Journal ArticleDOI
Encapsulation of bifidobacteria in whey protein-based microcapsules and survival in simulated gastrointestinal conditions and in yoghurt
Arnaud Picot,Christophe Lacroix +1 more
TL;DR: Immobilization of probiotic cultures in whey protein-based microcapsules can increase cell survival when subjected to extreme conditions, making this approach potentially useful for delivery of viable bacteria to the gastrointestinal tract of humans via dairy fermented products.
Journal ArticleDOI
Iron fortification adversely affects the gut microbiome, increases pathogen abundance and induces intestinal inflammation in Kenyan infants
Tanja Jaeggi,Guus A. M. Kortman,Diego Moretti,Christophe Chassard,Penny Holding,Alexandra Dostal,Jos Boekhorst,Harro M. Timmerman,Dorine W. Swinkels,Harold Tjalsma,Jane Njenga,AM Mwangi,Jane Kvalsvig,Christophe Lacroix,Michael B. Zimmermann +14 more
TL;DR: In this article, the effect of high and low dose in-home iron fortification on the infant gut microbiome and intestinal inflammation was determined by double-blind randomised controlled trials in 6-month-old Kenyan infants.
Journal ArticleDOI
The effects of iron fortification on the gut microbiota in African children: a randomized controlled trial in Côte d'Ivoire
Michael B. Zimmermann,Christophe Chassard,Fabian Rohner,Eliézer K. N’Goran,Charlemagne Nindjin,Alexandra Dostal,Jürg Utzinger,Hala Ghattas,Christophe Lacroix,Richard F. Hurrell +9 more
TL;DR: Anemic African children carry an unfavorable ratio of fecal enterobacteria to bifidobacteria and lactobacilli, which is increased by iron fortification, and this profile is associated with increased gut inflammation.
Journal ArticleDOI
Vertical mother-neonate transfer of maternal gut bacteria via breastfeeding
TL;DR: It is shown that (viable) obligate gut-associated anaerobes may be vertically transferred from mother to neonate via breastfeeding, which supports the recently suggested hypothesis of a novel way of mother-neonate communication, in which maternal gut bacteria reach breast milk via an entero-mammary pathway to influence neonatal gut colonization and maturation of the immune system.
Journal ArticleDOI
Assessment of bacterial diversity in breast milk using culture-dependent and culture-independent approaches.
TL;DR: It is suggested that breast milk may be a major source of bacterial diversity to the neonatal gut, including gut-associated obligate anaerobes, and may thus significantly influence gut colonisation and maturation of the immune system.
