This note represents a grouping of identical Lactococcus lactis sequences from 
various subspecies and strains.  These sequences are represented as Group 1.
The other Lactococcus lactis sequences are in Groups 2, 3, and 4.  In all four groups, 
there are 15 sequences total.

The full names and GenBank accession numbers of Lactococcus lactis sequences classified in 
Group 1 are as follows:

Organism name                                                      GenBank AC#
Lactococcus lactis sbsp. lactis strain NCDO2118                     AF375552
Lactococcus lactis sbbp. lactis strain IL638                        AF375557
Lactococcus lactis sbsp. lactis strain CNRZ337                      AF375561
Lactococcus lactis sbsp. lactis biovar diacetylacis strain IL890    AF375558
Lactococcus lactis sbsp. lactis strain IL2962                       AF375555
