Embodiment Construction

[0042] Experimental part

[0043] 1. Screening of Bifidobacteria

[0044] 46 strains of the genus Bifidobacterium were studied; they were commonly isolated from infant feces and belonged to 5 different species (B. bifidum, B. breve, B. longum subspecies (B. longum subsp. infantis), Bifidobacterium longum subsp. longum (B. longum subsp. longum), Bifidobacterium adolescentis (B. adolescentis) and Bifidobacterium pseudocatenulatum (B. pseudocatenulatum)). The microorganisms considered are the part present in the BUSCoB collection of DiSTA (Bologna University Scardovi Collection of Bifidobacteria, University of Bologna, Italy).

[0045] 2. Screening of target pathogenic microorganisms

[0046] Various strains of E. coli were considered: 1 E. coli strain (ATCC 11105) from a collection, 1 E. coli strain (strain M85) isolated from feces of a urinary tract infection (which had been shown in previous studies to be good target microorganism), and two strains of E. coli (strains GC6a ...

Abstract

The present invention relates to a selection of probiotic strains belonging to the genus Bifidobacterium and to a symbiotic composition containing the same, intended for feeding infants.

Description

technical field [0001] The present invention relates to the screening of a probiotic strain belonging to the genus Bifidobacterium and a symbiotic composition comprising the same for baby food. Background technique [0002] Infants fed artificial food compared with breast-fed infants showed considerable differences in the composition of the gut microbiota: this was observed in particular in order to eliminate other potentially pathogenic microorganisms such as Escherichia coli and Clostridium In the case of the genus Clostridium spp, the concentration of bifidobacteria was reduced. Microbial colonies belonging to the genus Bifidobacterium arise in breastfed infants during the first 4 days of life, and Bifidobacteria quickly become the ubiquitous microbiota. Under formula feeding, on the other hand, a more diverse flora developed consisting of coliforms, bacteroides, clostridia and streptococci. It is for these reasons that formula-fed infants are at higher risk of developi...
