Human Lung Tissue (image) Helmholtz Centre for Infection Research Caption This image shows human lung tissue, which is infected by legionella as it can be seen by doctors when patients suffer from legionnaire's disease. By immunostaining of one legionella protein (redbrown) the bacteria-containing vacuoles and individual legionella inside the scavenger cells can be detected. The tissue was fixed with HOPE and thus the infection process can be observed immediately using proteomics.
