Preparing for historical specimen sampling

Story

From 4 to 6 June 2025, the Department “Pathogen Evolution” led by Prof. Dr. Sébastien Calvignac-Spencer at the Helmholtz Institute for One Health (HIOH) conducted a combined retreat and sampling mission at the Institute of Pathology of the University of Veterinary Medicine Vienna — a key collaboration partner for accessing and studying historical pathological specimens in veterinary medicine. HIOH is a site of the Helmholtz Centre for Infection Research (HZI). The visit focused on collecting around 60 historical tissue samples for molecular genetic analyses related to animal disease research, while also offering time for internal discussions on lab optimization, project development, and team building.

If an intestinal inhabitant such as the bacterium Escherichia coli (E. coli) becomes resistant to many antibiotics, it can cause serious health problems if it enters the bloodstream. How can such potentially dangerous multi-resistant bacteria be effectively removed from the gut? Researchers from the Helmholtz Centre for Infection Research (HZI), in collaboration with researchers from Hannover Medical School (MHH), explored this question in their latest study.

Pseudocolored cells of Pseudomonas aeruginosa

News

An international research team led by the Helmholtz Centre for Infection Research (HZI) has discovered a new strategy used by the human pathogen Pseudomonas aeruginosa to adapt to its host. In the journal Proceedings of the National Academy of Sciences (PNAS), the researchers demonstrate that epigenetic processes can lead to the emergence of distinct sub-populations within genetically identical bacterial populations. This heterogeneity may be a key for bacteria to establish successful infections.

Habitat loss, climate change, and globalization create new transmission routes for pathogens. Therefore, the One Health approach considers humans, animals and nature together. Prof. Fabian Leendertz is founding director of the Helmholtz Institute for One Health (HIOH) in Greifswald, which links health research, ecology, and prevention to better prepare for future pandemics. In this episode of the HZI podcast “InFact”, Leendertz explains how zoonoses, or diseases that jump from animals to humans, develop, and why protecting the environment is central to this process.

A research project at the Helmholtz Institute for One Health (HIOH), a site of the Helmholtz Centre for Infection Research (HZI), has been awarded the Undine Award 2025 in the “Habitat” category. The prize was presented in Stuttgart. In the award-winning project, a research team led by Prof. Katharina Schaufler is investigating antimicrobial resistance (AMR) in the surface water of the Greifswald Bodden. Targeted science communication is also an important part of the project in order to raise public awareness of the issue. Schaufler heads the department “Epidemiology and Ecology of Antimicrobial Resistance” at the HIOH and receives prize money of 20,000 euros and an image film with the Undine Award.

Researchers at the Helmholtz Centre for Infection Research (HZI) have contributed to a study by the Medical Center Hamburg-Eppendorf (UKE) that has uncovered a new mechanism of neuron damage in the autoimmune disease multiple sclerosis (MS). Until now, it was unclear how inflammation in MS reduces protein degradation and leads to their harmful accumulation in neurons. A combination of new molecular biological, biochemical, and genetic methods enabled the international research team to identify a previously unknown mechanism of impaired protein degradation in inflamed neurons and its key regulator, the immunoproteasome.
