Human microbiome digest, October 27, 2014

Development of gut microbiome in infants, understanding oral microbiome through high-throughput sequencing, gut bacteria in deceased alcoholics, and bacteria after stroke.

Microbiome general

The symbiont side of symbiosis: do microbes really benefit? – Justine R. Garcia and Nicole M. Gerardo – Frontiers in Microbiology

“We evaluate these hypotheses based on available evidence, which indicate reduced competition and predation are not universal benefits for symbionts. “

Pregnancy and birth microbiome

Review: Diet and the development of the human intestinal microbiome – Noah Voreades – Frontiers in Microbiology

“This review focuses primarily on diet, as it is one of the most pivotal factors in the development of the human gut microbiome from infancy to the elderly.”

Human oral microbiome

Review: Application of high-throughput sequencing in understanding human oral microbiome related with health and disease – Hui Chen and Wen Jiang – Frontiers in Microbiology

“This review describes the application of high-throughput sequencing for characterization of oral microbiota and analyzing the changes of the microbiome in the states of health or disease.”

Human gut microbiome

Cellular and molecular pathways through which commensal bacteria modulate sensitization to dietary antigens – Taylor Feehley, Cathryn R Nagler – Current Opinion in Immunology

“This review will discuss the cellular and molecular pathways activated by commensal bacteria to protect against allergic sensitization.”

Microbial Therapy in Liver Disease: Probiotics Probe the Microbiome–Gut–Liver–Brain Axis – David W. Victor 3rd, Eamonn M.M. Quigley – Gastroenterology

“It is timely, therefore, that Dhiman et al should embark on an ambitious study, reported in this issue of Gastroenterology, designed to assess the efficacy of the probiotic cocktail, VSL#3, as secondary prophylaxis in patients with OHE.”

Changes in gut bacterial populations and their translocation into liver and ascites in alcoholic liver cirrhotics – Sari Tuomisto – BMC Gastroenterology

“Relative ratios of major commensal bacterial communities (Bacteroides spp., Bifidobacterium spp., Clostridium leptum group, Enterobactericaea and Lactobacillus spp.) were determined in faecal samples from post mortem examinations performed on 42 males”

Animal models of microbiome research

Age-related changes in intestinal permeability and gut microbiota after ischemic stroke – Joshua Crapser – Journal of Neuroimmunology

“This study aimed to elucidate the role of systemic factors, such as intestinal stress, underlying the poor outcomes of aging mice after stroke.”

Spatial and temporal colonization dynamics of segmented filamentous bacteria is influenced by gender, age and experimental infection with Helicobacter hepaticus in Swiss Webster mice – Zhongming Ge – Microbes and Infection

“Hh infection in both genders did not alter SFB levels in the jejunum and ileum, but increased SFB levels in the cecum and colon of males compared to the controls”
