  2. bLetters represent blp genes; those marked with an asterisk represent genes with only a pnc name.
  3. cLetters in boldface font represent bacteriocin precursor genes; those underlined represent membrane protein genes (with a putative function in immunity).
  4. dInsertion sequences are not shown in this table.
  5. eFour pherogroups, A-D, plus a heterogeneous group, H/M, were identified among the blp cassettes. See Additional file 3 for further details.
