Today’s digest is a long one! There is high diversity of studies, with a high abundance of gut microbiome studies, a few publications on fecal transplant, and some very interesting early life/pregnancy/mother-infant science.  A normal serving of animal studies, of course a nice colony of environmental microbial studies, and a study reporting the presence of bacteria in Alzheimer’s post-mortem brains.

An early life focus today: Interesting papers on the effects of a pre-term cesarian birth on the gut microbiome and the impact of the infant gut microbiome on food allergies. Also highlighted, the relationship between the gut microbiome and social stress vulnerability in mice, the role of the gut microbiome in mosquito development, and evidence of a permanent transfer of prokaryotic virus sequences to the mammalian brain.
