FIG. 2.

Schematic presentation of V3 region relatedness. Pairwise distances were calculated from the V3 region of 16S rDNA. The dendrogram was constructed by using the neighbor-joining method included in the GeneCompar software (Applied Maths). Sequences used for this analysis were obtained either from the CNRZ collection database (Elodie Lepage, Unité de Recherches Laitières et Génétique Appliquée) or from the GenBank database. delb., delbrueckii; mes., mesenteroides.
