Mechanisms of bacterial interactions with human pathogenic fungi − the interaction between Aspergillus fumigatus and Pseudomonas aeruginosa

Interactions between bacteria and fungi have major implications for the environment, agriculture and medicine. Little is known about the interactions between medically important bacteria and pathogenic filamentous fungi despite the fact that their interaction can have dramatic effects on the outcome of human disease. In this proposal we focus on the interaction between the pathogenic fungus Aspergillus fumigatus and the pathogenic Gram-negative bacterium Pseudomonas aeruginosa. Both are the most prevalent microbes in cystic fibrosis (CF) patients which underlines the relevance to study their intermicrobial communication processes. Until know, very little is known about the molecular interaction between both microorganisms as well as the impact of a co-infection for pathogenesis of CF. Our preliminary data suggest that unique antimicrobial compounds are produced in A. fumigatusP. aeruginosa co-culture. We will use a combination of genetic, transcriptomic and biochemical approaches to identify novel fungal and bacterial effectors specifically induced during co-cultivation, allowing the opposing organism to inhibit or modulate its partner. Our proposal will also analyze at the molecular level the interaction between strain pairs consisting of a clinical CF isolate and a laboratory control strain of both organisms. In addition to reveal novel mechanisms governing microbial interactions and antibiosis, we expect to identify novel antifungal and antibacterial secondary metabolites (SMs) whose biosyntheses are triggered by the interaction.

We expect:

  • a Master's degree (or equivalent allowing you to pursue a PhD degree) in Natural or Life Sciences. Research at ILRS is centred around “Microbial and Biomolecular Interactions”. Candidates about to earn their degree are welcome to apply.

  • experience in cloning, transformation, genetic engineering, cultivation of microorganisms

  • high motivation to join one of the research areas of ILRS

  • creativity and interest in shaping your own cross-disciplinary thesis project

  • an integrative and cooperative personality with enthusiasm for actively participating in our lively community

  • very good communication skills in English, the working language at the ILRS.

We offer:

  • a top-level research environment

  • efficient supervision by a team of advisors

  • a comprehensive mentoring programme

  • courses in state-of-the-art technologies and soft skills

  • strong communication and interaction between the involved institutions

  • Jena - City of Science: innovative business activities, successful scientific centres and a vibrant cultural scene around the famous Friedrich Schiller University

The three-year Doctoral Researcher position is available starting from January 2018. The position will be financially supported according to TV-L (salary agreement for public service employees). HKI is an equal opportunity employer.
