On the basis of the attached compilation reviewing the range of 
extra-chromosomal transfer among gram positive bacteria (see Tables A 
and B) we should like to propose the establishment of a comprehensive 
exchanger list for the gram positive Eubac te r i a I es , including the fol- 
lowing genera and species: 
Bac i 1 1 us tereus

For the above listed organisms the following exchange pattern has been 
demonstrated by use of natural means of genetic transfer (transduction, 
conjugation, competent cell transformation, mixed culture mechanism 
unspecified -. See Table A):
