Das PANDASIA-Projekt untersucht, wie Infektionskrankheiten zwischen Tieren, Menschen und der Umwelt übertragen werden und wie potenzielle Pandemien entstehen. Die Ergebnisse werden genutzt, um die Gesundheitskompetenz verschiedener Zielgruppen in Thailand und Europa zu verbessern.
Neu auftretende Infektionskrankheiten, die durch Erreger wie Viren und Bakterien verursacht und zwischen Tier und Mensch übertragen werden, stellen eine zunehmende Bedrohung für die globale Gesundheit dar. Diese sogenannten Zoonosen treten vor allem dort auf, wo Wildtiere und Menschen regelmäßig in Kontakt kommen. Aufgrund hoher Artenvielfalt, Bevölkerungsdichte und Mobilität der Menschen gilt Südostasien als Hotspot für das Auftreten neuer Zoonosen und Pandemien. Der Klimawandel und der Biodiversitätsverlust erhöhen das Risiko neuer Pandemien. Das von der EU finanzierte, transdisziplinäre wissenschaftliche Projekt „PANDASIA“ untersucht potenzielle Risiken für neue Pandemien in Thailand und entwickelt Präventivmaßnahmen. Die Ergebnisse werden genutzt, um die Gesundheitskompetenz verschiedener Zielgruppen und Gemeinschaften zu verbessern.
By using bacterial whole genome sequencing, scientists from the Leibniz Research Alliance INFECTIONS showed that contaminated houseflies (Musca domestica) carried antimicrobial-resistant bacteria from agriculture farms into urban habitation areas.
As part of their research, the team examined a pig farm in Brandenburg, Germany, and its surrounding area for the presence of antimicrobial-resistant bacteria of the genus Escherischia coli (E. coli). This enterobacterium can cause severe urinary tract and intestinal infections in humans that can lead to death.
The results of bacterial genomic analysis could show that a large number of E. coli bacteria showed resistance in the samples and that contaminated houseflies carried these bacteria from the farm over distances of at least 2 km to urban residential areas. The observed proximity of contaminated flies to human households poses a risk of transmission of antimicrobial-resistant enteric pathogens from livestock to humans.
Scientists from the DSMZ - German Collection of Microorganisms and Cell Cultures-, the Leibniz Centre for Agricultural Landscape Research (ZALF) e. V and the Leibniz Institute for Agricultural Engineering and Bioeconomics (ATB) were involved in this work. The results have now been published in the current issue of the journal Environmental Microbiology.

Press release of the Leibniz Institute for Zoo and Wildlife Research from January, 13, 2023
Madagascar is home to a unique biodiversity with a large number of endemic species, among those many lemur species, including the mouse lemurs. This diversity is also found in their retroviruses, a team led by scientists from the Leibniz Institute of Zoo and Wildlife Research (Leibniz-IZW) and the University of Stirling reports in the journal “Virus Evolution”. They analysed the mouse lemur genome and identified viruses of two classes that represent ancient infections of the mouse lemur germline. The viruses now behave similarly to lemur genes and are thus called endogenous retroviruses (ERVs). It was surprising that some of the identified retroviruses are closely related to viruses found in other, very different mammals such as polar bears or domestic sheep. This suggests an intriguing and complex pattern of host switching of retroviruses, much more complex than previously thought.
On Jan. 24, 2023, a panel discussion on "The spread of antibiotic-resistant germs as a global crisis" took place at the Hessian State Representation in Brussels, to which Prof. Ulrich Schaible, spokesman of the Leibniz Research Network (LRA) INFECTIONS, was invited. The event was livestreamed and is now available to all interested viewers in the aftermath.

International Symposium of the Leibniz Center Infection
Hamburg. The multiple strategies of infectious pathogens to survive and multiply in the host and how we might use these sophisticated strategies to better fight the pathogens are the focus of this year's symposium "Compartments in Infection" of the Leibniz Center Infection (LCI). On January 26 and 27, 2023, international researchers will gather at the Bernhard Nocht Institute for Tropical Medicine to discuss this topic.
