From acute to chronic and difficult-to-treat infections caused by S. aureus

A: S. aureus spondylodiscitis/osteomyelitis with vertebral body destruction; B: Pathogenesis steps in hematogenous osteomyelitis

Chronic and difficult-to-treat infections are a major research focus of our institute. We have long-standing experience with S. aureus infections that can develop from an acute destructive infection into a chronic infection that can be extremely difficult to treat. The reason for this can be that the pathogens (i) invade host cells and hide intracellularly, (ii) chance their phenotypes to small-colony-variants (SCVs) that have a low metabolism and can escape from the immune system and from antibiotics, and (iii) form biofilm. Important examples for chronic S. aureus infections are osteomyelitis and endocarditis. In several project we investigate the patho-mechanisms of the infections. For this, we have developed in-vitro cell culture and in-vivo murine models that can be analysed from the acute to the chronic stage. We investigate the bacterial adaptation strategies and the host response.

Currently, we have funding from the BMBF-consortium “Mesinflame”.

The lung microbiome and their influence on infection development

S. aureus colonies on a blood plate with large zones of hemolysis

Since many years we analyse lung infections caused by S. aureus, by influenza virus or by both pathogens (co-infections). We study different virulence factors that cause lung inflammation and destruction, such as the S. aureus pore-forming toxins. In the co-infection, both pathogens interact, which can aggravate pneumonia. In a recent project we study the lung microbiome and its impact on infection development. We analyse the microbiome in surgical samples in different locations of the lung by culture methods, by sequencing and by imaging techniques. Additionally, we established complex cell culture models, including the alveolar-on-a-chip model that mimics the situation in the lung. We aim to colonize our cell culture models with bacteria belonging to the microbiome and infect the system with pathogens. Thereby the role of the microbiota and possible therapeutic interventions will be studied.

Currently, we have funding from DFG by the Excellence Cluster “Balance of the Microverse” and the SFB 1278 “PolyTarget”

Project management: Bettina Löffler, in cooperation with Hortense Slevogt (Septomics)

Funding: BMBF im Rahmen des InfectoGnostics Forschungscampus

Diagnostic and translational research

To improve our diagnostic work we continuously aim to develop new methods. We have collaborations with the Leibniz Institute of Photonic Technology and use imaging methods to detect pathogens in diagnostic samples. In particular, we work on fast blood culture detection methods that can directly identify the pathogens in blood samples from patients with short (or no) cultivation steps. Furthermore, we work on rapid antimicrobial resistance testings that are based on early microbial changes that can be detected by imaging methods.

In general, we check newly developed techniques for their application in routine diagnostics, ranging from blood culture detection analytic methods to multiplex PCR systems designed for POCT-diagnostics.

Currently, we have funding by the BMBF by the InfectoGnostics Campus Jena, project “InfectoExplore” and “ADA” and by the BMBF-funding for the “Leibniz-Zentrum für Photonik in der Infektionsforschung”.

Projects

Development and evaluation of rapid molecular diagnostic assays

The focus of our research is the conception and evaluation of molecular assays based on loop-mediated isothermal amplification (LAMP) for the use as rapid diagnostic tests in routine laboratories. LAMP offers the potential to test sample without nucleic acid extraction in a very short turnaround time of ≤ 30 min.

Projects:

Rapid blood culture testing for identification of bacterial and fungal species and resistance marker genes
Identification of beta-lactamase genes in Enterobacterales isolates (ESBL, AmpC, and carbapenemases)
Differentiation of virulence factors of intestinal pathogenic E. coli, e. g. EHEC, in stool samples and culture isolates
Rapid Salmonella typing
Culture-independent diagnostics of deep tissue infections and endocarditis
Rapid diagnostic tests for respiratory viruses (Influenza virus, SARS-CoV-2)

Industrial partner for scientific cooperation: Amplex Diagnostics GmbH (Gars-Bahnhof, Germany)

Automation in microbiology

We work on the development of automatized workflows in culture-dependent microbiological diagnostics and the integration of automated PCR systems. Automated culture microbiology and PCR in the bacteriology laboratory was implemented by installation of the BD Kiestra Work Cell Automation (WCA) and BD MAX PCR systems. The aims of this work are:

To decrease the time of diagnostic reports including results of antimicrobial susceptibility testing
To increase the sensitivity and quality of culture microbiology by high-resolution streaking of cultures and improved conditions of culture incubation
To improve the surveillance of multi-resistant pathogens

Industrial partner for scientific cooperation: Becton Dickinson GmbH (Heidelberg, Germany)
