“…A significant increase in the number of bifidobacteria (DN-173010) in faeces was observed during ingestion of fermented milk, and decreased when the ingestion stopped (Collado et al, 2006). Strains which were utilized for fermentation of milk have a good opportunity to survive because some probiotics survives better when investigated in fermented milk (Pochart et al, 1992).…”

The effectiveness of the fermented milk product for decreasing the absorption of Lead (Pb) in vivo by testing several combinations of different strains and individual strains of LAB isolated from camel milk and shubat (fermented camel milk) was determined. During 4 weeks 0.5 ppm of Pb was given to cavies in fermented milk product and water. Control group and groups treated only by fermented milk products, also, were observed. Faeces, Blood, Heart, Lungs, Liver, Kidneys, and Spleen were analyzed. The lead concentrations in faeces of Control group and lead nitrate treated group were nearly the same. The quantity of Pb in faeces of fermented milk treated groups was higher than in Control and Water Pb groups. In the different cavies' organs of Water Pb group, the higher concentration of heavy metal (ppm) was observed in spleen (1.04), heart (0.65), kidneys (0.58), and blood (0.46) to be compared to 0.82, 0.2, 0.58 and 0.31 respectively in control group. In groups treated with fermented milk without/with Pb, the lead concentration decreased in target organs. Quantity of lead in blood samples of Control group and groups treated fermented milk products without/with Pb is nearly same. Highest concentration of blood Pb was observed for Water Pb group.

“…lactis showed good survival at pH values from 2.0 to 3.0 whereas strains of B. adolescentis, B. bifidum, B. breve, and B. longum displayed poor survival. Recent studies that evaluated the acid resistance of Bifidobacterium strains isolated from adult and infant faeces showed that only 40-50% were intrinsically resistant to simulated gastric conditions and remained at levels of 10 6 cfu mL À1 after 90 min of incubation at pH 2.0 (3 g L À1 pepsin with HCl at pH 2.0 (Collado, Moreno, Cobo, Mateos, & Herna´ndez, 2006)). …”

“…In human studies, the fate of bacteria has been tracked by detecting the strains in faeces or, in a few cases, in the upper human gastrointestinal tract through the use of intubation techniques (Collado, Moreno, Cobo, Mateos, & Herna´ndez, 2006;Pochart et al, 1992). The ability of a probiotic strain to survive gastrointestinal conditions also depends on the probiotic carrier and is usually enhanced when administered in fermented milks.…”

“…Some of the foregoing reported taxonomic and phylogenetic challenges are attributed to incorrect sequence naming and/or mislabeling, an issue that may require, as shown in this study, further investigation involving a multigenic approach. In support of the need of the foregoing suggestion, different authors (Marteau et al, 2002;Van der Meulen et al, 2004;Collado et al, 2006;Mayer et al, 2007;Tabbers et al, 2009) found more variation in labelling and/or nomenclature of the same strains. However, over the four months period of product sampling in this study, the identity of isolates remained the same.…”

“…animalis subsp. lactis may be the most used Bifidobacterium strain in marketed probiotic dairy products (Su et al, 2005;Collado et al, 2006;Barrangou et al, 2009), perhaps due to technological reasons. Bifidobacterium lactis for example tolerates oxygen better than Bf.…”

The 16S rRNA gene sequence analysis of Bifidobacterium species reveals high interspecies sequence similarity in the range of 87.7-99.5%. This study illustrated the extent of superiority of a multigenic approach, involving protein-coding genes, in comparison to the 16S rRNA gene, to precisely delineate presumptive Bifidobacterium isolates obtained from probiotic milk beverages, culture collections and pharmaceutical probiotic preparations. Oligonucleotide pairs PurF-rev/PurF-uni; RpoCuni/RpoC-rev; DnaB-uni/DnaB-rev; DnaG-uni/DnaG-rev; and ClpC-uni/ClpC-rev amplified housekeeping genes while 27F/ 1492R amplified the 16S rRNA gene of the presumptive bifidobacteria in a polymerase chain reaction. Sequences of 16S rRNA gene and some protein-coding genes effectively identified the isolates. Phylogenetic analysis together with concatenation showed that clpC, purF and dnaG genes had over 8-fold better discriminatory power than the 16S rRNA gene in discriminating between Bifidobacterium isolates. However, phylogenetic analysis involving dnaB and rpoC gene sequences or their concatenated trees showed discrepancies in clustering isolates with designated type strains.
