Electron microscopy of pathological alterations of nasal and laryngeal mucous membranes in infants and children.

Morphological methods were employed to reveal virus infections of the upper respiratory tract in infants and children. Two electron microscopic methods, negative staining and concanavalin-A-peroxidase reaction were compared. In viral infections epithelial cells of the mucose showed a markedly altered conacanavalin-A-peroxidase reaction.
