428. Predicting environmental susceptibility to antimicrobial-resistant bacterial invasion using biodiversity and phylogenetic structure

Uli Klümper (TU Dresden)

10/7/26, 11:30 AM

AMR

Oral presentation

Antimicrobial resistance (AMR) can spread through freshwater systems when resistant bacteria enter river biofilms, yet predicting which communities resist such introductions remains difficult. Biotic resistance theory predicts lower invasion success in more diverse communities, but whether this applies to natural biofilms under change is unclear.

We collected epilithic biofilms from 30...

457. One Health Surveillance of Antimicrobial Resistance in Integrated Constructed Wetlands

Ms Gaia Streparola (Teagasc Food Research Centre, Food Safety Department, Ashtown, Dublin, Ireland. School of Veterinary Medicine, University College Dublin, Dublin, Ireland)

10/7/26, 11:45 AM

AMR

Oral presentation

Antimicrobial resistance (AMR) is a major One Health challenge linking human, animal and environmental health. Wastewater systems are recognised as reservoirs of antimicrobial-resistant organisms (AROs), facilitating their dissemination into natural ecosystems. Integrated Constructed Wetlands (ICWs) are nature-based wastewater treatment systems that combine water treatment with biodiversity...

475. Comparison of antimicrobial resistance in conventional and organic pig production in Germany

Bernd-Alois Tenhagen (Bundesinstitut für Risikobewertung)

10/7/26, 12:00 PM

AMR

Oral presentation

We compared antimicrobial resistance in E. coli and the prevalence of cephalosporin resistant E. coli in organic and conventional fattening pigs and their derived meat in Germany. Boot sock samples were collected from 368 conventional and 131 organic pig farms. At retail, 430 and 306 samples from fresh conventional and organic pork, respectively, were collected. E. coli were isolated using...

349. Prevalence of antimicrobial resistance bacteria in dust from piglet farms.

Elisabeth Pfrommer (RKI)

10/7/26, 12:15 PM

AMR

Oral presentation

Dust can contain microorganisms that are both pathogenic and resistant to antimicrobials (AMR), which can potentially transmit airborne human pathogenic bacteria. Agriculture is one of the largest producers of primary particle matter, accounting for approximately 20% of global fine dust emissions. While it is known that the use of antibiotics in agriculture often results in...

496. Syntheses of KAP surveys on AMU and AMR in livestock across Ethiopia: implications for one health and informed decision

Mr Tenaw Andualem Tadege (Food and Agriculture Organization of the United Nations)

10/7/26, 12:30 PM

AMR

Oral presentation

Introduction: Knowledge, Attitudes, and Practices (KAP) of livestock farmers and animal healthcare providers (AHCPs) regarding antimicrobial use (AMU) and antimicrobial resistance (AMR) are critical for advancing One Health and monitoring interventions.
Methods: We synthesized cross-sectional KAP surveys, 2020–2024 livestock owners and AHCPs using structured questionnaires on AMU and...

492. Molecular Surveillance of Extended-Spectrum Beta-Lactamase- and Carbapenemase-Producing Escherichia coli from one health interface in Ado-Ekiti, Southwestern Nigeria

Fiyinfoluwa Ojeniyi (APIN PUBLIC HEALTH INITIATIVES)

10/7/26, 12:45 PM

AMR

Oral presentation

Carbapenem-resistant and ESBL-producing Escherichia coli at the human-animal-environment interface represent an escalating One Health threat. This study characterised ESBL- and carbapenemase-producing E. coli from five One Health source compartments in Ado-Ekiti, Nigeria. Five hundred samples (n=100 per group) were processed; MALDI-TOF MS confirmed identifications; EUCAST 2021 susceptibility...
