Genomic diversity of Bifidobacterium pseudocatenulatum group

ABSTRACT: Bifidobacteria have been described as a key component of the human gut microbiota, and recently significant efforts have been made to investigate their genome contents and assess the genetic variability at inter- and intra-species level. In the current work we investigated genome diversity among representatives of bifidobacterial species, i.e., Bifidobacterium pseudocatenulatum. These analyses were performed with comparative genomic hybridization (CGH) experiments and they revealed the existence of a strictly conserved set of 685 gene families. Furthermore, CGH analyses showed that genetic regions of diversity included mobile elements and putative genomic life-style adaptation islands, such as loci that encode pili and capsular polysaccharides, and genes involved in carbohydrate metabolism
