Babies wage biological warfare on adults.

Infants can be colonized by toxin producing strains of Clostridium difficile but rarely develop disease. Infants and children could play a source in the spread of C. difficile disease to adults. http://jcm.asm.org/content/early/2013/10/24/JCM.01701-13.abstract http://www.asm.org/images/Communications/tips/2013/1113cdifficile.pdf Toxin-producing Clostridium difficile strains as long-term gut colonizers of healthy infants Clostridium difficile is a colonizer of the human gut, and toxin-producing…

Breast Milk Also Provides Good Gut Bacteria

Mother’s milk is the source of an infant’s gut bacteria. Given the role of good bacteria in the development of immunity and digestive health, it appears that ‘breast’ really is best. http://onlinelibrary.wiley.com/doi/10.1111/1462-2920.12238/abstract Vertical mother–neonate transfer of maternal gut bacteria via breastfeeding Babies Breast milk has recently been recognized as source of commensal and potential probiotic bacteria.…

Gut Microbial Community Linked to Malnutrition

By following Malawian twins for their first 3 years of life, the researchers find differences in the gut microbiome of well-nourished and malnourished siblings. As infants age there is a progressive change in their gut microbiomes but the microbiome in children with  kwashiorkor doesn’t seem to progress even under therapeutic nutritional intervention. Furthermore, a fecal transplant into germ-free…

Diet and Changes in Gut Microbial Enterotypes

High fat diet favours Bacteroides enterotype, while a low protein/high complex carbohydrate diet favours Prevotella enterotype. Science. 2011 October 7; 334(6052): 105–108. Linking Long-Term Dietary Patterns with Gut Microbial Enterotypes Diet strongly affects human health, partly by modulating gut microbiome composition. We used diet inventories and 16S rDNA sequencing to characterize fecal samples from 98 individuals.…
