The food passes from the cilia-lined oral groove into a narrower structure known as the buccal ...
However, unlike E. coli Hfr conjugation, mycobacterial conjugation is chromosome rather than plasmid based. [7] [8] Furthermore, in contrast to E. coli Hfr conjugation, in M. smegmatis all regions of the chromosome are transferred with comparable efficiencies. The lengths of the donor segments vary widely, but have an average length of 44.2kb.
