Human microbiome digest, June 4, 2014

Today’s featured paper describes the gut microbiota of malnourished Bangladeshi children and was published in Nature. But we also cover oral cancer and babies’ dummies (pacifiers).

Gut microbiome

“ In the current study, bacterial species whose proportional representation define a healthy gut microbiota as it assembles during the first two postnatal years were identified by applying a machine-learning-based approach to 16S ribosomal RNA data sets generated from monthly faecal samples obtained from birth onwards in a cohort of children living in an urban slum of Dhaka, Bangladesh, who exhibited consistently healthy growth. “

“Undernourished children fall behind not only on growth, but also on maturation of their intestinal bacterial communities, according to a study comparing acutely malnourished and healthy Bangladeshi children.”

“The gut bacterial communities of severely malnourished children appear to be less developed than those of healthy children, a study on Bangladeshi infants and toddlers finds.”

Oral microbiome

“To investigate changes in the microbiome associated with oral cancers, we profiled cancers and anatomically matched contralateral normal tissue from the same patient by sequencing 16S rDNA hypervariable region amplicons. “

“In this post I will report on my most recent self-experiment. Some of this experiment was intentional, and some of it was non-intentional – with regards to my oral hygiene at least.”

Pregnancy and birth

“Children whose mother’s sucked their dummies to clean them were a third less likely to develop asthma and eczema, Prof Graham Rook, told the Cheltenham Science Festival. “If the parents pick up the dummy right away and sterilises it or replace it with a new clean one, that child has a considerably greater chance of having eczema and asthma,” he said.”

“While short IPI is a known risk factor for preterm birth, our data show that inadequate birth spacing is associated with decreased gestational age for all births.”
