Role of gut microbiota diversity in protection from asthma and allergy development

23 Dec 2016

by Andreu Prados

A recent study led by Dr. Alex Mira (FISABIO, Spain) and Dr. Maria C. Jenmalm (Linköping University, Sweden) and researchers at IATA-CSIC (Spain) has presented an analysis of a total of 192 faecal samples from 28 healthy children and 20 children developing allergic symptoms at age seven, from when the children were 1 and 12 months of age. It has found that children who develop asthma or allergies later in life have altered immune responses to intestinal bacteria in the gut mucosal environment at an early age.

Researchers identify intestinal microbiota profile related to severity of IBS symptoms

21 Dec 2016

by Andreu Prados

A recent study, led by Prof. Magnus Simrén from the Department of Internal Medicine & Clinical Nutrition and University of Gothenburg Centre for Person-Centered Care at the University of Gothenburg in Gothenburg (Sweden), has identified a gut microbiota profile that is related to the severity of IBS symptoms.

Probiotics may help prevent chemoradiotherapy-induced diarrhoea in people with abdominal and pelvic cancer

19 Dec 2016

by Paul Enck

A recent systematic review and meta-analysis, led by Dr. C-X Pei from The First Clinical Medical College and Evidence Based Medical Centre of Lanzhou University in Lanzhou (China), has shown that probiotics may have a role in prevention of chemoradiotherapy-induced diarrhoea in people with abdominal and pelvic cancer, and are rarely associated with adverse events.

Until now, three case-control studies have assessed gut microbiota in PD: a Finnish study, an American study, and a Japanese study.

Connections revealed between diet, gut microbiome and migraines

12 Dec 2016

by Andreu Prados

A recent study, led by Rob Knight from the Department of Paediatrics at the University of California San Diego in California (USA), has found that migraine sufferers have higher levels of oral bacteria involved in processing nitrates, which could make them more sensitive to certain foods that may act as migraine triggers.

Sleep loss may impact the gut microbiota in healthy, young normal-weight individuals

9 Dec 2016

by Andreu Prados

A recent study, led by Dr. Jonathan Cedernaes from the Department of Neuroscience at Uppsala University (Sweden), has found that short-term sleep loss may induce subtle changes in the human gut microbiota.

Targeted antimicrobials in the oral microbiome

7 Dec 2016

by Melissa Agnello

Most mucosal surfaces of the human body contain an extremely complex ecosystem of microbial organisms. These resident microbes exist in a delicate balance with each other and the human host that is dictated by the specific local environmental factors of each host body site. In health, the many different species that make up the microbiota exist in homeostasis with the host immune system. A dysbiosis of the microbiota shifts the community, which may lead to disease.

New insights into how Akkermansia muciniphila improves metabolic health, leading to first human safety trial

5 Dec 2016

by Kristina Campbell

Previous studies have identified Akkermansia muciniphila as an important bacterium in metabolic health—able to prevent the development of obesity in animal models. Until now, however, its mechanisms were unclear and its effects had never been tested in humans.

Gut bacterial populations can be shaped by competing species as well as gut motility

2 Dec 2016

by Kristina Campbell

Researchers from the University of Oregon in Eugene (USA) recently published a study that used zebrafish as a vertebrate model for investigating bacterial competition in the gut.
