[Conjugation in bacilli].

The review considers experimental data on the conjugal transfer of plasmids in the Bacillus cereus and Bacillus subtilis groups (the transfer of large self-transmissible plasmids and the mobilization of small plasmids). Conjugation in bacilli is compared with conjugation in E. coli dependent on the F factor. Conjugation of bacilli in their natural habitats is also discussed.
