Microbes turn back the clock as research discovers their potential to reverse aging in the brain

Research from APC Microbiome Ireland (APC) at University College Cork (UCC) published in the leading international scientific journal Nature Aging introduces a novel approach to reverse aspects of aging-related deterioration in the brain and cognitive function via the microbes in the gut. As our population ages one of the key global challenges is to develop strategies to maintain healthy brain function. This […]

Enzyme treatment of skin samples improves microbiome analysis

In many skin diseases such as atopic dermatitis and acne, the bacterial layer protecting the skin is damaged. “Our goal is to learn the role played in such illnesses by the various kinds of skin bacteria,” says Dr. Martin Köberle, head of the Dermatoinfectology Laboratory at the Klinikum Rechts der Isar of the Technical University of Munich (TUM). Past efforts […]

Our genes shape our gut bacteria, new research shows

Our gut microbiome — the ever-changing “rainforest” of bacteria living in our intestines — is primarily affected by our lifestyle, including what we eat or the medications we take, most studies show. But a University of Notre Dame study has found a much greater genetic component at play than was once known. In the study, published recently in Science, researchers discovered […]

A fermented-food diet increases microbiome diversity and lowers inflammation, study finds

A diet rich in fermented foods enhances the diversity of gut microbes and decreases molecular signs of inflammation, according to researchers at the Stanford School of Medicine. In a clinical trial, 36 healthy adults were randomly assigned to a 10-week diet that included either fermented or high-fiber foods. The two diets resulted in different effects on the gut microbiome and […]

Public health risk from multidrug-resistant bacteria in dog food

European Society of Clinical Microbiology and Infectious Diseases Research presented by Dr Ana R. Freitas, and colleagues from UCIBIO, Faculty of Pharmacy, University of Porto, Portugal, showed that dog food from supermarkets and pet shops was a major source of antibiotic-resistant bacteria, making it an international public health risk. With some of the multidrug-resistant bacteria in raw dog food identical […]

SARS-CoV-2 infection starts in nasal ciliated cells

Journal of Clinical Investigation The discovery that multiciliated cells in the nasal epithelium are the first cells to be targeted in early COVID-19 infection might provide the rationale for treatment using suitable antiviral nasal sprays. Led by Director KOH Gou Young, scientists from the Center for Vascular Research within the Institute for Basic Science, South Korea, have recently uncovered the […]

Persistence pays off in the human gut microbiome

The human gut microbiome is a complex community of trillions of microbes that are constantly interacting with each other and our bodies. It supports our wellbeing, immune system and mental health — but how is it sustained? Researchers in the UK and Germany, alongside other international collaborators, have investigated the evolution of bacteria in the human gut microbiome — asking […]

Mild COVID-19 induces lasting antibody protection, study finds

People who have had mild illness develop antibody-producing cells that can last lifetime Washington University School of Medicine Months after recovering from mild cases of COVID-19, people still have immune cells in their body pumping out antibodies against the virus that causes COVID-19, according to a study from researchers at Washington University School of Medicine in St. Louis. Such cells […]
