They are small bristle like fibres which develop from the surface of bacterial cells. They are quite numerous (300-400 cell). They take part in attachment, mutual aggregation or attachment to host tissue. 


Bacteria reproduces mainly by vegetative and asexual methods of reproduction. However, they also exhibit some amount of genetic recombination.

Binary fission:

This is the universal method of multiplication in bacteria in which the cell divides into two equal parts by a transverse constriction of the cytoplasm.

Then nucleus divides amitotically and the process of binary fission is completed in 20-30 minutes.
