Two types of polymicrobial infections in chronic lung diseases
Chronic lung diseases are often accelerated and exacerbated by polymicrobial infections. An international study team led by MedUni Vienna has identified two types of these so-called dysbioses in cystic fibrosis. They display distinct ecology and are also likely to respond differently to treatment. The study was published in the journal ...
