Importance of bifidobacteria as part of the infant intestinal microbiota has been highlighted. Their acquisition is influenced by the mode of birth and the feed regime afterwards, with a special role of the maternal microbiota. The presence of the same shared bifidobacterial strains between breast milk and infant faeces in 14 mother-infant pairs was assessed by means of pulsed-field gel electrophoresis (PFGE) genotyping. Four shared strains of Bifidobacterium breve (2), Bifidobacterium longum subsp. infantis and B. longum subsp. longum were found in breast milk-infant faeces pairs. Two years later, a second survey yielded four shared strains of the species Bifidobacterium adolescentis, Bifidobacterium bifidum, B. longum subsp. longum and Bifidobacterium pseudocatenulatum. Moreover, a B. bifidum strain was found to be shared by the infant faeces of the first study and the mother faeces tested two years later, pointing out a long term persistence. Some of the selected bifidobacterial strains showed probiotic potential due to their survival to gastrointestinal conditions and their ability to form biofilms.

Copyright © 2020 American Society for Microbiology. Bifidobacterial species are common inhabitants of the gut of human infants during the period when milk is a major component of the diet. Bifidobacterium breve, Bifidobacterium bifidum, Bifidobacterium longum subspecies longum, and B. longum subspecies infantis have been detected frequently in infant feces, but B. longum subsp. infantis may be disadvantaged numerically in the gut of infants in westernized countries. This may be due to the different durations of breast milk feeding in different countries. Supplementation of the infant diet or replacement of breast milk using formula feeds is common in Western countries. Formula milks often contain galacto- and/or fructo-oligosaccharides (GOS and FOS, respectively) as additives to augment the concentration of oligosaccharides in ruminant milks, but the ability of B. longum subsp. infantis to utilize these potential growth substrates when they are in competition with other bifidobacterial species is unknown. We compared the growth and oligosaccharide utilization of GOS and FOS by bifidobacterial species in pure culture and coculture. Short-chain GOS and FOS (degrees of polymerization [DP] 2 and 3) were favored growth substrates for strains of B. bifidum and B. longum subsp. longum, whereas both B. breve and B. longum subsp. infantis had the ability to utilize both short- and longer-chain GOS and FOS (DP 2 to 6). B. breve was nevertheless numerically dominant over B. longum subsp. infantis in cocultures. This was probably related to the slower use of GOS of DP 3 by B. longum subsp. infantis, indicating that the kinetics of substrate utilization is an important ecological factor in the assemblage of gut communities.IMPORTANCE The kinds of bacteria that form the collection of microbes (the microbiota) in the gut of human infants may influence health and well-being. Knowledge of how the composition of the infant diet influences the assemblage of the bacterial collection is therefore important because dietary interventions may offer opportunities to alter the microbiota with the aim of improving health. Bifidobacterium longum subspecies infantis is a well-known bacterial species, but under modern child-rearing conditions it may be disadvantaged in the gut. Modern formula milks often contain particular oligosaccharide additives that are generally considered to support bifidobacterial growth. However, studies of the ability of various bifidobacterial species to grow together in the presence of these oligosaccharides have not been conducted. These kinds of studies are essential for developing concepts of microbial ecology related to the influence of human nutrition on the development of the gut microbiota.

Breast milk can be a source of potential probiotic bacteria, but the technological capacity of isolates obtained from this source is not always guaranteed. We aimed at isolating lactobacilli from breast milk samples collected in Argentina, focusing on isolates with functional and technological potential as probiotics. Fourteen Lactobacillus and one Bifidobacterium isolates were obtained from 164 samples donated by 104 mothers. The isolates preliminarily identified by MALDI-TOF, and then the identity was confirmed by partial 16S rRNA gene sequencing. Hydrophobicity was determined (hexadecane and xylene partition). The strains were also co-cultured with murine RAW 264.7 macrophages for screening the capacity to induce the anti-inflammatory cytokine interleukin (IL)-10. Hydrophobicity ranged from 7.4 and 95.9%. The strains Lactobacillus gasseri (70a and 70c) and Lactobacillus plantarum (73a and 73b) were the strains with a higher capacity to induce IL-10 production by macrophages. The technological application was evaluated by freezing dried in 10% lactose or 10% polydextrose. The survival was assessed after accelerated (37 °C, 4 weeks) or long-term (5 and 25 °C, 12 months) storage. Except for Lactobacillus gallinarum 94d, strains lost less than 1 Log10 order cfu/g after long-term (12 months) storage at 5 °C in lactose and polydextrose as protectants. A low correlation between survival to accelerated and long-term storage tests was observed. L. gasseri (70a and 70c) and L. plantarum (73a and 73b) deserve further studies as potential probiotics due to their capacity to induce IL-10 from murine macrophages and their hydrophobicity. In special, L. plantarum 73a was able to confer enhanced protection against Salmonella infection by promoting the immunity of the small intestine.

