Microbiome of Hadza Hunter, the premature infant gut, neonatal sepsis, skin and respiratory microbiome.

Microbiome general

BacterioFiles 178 – Hadza Hunters Have Heterogeneous Helpers (14 min) – Jesse Noar – BacterioFiles

“This episode: Modern hunter-gatherers have very different gut microbes from people from agricultural societies! “

“What is the FDA Going to Think?” – Negotiating Values through Reflective and Strategic Category Work in Microbiome Science – Katherine W. Darling – Science, Technology & Human Values

“Here, we describe how values are conceptualized and negotiated within microbiome research.”

Pregnancy and Birth microbiome

Patterned progression of bacterial populations in the premature infant gut – Patricio S. La Rosa – PNAS USA

“We demonstrate via 16S rRNA gene pyrosequencing of 922 specimens from 58 subjects that the gut microbiota of premature infants residing in a tightly controlled microbial environment progresses through a choreographed succession of bacterial classes“

Development of a multiplex real-time PCR assay for the rapid diagnosis of neonatal late onset sepsis – Marre van den Brand – Journal of Microbiological Methods

“we developed a real-time multiplex PCR assay tailored to LOS diagnosis which is easy-to-use, is applicable on small blood volumes and provides species-specific results within 4 h.”

Respiratory microbiome

Uncovering the hidden villain within the human respiratory microbiome – Chun Kiat Lee, Stephen James Bent – Diagnosis

“The review herein presents the current status of human airway microbiome research and highlights potential gaps which can be translated into research possibilities for future work on respiratory tract infection diagnosis”

Skin microbiome

The skin microbiome: potential for novel diagnostic and therapeutic approaches to cutaneous disease – Elizabeth A. Grice – Skin and Allergy News

“It is increasingly apparent that this collective set of microorganisms and their genetic material, the “microbiome”, contributes genetic diversity, modulates disease, influences metabolic processes, and is essential for immunity.”

Animal models of human microbiome

Citrobacter rodentium: infection, inflammation and the microbiota – James W. Collins – Nature Reviews Microbiology

“In this Review, we discuss recent studies in which C. rodentium has been used to study mucosal immunology, including the deregulation of intestinal inflammatory responses during bacteria-induced colitis and the role of the intestinal microbiota in mediating resistance to colonization by enteric pathogens. “
