About Konstantina Zafeiropoulou

Konstantina Zafeiropoulou is a dietitian with strong scientific interest in the diet-microbiota interactions and their role in human health and disease. She holds a Master of Science in Human Nutrition from the University of Glasgow, during which she explored the involvement of gut microbiota in the etiopathogenesis of Celiac Disease and evaluated the gluten free diet-microbiota interactions. She is currently a PhD candidate at Amsterdam UMC unraveling the role of gut microbiota and long-term dietary patterns in the development of postoperative colorectal anastomotic leakage.

An international collaboration of scientists identified 248 viral families in nappy samples, 232 of which were never described before. Acknowledged for their contribution, these babies will be forever registered in the virome databases, as the scientists named the new families after their first names.

The Digestive Disease Week meeting 2023 covered a considerable variety of basic, translational, and clinical aspects of research in gastrointestinal and extraintestinal human health and disease. This post highlights the major takeaways from the Microbiome & Microbial Therapy sessions and unravels how they might impact daily basic research and clinical practice (part 2).

Just one month before friends and families gather around the Christmas table, November is here to bring awareness around Clostridioides difficile infection, and the importance of microbiota-derived treatments. With this post, all of us in GMFH aim to highlight the importance of protecting ourselves and families and stopping the spread of this potentially deadly infection.

Bacterial extracellular vesicles: future postbiotics?

Research into microbial extracellular vesicles has progressed significantly over several decades. Following up on the 1989 breakthrough that bacterial extracellular vesicles contain genetic information, and the recent ISAPP definition on postbiotics, current research suggests bacterial extracellular vesicles derived from probiotic bacteria may be the postbiotics of the future with potential health benefits.

The first 2-3 years of life are crucial for shaping childhood health. Amid others, the importance of early-life gut microbiota in infant’s development and later human health has been long speculated. In particular, bifidobacteria are playing an essential role in infant’s gut microbiota and immune system maturation that supports its probiotic use in that age span.

Bioaccumulation: a new perspective in the drug-bug story

24 Jan 2022

by Konstantina Zafeiropoulou

In Western world, the incidence of autoimmune and autoinflammatory diseases has been significantly increasing and also the use of non-antibiotic drugs for their treatment. Scientists at EMBL and Cambridge University elucidate how common drugs accumulate in gut bacteria and potentially reduce medication’s effectiveness.
