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