AMR OCTOBER, 2022

prepared by Marcus Wenne

In September, the EMBARK team got together to:
1. discuss current and future AMR research efforts and
2. have fun!!

If you live in the Northern Hemisphere every day is becoming darker and colder when we are steadily approaching winter. It is therefore extra important to illuminate your mind with interesting research and get that warm feeling in your body when reading a well written and structured paper. This is hopefully the feeling you will get when reading our October AMR digest. It touches the topics of evolution, the release of new databases, biofilms, wastewater and so much more. If you are from the Southern Hemisphere, you are of course equally welcome to take part of this interesting collection of papers!

Wastewater
Predicting selection for antimicrobial resistance in UK wastewater and aquatic environments: Ciprofloxacin poses a significant risk – April Hayes – Environment International

Microbiome and resistome dynamics along a sewage-effluent-reservoir continuum underline the role of natural attenuation in effluent receiving reservoirs – Inês Leão, Leron Khalifa, Nicolas Gallois, Ivone Vaz-Moreira, Uli Klümper, Daniel Youdkes, Shaked Palmony, Lotan Dagai, Thomas U. Berendonk, Christophe Merlin, Célia M. Manaia, Eddie Cytryn – bioRxiv

New methods, tools or approaches
Evaluation of FEAST for metagenomics-based source tracking of antibiotic resistance genes – Jinping Chen – Journal of Hazardous Materials

Determination and quantification of microbial communities and antimicrobial resistance on food through host DNA-depleted metagenomics – Samuel J Bloomfield – Food Microbiology

Quantification of the mobility potential of antibiotic resistance genes through multiplexed ddPCR linkage analysis – Magali de la Cruz Barron, David Kneis, Alan Xavier Elena, Kenyum Bagra, Thomas U. Berendonk, Uli Klümper – bioRxiv

Biofilm
Metagenomic insights into taxonomic, functional diversity and inhibitors of microbial biofilms – Madangchanok Imchen – Microbiological Research

Biofilm antimicrobial susceptibility through an experimental evolutionary lens – Tom Coenye – Biofilms and Microbes

Databases & resources

*ResFinderFG v2.0: a database of antibiotic resistance genes obtained by functional metagenomics – Rémi Gschwind – bioRxiv
A bioinformatic analysis is not better than the database and tools you base it on. Here Rémi
Gschwind et al. describes a new and updated version of ResFinderFG, version 2.0. According
to the authors most genes in antibiotic resistance gene databases mostly originate from
culturable and pathogenic bacteria. ResfinderFG 2.0 is instead a database based on a
literature search on studies identifying resistance genes using functional metagenomics.
This means that there is a reduced bias in the ResFinderFG v.2.0 database towards
culturable pathogens.


Ab-AMR: A Comprehensive Repository of Acinetobacter baumannii to Understand the Molecular Landscape of Antimicrobial Resistance – Tina Sharma – bioRxiv

CARD 2023: expanded curation, support for machine learning, and resistome prediction at the Comprehensive Antibiotic Resistance Database – Brian P Alcock – Nucleic Acids Research

*A curated data resource of 214K metagenomes for characterization of the global antimicrobial resistome – Hannah-Marie Martiny – PLOS BIOLOGY
Large scale metagenomic screenings of the worlds entire catalogue of metagenomic data
could potentially reveal interesting global and local patterns of antibiotic resistance.
Undertaking such a task is however way to computer intensive for most research groups to
undertake. Luckily, Hannah-Marie Martiny et al. have already undertaken this task. In this
paper they present a publicly available resource of antibiotic resistance gene abundance
based on 442 Tbp of sequencing reads from 214,095 metagenomic samples from the
European Nucleotide Archive.

AMR JUNE, 2022

prepared by Víctor Hugo Jarquín-Díaz

For those in the northern hemisphere… Summer is here ⛱️! With it, the EMBARK team brings a refreshing AMR digest with many sunshiny papers. Put your 🕶️ on and swim deep into many works that we have compiled for you: AMR in soil, water, clinical or livestock settings, antibiotic resistance gene ecology and evolution and more … for those in the southern hemisphere, we also wish you a happy reading despite the cold winter ^^

Global

*Addressing a future pandemic: how can non-biological complex drugs prepare us for antimicrobial resistance threats? – Blackman, L. D., Sutherland, T. D., De Barro, P. J., Thissen, H., & Locock, K. E. – Materials Horizons
Lewis D. Blackman et al. review the different ways in which bacteria develop resistance against antibiotics and alternative agents that could be employed. They focused on non-biological complex drugs (NBCDs) as the next generation antimicrobial agents. They outline the advancements in antimicrobial polymer materials, carbon nanomaterials, and inorganic nanomaterials and highlight the remaining challenges for their clinical translation.

*Environmental Dimensions of “One Health” to Combat Antimicrobial Resistance: Essential Research Needs – Jin, L., Pruden, A., Boehm, A. B., Alvarez, P. J., Raskin, L., Kohn, T., & Li, X. – Integrating Environmental Science & Technology
In this viewpoint article, Jin et al. critically address the lack of relevance and impact on health outcomes in environmental AMR research. They invite to “better define impactful contributions from the environmental dimension of AMR as part of a broader “One Health” vision” by implementing and developing models in line with an anthropocentric context of bacterial transfer within the interface between environment and humans. The authors promote multidisciplinary cross-national participation and coordination to establish analytical approaches to interpret ARG in the environment comprehensively. Approaches to identify responsible agents or conditions that select for AMR evolution and fit-for-purpose treatment technologies for mitigating high-risk ARGs and ARB at crucial sources.

*A bottom-up view of antimicrobial resistance transmission in developing countries – Ikhimiukor, O.O., Odih, E.E., Donado-Godoy, P. and Iruka N. Okeke – Nature Microbiology
This review from Odion O. Ikhimiukor et al. focuses on AMR transmission in low- and middle-income countries, emphasizing high-risk transmission points such as urban settings and food-animal handling. The authors describe the integration of top-down and bottom-up strategies as AMR-containment approaches. They suggest that technological innovations are required to control AMR in low- and middle-income settings.

Yi et al. focused their work on giving further insight into antimicrobial resistance in mining-impacted environments. They suggest developing constant monitoring strategies as the mining sites represent an underexplored hotspot for multidrug resistance genes. Overall, they described around 54 high-quality ARG-carrying MAGs from the phylum Proteobacteria, Acidobacteria, Actinobacteria, Bacteroidota, Firmicutes, Nitrospira, Planctomycetes and Thermoplasmatota and confirmed high mobility of ARGs, mainly trough transposons and plasmid.
