Variability of H2, H3, N2, and N3 sequences from the Bifidobacterium strains for which entire genome sequences have been published. Comparisons with B. longum NCC2705 were performed with MultAlin by Florence Corpet (6). The overall percentage of identity to B. longum NCC2705 is shown in the last column. Percent identity for a specific fragment: ▪, >90%; , > 80%; , < 80%. , insertion into sequence; , deletion from sequence. Bli 15697, B. longum subsp. infantis ATCC 15697; Bal AD011, B. animalis subsp. lactis AD011.
