One or two membranes? Evolution of the cell envelope across Bacteria

Simonetta Gribaldo (France)

Short biography:
Simonetta Gribaldo is full professor and Head of the Unit Evolutionary Biology of the Microbial Cell at the Department of Microbiology, Institut Pasteur, Paris. She is an established figure in the field of large-scale microbial evolution, with an original and broad vision on the whole Tree of Life. Professor Gribaldo has significantly impacted the of Microbiology and challenged widely held paradigms. Recently, she has taken up the challenge of setting up an experimental laboratory to complement her bioinformatics studies. Since then, she has contributed seminal insights on the evolution of the bacterial cell envelope. Notably, she has inferred an ancient origin of the outer membrane and multiple transitions from Gram-negatives to Gram-positives. To test in-silico generated hypotheses, Professor Gribaldo has developed a new experimental model, the diderm Firmicute Veillonella parvula.

Adrian Egli (Switzerland)

Short biography:
After studying medicine at the University of Basel (MD 1998 – 2004, PhD thesis 2006 – 2008) at the University of Basel, Adrian Egli went abroad for a Clinical Fellowship “Transplant Infectious Disease” as well as a Post-doctoral fellowship, Li Ka Shing Institute for Virology (2010 – 2011), both at the University of Alberta, Canada. Back in Switzerland, he became a fellow in Clinical Microbiolgy (FAMH) (2012 – 2015) at the University Hospital of Basel. During the same period (11/2014 – to date) he was appointed as Research Group Leader “Applied Microbiology Research” in the Department of Biomedicine of the University of Basel. Finally, in November 2019, he became a Professor. Between September 2015 to July 2022, he held the position as Head of Department, Clinical Microbiology at the University Hospital of Basel. Starting in August 2022, he was appointed as the new Director of the Institute of Medical Microbiology, University of Zürich, a position that he is still holding at present.

Complicated seroprofiles in HBV

Hans Zaaijer (Sanquin)

Summary
The interpretation of hepatitis B serology, as encountered in clinical diagnosis and in routine donor screening, is notorious. On one hand simple rules of thumb apply, but there is an exception to each rule. HBsAg/anti-HBs and eAg/anti-e are presumed to be mutually exclusive, but they may concurrently be present or absent. Anti-HBcore antibodies may vanish in hematological and HIV patients, but in otherwise healthy HBV carriers too. Even the appearance of HBsAg during productive HBV infection sometimes is lacking. For correct interpretation of HBV serology, a two-staged approach may be helpful.

Chemical imaging-based insights into the human gut microbiome drug interaction network

Michael Wagner (Austria)

Short biography:
Michael Wagner is full professor for Microbial Ecology at the University of Vienna, Austria and a Distinguished Professor (20%) at Aalborg University, Denmark. He was the founding director of the Centre for Microbiology and Environmental System Science (CeMESS), which is a 2019 founded new faculty at the University of Vienna. His main research interests are single cell methods in microbiology and nitrogen-cycle microbiology. His team developed several innovative chemical imaging methods for directly studying functional properties of individual microbial cells within complex microbiomes. Recently, they spearheaded the application of these techniques to investigate drug-microbe interactions in the human gut. In the nitrogen cycle field, he discovered together with colleagues in 2015 complete nitrifying microbes (so-called comammox organisms) demonstrating that nitrification is not always a two-step process. Subsequently, they showed that comammox organisms are green nitrifiers producing much less nitrous oxide than classical ammonia-oxidizing bacteria. Michael Wagner has been continuously recognized as a highly cited scientist since 2014 and received an ERC Advanced Grant as well as the Wittgenstein award (the highest science award in Austria). In 2023 he became director of one of the five Austrian Clusters of Excellence entitled “Microbiomes drive Planetary Health“ in which 30 PIs from 8 leading Austrian research institutions focus on environmentally and medically relevant microbiomes.