Methodological Aspects

Pregnancy and lactation are times of additional demand for Ca. Ca is transferred across the placenta for fetal skeletal mineralisation, and supplied to the mammary gland for secretion into breast milk. In theory, these additional maternal requirements could be met through mobilisation of Ca from the skeleton, increased intestinal Ca absorption efficiency, enhanced renal Ca retention or greater dietary Ca intake. The extent to which any or all of these apply, the underpinning biological mechanisms and the possible consequences for maternal and infant bone health in the short and long term are the focus of the present review. The complexities in the methodological aspects of interpreting the literature in this area are highlighted and the inter-individual variation in the response to pregnancy and lactation is reviewed. In summary, human pregnancy and lactation are associated with changes in Ca and bone metabolism that support the transfer of Ca between mother and child. The changes generally appear to be independent of maternal Ca supply in populations where Ca intakes are close to current recommendations. Evidence suggests that the processes are physiological in humans and that they provide sufficient Ca for fetal growth and breast-milk production, without relying on an increase in dietary Ca intake or compromising long-term maternal bone health. Further research is needed to determine the limitations of the maternal response to the Ca demands of pregnancy and lactation, especially among mothers with marginal and low dietary Ca intake, and to define vitamin D adequacy for reproductive women.

ABSTRACTLactoferrin is an iron-binding glycoprotein found in the milk of most mammals for which various biological functions have been reported, such as antimicrobial activity and bifidogenic activity. In this study, we compared the bifidogenic activity of bovine lactoferrin (bLF) and pepsin hydrolysate of bLF (bLFH), isolated bifidogenic peptide from bLFH, and investigated the bifidogenic spectra of bLF, bLFH, and its active peptide against 42 bifidobacterial strains comprising nine species. AgainstBifidobacterium breveATCC 15700T, minimal effective concentrations of bLF and bLFH were 300 and 10 μg/ml. AgainstBifidobacterium longumsubsp.infantisATCC 15697T, the minimal effective concentration of bLFH was 30 μg/ml, and bLF did not show bifidogenic activity within 300 μg/ml. As an active peptide, a heterodimer of A1-W16and L43-A48linked by a disulfide bond was isolated. Previously, this peptide was identified as having antibacterial activity. An amino acid mixture with the same composition as this peptide showed no bifidogenic activity. The strains of each species whose growth was highly promoted (>150%) by this peptide at 3.75 μM were as follows:B. breve(7 out of 7 strains [7/7]),B. longumsubsp.infantis(5/5),Bifidobacterium bifidum(2/5),B. longumsubsp.longum(1/3),Bifidobacterium adolescentis(3/6),Bifidobacterium catenulatum(1/4),Bifidobacterium pseudocatenulatum(0/4),Bifidobacterium dentium(0/5), andBifidobacterium angulatum(0/3). Growth of none of the strains was highly promoted by bLF at 3.75 μM. We demonstrated that bLFH showed stronger bifidogenic activity than natural bLF, especially against infant-representative species,B. breveandB. longumsubsp.infantis; furthermore, we isolated its active peptide. This is the first report about a bifidogenic peptide derived from bLF.

Одним из приоритетных направлений пищевых технологий является создание продуктов, обладающих лечебно-профилактическим и функциональным действием, в частности кисломолочных симбиотических продуктов, сочетающих в себе сложные компоненты направленного действия – пробиотики и пребиотики. Цель работы – исследование взаимодействия штаммов различных видов бифидобактерий для получения на их основе консорциума с новыми биотехнологическими свойствами и создание синбиотического кисломолочного продукта с высоким титром бифидобактерий. Объектами исследований были выбраны штаммы Bifidobacterium bifidum 791, Bifidobacterium longum 379 М, Bifidobacterium adolescentis МС-42. При оценке качества в работе применяли общепринятые методы исследований. Установлено, что оптимальным соотношением штаммов B. bifidum 791, B. longum 379 М, B. аdolescentis МС-42 в составе комбинированной закваски является 1:1:2. Диско-диффузионным методом проведен анализ устойчивости консорциума к 23 антибиотикам разных поколений и спектров действий. Наибольшая устойчивость отмечена к бета-лактамным антибиотикам, бактерицидная активность которых обусловлена ингибированием синтеза клеточной стенки микроорганизмов. Также изучено влияние различных концентраций пребиотиков полисахаридной природы (пектина и инулина) на изменение количества жизнеспособных клеток бифидобактерий. Показано, что синбиотический кисломолочный продукт на основе подобранного консорциума бифидобактерий с внесением 2,5 % пектина может быть рекомендован для профилактики и коррекции нарушений дисбаланса кишечной микрофлоры, а также поддержания неспецифической резистентности организма.

