Microbiome digest, October 10, 2014

A quiet day in microbiome literature. Some general microbiome reviews, a phage commonly found in insect symbionts, and an unusual fecal transplant.

General microbiome

Viruses and the Microbiota – Christopher M. Robinson and Julie K. Pfeiffer – Annual Review of Virology

“This review examines the known effects and mechanisms by which microbiota influence mammalian virus infections.”

Review: The Microbiota, Chemical Symbiosis, and Human Disease – Matthew R. Redinbo – Journal of Molecular Biology

“Here, the recent literature linking the microbiota to diseases of three of the key mammalian mucosal epithelial compartments – nasal, lung and gastrointestinal (GI) tract – is reviewed with a focus on new knowledge about the taxa, species, proteins and chemistry that promote health and impact progression toward disease.”

Human gut microbiome

Alien Invasions and Gut “Island Biogeography” – Edward F. DeLong – Cell

“Now, Seedorf et al. show that microbiota from a variety of disparate habitats can successfully colonize and compete in the mammalian gut environment.”

Review: The small intestine microbiota, nutritional modulation and relevance for health – Sahar El Aidy – Current Opinion in Biotechnology (April 2015 issue!)

“This review highlights the recent advances made in the study of the human small intestine microbiota”

The Opposing Forces of the Intestinal Microbiome and the Emerging Pathobiome – Jennifer Defazio – Surgical Clinics of North America

Insect microbiome

Arsenophonus insect symbionts are commonly infected with APSE, a bacteriophage involved in protective symbiosis – Olivier Duron – FEMS Microbiology Ecology

“APSE was found in association with two-thirds of the Arsenophonus strains examined and from a variety of insect groups such as aphids, white flies, parasitoid wasps, triatomine bugs, louse flies, and bat flies.”

Microbes in the news

Beyond the call: Scientist self-administers fecal transplant in search for healthy microbiome – Helen Clark – GizMag

Dr. Raphael Kellman’s Microbiome Diet – Faith Middleton, Lori Mack, Jonathan McNicol – WNPR News

“Repair and boost the bacteria in the gut with the right food, prebiotics and probiotics, and you’ll feel better and lose weight. That’s the theory of Dr. Raphael Kellman of New York, author of The Microbiome Diet.”

The Mad Science Behind OMSI’s Greatest Exhibits – Nathan Tucker

“During my visit, the primary focus is on the shop’s next big traveling exhibition, an NSF-funded exploration of the human microbiome called The Zoo in You. “
