Bacteriological Studies in Epidemic Dropsy

Bacteriological studies of resected pulmonary tuberculosis lesions.

The solid lesions were enucleated and the cavities were sectioned for bacteriologic examinations. Materials obtained from small foci or clusters were handled separately. Fresh bronchial and pneumonic secretions were also examined. Direct smears were made from all of the materials studied. The “cold” staining technique (modified), based on the original Kinyoun method, was used. The materials fro...

Clinical and bacteriological studies with clindamycin.
