title: [Clinical picture of bacterial pneumonias and their differential diagnosis].
abstract: Under the influence of antibiotic therapy, bacterial pneumonias have undergone a remarkable change in the last few decades. Individual forms of pneumonia can be distinguished morphologically by their localization, the way in which they spread, their limitations, and their course. Clinically, opportunistic bacterial infections predominate. Increasingly, secondary pneumonias are observed in poststenotic areas, areas of infarction, in hypostatic areas, after aspiration, and in previously damaged lobes. Radiologic criteria for differentiating from atypical pneumonias (viruses, mycoplasmas and chlamydia) are discussed.
