the surface of the bacterium to a length of 0.5-1.5 micrometers and
CC       numbering 100-300 per cell, enable bacteria to colonize the epithelium
CC       of specific host organs.
CC   -!- SUBCELLULAR LOCATION: Fimbrium.
