Infection Microbiology

The Infection Microbiology Group investigates bacterial airway infections in patients suffering from the heritable disease cystic fibrosis (CF).

The majority of the CF patients live with bacteria in their lungs from early childhood until they die prematurely. In our project we focus on translational biomedical research based on three important questions:

  1. Why is it not possible to kill the bacteria with antibiotics?
  2. How do the bacteria change during their long persistence in the CF airways?
  3. How can we – using the answers to the first two questions – get more efficient treatment of the patients and thus improve their life expectancy?

Cystic fibrosis patient

We study bacterial infection in CF patients, because it is an excellent model for infectious diseases for which antibiotic treatment is challenged by frequent lack of success. Equally important is that modern human life-style and increases in the average population life span will create problems with long-term bacterial infections that are difficult or impossible to treat.

Moreover, the rising global problem of antibiotic resistance threatens to become the biggest health risk within the next 20-30 years. Our research is directly addressing the problem of antibiotic resistance.

Over the last few years, we have introduced methodologies, which are also applied by cell factory designers at the Center, in order to clarify how the bacteria avoid eradication by antibiotics or by the host immune system. This work has clearly shown that several previous explanations are not sufficient or wrong, and it is therefore important to address new challenging questions concerning the fights against microbial infections.
