In recent years, the knowledge about bifidobacteria has considerably evolved thanks to recent progress in molecular biology. The analysis of the whole genome sequences of 48 taxa of bifidobacteria offers new perspectives for their classification, especially to set up limit between two species. Indeed, several species are presenting a high homology and should be reclassified. On the other hand, ...

We investigated the impact of parenteral antibiotic treatment in the early neonatal period on the evolution of bifidobacteria in the newborn. Nine babies treated with intravenous ampicillin/gentamicin in the first week of life and nine controls (no antibiotic treatment) were studied. Denaturing gradient gel electrophoresis was used to investigate the composition of Bifidobacterium in stool samp...

AIM Previously, glutamine-enriched enteral nutrition in very low birth weight infants (VLBW) decreased the incidence of atopic dermatitis at age 1 year. The aim of this study was to determine whether this effect is related to changes in intestinal bacterial species that are associated with allergy, such as bifidobacteria, clostridium histolyticum, clostridium lituseburense (Chis/lit group) and ...

Members of the genus Bifidobacterium are among the first microbes to colonize the human gastrointestinal tract and are believed to exert positive health benefits on their host. Due to their purported health-promoting properties, bifidobacteria have been incorporated into many functional foods as active ingredients. Bifidobacteria naturally occur in a range of ecological niches that are either d...

conclusions these human-derived lab and bifidobacteria exhibited different mechanisms involved in pathogenic inhibition. therefore a combination of these probiotic strains could be a great promise and possibility for the development of probiotic products to effectively prevent and control food-borne infection in humans. background food-borne pathogens are among the most significant problems in ...

Lactobacilli and bifidobacteria are important members of the gastrointestinal microflora of man and animals. There is a substantial and growing body of evidence that these microbes provide benefits to the host in which they reside. Understanding the roles of these two groups of bacteria in the intestine continues to be a significant challenge. To this end, genetic characterisation and manipulat...

Bifidobacteria were originally isolated by Tissier at the beginning of the last century from infant stool samples and until now 57 (sub)species have been included in this bacterial genus (Turroni et al., 2011; Milani et al., 2014). Bifidobacterial biology has captured increasing attention in the last 15 years due to widespread interest in using bifidobacteria as health promoting microorganisms,...

Bifidobacteria are high G+C Gram positive bacteria belonging to the phylum Actinobacteria. In recent years bifidobacteria have attracted a lot of attention because of their perceived positive contribution to the functionality of the human gastro intestinal tract. For this reason, scientific research on these bacteria has been rapidly expanding, in particular in areas such as genomics, molecular...

Bifidobacteria are one of the predominant bacterial groups of the human intestinal microbiota and have important functional properties making them interesting for the food and dairy industries. Numerous in vitro and preclinical studies have shown beneficial effects of particular bifidobacterial strains or strain combinations on various health parameters of their hosts. This indicates the potent...

The paper deals with cryopreservation of bifidobacteria and bacteriophages. Effect of high rates of cooling on survival ability and physiological activity of bifidobacteria is evaluated. The possibility to use rapid freezing for cryopreservation of stock Pseudomonas phage cultures is examined. The study indicates that rapid cooling kinetics appeared to lead to minimal losses in viability and ac...
