Class A, sequences with homology to E. coli Sakai (14) genes; class B, sequences with homology to bacteriophage sequences not found in E. coli Sakai; class C, putative mosaic sequences with homology to both E. coli Sakai and non-Sakai DNA sequences within the same contig; class D, sequences with homology to E. coli Sakai genes but lacking synteny with the E. coli Sakai chromosome; class E, sequences with homology to previously published nonbacteriophage and non-Sakai DNA sequences; class F, sequences with regions containing no homology to any annotated DNA sequences in GenBank.
