Question

Explain bacterial Fimbriae structure

Answer 1

The number of fimbriae is around 1,000. However, a similar structure has also been observed only in Corynebacterium renale, a Gram-positive bacterium. Pili differ from flagella in being shorter and thinner, straight and less ligid. But they are in large number. They occur either at the poles of bacterial cell or evenly distributed over the entric surface of the cell. The pili are 0.2-20 µm long with a diameter of about 250 Å.
