Abstract
In previous publications1 from this hospital, my associates and I described the clinical and roentgenologic features of three cases of pneumonia with recovery and expressed the belief that the organism responsible for the production of the pulmonary lesion was the Friedländer bacillus (Bacillus mucosus-capsulatus). In two of these cases the onset suggested bronchopneumonia; in one, lobar pneumonia. The temperature fell by lysis in all cases, and in all the total leukocyte count tended to be lower than that seen in the usual case of pneumococcic lobar pneumonia. The outstanding finding on physical examination was the extreme indolence of the lesion in the lung. We expressed the belief that there are characteristic roentgen signs which serve to differentiate this condition from other pulmonary infections. Several months after the acute infection had subsided, evidence of pathologic change in the lung could still be demonstrated both by physical and by roentgen examination. On