ABSTRACT Although the health-promoting roles of bifidobacteria are widely accepted, the diversity of bifidobacteria among the human intestinal microbiota is still poorly understood. We performed a census of bifidobacterial populations from human intestinal mucosal and fecal samples by plating them on selective medium, coupled with molecular analysis of selected rRNA gene sequences (16S rRNA gene and internally transcribed spacer [ITS] 16S-23S spacer sequences) of isolated colonies. A total of 900 isolates were collected, of which 704 were shown to belong to bifidobacteria. Analyses showed that the culturable bifidobacterial population from intestinal and fecal samples include six main phylogenetic taxa, i.e., Bifidobacterium longum, Bifidobacterium pseudocatenulatum, Bifidobacterium adolescentis, Bifidobacterium pseudolongum, Bifidobacterium breve, and Bifidobacterium bifidum, and two species mostly detected in fecal samples, i.e., Bifidobacterium dentium and Bifidobacterium animalis subp. lactis. Analysis of bifidobacterial distribution based on age of the subject revealed that certain identified bifidobacterial species were exclusively present in the adult human gut microbiota whereas others were found to be widely distributed. We encountered significant intersubject variability and composition differences between fecal and mucosa-adherent bifidobacterial communities. In contrast, a modest diversification of bifidobacterial populations was noticed between different intestinal regions within the same individual (intrasubject variability). Notably, a small number of bifidobacterial isolates were shown to display a wide ecological distribution, thus suggesting that they possess a broad colonization capacity.

The genus Bifidobacterium comprises various bacterial species, and the complement of species within the human intestinal tract differs from individual to individual. The balance of these bifidobacterial species remains poorly understood, although it is known that the abundance of bifidobacteria increases following the ingestion of prebiotics. We previously conducted a randomised, placebo-controlled, double-blind, crossover study of 2 g/day lactulose ingestion for 2 weeks in 60 Japanese women. To study the effect of lactulose ingestion on each bifidobacterial species, here, we measured the abundance of each of the principal bifidobacterial species. After lactulose ingestion, the log cell counts of the Bifidobacterium adolescentis group (8.97±0.08 vs 9.39±0.08, P=0.0019), Bifidobacterium catenulatum group (9.45±0.10 vs 9.65±0.10, P=0.0032) and Bifidobacterium longum group (9.01±0.07 vs 9.29±0.07, P=0.0012) were significantly higher than in the placebo ingestion control group. However, the log cell counts were similar for Bifidobacterium breve (8.12±0.12 vs 8.33±0.12, P=0.20), Bifidobacterium bifidum (9.08±0.12 vs 9.42±0.14, P=0.095) and Bifidobacterium animalis subspecies lactis (8.65±0.53 vs 8.46±0.46, P=0.77). Cluster analysis of the log cell count data at the bifidobacterial species level revealed three distinct clusters, but the combinations and ratios of the constituent bifidobacteria were not affected by lactulose ingestion. Furthermore, principal coordinate analysis of the intestinal microbiota in the lactulose and placebo ingestion groups using Illumina MiSeq showed no significant differences in the intestinal microbiota as a whole. These results suggest that 2 g/day lactulose ingestion for 2 weeks significantly increases the abundance of intestinal bifidobacteria, but does not affect the intestinal microbiota as a whole.

Bifidobacteria are among the first colonisers of the gastrointestinal tract of breast-fed newborns due to, among other things, their ability to metabolise oligosaccharides naturally occurring in human milk. The presence of bifidobacteria in the infant gut has been shown to promote intestinal health and homeostasis as well as to preserve a functional gut barrier, thus positively influencing host health and well-being. Among human-associated gut commensals, Bifidobacterium bifidum has been described as the only species capable of the extracellular degradation of both mucin-type glycans and HMOs, thereby giving this species a special role as a commensal gut forager of both host and diet-derived glycans. In the present study, we assess the possible beneficial properties and probiotic potential of B. bifidum strain CNCM I-4319. In silico genome analysis and growth experiments confirmed the expected ability of this strain to consume HMOs and mucin. By employing various animal models, we were also able to assess the ability of B. bifidum CNCM I-4319 to preserve gut integrity and functionality from stress-induced and inflammatory damage, thereby enforcing its potential as an effective probiotic strain.

ABSTRACT Human milk is known to carry its own microbiota, of which the precise origin remains obscure. Breastfeeding allows mother-to-baby transmission of microorganisms as well as the transfer of many other milk components, such as human milk oligosaccharides (HMOs), which act as metabolizable substrates for particular bacteria, such as bifidobacteria, residing in infant intestinal tract. In the current study, we report the HMO composition of 249 human milk samples, in 163 of which we quantified the abundance of members of the Bifidobacterium genus using a combination of metagenomic and flow cytometric approaches. Metagenomic data allowed us to identify four clusters dominated by Bifidobacterium adolescentis and Bifidobacterium pseudolongum, Bifidobacterium crudilactis or Bifidobacterium dentium, as well as a cluster represented by a heterogeneous mix of bifidobacterial species such as Bifidobacterium breve and Bifidobacterium longum. Furthermore, in vitro growth assays on HMOs coupled with in silico glycobiome analyses allowed us to elucidate that members of the Bifidobacterium bifidum and B. breve species exhibit the greatest ability to degrade and grow on HMOs. Altogether, these findings indicate that the bifidobacterial component of the human milk microbiota is not strictly correlated with their ability to metabolize HMOs.
