Scanning and transmission electron microscopy study of ferret respiratory mucosa infected with influenza A virus.

The use of both SEM and TEM techniques in studying the alterations of the columnar ciliated epithelium of the whole respiratory tract of ferrets enables the authors to find a significant discrepancy between tracheal and nasal mucosa destructions. This discrepancy is not a function of the anatomical location of virus instillation. Theoretical and pratical meanings are discussed.
