The upcoming discussion will update you about the differences between Pili and Fimbriae. Difference # Pili: 1. They occur only in Gram negative bacteria. 2. The number is 1-4 per cell. 3. Pili are longer and broader. 4. They help in conjugation. 5. Formation of pili is controlled by F+ or fertility factor. 6. They are tubular structures. Difference # [...]
In this article we will discuss the structure and functions of pili and fimbriae. Structure of Pili and Fimbriae: Both fimbriae and pili are like flagella as both are the appendages on bacterial cell wall. They originate from cytoplasm that protrudes outside after penetrating the peptidoglycan layer of cell wall. Fimbriae are made up of 100% protein called fimbrilin or [...]
