Project description:Whole genome DNA microarray designed for the probiotic L. johnsonii strain NCC533 was used for comparative genomic hybridization (CGH) of L. johnsonii ATCC 33200T, L. johnsonii BL261, L. gasseri ATCC 33323T and L. iatae BL263 (CECT 7394T). In these experiments, the fluorescence ratio distributions obtained with L. iatae and L. gasseri showed characteristic inter-species profiles. The percentage of conserved L. johnsonii NCC533 genes was about 83% in the L. johnsonii strains comparisons and decreased to 51% and 47% for L. iatae and L. gasseri, respectively. These results confirmed the separate status of L. iatae from L. johnsonii at the level of species, and also that it is closer to L. johnsonii than L. gasseri.

Comparative genome hybridization for Lactobacillus casei

Project description:Lactobacillus casei is remarkably adaptive to diverse habitats. To understand the evolution and adaptation of Lb. casei strains isolated from different environments, the gene content of 22 Lb. casei strains isolated from various habitats (cheeses, n=8; plant materials, n=8; and human sources, n=6) were examined by comparative genome hybridization with an Lb. casei ATCC 334-based microarray. Comparative genome hybridization was performed against an Affymetrix custom microarray designed to include 2,661 (97%) chromosomal and 17 (85%) plasmid CDSs predicted to occur in Lb. casei ATCC 334, as well as all predicted CDSs in the draft Lb. helveticus CNRZ 32 genome. CDSs that were not included in the microarray design were all transposase-encoding genes.
