Funding for an interdisciplinary research centre funded by the University of Gothenburg 2016-2022 and hosted by the Institute of Biomedicine. In total ~50 MSEK is budgeted, with 21.4MSEK allocated the first three years. Joakim Larsson and Fredrik Carlsson are main applicants, and in total 30 principal investigators from six faculties and three core external partners are engaged in the centre (see figure).
Main research themes of CARe and the different core partners involved. The theme interventions integrate with all other themes. Education & outreach activities cover all themes.
The threat of antibiotic resistant bacteria is a multifaceted challenge with high demands on interdisciplinary research. CARe will take advantage of diverse expertise representing six faculties and a broad network of stakeholders within the health care sector and beyond to generate state-of-the-art science with the intention to support rapid revision of policies and their implementation. Our work is divided into themes corresponding to the strategic research agenda of JPI-AMR, i.e. diagnostics, surveillance, transmission, environment, therapeutics and interventions. We will, when relevant, focus on resistance to carbapenems within each theme. CARe will provide opportunities for and stimulate internal and external collaborations as well as education, outreach and international engagement. The ultimate vision of CARe is to limit mortality, morbidity and socioeconomic costs related to antibiotic resistance on a global scale. Please visit CARe's website to read more.
Project funded jointly by the Swedish Research Council VR (Medicine and Health) (0.7 MSEK/year) and the Swedish Research Council FORMAS (1 MSEK/year) for the period 2016-2018.
Harmless environmental bacteria serve as sources for antibiotic resistance genes and resistance plasmids that over time are recruited into human pathogens through horizontal gene transfer. There is a widespread concern that very low, environmental levels of antibiotic residues, derived from human usage, exert selection and increase the risks for such transfers events. In some contrast to this concern, we conclude that there is still very limited scientific evidence supporting this risk scenario. By defining concentrations that select for resistance and drive gene transferin complex microbial communities, we will investigate if resistance promotion primarily, or even only, takes place at higher environmental antibiotic concentrations reached through other routes than via human excretions, such as pollutionfrom antibiotic manufacturing. We will also investigate if industrial pollution with antibiotics promotes the emergence of previously unknown resistance factors. We expect the results to significantly improve our scientific understanding of the role of antibiotics in the environment in the emergence, selection and transfer of antibiotic resistance. Importantly, the research will aid in scaling and directing countermeasures to where they are likely to have an impact, and thereby benefit public health in the long term.

One of the primary goals for Gothenburg Centre for Marine Research is to coordinate marine environmental research in Gothenburg and to bring together scientists from different disciplines. This interdisciplinary project combines competence from the Health Faculty and the Natural Science Faculty to address potential drivers for the development of antibiotic resistance, one of the most urgent threats to human health globally. Bacteria often carry resistance elements to metals and biocides together with resistance elements to antibiotics. Thus, a selection pressure from metals and biocides may select also for antibiotic resistance. By combining our competences in large-scale DNA sequencing and bacterial biofilm ecology, this project will address the risks for the promotion of antibiotic resistant bacteria, through indirect selection pressures, in the marine environment.
Strong Research Environment funded by the Swedish Council for Environment, Agricultural Sciences and Spatial Planning (FORMAS) 2012-2016 with 25 MSEK. The program, coordinated by Dr Thomas Backhaus, involves 12 partners from the Gothenburg region. The JL group is mainly involved in work on bacterial metagenomics.
Mixtures of toxic chemicals regularly occur in our coastal ecosystems. NICE develops instruments for monitoring their ecological effects, as required by the Water Framework Directive and needed for identification of the relevant pollutants in the field. The NICE tools will be evaluated in field studies. We will suggest options for environmental regulation of chemical mixtures, thus providing input to the water management in Västra Götaland. Reference and contaminated sites mainly on the Swedish coast will be selected in co-operation with stakeholder authorities and subjected to deeper ecotoxicological investigations. Chemical monitoring data will initially be used for pinpointing the pollutants at each site. These will be ranked according to their expected environmental impact and then further investigated by extended chemical analysis. Ecotoxicological effect profiles ("fingerprints") of the priority pollutants will be recorded for microbial communities, invertebrates and fish, using classic biomarkers, population level endpoints, ecological effect indicators (PICT) and advanced fingerprints based on (gen-)OMICs. The fingerprints will be used to detect effects in the environment, providing causal links between the mere presence of pollutants and their ecological impact of a site. The effect profiles will be aggregated into models for site-specific ecological impacts, which will be amended, if needed, to take into account the presence of unknown pollutants and interactions.

The accelerated development of antibiotic resistance is one of the most urgent threats to human health. Bacteria become resistant to antibiotics by acquiring resistance genes through the process of horizontal gene transfer. Since antibiotics are naturally produced by many organisms, environmental bacterial communities contain a particular high diversity of resistance genes. Understanding the role of the environment as a reservoir for resistance genes and their routes of transfer is therefore vital. In this project we will develop novel tools for explorative analysis of resistance genes in bacterial communities. The tools are based on data generated by the next generation DNA sequencing and have therefore a high sensitivity and precision, even for less abundant genes. We will also develop tools for culture-independent characterization of resistance plasmids, which are the main vehicles for transmission of resistance genes between bacterial cells. The methods will be used to analyze data from environmental bacterial communities, both with and without antibiotic selection pressure, and the human microbiome. The project will generate novel insights into the development, promotion and spread of antibiotic resistance. The methods will have a great applicability in both basic and clinical microbiology as well as in metagenomics in general.

In metagenomics communities of microorganisms are studied by observing random fragments of their genomes. The potential of metagenomics have increased with the introduction of next generation DNA sequencing and it constitutes today an important measurement technique in ecology, ecotoxicology and medicine. Metagenomics is however limited by high levels of technical and biological noise, the low number of samples and the high dimensionality of the observed data. In this project we will develop novel statistical methods for analysis of gene count abundance in metagenomes. We will model the complex structure of metagenomics data and develop robust estimators for the biological variation between metagenomes. We will also develop new methods for normalization of metagenomes with varying taxonomic composition. The methods will be applied in three collaborative research projects where metagenomics is an essential measurement technique. The methods will also be implemented in a software package that will be freely available for the microbiology research community. The statistical methodology developed within this project will improve the performance of metagenomics and thus the study of uncultured microorganisms in general.
