PNEUMONIA IN INFANTS: DUE TO BACILLUS MUCOSUS-CAPSULATUS

Pneumonia in infants due to Bacillus mucosus-capsulatus is extremely rare. Comba, 1 in 1896, reported a case in an infant 6 days old. In his case autopsy revealed bronchopneumonia, and pure cultures of B. mucosus-capsulatus were obtained from the heart's blood and the exudate from the lungs. Mark Jampolis and his associates 2 have reported a series of twenty-two cases of infection of the intestinal tract in infants caused by B. mucosus-capsulatus. Friedlander's bacillus was recovered from the lungs in three of seven cases; that is, nearly 43 per cent of the cases that came to autopsy showed pneumonia due to Friedlader's bacillus. These authors stated that the observations made on gross examination of the lung were not typical of Friedlander's pneumonia, but suggested the explanation that the pneumonia was in a very early stage. Pneumonia in adults caused by the Bacillus mucosus-capsulatus group of bacteria is not uncommon. It
