title: Serratia pneumonia.
abstract: The clinical and radiological manifestations were correlated with the necropsy findings in the lungs of 18 patients who died of Serratia marcescens infection. Ten died during a hospital epidemic affecting 74 patients. In 14, only Serratia was identified at autopsy; in 4, other organisms were also cultured. Ten patients had septicemia. The predominant radiological findings were focal bronchopneumonia in 13, lobar consolidation in 2, and diffuse nonhomogeneous infiltrates in 10. Small radiolucent areas within the infiltrates were seen in 5, a large pulmonary abscess in 1, and pleural effusion in 7. The predominant pathological findings were focal necrotizing bronchopneumonia (sometimes with microscopic abscesses) in 14 and diffuse hemorrhage in 3. Three patients had endocarditis and 3 others showed dissemination to the brain or kidneys.
